Yes, Of course.

Don't have much time to help you however, need to spend the little time
I have available on u-boot.

I am very interested.  Do you have the code posted somewhere?

This porting based on libcedarx(a wrapper library used libvecore, instead of libcedarv, lower level API than libcedarv).

I want to push it into github.

I hope more people will join the development.

BTW, how to post message into arm-n...@lists.phcomp.co.uk?

My mail seems to be filtered out.

Before posting you need to subscribe to the list and maybe wait for moderation approval. Anyway, you should post linux-sunxi stuff here, in this mailing list, ARM-Netbook is generic mailing list not headed just for sunxi. Afaik we did notice arm-netbook about this mailing list, so people who was interested in sunxi are already here.

I plan to push libcedarx today.

Can you refactor that to use the lib and headers from our cedarx-libs repo as external instead? Leaving only the vlc-related code here so to avoid a maintenance and license  mess.

Thanks!

  What's you plan?

I thought Linux based video players / media centers such as VideoLAN or XBMC on A10 could not be developed due to poor CedarX libraries. Has anything changed in this regard?
Or is it just that it can work, but it's just many video files won't be able to be played?

The libs aren't perfect, but empat0
<https://github.com/empatzero/xbmca10> got basic xbmc support working
without hackery and using the same old libs. It seems more coding,
reading and testing than politics, pride and whining did the trick.

We recently received debian/ubuntu armhf libs
<https://github.com/linux-sunxi/cedarx-libs>.

See <http://linux-sunxi.org/CedarX> and <http://linux-sunxi.org/XBMC>
for more details.

Yes, much.

The CedarX libraries are much better understood now, and more people are
working on integrating them, this time in the open, and available for
hardfloat as well.

There is support for most formats, in addition to software decoders
there is hardware acceleration for many formats. But it's unclear which
formats works well.

I just come across this: http://comments.gmane.org/gmane.comp.hardware.netbook.arm/3454

Seems some one have already patched ffmpeg libraries for CedarX. It save tons of work since most media player utilize ffmpeg, such as VLC ;)

But I couldn't find the patched ffmpeg, does anyone knows?

No. That is an old discussion on what would be required to do it, not
that someone have done it.

In the first reply,  the guy called lkcl luck says ffmpeg done already. I am a bit confusing though.

OK, i intend to do it after the next version of libcedarx.

I want to use cmake instead of autotools in next version because i can't install prebuild binary library by autotools, such as libvecore.so.

In next version, i will use libvecore.so from https://github.com/linux-sunxi/cedarx-libs.

Please, move to armhf (arm hard float) target rootfs and cross compiling toolchain, we have armhf Mali-400 libraries and armhf CedarX libraries, so nothing limits us to armel (arm soft float) anymore.

You need type "make install" to install lincedarx header.

Thanks Wills.

While I am execute vlc ./configure, i have to specifically disable a few modules/features:

I think i have a few packages missing. Working on it ;)

[Tim Feng]

After installed couple packages, ./configure works for me:

  sudo apt-get install libxcb-composite0-dev libxcb-xv0-dev

Although I have to disable a few moduels/features:

 ./configure --host=arm-linux-gnueabi --disable-mad --disable-postproc --disable-a52  --disable-qt4 --disable-skins2 --disable-libgcrypt --enable-cedar --prefix=${PWD}/install

During the compiling, it complained about zlib.h, zconf.h missing, as well as libdbus-1.so. I copied them from my arm rootfs to corresponding folders in /usr/arm-linux-gnueabi/, then it went through.

Then I got:

avio.c:76:5: error: unknown type name 'URLContext'

Thank you, I was able to test and compile everything on armel rootfs, but for armhf using libcedarxalloc.a is really not going to happen. It was replaced with https://github.com/linux-sunxi/cedarx-libs/tree/master/libcedarv/linux-armhf/adapter/avheap (also one more blob gone opensource and readable). Please, convert your work for armhf and use our cedarx sources, they seem to be newer than armel and also will totally be faster. For many users Linaro is default rootfs and it is armhf. Our new sunxi-bsp will probably produce armhf image too.

Anyway, thanks for your work!

Yes, of course I have, X11 runs fine both with FBDEV and xf86-video-mali. My resolution is 1080p VGA, I set it in script.bin.

Might be that you are using older kernel before libv changed a lot of stuff in /dev/disp, check http://linux-sunxi.org/Sunxi_disp_driver and drv_display.h is now https://github.com/linux-sunxi/linux-sunxi/blob/sunxi-3.0/include/video/sunxi_disp_ioctl.h You should not rely on /dev/disp anyway because it will vanish at some point. Having such device is not a "linux way", everything will be replaced.

Also, is it possible to use CedarX as a codec only? We can show picture with X11/SDL/EGL outputs that might work (first two work fine in default VLC), if CedarFB relies on /dev/disp too much because of the default Cedar implementation from allwinner sources, we should fix that.

In my platform

8% CPU at 720p H264 mkv

[wills]

About your question:

1.Is fb0_scaler_mode_enable/fb1_scaler_mode_enable needs to be disabled for cedarfb?

  Video rendering need a scalable layer because of different video resolution.

2.No output modules support apart from cedarfb which uses raw framebuffer access (not compatible with xf86-video-mali and any other driver/device that wants to write raw at the same moment).

  The picture format of cedar output is private, other display back-end can't process this format, we must use scaler engine from A10 display unit.

3.No support for GUI of the VLC, only command line VLC is supported

  As above, you have no way to render picture into the UI widget buffer.

4.1080p and such movies with high bitrate sometimes buffer too slow and frames are dropping.

  Need test and fixup.

5.No support for OSD because of lack of YUV420

  As above, because of private pixel format, you can't overlay anything into picture.

[wills]

Vlc have some bugs about CPU occupancy,  you can remove the audio  plugin "resample" or disable  this  plugin when compiling.

[Dmitriy B.]

So there is no way to write decoder from CedarX output to something more usual and feed this to, for example, X11 window? 

VLC has wide range of output modules (xcb, x11, xvideo, SDL, GLX, EGL, direct framebuffer access, file output), we can even implement something like null output framebuffer, draw it offscreen, capture it and send into GUI with scaling done software. Sounds horrible, though, but thats only first idea.

[Dmitriy B.]

Yeah my VQ1 movies are from my friends HDD from 5.1 home theatre, might be VLC is going hard decoding all 6 channels and resampling them to our ALSA outputs. Need to check that.

2012/11/13 Dmitriy B. <rzk...@gmail.com>

[Dmitriy B.]

XBMC (http://linux-sunxi.org/XBMC) can use CedarX and draw On-Screen Display without problems, they even have EGL acceleration of drawing the GUI planes and etc. Might be the source of solution for this problem. Sources for XBMC for A10 is available.

[wills]

No DRI, you must do memcpy 3 times for every frame as follow, the performance is very very low, .

decoder----------->scaler ----------- >video out(widget buffer) ----------- >FBDEV

           hw dma           sw copy                                    sw copy

In current source, the follow like this:

decoder -----------> FBDEV  

           pointer handle 

In this way, it isn't possible for decoding 1080P smoothly.

Actually, Xf86-video-mali just work on FBDEV, no any hardware acceleration.
If video out can do DRI, like this

decoder -----------> scaler ----------- >video out(widget buffer)-----------> FBDEV  

           hw dma            pointer handle                           pointer handle 

I think it is meaningful to do convertion.

Do you use this code base?

Great!

I really worked perfectly.
Does anyone know if there is a port for gstreamer?

Thanks!!!

[Dmitriy B.]

Yes, xf86-video-mali does DRI/DRI2 rendering and thats what it is wrote for. Just render the output from Mali libraries and place it to FBDEV. Check https://github.com/linux-sunxi/xf86-video-mali for "ready to go" version. Be aware that this driver is really is not in the best condition in terms of code quality, it is done with old X11 API and is compatible with xservers only up to 1.12.x, 1.13.x changed the API and many stuff behind rendering driver to just segfault trying to call the fbdev module. This means that Gentoo and ArchLinux-ARM guys are out of the loop for now.

Also looks like thats how it is done in XBMC, they render CedarX output to 2D texture and show it using EGL. Check https://github.com/rellla/xbmca10/blob/master/xbmc/cores/VideoRenderers/LinuxRendererA10.cpp for details.

About the pixel format conversions, there is a bunch of conversions ported to NEON https://github.com/willswang/vlc/tree/master/modules/arm_neon, can we use them? Looks like in XBMC only yuv2rgb is used.

Awesome! Please form a pull req. to this repo https://github.com/rzk/xf86-video-mali/commits/r3p0-04rel0 or send a proper git patch to this mailing list.

This is my "development" repo, main linux-sunxi's will recieve this soon after I will have some free time and figure out how to detect API change (#ifdef xorg > 1.12+ probably)

If you can fix compilation for both Linaro's 1.12 and current 1.13 yourself, we can push this to linux-sunxi's repos directly.

Best Regards,

Dmitriy Beykun

Interesting, are you sure that you have complete working xserver setup? Looks like you have libexa missing or you need to LD_PRELOAD it. 

I had mali loading with ArchLinux-ARM, but it segfault in libfb.so because I didnt fix all pScreen stuff that changed between 1.12 and 1.13.

Hi Martin,

I applied the patch and managed to build against Xorg 1.13 but I'm unable to load the driver when I attempt to start X with an unresolved symbol - exaDriverAlloc

On the development mailing lists pasting logs inline is strongly preferred for
archiving purposes, 'pastie' sites come and go, so your message will be
incomplete to someone who finds it in Google 3 years later, when that
'pastie' website is already down or has deleted/expired your pasted content.

I've completed your patch with fallbacks for old versions, hopefully, this should work for Linaro, Mer and ALARM.

https://github.com/rzk/xf86-video-mali/commit/f427d89f9683e58c952b5f6a223c9d7cc845da5e

You dont need mali drivers for CedarX output at all, I've tested Wills VLC with plain fbdev on Linaro.

Balancing the ability to be informative, concise and precise without being too verbose is a fine art, but I see your point about the ephemeral nature of pasties :)

I did manage to get the driver built and working but the instructions I attempted to follow on http://linux-sunxi.org/Mali400 page will need to be updated as they didn't quite work for me when followed to the letter.

I'll post an update on what worked for me shortly and we can decide how to best to restructure the wiki page. I'll be happy to update it once we agree.

Also, should this conversation be moved to a separate thread since I feel it got hijacked by the xorg 1.13 changes needed for the xf86-video-mali driver to compile and no longer has much to do with CedarX?

That said, I am very interested in getting CedarX working with VLC as I've been trying to build a minimal distro of Gentoo for TVHeadend with a HDHomerun Prime on the Mele A2000.

Hi,
1: I also meet with zlib,zlib.h, dbus package not found.
Copy the libz and libdbus to the arm-linux-gnueabihf toolchain lib dir
doesn't work. How can I solve it?
2: If I disable the dbus support, I meet with the
configure: error: "Could not find Cedar development headers"
./configure --host=arm-linux-gnueabihf --disable-mad --disable-postproc
--disable-a52 --disable-qt4 --disable-skins2 --disable-libgcrypt
--disable-dbus --disable-lua --enable-cedar --prefix=${PWD}/install
I have done following in libcedarx src dir:
./configure --host=arm-linux-gnueabihf --prefix=${PWD}/install
make
make install

You should use vlc instead of cvlc, cvlc use the dummy interface, no console.

I recently have gotten this installed on the Cubieboard. I'm using --fullscreen on the clv line but still seeing some desktop (video is 720P playing on a 1366x768 screen). I'm trying to integrate this into an app for a kiosk so I also want to suppress messages. Is there a command line switch that I can use that I've missed?

[George Ioakimedes]

should have mentioned that I'm using --quiet but I still see the max_analyze_duration_reached on 2 lines when the video is played.

[George Ioakimedes]

Thanks, I'll give that a try. I just wasn't sure how much of vlc was customized in this version. I'm trying to create a kiosk type application thought of perhaps using http interface of vlc.

In the wiki it states "No output modules support" would that mean http? I've tried a few cli switches and they aren't working but this is also the first time i've messed with this too.

[George Ioakimedes]

Yes, I also removed the --demux ffmeg swicth and 720P works well for me also (3.0.57 Linaro ALIP). With the --quiet still see the tag line "VLC media player 2.0.5 Twoflower.."

Daniel, I haven't tried YouTube, did you just access it with FF or Chromium? I'm curious if you did how you were able to change to using this vlc with the appropriate switches

Found a workaround using rc interface & xbindkeys (attached below if anyone is interested).

Removing the "--demux ffmpeg" allows playing YouTube (720p full screen runs smoothly), MMS working well, most formats do. All and all video hardware acceleration (with CedarX VPU and VLC) @ Linaro armhf is *working* on Allwinner A10 ( ~ Cubieboard, MK802, UHost, etc).

Thank you Wills (Dimitry and sunxi guys as well).

You can't view videos directly in the browser, but you can with VLC. 

Browsers (and any X application that hasn't been specially compiled) can't access CedarX, that leaves it with software acceleration -1fps.

Copy the link from your browser of choice and use it as VLC media-file. VLC has a built-in support for YouTube and the like (well, not really built-in, as much as I remember it's a lua script).

vlc --codec cedar --vout cedarfb --no-osd http://www.youtube.com/watch?v=yq0EmbY3XyI

As for console message try my previous post ( with </dev/null &>/dev/null & )

[Daniel Klein]

No output modules support = only direct framebuffer = only directly to your screen. You cannot decode video  using hardware processing to a window, a browser, to a different device, etc.

Seems VLC is pretty much complete and whole, it wasn't customized, but practically, in terms of features, you are limited (no GUI, no Zoom, etc, as mentioned HW accel. only through direct fullscreen rendering).

I don't know what exactly you're trying to do, but you can control VLC remotly, with your "app" (from Bash to PHP). That option is called Remote Control, RC, and you instantiate VLC as a host to receive playback commands. That's what I did with that "-I rc --rc-host=localhost:4212" switches. Hope that helps.

OK, I'm with you now. I thought perhaps you had somehow integrated this into the browser. I did try your ( with </dev/null &>/dev/null & ) trick but it still output the PID but maybe that's OK.

I just installed Apache and created a php script which calls a bash script for VLC. That works but I'm getting a problem with the audio and it not playing. I need to check the log files but I think it's something to do with permissions so it may be an Apache setup and nothing related to this VLC (although I need to check how it knew to use analog audio and not HDMI)

[Daniel Klein]

When I use /dev/null directly in the console indeed the PID is written, when I use it in a Bash script it doesn't. Another option is using Bash's "nohup", look for these options (spawning from bash), more of a linux/scripts/server general issues... 

[George Ioakimedes]

OK I am able to run from the command line and it works well. The command I use is:

linaro@linaro-alip:~$ cvlc --aout alsa --alsa-audio-device hw:0,0  --codec cedar --vout cedarfb --no-osd --fullscreen --play-and-exit Downloads/zerodarkthirty-tlr5_h720p.mov

[0x1e3b3b0] dummy interface: using the dummy interface module...

[0x1e3b7b8] main playlist: end of playlist, exiting

I can also get this to work from the command line w/o the alsa switches but I was only getting video (no audio) when I placed this command line in a script which was called from a php file running on a local Apache server. I added the alsa statements because the Apacje error log showed it couldn't open the default audio device. Here is what the log shows with the alsa switches. The video plays fine but no audio.

I'm scratching my head on this one, maybe you can see something, perhaps a permission problem of some sort??

[George Ioakimedes]

I've been testing this and so far things have gone well except the videos have always been full screen. I noticed in my FEX that both fb0_scaler_mode_enable and fb1_scaler_mode_enable are set to 0. If I enable both of these will it allow me to play the video in a borderless window that I can position on the screen? I saw that there is a width/height setting but I'm not sure of you can position the window like you can with mplayer.

It WorksForMe(tm).

Any details about the failure?

Michal

[George Ioakimedes]

I've also had success. Do a make clean and carefully watch the compile to see if any errors happen. You probably need some dependency library that isn't installed

Have a tried a file with a different format, like MP4?

Pehaps set the console layer below vlc. Supposedly the console layer
was transparent previously so only the console text would show above
vlc.

I run vlc from X and then video is shown over X.

What kernel version are you running?

Perhaps the fex file for your board configures disp differently?

I am using the cubeiboard fex file.

Thanks

Michal

[George Ioakimedes]

Yes, I must agree, this seems odd. I compiled VLC w/Cedar on a Linaro ALIP and Linaro Desktop with Kernel 3.0.57 (I think that was my kernel version) and I did not have these issues. I also was experimenting with several different display configurations with the FEX file.

Is there a reason why this couldn't be distributed as a deb package that just gets installed rather than having to compile?

I know this is a little old of a thread, but any chance someone could post this as an .APK installer package? There is a fairly new device called the Iben L1 gaming tablet, and it uses an Allwinner a31. We would love to have it, but none of us really know how to do any coding at all so we cannot get anything done. If someone could make it a general .APK for any Allwinner devices though, that would be amazing.

[Olliver Schinagl]

Most people on this list use A10/A13/A20 hardware. A31 is not really
supported due to the powerVR it has. While this is about cedarX etc,
maybe you get lucky and someone hears your call; but don't count on it
too strongly :)

Hello Wills,

I want to use your cedar plugin on android. I got a few problems. On of them BLOCK_FLAG_END_OF_STREAM, there is no define in include/vlc_block.h. Another problem is cedarfb. Can I use cedar with XCB?

Best regards

Mehmet

As mentioned at the bottom of http://linux-sunxi.org/CedarX/libve, this
code is a dead-end. To help yourself and the community you should work
on vdpau-sunxi instead.
