Yes, Of course.

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

[Neal Peacock]

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 am not familiar with github.

How to fork the external office repository into github, such as vlc?

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!

Hi Wills,

  Just cloned a local copy.

  Not very familiar with libcedarx yet, just get started.

  What's you plan?

Regards,

Tim

[Tim Feng]

Hi Wills,

  Checked this out:  http://linux-sunxi.org/XBMC  , in case you have not noticed ;)

  

Regards,

Tim

[wills]

Sorry, Tim,  I'm a little busy these days, i  plan on pushing the first working version in this week.

[Tim Feng]

Awesome, can't wait to give it a try.

Regards,

Tim

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.

cheers,

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?

Regard,

Tim

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

Regards
Henrik

[Tim Feng]

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

Confusing, but no, he did not mean that cedarx ffmpeg integration is
done already.

I have pushed the first work version into github.

You must build libcedarx before vlc.

https://github.com/willswang/vlc 

https://github.com/willswang/libcedarx 

[Tim Feng]

Awesome ;) I will give it a try shortly.

Great work~

[Dmitriy B.]

Great work! Could you please document your progress and known stuff (how to compile, dependencies, bugs) at http://linux-sunxi.org/VLC ?

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.

You need run "automake -a -c" to generate configure script and  specify "--host=arm-linux-gnueabi" option to configure cross-compiling in this version.

I use ubuntu 12.04, the cross toolchains was install by "apt-get install gcc-arm-linux-gnueabi".

The following is decoder status in this version:

MPEG1/2/4 VP8 VC1 H263 XVID FLV H264 can decode

AVS/MJPEG not test

REALVIDEO not work

[Dmitriy B.]

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.
I will create the page at wiki for this info, if it is working well, I think this should eventually became default player for A10 boards. Thanks for your work!

Unfortunatelly, that doesnt work well.

http://pastebin.com/4VEwpU5v

First run was with AC_DEPLIBS_CHECK_METHOD, I've commented it out and run second time.

And this happens when I'm trying to do the standard autoreconf -vi: http://pastebin.com/a9zRRP76

Please, git clone your own repos, step-by-step do the compilation and write down your command history. Then everybody could do the same and test your work.

I have submitted autogen.sh script for generating configure file. 

[Dmitriy B.]

Thanks, libcedarx compiles now, but where in VLC tree libcedarx should be? I keep getting 

configure: error: "Could not find Cedar development headers"

I've tried to put libcedarx/ in vlc compilation directory, src/, include/ and in my /usr/include

Nothing of these make configure see the headers. (I know that this is extremely dumb question and I probably miss something obvious).

+1, I'm getting the same error message.

[wills]

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

Vlc' compiling need this header.

[wills]

The header was installed into folder specified by "--prefix" option when configuration.

Example:

./configure --host=arm-linux-gnueabi --prefix=${PWD}/install

make

make install

ls  ${PWD}/install
