we tend to maintain the TI PPA so that h/w accelerated video playback
works, at least most of the time... it would be easier if you could
provide details on how you install 12.04 + PPA on your panda, as well
as some logs. the interesting log files for us to help are:

# dmesg
# cat /var/log/Xorg.0.log
# lsmod
# dpkg -l
# cat /sys/debug/kernel/remoteproc/*/traces

if you can get something like this too:

GST_DEBUG=*:5 gst-launch playbin2 uri=file://<path to file>

then we should be able to quickly identify the problem..

also, if you want to check if h/w video is being used, you can monitor
/proc/interupts and check if MAILBOX interrupts count increase
(alternatively you can use 'itop' for monitoring). there is 1
interrupt per frame decoded if everything works well.

remove the vram= and two mem= in the bootargs, and then regenerate
boot.src (mkimage or flash-kernel)

Dear Wubin,

Since you have installed the TI ppa update, please change the bootargs in boot.script as shown below:

fatload mmc 0:1 0x80000000 uImage

fatload mmc 0:1 0x81600000 uInitrd

setenv bootargs ro elevator=noop console=ttyO2,115200n8 mem=1G@0x80000000 root=/dev/mmcblk0p2 fixrtc splash

bootm 0x80000000 0x81600000

Then re-generate the boot.scr file as pointed out by Rob.

Cheers,

Jayneil.

Besides, after installing the newest TI release PPA on new Ubuntu system, the kernel becomes very fragile. It either crashes during booting, or freezes anytime, especially when the CPU load is high. I need to reboot many times in other to start the system. Someone said that there is something wrong with CPU frequency, but his trick did not work on me. I will appreciate if you can also check the "kernel.oops.log" from the kernel error.

Thanks.

Thanks rob and Jayneil,

Finally I am able to see the h264 video clips working with totem by hardware acceleration. I would suggest to add this part to the PPA installation manual as well.

Here I have several questions, I will appreciate if you would give some advise for them.

(1) I see some minor tearing from the video, especially when the motion in the video is moving fast. Is it fixable?

(2) I see some "leftover" image from the video if I try to resize the video playing window or switch among several windows. Is it fixable?

(3) Is there a way to make the chromium browser work with the ducati decoder? I understand chromium/chrome browser uses ffmpeg framework instead of gstreamer, but it would be great if there is any trick to make the hardware decoder work with ffmpeg.

Thanks.
