Video playback problem with omx

[Abin P]

Hi all
I build  a kernal on Rcar E2(arm based board).I already installed  weston /wayland ,gststreamer-1.0 with omx(hardware acceleration enabled) in R car-E2. I checked all the omx plugins installed in Rcar E2 using  gst-inspect-1.0 omx .

Omxh264enc:openmax h.264 video decoder

Omxwmadec: openmax wma audio decoder

Omxmp3dec: openmax mp3 audio decoder

Omxaacdec: openmax aac audio decoder

Omxh265dec : openmax h.265 video decoder

Omxvc1dec : openmax wmv video decoder

Omxaaclcdec: openmax aac audio decoder

Omxmpeg4videodec : openmax mpeg4  video decoder

Omxh264dec : openmax h.264 video decoder

Then i tried to test omx hardware acceleration  using pipeline
gst-launch-1.0 -v  filesrc location=sample.mp4 ! qtdemux name=dmx dmx.video_0 ! h264parse ! omxh264dec ! waylandsink

Also checked

gst-launch-1.0 -v  filesrc location=sample.mp4 ! qtdemux name=dmx dmx.video_0 ! video/x-h264 ,width=1280,height=720,framerate=25/1  ! omxh264dec ! waylandsink

But i got plenty of errors.no video shown in display.I attached the error summary using debug
GST_DEBUG =4 gst-launch-1.0 -v  filesrc location=sample.mp4 ! qtdemux name=dmx dmx.video_0 ! h264parse ! omxh264dec ! waylandsink

Is there any issue in my pipeline?
Can anyone help me to find the real root cause of this error.

Thanks & regards
Abin

There is no pad video_00 on qtdemux here (as used in the log), it's
called video_0 as in the pipeline you pasted above.

Thanks sebastisb droge

I got a sample.h264 video.so i used pipeline like

gst-launch-1.0 -v -m filesrc  location=sample.h264 ! h264parse ! omxh264dec ! filesink= out.yuv

This pipelibe got errors like  negotiaion problem,decoder not initialized.

I used GST DEBUG = 4 to analyze the errors.Attached error status with this mail.
Please help me to find exact problem behind this.I like to make a playback using omx video decoder.
Thanks and regards
Abin

Hi 

can you try if it works with below command 

gst-launch-1.0 -v -m filesrc  location=sample.h264 ! h264parse ! omxh264dec ! videoconvert ! autovidoesink

Thanks & Regards

The problem is the following:

It looks like your OpenMAX IL is not set up correctly, and it has
problem finding some kind of file... which then makes it fail
allocating buffers (for the compressed video) on the decoder.

Dear Sebastian droge

Thanks for your valuable reply.

How can i solve the problem with allocating buffers on decoder.Is there anyway to find which file or library missing??

I am awaiting for your suggestions.

Regards
Abin

It doesn't look like a problem in GStreamer at this point, but with the
OpenMAX IL provided by your hardware's manufacturer.

You'll have to check if that is installed correctly, if you set it up
correctly in the gstomx.conf and otherwise ask them for support.

Dear Sebastian droge

I checked gstomx.conf file in build image on board.Its shows all omx packages that installed in image.How can i solve buffer allocation problem?.Here i am attaching the gstomx.conf file with this mail.

By talking to the hardware manufacturer, or having someone work on that
together with the required documentation and the hardware in question.
Without further debugging on the target hardware, this won't be
solvable.

Also you're apparently using a modified gst-omx here, it contains
changes for your hardware platform and we don't know what all these
changes are.
