issues with connection between omx_h264dec and videomixer plugins in panda board
Locked
 
|
Hi Team,
I am trying to connect omx_h264dec ( H264 hardware accelerator decoder for panda board ) to videomixer plugin. I need to connect four RTSP streams to videomixer through hardware accelerator plugin of decoder. I am trying to play below pipeline rtspsrc location=rtsp://id:passwd@192.168.255.1:8554/uri ! rtph264depay ! h264parse access-unit=true ! omx_h264dec ! ffmpegcolorspace ! videomixer ! v4l2sink But I am not able to run this pipeline. Can anyone please help me out for the same? Thanks a lot in advance.

These are sort of new (at least with regards to gst-openmax), so AFAIK they have not been implemented there. You might want to force the caps, or hack the code to specify one or the other; your hardware might work only with bytestream for example. Also, it's usually useful to split the pipeline; say, receive the data from the payloader and save it to a file, and then try different pipelines to decode it.

Hi,
In this case omx_h264dec gives output in format of video/x-raw-yuv-strided (NV12), and ffmpegcolorspace and videomixer are not able to accept this format as an input. So I have modified this pipeline yesterday as below. sudo GST_DEBUG=2 gst-launch-0.10 rtspsrc location=rtsp://root:nlss123@192.168.1.24:554/axis-media/media.amp ! rtph264depay ! h264parse access-unit=true output-format=1 ! omx_h264dec ! "video/x-raw-yuv-strided,format=(fourcc)NV12, width=600, height=400, framerate=(fraction)30/1, rowstride=700" ! stridetransform ! "video/x-raw-yuv, format=(fourcc)NV12, width=600, height=400, framerate=(fraction)30/1" ! ffmpegcolorspace ! videomixer ! ffmpegcolorspace ! "video/x-raw-yuv,format=(fourcc)NV12, width=600, height=400, framerate=(fraction)30/1" ! stridetransform ! "video/x-raw-yuv-strided, format=(fourcc)NV12, width=600, height=400, framerate=(fraction)30/1, rowstride=700" ! v4l2sink sync=false Still I am not able to get proper output. While running the pipeline I am getting below logs in that. Can you please help me out for the same? Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ...

It seems to be supported on my system, so perhaps you need a newer version of gst-plugins-base.

Hi Felipe,
Can you please provide me details about your Gstreamer and its Base plug-in's version. It would be very much helpful in my current efforts. I am using 0.10.30 version of base plug-in. I really appreciate your help for the same. Thanks a lot in advance. Regards, Deep Shah On Thu, Apr 26, 2012 at 1:23 AM, Felipe Contreras <[hidden email]> wrote:
