gst-launch - decode - omx_h264dec - runs indefinitely producing larger output file

EZSDK version - 5_03_01_15


Compiled the gst-openmax that comes with the EZSDK and installed the files to the target fiesystem.


I was trying to run the gst-launch to decode the sample file (dm816x_1080p_demo.264) that comes with the EZSDK.

The process was running indefinitely and producing a large output file. Could you please help to know about this issue.

    Since your pipeline is trying to dump the output frames to a file, it is running pretty slow. Also the each frame output would be around 3MB, so the output file size naturally will be big. 

    Thanks

    Thanks Sathish! That answered part of the question.

    Why is it running indefinitely, until I interrupt ( by pressing CTRL + C ).

    Karthikeyan ,

    I don't think the pipeline was going to run indefinitely, from your log it shows it just finished decoding around 260 frames. If you wouldn't have interrupted it, it would have decoded all the frames and stopped. BTW why are you trying to dump the output frames, you can watch them on a display instead using a decode+display pipeline.

    Thanks,

    Satish

    Hi Sathish,

    Thanks!

    I wanted the decoded output to be stored in the file for reference, rather than displaying it.

    I interrupted the process, since the file size grew bigger. I shall test this without interrupting the decode process.

    I have an another question. The memory map is 512MB. The media controller utils/src/memsegdef_dm81xxbm_512M.c file, though named as 512M, it does not have the 512M configurations. I suppose, I need to edit it to suit the 512MB, generate the mm_dm81xxbm_512M.bin and load it through firmware_loader program. Is this right?

    Hey ,

    I'm running this gStreamer line to make capture :

    gst-launch v4l2src device="/dev/video0" always-copy=false queue-size=12 num-buffers=2000 ! 'video/x-raw-yuv-strided,format=(fourcc)NV12,width=1280,height=720,framerate=(fraction)25/1' ! omxbufferalloc numBuffers=12 ! omx_h264enc bitrate=5000000 ! gstperf ! h264parse output-format=0 ! rtph264pay ! udpsink host=192.168.16.106 port=5000

    The following line is for the receiving :

    gst-launch-0.10 udpsrc port=5000 ! 'application/x-rtp, media=(string)video, clock-rate=(int)90000, payload=(int)96' ! rtph264depay ! ffdec_h264 ! xvimagesink sync=false

    IT WORKS GREAT ON LINUX ! I check it ! .. but when i change the sync to sync=true it doesn't

    MY PROBLEM IS THAT I NEED TO RUN THE RECEIVING LINE ON WINDOWS WHICH DOESN'T WORK.

    i can see in wireshark that i got the packages with no fregmantation ..

    what should i do ? someone have any idea ?

     Hello Satish:

        Now I use ezsdk_5_04_00_11(or the older version) on DM8148,and When I use the gst-omx(and gstreamer)  command to play a Mpeg2  or H264 video ,I found the rate of playing the video was faster than the actual rate:

    example one:
    use gst-launch to play a uniticast:
    gst-launch udpsrc port=12345 ! mpegtsdemux ! video/mpeg ! mpegvideoparse ! omx_mpeg2dec ! omx_mdeiscaler name=d d.src_00 ! 'video/x-raw-yuv,width=800,height=480' ! omx_ctrl display-device=LCD ! gstperf ! omx_videosink sync=false display-device=LCD sync=false d.src_01 ! fakesink silent=true
     
    result:
           The rate of playing is not sync than the actual video rate,and is faster than the fact video.
     
    example two:
     Test the example on DM8148(H264 video file):
    gst-launch -v filesrc location=/usr/share/ti/data/videos/dm816x_1080p_demo.264 \
    ! 'video/x-h264' ! h264parse access-unit=true ! omx_h264dec ! omx_scaler \
    ! 'video/x-raw-yuv,width=800,height=480' ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 display-device=LCD \
    ! omx_videosink sync=false  top=0 left=0 display-device=LCD
     
    result:
      The rate of playing is still faster than the actual video rate(need carefully to watch ,or by comparing  with  using the omx method to play the demo or using the PC to play it)
     
    SO:
    1.Any other parameters of the plugins(parse/decoder/videosink and so on) I need to configure?
      But I have change all of them but still all the same.
    2.If I need to play the audio at the same time? or setting the sync=false?
      But I have done this,Still failed.
    3.Why will result this problem? Why the demos of the packages(dm816x_1080p_demo.264 ) still has the problem?
                     
     
     
     
    The followings was some waring infor when use the omx_h264dec plugin:
    Stream is corrupt error, ignorable ...

    Hello Zhichao,

    You could check here for examples:

    http://processors.wiki.ti.com/index.php/DM81xx_Gstreamer_Pipelines

    result:
      The rate of playing is still faster than the actual video rate:
      >> You should change omx_videosink sync=false to omx_videosink sync=true
    Best Regards
