no yuv output
gst-launch-1.0 filesrc location=gdr.m300.h264 ! h264parse ! nvv4l2decoder ! fakesink dump=true
change nvv4l2decoder to avdec_h264, then yuv output

Hi,
Please attach the h264 stream so that we can do further investigation, and share the release version( $ head -1 /etc/nv_tegra_release ) you are using.

Hi,
The stream looks invalid. Try to decode it with ffmpeg and fails.

Looks like it contains many invalid SEIs and no valid video frame(s).

Try again with this option: ffmpeg -flags2 showall -i gdr.m300.h264 a.yuv

DaneLLL · September 18, 2020, 1:51am

Hi,
We can get valid YUV file by adding -flags2 showall. Could you give more information about the option? We don’t know much about it and more information shoud be helpful. Thanks.

hexulei · September 18, 2020, 2:18am

Forget ffmpeg. Just use /usr/src/jetson_multimedia_api/samples/00_video_decode.

cannot display: ./video_decode H264 gdr.m300.h264
can display: ./video_decode H264 –report-input-metadata gdr.m300.h264
- ctx.dec->enableMetadataReporting(); in video_decode_main.cpp
  - control.id = V4L2_CID_MPEG_VIDEO_ERROR_REPORTING; in NvVideoDecoder.cpp
  - CHECK_V4L2_RETURN(setExtControls(ctrls), in NvVideoDecoder.cpp
    - v4l2_ioctl(fd, VIDIOC_S_EXT_CTRLS, &ctl); in NvV4l2Element.cpp

Hi,
Since ffmpeg is reference software decoder. Would be great to understand more about how it works and then check the hardware decoder. Are you able to help on this?

hexulei · September 18, 2020, 6:07am

I use this cmd to convert H264 to MP4: ffmpeg -flags2 showall -i gdr.m300.h264 output.mp4.
The option means “Show all frames before the first keyframe”.
My ffmpeg version is 4.3.1 for Windows or 3.4.8-0ubuntu0.2 for Ubuntu:18.04.

DaneLLL · September 24, 2020, 9:18am

Hi,
Looks like reference frame number is not correct in the h264 stream. We will check further and update. The quick solution looks fine. You may use it for this sort of h264 stream.

DaneLLL · October 16, 2020, 3:20am

Hi,
We have checked and confirmed it is obligatory to enable error report in decoding H264/H265 GDR streams. So it is expected that we have to set –report-input-metadata in running 00_video_decoder and set enable-frame-type-reporting=true to nvv4l2decoder.
