Hello, I'm capturing video from a usb capture (hdmi to usb) and converting it to dash via ffmpeg and then serving it via nginx. The FFmpeg 4.3.3 command line I'm using on Raspberry Pi 3:
sudo ffmpeg -y -f v4l2 -input_format yuyv422 -video_size 1920x1080 -framerate 5 -i /dev/video0 -vcodec h264_v4l2m2m -pix_fmt yuv420p -keyint_min 30 -g 30 -map 0:v -b:v 1000k -level 41 -profile:v 77 -f dash -seg_duration 1 -streaming 1 -window_size 30 -remove_at_exit 1 -dash_segment_type 1 /dev/shm/source1/live.mpd The live.mpd produced seems to not have the correct mime for codec. See codecs= in these two examples: Got: <Representation id="0" mimeType="video/mp4" codecs="avc1" bandwidth="1000000" width="1920" height="1080" sar="1:1"> Expect: <Representation id="0" mimeType="video/mp4" codecs="avc1.420029" bandwidth="37678" width="1280" height="800" sar="1:1"> The missing part after avc1 seems to cause the browser to not play the video stream and bork with error: Cannot play media. No decoders for requested formats: video/mp4;codecs="avc1";width="1920";height="1080" Any suggestions on how to resolve this?
