Errors when streaming h264 video from gstreamer to ffmpeg
14 juin 2016, par Michael NgHi I am trying to receive a udp/rtp stream with ffmpeg in the client side but is having trouble.
Server side pipeline:
gst-launch-1.0 -v filesrc location=video2.mp4 ! decodebin ! x264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5006On the client side, I can play the video with the following pipeline:
gst-launch-1.0 -e udpsrc uri=udp://0.0.0.0:5006 ! application/x-rtp, clock-rate=90000, payload=96 ! rtph264depay ! decodebin ! autovideosinkHowever, since I want to convert the stream into a rtsp/http stream, I tried to receive the rtp stream with ffmpeg and perform something like:
ffmpeg -i udp://127.0.0.1:5006 -acodec copy -vcodec copy http://localhost:8090/feed1.ffmBut before doing that, I was testing this approach by saving the stream into a mp4 file with:
ffmpeg -f h264 -i udp://127.0.0.1:5006 -strict -2 -f mp4 stream.mp4But this did not work, it gave me the following error:
missing picture in access unit with size 15019525 [h264 @ 0x11d5100] no frame! [h264 @ 0x11f06c0] decoding for stream 0 failed [h264 @ 0x11f06c0] Could not find codec parameters for stream 0 (Video: h264): unspecified size Consider increasing the value for the 'analyzeduration' and 'probesize' options [h264 @ 0x11f06c0] Estimating duration from bitrate, this may be inaccurate udp://127.0.0.1:5006: could not find codec parameters
Have anyone tried such approach before or experienced similar problem, I would like to get some direction on how to solve it. Thanks!
