Confusing Gstreamer behavior
Locked
 
|
First of all, I am a complete gstreamer beginner so begging your patience
here: *Environment*: Ubuntu 18.04, gstreamer version 1.14.5 from gst-launch-1.0 --version *Issue* 1) I'm trying to send an audio + video H264 encoded video and OPUS encoded audio in a Matroska container over RTP on localhost using rtpbin. The behavior is that I get no errors on stdout or stderr but get no video or audio. 2) Sender launch command: gst-launch-1.0 -ve rtpbin name=rtpbin \ filesrc location=../h264-video/gravity_audio_opus_video_h264.mkv ! matroskademux name=demux \ demux.video_0 ! rtph264pay ! rtpbin.send_rtp_sink_0 \ rtpbin.send_rtp_src_0 ! udpsink port=5000 \ rtpbin.send_rtcp_src_0 ! udpsink port=5001 sync=false async=false \ udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 \ demux.audio_0 ! rtpopuspay ! rtpbin.send_rtp_sink_1 \ rtpbin.send_rtp_src_1 ! udpsink port=5002 \ rtpbin.send_rtcp_src_1 ! udpsink port=5003 sync=false async=false \ udpsrc port=5007 ! rtpbin.recv_rtcp_sink_1 3) Receiver launch command: gst-launch-1.0 -ve rtpbin name=rtpbin \ udpsrc name=v_0 caps="application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264" \ port=5000 ! rtpbin.recv_rtp_sink_0 \ rtpbin. ! rtph264depay ! avdec_h264 ! autovideosink \ udpsrc port=5001 ! rtpbin.recv_rtcp_sink_0 \ rtpbin.send_rtcp_src_0 ! udpsink port=5005 sync=false async=false \ udpsrc caps="application/x-rtp,media=(string)audio,clock-rate=(int)48000,encoding-name=(string)OPUS,encoding-params=(string)2" \ port=5002 ! rtpbin.recv_rtp_sink_1 \ rtpbin. ! rtpopusdepay ! opusdec ! autoaudiosink \ udpsrc port=5003 ! rtpbin.recv_rtcp_sink_1 \ rtpbin.send_rtcp_src_1 ! udpsink port=5007 sync=false async=false 4) Results of ffprobe on the original audi/video file: ffprobe version N-95660-gfc7b6d5574 Copyright (c) 2007-2019 the FFmpeg developers built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1) configuration: --enable-cuda-nvcc --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 --enable-shared libavutil 56. 35.101 / 56. 35.101 libavcodec 58. 60.100 / 58. 60.100 libavformat 58. 34.101 / 58. 34.101 libavdevice 58. 9.100 / 58. 9.100 libavfilter 7. 66.100 / 7. 66.100 libswscale 5. 6.100 / 5. 6.100 libswresample 3. 6.100 / 3. 6.100 Input #0, matroska,webm, from '../h264-video/gravity_audio_opus_video_h264.mkv': Metadata: title : Gravity - 2K Trailer ARTIST : Warner Bros.

Hi Veela
Thanks for coming back with the solutions. On the same note, I was just wondering why aren’t you using RTSP instead? It will handle all these nuances underneath.

Hi Michael,
An excellent question. Does ignorance work as a reason? I'll check it out -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
