• FFMPEG frame counter hangs and stop streaming

  18 janvier 2021, par user2821178

  Good morning,

  


  I use a Raspberry, linked to an IP cam, in order to send the streaming to my Facebook Page.

  


  All works good, but it happen, that for some reason facebook stops to receive the streaming, but FFMPEG continues to works.

  


  I've noticed that even if FFMPEG seems to work correctly, the frame counter stops.

  


  This is the command :

  


      RTSP_URL="rtsp://xxxxxxxxxxx/videoMain";
YOUTUBE_URL="rtmps://live-api-s.facebook.com:443/rtmp/";
YOUTUBE_KEY="zzzzzzzzzxxxxxxxxyyyyyyyyyy";
LOGO="-i yyyyyyyyyyy.png -filter_complex overlay=x=1:y=(main_h-overlay_h)";
VIDEO="-s 512:288 -c:v libx264 -x264-params nal-hrd=cbr -b:v 150k -minrate 50k -maxrate 150k -bufsize 300k";
AUDIO="-c:a aac -strict experimental";
KEYFRAME="-g 100";
OUTPUTFORMAT="-f flv";

COMMAND="sudo ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -stimeout 5000000 -i ${RTSP_URL} ${LOGO} ${VIDEO} ${AUDIO} ${KEYFRAME} ${OUTPUTFORMAT} ${YOUTUBE_URL}/${YOUTUBE_KEY}";

$COMMAND > streamOut.txt 2>&1;


  


  Here an extract of the output :

  There is a way to stops FFMPEG when this happen ?

• FFMPEG keeping quality when reducing FPS and streaming over RTSP with rtsp-simple-server

  25 janvier 2021, par Jens Schneider

  I'm using the rtsp-simple-server (https://github.com/aler9/rtsp-simple-server) and feed the RTSP Server with a FFMPEG stream.

  


  I use a docker compose file to start the stream :

  


  version: "3.8"

services:

  ffmpeg:
    container_name: ffmpeg-base
    restart: always
    image: "jenssgb/rtspffmpeg:base"
    depends_on:
      - rtsp-server
    volumes:
      - $PWD/:/video
    network_mode: "host"
    command: "ffmpeg -re -stream_loop -1 -i /video/footage-1-b.mp4 -c copy -f rtsp rtsp://localhost:8554/compose-rtsp"
  
  rtsp-server:
    container_name: rtsp-server-base
    restart: always
    image: "aler9/rtsp-simple-server"
    network_mode: "host"


  


  Now I'm trying to reduce the FPS of my video with transcoding it :

  


  command: -re -stream_loop -1 -i ${VIDEO_FILE} -vf "fps=${FPS_COMPOSE}" -f rtsp rtsp://localhost:8554/compose-rtsp


  


  This is basically working, but the quality of the output video becomes pretty bad. I tried a lot of things like -c:v libx264 which did help for a minute but let ffmpeg crash then.

  


  av_interleaved_write_frame(): Broken pipe0:00:09.99 bitrate=N/A speed=0.985x    
[rtsp @ 0x5563b1755640] Packets poorly interleaved, failed to avoid negative timestamp -33660 in stream 0.
Try -max_interleave_delta 0 as a possible workaround.
av_interleaved_write_frame(): Broken pipe
Error writing trailer of rtsp://localhost:8554/compose-rtsp: Broken pipe


  


  Any idea how I can reduce the FPS send the stream to the server but keep the video quality ? Later I'm going to reduce the resolution as well - but for now I want to keep resolution and quality but only reduce the FPS.

  


  Full logs from my test with -c:v libx264 :

  


      ffmpeg -re -stream_loop -1 -i footage-1-b.mp4 -vf "fps=5" -c:v libx264 -f rtsp rtsp://localhost:8554/compose-rtsp

• Overlaying a transparent webm on an MP4 freezes at the start sometimes

  23 janvier 2021, par joshlat94

  I'm currently using the command
 ffmpeg -i mainvideo.mp4 -vcodec libvpx -i myoverlay.webm -filter_complex "overlay = 5:5" done.mp4
To overlay a transparent webm on top of my main mp4. But for some reason the output video is frozen for the first 1 second but the audio is completely fine.

  


  I've tried this command with other videos and it works sometimes but most of the time the first few frames seem frozen

  


  Edit.
I have two main mp4 files, broken_source.mp4 and working_source.mp4. Putting the overlay on broken_source results in the output having the first 1 second of video frozen (audio completely fine) but putting the same overlay on working_source.mp4 is perfect and has no issues

  


  Logs for putting the overlay on working_source :

  


  ffmpeg -i working_source.mp4 -vcodec libvpx -i chat.webm -filter_complex "overlay = 0:0" working_complete.mp4
