• ffmpeg can not dump RTSP streaming but ffmplay can play

  12 mars 2014, par poc

  I want to dump the RTSP streaming into a file.

  ffmpeg -y-i rtsp://172.19.12.37/live.sdp -acodec copy -vcodec copy tmp.mp4

  But I got errors,

  [mp4 @ 0x7fe98400dc00] track 1: could not find tag, codec not currently supported in container

  Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

  However, I can play the RTSP streaming by any media player, what was wrong with my ffmpeg command ?

  Is there any options can dump any stream and dump it into identical video format.

• FFMPEG result video freezes in the middle of playback

  10 mai 2013, par Revoluzifer

  I'm trying stitch four source videos together into one grid. For testing purposes I'm working with a single source flv using this command :

  ffmpeg -i woohoo.flv -i woohoo.flv -i woohoo.flv -i woohoo.flv \
  
  -filter_complex "[0:0]pad=iw:ih[a];[1:0]scale=w=iw/2:h=ih/2[b];
  
  [2:0]scale=w=iw/2:h=ih/2[c];[3:0]scale=w=iw/2:h=ih/2[d];
  
  [0:0]scale=w=iw/2:h=ih/2[e];[a][b]overlay=w[x];[x][c]overlay=0:h[y];
  
  [y][d]overlay=w:h[z];[z][e]overlay=0:0" -qscale 1 stitched.avi

  The stitching itself is working great, but somehow the resulting video does not show as expected.
  After running for a few frames, it gets stuck at a single frame for most of the video, skipping the frames which should be there.

  While encoding ffmpeg throws a freaking lot of messages like :

  [Parsed_overlay_8 @ 000000000459e080] Buffer queue overflow, dropping.

  Any hints on how to solve my problem ?
  My source flv is h.264 encoded, coming from Red5 media server.

  Edit : Output is :

  root@s15757871:/opt/red5/webapps/woohoo/streams# ffmpeg -i out_3.mp4 -i 3.mp4 -filter_complex "[0:0]pad=iw:ih[a];[1:0]scale=w=iw/2:h=ih/2[b];[a][b]overlay=w:h" -vcodec libx264 -r 30 -acodec copy out_final.mp4
