ffmpeg can not dump RTSP streaming but ffmplay can play
12 mars 2014, par pocI 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 RevoluziferI'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.aviThe 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
