I got a small m4v file (Xvid;
http://www.multiupload.com/S9CJO31ED4]small.m4v) and I want to mux into an
.avi container.
ffmpeg reports it as:
Stream #0:0: Video: mpeg4 (Advanced Simple Profile), yuv420p, 720x576 [SAR
64:45 DAR 16:9], 25 fps, 25 tbr, 1200k tbn, 25 tbc
Problem is when I remux it with:
ffmpeg -y -i "D:\Encoding Output\small.m4v" -vtag xvid -vcodec copy -map
0:0 -f avi "D:\Encoding Output\small.avi"
ffmpeg reports:
Input #0, m4v, from 'D:\Encoding Output\small.m4v':
Duration: N/A, bitrate: N/A
Stream #0:0: Video: mpeg4 (Advanced Simple Profile), yuv420p, 720x576
[SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 1200k tbn, 25 tbc
Output #0, avi, to 'D:\Encoding Output\small.avi':
Metadata:
ISFT : Lavf53.29.100
Stream #0:0: Video: mpeg4 (xvid / 0x64697678), yuv420p, 720x576 [SAR
64:45 DAR 16:9], q=2-31, 25 fps, 50 tbn, 50 tbc
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Press [q] to stop, [?] for help
frame= 664 fps= 0 q=-1.0 Lsize= 2195kB time=00:00:26.54 bitrate=
677.5kbits/s
video:2158kB audio:0kB global headers:0kB muxing overhead 1.718484%
and the resulting container fps flag is set to 50fps, not 25 fps;
even when I use:
ffmpeg -y -r 25 -i "D:\Encoding Output\small.m4v" -vtag xvid -vcodec copy
-map 0:0 -r 25 -f avi "D:\Encoding Output\small.avi"
I still end up with 50fps in the container,... :/
