[FFmpeg-user] Mixing h263/raw files

[Shaily Athghara]

Hi,

I have a query regarding mixing/adding  h263 or raw files to a single
h263/raw file.

I perform the following command

*  ./ffmpeg -f h263 -i inv_vid/correct.h263 -i inv_vid/pending.h263 -i
inv_vid/pending1.h263 -i inv_vid/correct1.h263 -i inv_vid/pending2.h263 -f
h263 inv_vid/mix_all.h263*

But the output h263 ie mix_all.h263 only contains 34 frames (ie the first
h263 file correct.h263).I wanted to know ,Is there any command which will
mix all these h263 files and output me a single file which should contains
all the frames.

Please suggest.
Thanks,
Shaily.
