[FFmpeg-user] Converting video to MP4 through pipes

[Thierry Florac]

Hi,

I'm trying to convert a video file to MP4.
If I run "ffmpeg -i foo.mov foo.mp4", everything is OK.

But I have to use pipes to be able to include the result in
a database Blob. And when I run "ffmpeg -i foo.mov -f mp4 -", I get
several errors : 

  [mp4 @ 0xc88200] muxer does not support non seekable output
  Could not write header for output file #0 (incorrect codec
  parameters ?)

Any idea about how to solve this (without using an intermediate
temporary file, of course) ??

Regards,
Thierry
