I'm using ffmpeg to segment/concat a 120Mbit/s file in 2 second segments
to/from a HTTP server. The problem is that ffmpeg only writes/reads one
segment at a time which doesn't fully use all available bandwidth.
Each request to/from the server has a limit of 10MB/s. However using 5+

I have a sequence of video files that I captured from my video camera using
iMovie, so the output is a series of .mov files, one for each scene that iMovie
detects. The video is in mpeg2 format. I’m trying to convert each file to
h.264 in an mp4 container using the very simple:
ffmpeg -i

Hi Simon / All -
Useful to know about -nostdin - I need to spend more time rtfm.
However, update on my issue: I'm not sure where the bug lies, but I was
incorrect about stdin being the problem. It was a coincidence that
PAExec crashed near when Press [q] to stop... was output from FFmpeg.

It would have been easier if the format itself was concatenable.
What formats would you suggest?
You can probably do slightly better using
pipes.
Hm. You mean I would create a named pipe for every segment with the name =
filename?

In what way does it depend on the formats? The files are streamed to/from
in a nut container.
I've managed to fake it on the segmenting side by buffering through a file,
i.e. the segmenter writes to disk and then I wait for the segment_list
items and start uploading and then remove from disk once
