ffmpeg for QNX - does it work? Is there a repository

Supposedly ffmpeg works on QNX. Is there a repository
somewhere, or instructions for a clean build?

I need to compress video obtained from a camera
and annotated by my program. Any suggestions?

It was required to build Mplayer… Try talking to Kinners on IRC…

Is more information than this available? Is there anything
available that can compress video?

For playback - all of those are included or can be purchased. :wink:

Mplayer is audio only. What about video?

For what it’s worth, if you download the current “ffmpeg” and
configure it with

…/configure --disable-v4l --disable-dv1394 --disable-audio-oss
–disable-network --disable-ffserver --cc=qcc

it will build well enough that output_example will generate
an MPEG2 video file, which QNX’s media player will play.

John Nagle

output_example, though, generates MPEG files with some
unexpected compression artifacts. There may be a bug.

Anybody into this stuff?
