Just curious - can ffserver potentially be used as an alternative to Wowza and
Adobe FMS for http live streaming?
I'm afraid I've never completely understood the differentiation between ffmpeg
and ffserver.

Does anyone know why dca is using this deprecated function instead of
request_channel_layout? I changed it over here and it seems to work fine, I
converted dts to flac and experienced no problems at all but I thought I'd
ask just to be sure.

Hi,
I am using the libav* libraries from FFMPEG to produce a MPEG2 video in
MPEG2-TS stream.
I discovered that the usage of some options are changing dramatically the CPU
used to encode a frame :

That's right, I ran the gdb on ffplay.exe instead of ffplay_g.exe

So I re-ran it on ffplay_g, and the bt command of gdb gives me the

To the best of my knowledge this has known security
issues including known sample exploits.
Note that it is also missing thousands of features
present in current versions of FFmpeg.

Thanks a lot! As pointed out the problem was the incorrect placing of

Dear all,
I built a custom version of ffmpeg on msys/mingw32. ffmpeg and ffprobe are
behaving very well, but ffplay crashes when reading any file with video. It
displays the first image of the video and then exits without error messages.
Did anyone encountered and solved this issue ?
