a new problem, it’s not relative to wowza server but to conversion with ffmpeg. I usually use :
ffmpeg -i file.flv -vcodec png -vframes 1 -ss 0:0:5.000 -an -f rawvideo -y snapshot.png
something which usally works fine. With the last version of wowza, there is now support for h264 so i try it and it’s really usefull. Streaming get a really better quality . But when I want to generate snapshots from those video, the command failed.

Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000
/1) -> 25.00 (25/1)
Input #0, flv, from 'file.flv':
Duration: 00:00:50.3, start: 0.000000, bitrate: 80 kb/s
Stream #0.0: Video: 0x0007, 25.00 tb(r)
Stream #0.1: Audio: mp3, 22050 Hz, stereo, 80 kb/s
picture size invalid (0x0)
Cannot allocate temp picture, check pix fmt
it seems for me that ffmpeg doesn’t support H264, this is the only thing which change since before. But surprise, the documentation and official website of ffmpeg clearly say that flv & h264 is supported. If somebody get and idea or already get this error.
