Hi

Have managed to get it recording mp4’s…but I have to use FFMPEG (to add the AC3 audio codec and MPEG4 video codec) but it comes out worse quality v/a after this (i am unable to play it before this as the codecs are set to the Flash players, i.e. sorenson and nellymoser). I think i may need to find the way to get around this and possibly use H264.

For anybody else who wants to write files as MP4 with Wowza’s API…see the bottom of the below link:

They are written as .flv’s which take time to re-encode for VOD - can I have them record as .mp4 containers, instead? I know there is an Ondemand recording module that has that option but I specifically want to record every stream sent.

regards

craig
