AW: Dynamically record a h264 stream

[Thornton, Keith]

Hi, If you want playable files you will need a parser and a caps filter to convert to avc after the tee but before your filesink.

If I put it in front it does the same, if I put it in front and remove the h264parse before the muxer the linking fails (not sure if this is to be expected, I can remove it on the other branch, before the decoder, once I put one before the tee).

This is the caps: video/x-h264, stream-format=(string)byte-stream,
alignment=(string)au, width=(int)720, height=(int)576, framerate=(fraction)25/1, parsed=(boolean)true, profile=(string)high,
level=(string)3

The parsed=true is because it's taken with the h264parse before the tee.

How would I do that? Another thing that I didn't say is that I can record the stream just fine without the tee (but I can't watch it of course).
