rtspsrc ! rtph264depay ! mp4mux not working

[Chris DeMots]

Good response. That's what I originally thought should work, but it gave the
same "failed to determine time to mux" error. I've tried so many things now,
I can't even remember them all.

Here's the stream with the h264parse in it:

gst-launch -e -vm rtspsrc
location="rtsp://axis-camera/axis-media/media.amp?videocodec=h264&streamprof
ile=test_1"
! rtph264depay byte-stream=false ! capsfilter
caps="video/x-h264,width=704,height=480,framerate=(fraction)25/1" !
h264parse ! mp4mux name=muxer ! filesink location=/tmp/test1.mp4

No idea, however I've found that sometimes it is necessary to put a parser
before the muxer.

so perhaps an h264parse or mpeg4videoparse ?
