streaming mpeg4 over tcp

[Kocsis Tibor]

Hi,

when I use the encoder instead of decodebin2, it's working on the client side:

gst-launch -v tcpclientsrc host=10.30.0.80 port=5000 ! multipartdemux
! ffdec_mpeg4 ! ffmpegcolorspace ! xvimagesink

Decodebin2 puts an mpegvideoparse before the decoder and that is why
it doesn't work. Maybe the multipartdemux produces too few information
when stream is mpeg4 encoded, in the sink caps there is only
"video/mpeg" without any property (parsed, systemstream or anything
else). File a bug?

Regards,
Tibor
