FLV muxer problems.

Abdullah Ali
Greetings,

I’ve been facing some trouble using the flvmux plugin in conjunction with
the avidemux element, What I’m trying to do is to encapsulate VP6 streams in
FLV files but it seems impossible.

Here are the caps I get from the avidemuxer pad:
video/x-vp6, framerate=(fraction)25/1, width=(int)320, height=(int)240

And here are the caps the flvmux video pad reports:
video/x-flash-video; video/x-flash-screen; video/x-vp6-flash;
video/x-vp6-alpha; video/x-h264

As far as I know, video/x-vp6-flash is nothing but a VP6 stream with the
image not flipped upside down.

I’ve tried to use the capssetter/capsfilter elements to rewrite/adjust the
caps and force them to connect but it did not work, although I might be
doing something wrong. I get the same result from my C++ code (gstreamermm)
and gst-launch.

Debug log output is at the bottom of this message. Any advice on the matter
is most welcome.

Regards,
Abdullah A. Hassan
