[gst-devel] dshowvideosrc with a mux

[Andy Sturges]

I am trying to capture video and audio and mux them into a single file 
on windows XP, but am seeing very slow video capture when using any form 
of mux.  To illustrate the problem here a a couple of simple examples:

This pipeline works fine:

    gst-launch-0.10.exe dshowvideosrc ! ffmpegcolorspace  ! directdrawsink

but adding a mux/demux stage into the pipe causes the video to be very 
slow:

   dshowvideosrc ! ffmpegcolorspace ! avimux ! avidemux ! 
ffmpegcolorspace ! directdrawsink

I have tried adding queues and videorate controls but this makes no 
difference.

Any input on this problem welcome,

Andy
