Hi All,
I'm trying to play two video files side by side.
Here is simple working script with two videotestsrc's.
gst-launch \
videomixer name=mix \
sink_0::xpos=0 sink_0::ypos=0 sink_0::zorder=0\
sink_1::xpos=0 sink_1::ypos=0 sink_1::zorder=1\
sink_2::xpos=320 sink_2::ypos=0 sink_2::zorder=2\
! xvimagesink \
videotestsrc pattern="black" ! video/x-raw-yuv,width=640,height=180 \
! mix.sink_0 \
videotestsrc pattern=15 \
! video/x-raw-yuv,framerate=1/1,width=320,height=180 \
! mix.sink_1 \
videotestsrc pattern=11 \
! video/x-raw-yuv,framerate=1/1,width=320,height=180 \
! mix.sink_2 \
But when I'm trying to replace the second videotestsrc with video
decode pipeline, I get error:
filesrc location=video.ogv ! oggdemux ! theoradec \
! mix.sink_2
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstOggDemux:oggdemux0:
Internal data stream error.

Setting pipeline to NULL ...
Trying to play mp4 file results in slightly different error message:
filesrc location=video.mp4 \
! qtdemux ! ffdec_h264 \
! mix.sink_2\
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstQTDemux:qtdemux0:
GStreamer encountered a general stream error.
Additional debug info:

/GstPipeline:pipeline0/GstQTDemux:qtdemux0:
streaming stopped, reason not-linked
ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...
There is no errors when playing raw video or v4l2src:
filesrc location=video.raw \
! videoparse format=yuy2 framerate=1/1 width=320 height=180 \
! mix.sink_2 \
What could be the problem?
Thanks.
