Hi Guys,
I have a pipleine that looks like this:
gst-launch -e v4l2src device=/dev/video0 queue-size=1 always-copy=0 !
videoscale ! videorate ! video/x-raw-yuv,framerate=30000/1001 ! \
ffmpegcolorspace ! tee name=t t. ! queue ! xvimagesink sync=false
force-aspect-ratio=true t. ! queue ! jpegenc quality=100 ! avimux ! \
filesink location=video.avi
When I type ctl-c the file ends correctly and the duration is currectly
shown on the file.
When my programme does the same thing (I'm using a modified version of
wxMediaCtrl), the duration is not properly shown (ie it shows duration = 0).
Other things like seek do not work properly either. Here is the bit of
code that is supposed to send EOS (including debag stuff).
Regards
Steve
