[gst-devel] link qtdemux to h264parse

[ericcardmanNo3 <dan...@ya...>]

does anyone know how to successful link qtdemux to h264parse filter?
I demux a mp4 file with qtdemux and the resulting video stream is with
NAL,SPS,PPS. Therefore i thought i could link to h264parse and then let push
data to my decoder plugin. 

I do:
gst-launch -vvv filesrc location=r.mp4 ! qtdemux name=demux demux.video_00 !
q
ueue!video/x-h264!h264parse! decodebin !
video/x-raw-yuv,format=\(fourcc\)YV12,w
idth=320,height=240,framerate=\(fraction\)1/30 ! ffmpegcolorspace !
fbdevsink
