Hi,
I was experimenting with the the bayer plugin, and have some
'somewhat' strange results to show...
1. gst-launch -v videotestsrc num-buffers=1 ! video/x-raw-bayer !
bayer2rgb ! ffmpegcolorspace ! ffenc_ppm ! filesink location=test.ppm
This produces a crash...
Setting pipeline to PAUSED ...
/GstPipeline:pipeline0/GstVideoTestSrc:videotestsrc0.GstPad:src: caps
= video/x-raw-bayer, width=(int)320, height=(int)240,
framerate=(fraction)30/1
Pipeline is PREROLLING ...

2. gst-launch -v videotestsrc num-buffers=1 ! video/x-raw-rgb !
ffmpegcolorspace ! ffenc_ppm ! filesink location=test.ppm
produces [1], which is okay
3. gst-launch -v videotestsrc num-buffers=1 ! video/x-raw-rgb !
rgb2bayer ! bayer2rgb ! ffmpegcolorspace ! ffenc_ppm ! filesink
location=test2.ppm
produces [2], which is somewhat strange
These tests were done on a f13 box. I'm a gst noob, so don't know how
to debug much further.
