[gst-devel] Playing yuv/rgb files on Arm using ximagesink

[Stefan Kost]

hi,

I see two things missing. As the rgbfile has raw data, you need to specify the
bytesize of one frame in the blocksize property of filesrc. Then I would also
give a framerate and a bit-depth in the capsfilter,

gst-launch-0.10 filesrc location=/birch.rgb blocksize=57024 !
video/x-raw-rgb,width=144,height=132,depth=24,framerate='(fraction)'15/1 !
ximagesink
