fix display artifacts for RGB 8 bit input (1008 bytes, patch)
2017-06-10 11:58 UTC, Aaron Boxer 		committed Details | Review

Description Aaron Boxer 2017-06-10 11:34:28 UTC 
For grayscale, it tries to access three decoded components instead of one.
For RGB, there are artifacts when using the following pipeline:

 gst-launch-1.0 -v filesrc location=Bretagne1.jp2 ! typefind ! openjpegdec ! imagefreeze ! autovideosink
Comment 1 Aaron Boxer 2017-06-10 11:51:19 UTC 
Correction: Grayscale is fine, but RGB has artifacts on my system.
