Description Nicolas Dufresne (ndufresne) 2016-07-07 21:34:24 UTC 
The following pipeline produce green frames on OSX:

  avfvideosrc ! glimagesink

The source negotiate GL memory, in UYVY with rectangle target, but apparently those texture don't work. Forcing system memory works (usign video/x-raw as filter).

What OSX version? I can't reproduce with 10.11.1
Comment 2 Matthew Waters (ystreet00) 2016-07-08 04:45:12 UTC 
I think there's some subtlety with different hardware as I've seen different results comparing a Macbook Pro and a Macbook Air.  IIRC, the MBP didn't do GLMemory correctly but the MBA did.  Unfortunately I don't have access to either piece of hardware anymore so cannot test this out.
Comment 3 Alessandro Decina 2016-07-08 05:32:05 UTC 
Could be. I have a 15" MBP with Intel HD Graphics 4000.
Comment 4 Nicolas Dufresne (ndufresne) 2016-07-08 13:19:55 UTC 
Here is an old Mac mini, but more importantly, a USB cam. I think it's 10.10 or newer, will check.
Comment 5 Matthew Waters (ystreet00) 2018-05-06 10:56:26 UTC 
This might still be valid. Needs more testing on a range of hardware.  Open/reopen a bug with more details if this issue still persists.
