Log of crash

Using gst-play-1.0 on OSX, I get the following error:

0:00:00.205942000 51423 0x7fbd860585e0 ERROR              glslstage gstglslstage.c:467:_compile_shader:<glslstage1> fragment shader compilation failed:ERROR: 0:45: Use of undeclared identifier 'gl_FragColor'

This can be reproduced by playing the file using gst-play-1.0 available at https://www.dropbox.com/s/3x199rdah1x4ohg/claudia_aac.mov?dl=1

Attached is a debug log of gl*:6 playing that file.

Thanks!

Note I couldn't actually reproduce this on my Intel hardware and switching to my nvidia card is a hassle so this is actually untested but it should work ;)

    glcolorconvert: mangle gl_FragColor for GL3
    
    Some drivers don't provide the compatibility definition and we need to provide
    our own 'out vec4' variable to put the results of the fragment shader into.
