opengl interops: signify the interop is outputting RGBA/BGRA
The vlc_gl_tex_cfg
format is GL_RGBA
or GL_BGRA
.
We have to set a new chroma otherwise it would use the input format of the interop in the sampler. In that code it only matters if this is a YUV chroma (and what kind of YUV). Otherwise any RGB chroma will be correct. It's better to provide a hint of what kind of RGB we're providing, VLC_CODEC_RGB32
being the worst.
