ARGB or BGRA support in vmem

[jjobe]

Hi, I'm working on a video wrapper that uses libVLC, and I need to be able to decode animation codec movies that contain alpha channel. I read in this post (4 months old)

viewtopic.php?f=32&t=72059&p=238007&hilit=RV32#p238007

vmem RV32 is hard-coded to BGR_ (which is the typical X11 pixmap format). You can't output ARGB nor RGBA with VLC at the moment (the last 8 bits are garbage).

Is this still the same? Are there any plans to add support for the alpha channel (instead of having 8 bits of garbage)?

Thanks!

--vmem-chroma=chroma might help you.

You can request RGBA as output chroma from the in-memory video output. This has never been tested and will only work in that order (Red. Green, Blue, Alpha, 32-bits).

But more to the point, I do not know any existing video codec that decodes to RGBA.
