"Blu-ray movies are playable on Linux right now, but there is no
broad support, some movies will lack audio support, and a lot of
manual intervention is required. If there is Digital Rights
Management on the Blu-ray disc, the end-user must install a utility
to dump and decrypt the high-definition files, manually input the
DRM AACS key, and take other steps to watch a legally purchased
movie. When it comes to FFmpeg support, Blu-ray discs using DTS-HD
MA for their audio format do not work. A few months back there was
some code proposed to the FFmpeg project that would partially
address this problem, but FFmpeg developers rejected the code.
Neither Diego, Baptiste, nor Robert have a Blu-ray drive, so at
this point they have no personal interest in Blu-ray support. Diego
reiterated they are interested in supporting "every format under
the Sun and thus certainly Blu-ray," but their bar to accept
patches is quite high and they will only reject patches if there
are technical issues. All three of the developers though agree that
Blu-ray support will appear in FFmpeg, but are unsure of when there
will be proper support. OpenCL & GPGPU Computing
"After talking about Blu-ray, the discussion turned to another
new standard: OpenCL. The Open Computing Language is an emerging
C99-based industry standard for parallel programming and
particularly targeting GPGPU computing. NVIDIA, ATI/AMD, and Intel
are all working on making their graphics cards and drivers
compatible with OpenCL that will transform their graphics
processors into powerful processors exposed to OpenCL code. With
GPGPU support via OpenCL, audio/video encoding could be done much
faster by leveraging a modern graphics processor. At this time,
however, they are unaware of any developers working on such
support."
