Hey folks,
My passthrough work is now at a point where I think it's good to pull to
master. All the core code for clients to signal that they are providing
a compressed format, and sinks to signal what formats they support is
there. The API is essentially the same as discussed earlier on-list,
with some small tweaks along the way as necessary.
Still pending are proper detection/signalling of available formats on
ALSA devices is to be done (Colin's looking at some of the plumbing for
S/PDIF, and HDMI ELD/EDID-based lookups are something that we need as
well), and better handling of monitors (we suspend them for now, which
works), and volumes (Tanu's got some on-going work on this).
NOTE: given the above about ALSA, topmost patch should probably not be
pulled, but is handy to have for testing.
In addition to the passthrough branch, there is a passthrough-bt branch
which has changes to the bluetooth sink to support streaming MP3 to
headsets that support it. This also needs some work before being ready
to pull.
The changes needed to actually use this in GStreamer are also done, but
not upstream yet. I need to do some rebasing to make this stuff good to
push out, so details on this in a following mail.
Comments, feedback will be very much appreciated. :)
Cheers,
Arun
