I am interested in getting in touch with people who could help me with the
following question: what is the minimal subset of features necessary for vdr
(or mplayer)?
In regard of OGP? Just a framebuffer. Everything else can be done
in software.
This has been discussed before. CPUs aren't fast enough (see the archives
for examples). Therefore we MUST have some sort of hardware assist.
And i clearly vote against it. OGD1 wont have enough
real estate to implement a full MPEG2 decoder
OGD1 is one thing, but OGC needs mpeg decoding or why bother?
We already have hw that can't do video, don't need another.
And even though modern ATI and nvidia cards support
a quite large subset of what is needed to decode
MPEG2/MPEG4/h.264 hardly anyone uses it.
There is no way to use the ATI hw features. Nvidia can only
be used with a binary-only driver that is extremely buggy, has
security holes, and causes data loss. Remember the point of
OGP? To make a graphics/video chip that you can actually use.
Undocumented hw features aren't very useful.
Documented hw that doesn't do what you need isn't very useful.
We need both the feature and the documentation.
I still think that the most efficient way to add MPEG (and other)
decoding is to add a DSP to the card. They *are* fast enough to do it.
