Comment:
VDA doesn't support decoding doesn't work with interlaced content.
This results in various crashes, hang or kernel panic.
In 2c08a7d1788b4a8183a70c288be0cec46a3f36d0, I disabled VDA playback for
interlaced content. While this is obviously a big downside as playing
content such as BBC HD will just fail on all but the most powerful mac
(mac mini 2010, macbook air 2011, entry-level MBP 13" all fail to play the
BBC HD sample when using software decode).
How VDA will behave is dependent on the graphic adapter being used.
Mark Kendall reported that it worked on his mac with a nvidia adapter (I
don't know which nvidia that is).
On my iMac with an ATI 6970M, I would only get the top half properly
decoded, the bottom half stays green.
On a 2011 macbook air with an intel HD3000, the whole picture decoded is
green.
On my mac mini 2010 with a nvidia 320M, it either hangs or cause a kernel
panic
While obviously it would be nice to play interlaced content with VDA, if
it's to get it to work only occasionally and get corrupted decoding, a
crash or worse a kernel panic most of the time: there's no other choice.
The following bug report was submitted to Apple:
The VDA framework doesn't state anything in regards to interlaced videos.
Experimentations prove that VDA doesn't handle it properly.
However, creating the decoder doesn't fail.
When trying to decode h264 interlaced video, using the VDA framework will
result in either a crash, a hang or a kernel panic.
The kernel panic can be consistently reproduced on a mac mini 2010 with a
nvidia 320M graphic adapter.
The side-effects will vary depending on which video card you are using.
ATI and Intel are more resistant to crashes.
On nvidia, it's where the worst issues can be seen.
Examples of videos causing issues:
http://dvb-antares.com/ftp/HD/BBC_H264_test6.ts
Intel: only get green crap
ATI: top half is good, bottom half is green
nVidia 320M: hang for a while. Leave the machine in unstable state, you
can't reboot it, put it to sleep. Hard reset is the only salvation.
Video sample that will cause consistently a kernel panic on nvidia 320M

Kernel panic backtrace on mac mini 2010 with 320M:
