94eadc8ba0 SDL does not seem to support more than two channels. 
So, if this is the case, ask for downmixing by the codec.

2886f3113e Notify the input coder about the number of requested channels. 
If the decoder does not fulfill our request, try using lavf's audio_resample().
If that also fails, bail out.

9a1feb8608 Fix brain-dead parts of r11216, specifically: 
Actually unreference removed pics
And check for too many reference frames as originally intended, not equal
to max reference frames.

aeb59e839f Ensure that our total reference frame count does not exceed the SPS 
max frame count, which is limited to less than the size of the
reference buffers, thereby preventing overflow.

41f7e2d11d Actually return with an error condition if we're being asked to deal with too 
many reference frames. Also check max num ref frames against our internal
ref buffer sizes.

33e0073129 Make h264 decoder conform to requirements of mpegvideo's MPV_frame_start. 
Namely, that it should not be called if you are starting to decode a B
frame without any reference pictures.
Prevents an endless allocation cycle in MPV_frame_start that will end in
picture buffer overflow and abort.
Fixes roundup issue 216.
