0fe8acf2d6 ffmpeg: add -(no)stdin option. 
Allows to disable interaction from standard input.
Useful, for example, if ffmpeg is in the background process group.
Roughly the same result can be achieved with "ffmpeg ... < /dev/null"
but it requires a shell.

52ab418588 ffmpeg: invert using_stdin and rename accordingly. 
There are other reasons not to use stdin than having it as an input.

28f9ab7029 vp3: move idct and loop filter pointers to new vp3dsp context 
This moves all VP3-specific function pointers from dsputil to a
new vp3dsp context.  There is no reason to ever use the VP3 IDCT
where an MPEG2 IDCT is expected or vice versa.

4cfb0d871d tscc2: do not add/subtract 128 bias during DCT 
It turns out that the reference decoder subtracts 128 from DC during block
decode but adds it back during reordering block with zigzag pattern.
Transforming block with incorrect DC caused heavy visual artifacts for
many quantisers.

d483867525 avfiltergraph: document a catch in request_oldest(). 
This one is tricky. Consider a graph with two sink links, A and B.
request_oldest() requests on A, and A returns EOF. This EOF causes
a filter to flush pending frames to B; they are unrequested.
Then request_oldest() moves on to B, and B returns EOF.

1d903a5ee4 lswr: channel_map requires input conversion. 
channel_map is applied between in and postin.
Without this test, if the input format is an acceptable internal format,
the in->postin conversion is skipped. In the best case,
it ignores channel_map, in the worst case it causes an assert failure
if the number of channels is changed by the map.
