When there are multiple input files, run demuxing for each input file in
a separate thread, so reading packets does not block.
This is useful for achieving low latency when reading from multiple
(possibly slow) input streams.
Its only used through the start_frame pointer and thus cannot be inlined easily.
It also appears to break compilation with some unidentified compiler on darwin.

h264: allow cropping to AVCodecContext.width/height
The above commit is not taken as is as its buggy (incorrect handling of
the interlaced case) and didnt apply cleanly.
Fixes ticket156

Override the frame size from the SPS with AVCodecContext values
if the latter specify a size smaller by less than one macroblock.
This is required for correct cropping of MOV files from Canon cameras.

With complex filters, an output can come from any input,
or several inputs, including inputs of a different type.
Copying the codec parameters from the first input with
the same type does not make any sense.
This does not change anything for simple 1->1 filters,
as source_index is set in that case.
