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.

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.

With complex filter graphs, it can end up accessed
without having been set.

This frame rate is more reliable than the one copied
from the input stream, so it is used in priority.

The arguments now use the key=value syntax.

The current flat arguments syntax is not easily extensible
due to sws_param possibly containing commas.
This is also consistent with abuffersrc.
