To ensure the full range of values is still used, also adjust all uses of this function to loop from 0
instead of 1. This way only 60.00 is added and nothing lost.

-same_quant is not designed to convert between quantizer scales, AFAIK.

The list was set to avfilter_all_channel_layouts,
which is really all common channel layouts.
Not setting it leaves an empty list,
which now means really all.

According to the specification on the MSDN [1], 0 is valid for that particular field, and it should be ignored in that case.

Add request_frame() which checks the black duration when the end of the
stream is signalled. Allow to detect black video segments at the end of
the stream.

Note that the reported last black video segment duration is not very
accurate, since we still miss the duration information in the video
buffer.

Address trac ticket #1470.

It's redundant, since the input buffer is passed as a parameter to the
filter_samples() callback, and can lead to stale pointers remaining on
the link.

It will be used for audio too.

Its documentation states that it is allocated/freed by the caller, but
it is declared as an AV_OPT_TYPE_STRING AVOption. Since
36773283 the AVOptions system frees
strings automatically. This can be considered an API break, since it
won't work when the caller doesn't use av_malloc() to allocate the
memory or wants to use the string after closing the codec.

Since there is not much value in this field being an AVOption, the best
solution is to remove it from the options table.
