6b15874fc2 af_resample: do not touch the timestamps if we are not resampling
This filter currently assumes that the input audio is continuous and
does some timestamps manipulation based on this assumption.

This is unnecessary if we are only converting the channel layout or the
sample format, without resampling. In such a case, just leave the
timestamps as they are.

Otherwise trailing zeroes would appear.

6cbbf0592f resample: Avoid off-by-1 errors in PTS calcs.
The rounding used in the PTS calculations in filter_frame() does
not actually match the number of samples output by the resampler.
This leads to off-by-1 errors in the timestamps indicating gaps and
underruns, even when the input timestamps are all contiguous.

565e4993c6 lavfi: merge start_frame/draw_slice/end_frame
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

568c70e79e lavfi: convert input/ouput list compound literals to named objects
A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

7b556be673 af_resample: avoid conversion of identical sample formats for 1 channel
When there is only 1 channel, the planar and interleaved formats of the same

e7ba5b1de0 lavr: change the type of the data buffers to uint8_t**.
This is more consistent with what the rest of Libav does.

This breaks API.
