16a4a18db0 af_asyncts: fix offset calculation
delta is in samples, not bytes. Also the sample format is not guaranteed
to be planar.

20a8ee3061 af_asyncts: fix compensation and PTS monotonicity
This patch improves af_asyncts behavior on streams with bogus PTS, which
are either non-monotonic, or contain PTS jitter, and trigger the
non-monotonicity error. With this patch, af_asyncts is able to correct
these streams and avoid the error.

Firstly, it fixes resample compensation calculation by supplying proper
units to avresample_set_compensation (sample count per second instead
of sample count per some arbitrary frame size). Also, the calculation of
the compensation itself is fixed - delta is proportional to an adjustment
of the compensation, not the compensation itself. Ideally, the compensation
should converge to a value that keeps delta at zero.

To be able to deal with sources with PTS jitter even without resampling,
small PTS errors are adjusted, so the output frames do not overlap.

Finally, one more monotonicity check is added.

The FATE reference changes because now there is 8 less samples of
silence because of the pts jitter.

7e350379f8 lavfi: switch to AVFrame.
Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

c143de40c3 asyncts: fix the asyncts behavior when using the first_pts option
Currently it will do padding, but it does not properly handle
start-of-stream trimming as documented.

8083332c2d asyncts: use clipped delta value when setting resample compensation
The max_comp option is supposed to limit maximum compensation, but
currently the clipped value is not actually used.

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.

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.

91a84a5247 af_asyncts: check return value from lavr when flushing.
Fixes an infinite loop on flush when avresample_get_delay() still
reports some samples but avresample_convert() doesn't return any data.

70d71b5801 af_asyncts: add first_pts option
This allows for padding/trimming at the start of stream. By default, no
assumption is made about the first frame's expected pts, so no padding or
trimming is done.

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
