b90210e9c5 doc/filters: clarify use of graph2dot
The GRAPH_DESCRIPTION string supplied to graph2dot must include explicitly
defined inputs and outputs which are not normally part of the command line
used in a real invocation.

This clarifies that requirement, and provides an example.

54ca7e39da lavfi/hue: add process_command callback
This allows dynamic reconfiguration of the filter.
The callback uses some code that was in the init function. Hence this code
has been moved in its own function.

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.

4ce87ecf2a asrc_flite: do not crash on multiple instances.
The voice register functions return the same voice structure
upon multiple registration. It causes us two problems:

If we delete a voice without deregistering it, it leaves
a dangling pointer inside the library.

If we delete or unregister a voice at uninit, it may still
be in use by another instance of the filter.

The second problem is solved by keeping an usage counter inside
asrc_flite. This is not thread-safe, but neither is flite itself.

82ecae8a70 lavfi: add alphaextract and alphamerge filters
These filters are designed for storing and transmitting video sequences
with alpha using higher-efficiency codecs such as x264 which don't
natively support an alpha channel. 'alphaextract' takes an input stream
with an alpha channel and returns a video containing just the alpha
component as a grayscale value; 'alphamerge' takes an RGB or YUV stream
and adds an alpha channel recovered from a second grayscale stream.
