This is a similar filter to f_metadata, only it works on side data. Since
adding side data from a user provided arbitrary binary string is unsafe,
because current code assumes that a side data of a certain kind has the proper
size, this filter only implements selection and deletion. Also, no value
matching support is implemented yet, because there is no uniform way to specify
a side data textually.

The parser for the outdef will accept a negative value for the first
named channel's gain. As negative values effectively only invert the
phase of the signal, and not negate the level, the gains' absolute
values must be used to correctly accumulate the levels.

lavfi: set the link hwframes context before configuring the dst input
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
|

| |

| | |
The destination filter might expect the hw frames context to be already
set (this is the case e.g. for hwdownload).

As all known valid HDCD sample formats and sample rates are now handled
by the filter, remove the scan that "invades the privacy" of the filter graph
and turn off autoconvert by default as requested by Nicolas George.

I don't have any legitimate 20 or 24-bit HDCD to test. It is known
that the PM Model Two would insert packets into 20 and 24-bit output,
but I have no idea what differences in behavior existed when decoding
20 or 24-bit. For now, as with 16-bit, PE (if enabled) will expand the
top 3dB into 9dB and LLE (gain adjust) will be applied if signaled.

New versions of hdcd_scan() and hdcd_integrate() that also do the
work of hdcd_scan_stereo() and hdcd_integrate_stereo().
Some code split into previously separate functions to remove
duplication is now merged back into each function in the single
place where it is used.

The buffer is already being copied anyway, so interlace the planar
format during the copy and remove one use of auto-convert.

The PM Model Two could output HDCD-encoded audio in CD and all
DVD-Audio sample rates. (44100, 48000, 88200, 96000, 176400, and
192000 Hz)

This is the assumption that is made in pixel format conversion do
throughout the code (in particular swscale), and BT-specifications
mandate.
Add a warning to inform the user that an automatic selection is being
made.

Useful when the amerge filter parameters are generated from a script based on
the number of input streams, by allowing 1 input it does not have to be handled
specially.
The split filter also allows 1 output, so it is more consistent to allow
merging 1 input as well.
