All authors have agreed.
One exception is 71247a97b3, whose author was not asked, but we deem
the change as trivial. (And technically it was replaced when the audio
chain dropped non-native endian sample formats.)
All authors have agreed to the relicensing.
The code was pretty much rewritten by Stefano Pigozzi. Since the rewrite
happened incrementally, and seems to include refactored portions of
older code, this relicensing was done on the pre-refactor code do.
The original commit adding this AO (as ao_macosx.c) credits Timothy J.
Wood as original author. He was asked and agreed to LGPL. It's not
entirely sure from which project this code came from, but it's probably
libao. In that project, Stanley Seibert made some changes to it (who as
a major developer of libao was asked just to be sure), and also Ralph
Giles and Ben Hines made two small changes. The latter were not asked,
but none of their code survived anyway.
Or maybe it would be better to write "confirm" than "change".
The MP_SELECT_LE_BE macro definition has some similarity with some old
MPlayer definition, but it's different code with a different idea, so I
don't think it's affected by that.
The BYTE_ORDER etc. macro definitions are similar to those found in
various system headers (this code emulates the ones often found in
<sys/types.h>), but I don't think there is a copyright problem either.
This didn't have a header and this was implied LGPL, but this was not
entirely correct. It turns out the printf attribute code was leaked in
from talloc, which is "LGPL v3 or later". talloc was added to the
mplayer2 code base in 27a30e310e. This remaining code was an oversight.
Since we want to reduce LGPL v3 code, replace this code with the one
from ta/ta.h. This code was explicitly written newly to get rid of
talloc and its license in 0933f12d28.
All authors have agreed to the relicensing.
iive has insisted on "LGPL v3 or later", which makes the file LGPL v3.
His commits are the following: 84ec5775089b0d8c680f. All other
contributions are LGPL v2.1. I hope we can remove these changes
completely one day to make this file LGPL v2.1.
iive also authored commit 3934b160a8, but this code is completely gone
today. (fork() and shared memory use was removed completely in favor of
threads.)
All authors have agreed, with the following exceptions:
e68d7f6858: wight wasn't asked (I think...), but even if he modified the
patch he applied, all code added by it was removed again later.
cb7768f9bb: nick could not be reached, but the declarations he added as
well as the full timer.c file were deleted again in cff81fe498 and
f800a42e45 (did it really take 6 years to remove unused declarations?).
ffaf4af230: it looks like this person wasn't contacted, but the code
added was removed again in f544bcf105.
This comes with estimated level of difficulty. Files which were already
LGPL are listed too, to avoid potential confusion.
Some entries use shell wildcards.
All authors have agreed.
Commit 94d3170bd0 is a bit murky: Nick could not be reached, and arpi's
changes were obviously inspired or copied from Nick's. However, the
changed symbols were removed and do not exist anymore.
Although pretty similar to the probably unrelicensable
video/fmt-conversion.c/h (basically using the same idea, but for audio),
it was written by someone else. The format mapping was first added in
commit ad95e046c2.
msg.c is "partial" due to "michael", whose work can be changed to LGPL
only once the core is LGPL. It's explained in the Copyright file. I
prefer to do the relicensing incrementally (due to the overwhelming
workload). Changing the license before that happens would be legally
questionable, but nothing can stop us from essentially marking it as
"will be LGPL".
All authors have agreed to LGPL, with the following exceptions:
9df11ee8bf: the author (probably) didn't agree, but the line that is
added is later fully removed.
35e90f1556: was not asked, but all iconv code was 100% removed from the
mp_msg mechanism (we alwas require UTF-8 now).
4e4f3f806e: the change by michael.
50a86fcc34: the identify variable was move, and completely removed the
latest in commit 48bd03dd91.
1f6c494641: did not agree, but due to a major mp_msg change the added
line became unnecessary and was removed.
da63498bf9: was not reachable, but the MPlayer GUI is gone from mpv
anyway (also commit fc4d6e617d removed these specific additions a long
time ago).
I guess there is a hard to balance tradeoff between appearing rude or
dismissive, and making the user think it's ok to not provide essential
information.
The author of the old code disagreed with LGPL. The new code is a clean
room reimplementation by Niklas Haas. It lacks the clamping, but we
decided it doesn't matter.
Untested, bugs can be fixed later anyway.
Until now, the texture pointer was stored in plane 1, and the texture
array index was in plane 2. Move this down to plane 0 and plane 1. This
is to align it to the new WIP D3D11 decoding API in Libav, where we
decided that there is no reason to avoid setting plane 0, and that it
would be less weird to start at plane 0.
Sigh...
The functionality is not actually needed for vdpau, but if the vdpau
hwaccel is present, the FFmpeg version is new enough that it includes
the field.
These decoders can select the decoding device with hw_device_ctx, but
don't use hw_frames_ctx (at least not in a meaningful way).
Currently unused, but intended to be used for cuvid, as soon as it hits
ffmpeg git master.
Also make the vdpau and vaapi hwaccel definition structs static, as we
have removed the old code which would have had clashing external
declarations.
Update man page for fonts.conf and subfont.ttf. These are two
undocumented features in mpv. They were only hardcoded into sub/ass_mp.c
and could not be found anywhere else in the entire codebase. Git log
reveals that fonts.conf was added in 2013 while subfont.ttf was brought
in by a ancient patch of mplayer in 2002...
These are two quite useful undocumented features when you do not want to
mess up with global fonts.conf to include more fonts.
Also document ~/.config/mpv/fonts/ directory and suggest using fonts.conf
to include additional fonts.
mpv reads all files in ~/.config/mpv/fonts/ directory into memory. If
there are a lot of fonts in that directory, mpv would use a lot of
memory. Using ~/.config/mpv/fonts.conf to include additional fonts is
more memory-efficent.
This reverts commit 142b2f23d4, and replaces it with another try. The
previous attempt removed the overlay on every rendering, because the
normal rendering path actually unrefs the mp_image. Consequently,
unmap_current_image() was completely inappropriate for removing the
overlay.
If the default shell of the user is set to csh or tcsh, the use of
"$SHELL -l -c" will fail to launch mpv because -l and -c cannot be used
together with csh or tcsh.

The new replaygain code accidentally applied the linear gain as cubic
volume level. Fix this by moving the computation of the volume scale out
of the af_volume filter.
(Still haven't verified whether the replaygain code works correctly.)
af_volume is deprecated, and so are its replaygain sub-options. To make
it possible to use replaygain without deprecated options (and of course
to make it available at all after af_volume is dropped), reintroduce
them as top-level options.
This also means that they are easily changeable at runtime by using them
as properties. Change the "volume" property to use the new update
mechanism as well.
We don't actually bother sharing the implementation between new and
deprecated mechanisms, as the deprecated one will simply be deleted.
For the from_dB() functions, we mention anders' copyright, although I'm
not sure if a mere formula is copyrightable. This will have to be
determined later.
This whole change is mostly untested. Our distributed human CI will take
care of it.
Close the audio device if there is no audio track (or stream) in the
current file. It will be opened again if the next file should contain
audio.

This drops support for the old libavcodec APIs. Now FFmpeg 3.3 or FFmpeg
git is required. Libav has no release with the new APIs yet, so for
Libav git as of a few weeks or months ago or so is required if you want
to use Libav.
Not much actually changes in hwdec_vaegl.c - some code is removed, but
the reindentation inflates the diff.
