stream_rar.c peeks the first few bytes when trying to open, which means
that opening any stream reads at least 2KB of data (internal buffer
size) on opening. This broke --stream-dump, which saved only the data
following this initial buffer.
Hack it around by writing the current buffer to the capture file too,
and move stream_capture_write() above stream_set_capture_file() for this
purpose.
Cleaner solutions might include: handling the terrible rar thing
differently, or using the "proper" stream API for dumping. (The latter
is not done, because --stream-dump shares code with the --stream-capture
misfeature.)
Fixes#1215.
Apparently if resizing a NSWindow from a secondary thread Cocoa will
automatically protect itself using NSViewHierarchyLock and in our case,
cause a deadlock.
Fixes#1210
Although this is fine when the stream cache is active (which caches
these and returns the result immediately), it seems cleaner not to
rely on this detail.
Remove the update_cache() call from demux_thread(), because it's sort
of in the way. I forgot why it exists, and there's probably no good
reason for it to exist anyway.
It's needed for some obscure feature in combination with .rar reading.
However, it's unconditionally used by the subtitle loader code, so take
care of not blocking the main thread unnecessarily.
(Untested.)
So a client API user can know when a window is created or destroyed.
Also might be useful for the OSC: it could disable itself if video is
disabled.
Before this commit, there were only indirect ways of detecting this.
Most things should be allowed to access the client API unconditionally
(for example for sending events), so move destroying the client API
down. Also, mp_uninit_ipc() should happen before the point at which all
clients are shutdown, or there will be a small time window in which new
clients can be created after destroying them all.
Wether and when the text of a button should be squeezed when it
gets too long can now be configured in the layout:
lo.button.maxchars = <number>
nil = no squeezing (default)
If the button text has more than <maxchars> characters, it will
be squeezed to the estimated width of <maxchars>.
Doing that doesn't make sense anyway: it's meant for interactive input,
and if the output of the player is not on the terminal, how will you
interact with it?
It was also quite in the way when trying to read verbose output with
e.g. less while the player was running, because the player would grab
half of all input meant for less (simply because stdin is still
connected to the terminal).
Remove the now redundant special-casing of pipe input.
The player was supposed to exit playback if both video and audio failed
to initialize (or if one of the streams was not selected when the other
stream failed). This didn't work; for one this check was missing from
one of the failure paths. And more importantly, both checked the
current_track array incorrectly.
Fix these issues, and move the failure handling code into a common
function.

Some rationale for the documented/suggested behavior:
It's not really clear what to do with invalid UTF-8, since JSON simply
can't transport this information. Maybe you could transfer such strings
as byte arrays, but that would be very verbose and inconvenient, and
would pose the problem that it's hard to distinguish between strings
encoded in this way and actual arrays.
There are many other ways how this could be handled. For example, you
could replace invalid sequences with '?'. Or you could do it like
Python, and use certain reserved unicode codepoints to "tunnel" through
invalid bytes.
Which of these works really depends on the application. And since this
can be done entirely on the byte level (invalid UTF-8 sequences can
appear only in strings in our case), it's best to leave this to the
receiver.
Assume mpv.exe is located in $mpv_exe_dir, then config files were
preferably loaded from "$mpv_exe_dir/mpv". This was mostly traditional,
and inherited from MPlayer times.
Reverse the config path priority order, and prefer $CSIDL_APPDATA/mpv as
main config path. This also fixes behavior when writing watch_later
configs, and mpv is installed in a not-writable path.
It's possible that this will cause regressions for some users, if the
change in preference suddenly prefers stale config files (which may
happen to longer around in the appdata config dir) over the user's
proper config.
Also explicitly document the behavior.
Since the list associated with --audio-device is supposed to enable
simple user-selection, it doesn't make much sense to include overly
special things like ao_pcm or ao_null in the list. Specifically,
ao_pcm is harmful, because it will just dump all audio to a file
named audiodump.wav in the current working directory. The user can't
choose the filename (it can be customized, but not through this
option), and the working directory might be essentially random,
especially if this is used from a GUI.
Exclude "strange" entries. We reuse the fact that there's already a
simple list ordered by auto-probe priority in order to avoid having to
add an additional flag. This is also why coreaudio_exclusive was moved
above ao_null: ao_null ends auto-probing and marks the start of
"special" outputs, which don't show up on the device, but we want
coreaudio_exclusive to be selectable (I think).
Move it above ao_null, so that it can be selected during auto-probing
(even if it's only last). I see no reason why it should not be included,
and it makes the following commit slightly more elegant. (See
explanations there.)
Because Lua is so terrible, it's easy to confuse temporary values pushed
to the Lua stack with arguments if the arguments are checked after that.
Add a hack that should fix this.
The behavior of reverse cycling (with the "!reverse" magic value) was a
bit weird and acted with a "delay". This was because the command set the
value the _next_ command should use. Change this and make each command
invocation select and use the next command directly. This requires an
"uninitialized" special index in the counter, but that is no problem at
all.
Due to the way video-rotate currently works, the state will be
automatically updated once new video is decoded. So the filter chain
doesn't need to be reinitialized automatically, but there is a need to
trigger the video instant refresh code path instead.
Also move the support function closer to an annoying similar yet
different function. They probably can be unified next time major changes
are done to this code.
Allows properly changing/updating the cursor state. Useful for client
API window embedding, because the host application may not want the mpv
window to grab mouse input, and this has to manually handle the cursor.
Changing the cursor of foreign windows is usually not sane.
It might make sense to allow changing the cursor icon, but that would be
much more complicated, so I won't add it unless someone actually
requests it.
