stream provides a read buffer (so even something like stream_read_char()
is very fast). This means the stream reads ahead by a few KBs, and
implies that the internal position (s->pos, which would match e.g. the
file position in stream_file.c), and the external position
(stream_tell()) can be different. stream_tell() shows how these are
related.
When dropping buffers, which happens on byte-level discontinuities with
a bunch of streams (including DVB), we should not change the position as
seen by the demuxer. On the other hand, the internal position is not
really meaningful, since these streams aren't seekable anyway. So just
change the code such that stream_drop_buffers() doesn't change the
demuxer visible position.
I'm hoping that this will fix a few problems with DVB. (Also see
previous commit.)
Document the "normal" behavior (if MPV_FORMAT_NONE is not used) first,
and then introduce MPV_FORMAT_NONE as exception.
The actual semantics didn't change in mpv; this is only clarification.
Whether you consider the semantics weird or not depends on your use
case, but I suppose it's a bit confusing anyway. At this point, we keep
MPV_EVENT_PAUSE/UNPAUSE for compatibility only.
Make the "core-idle" property somewhat more useful in this context.
bstr.start can be NULL when bstr.len is 0, so don't call memcmp or
strncasecmp if that's the case. Passing NULL to string functions is
invalid C, even when the length is 0, and it causes Windows to raise an
invalid parameter error.
Should fix#1155
For segment linking (this mechanism matches file extensions to avoid
opening files which are most likely not Matroska files in order to speed
up scanning).
Now any action that stops playback of a file (even playlist navigation)
will save the position. Normal EOF is of course excluded from this, as
well as commands that just reload the current file.
The option name is now slightly off, although you could argue what the
word "quit" means.
Fixes#1148 (or at least this is how I understood it).
This function is available starting with PulseAudio 2.0, while we only
require 1.0. This broke compilation on Ubuntu 12.04.5 LTS.
Use our own function to calculate the buffer size, which is actually
simpler and needs slightly less code.
Hopefully fixes#1154.

Run opening the stream and opening the demuxer in a separate thread.
This should remove the last code paths in which the player can normally
get blocked on network.
When the stream is opened, the player will still react to input and so
on. Commands to abort opening can also be handled properly, instead of
using some of the old hacks in input.c. The only thing the user can
really do is aborting loading by navigating the playlist or quitting.
Whether playback abort works depends on the stream implementation; with
normal network, this will depend on what libavformat (via "interrupt"
callback) does.
Some pain is caused by DVD/BD/DVB. These want to reload the demuxer
sometimes. DVB wants it in order to discard old, inactive streams.
DVD/BD for the same reason, and also for reloading stream languages
and similar metadata. This means the stream and the demuxer have to
be loaded separately.
One minor detail is that we now need to copy all global options. This
wasn't really needed before, because the options were accessed on
opening only, but since opening is now on a separate thread, this
obviously becomes a necessity.
This is the first of a series of commits that will change the Cocoa way in a
way that is easily embeddable inside parent views. To reach that point common
code must avoid referencing the parent NSWindow since that could be the host
application's window.
This is just temporary code but is a good base for future work (and baby
steps are required for these changes). The 'final destination' is embedding
the video view into any NSView but that requires some more work (the mechanism
will be the same: pass the view's pointer casted to int64_t through -wid).
For instance we will need to remove as much usage of the window instance
as possible, and use nil guards where not possible. For this reason I will
remove stuff like the mission control fullscreen feature (it's a cute feature
but annoying to support and quite limited, go make your GUIs), and a way to
lookup the current screen directly from the NSView absolute coordinates
(this is needed for ICC detection mostly, and reporting back the screen to
mpv's core).
Moreover the current view.m will need to be separated into 2 views: the actual
video view that will be embedded, and a parent view that will not be embedded
and will be responsibile for tracking events.
This could be dangerous because we initialize the window asynchronously and
return immediately from config, but since the OpenGL context is already
created, this seems to work correctly and doesn't cause weird deadlock cases.
This is for users who don't like changes. I'm hoping it will make the
process of cleaning up key bindings less bumpy.
It should be mentioned in the release notes of the next release.
It was more complicated than it had to be: the audio thread already
determines whether audio has ended, so we can use that. Remove the
separate logic for draining.
Commit 957097 attempted to use PA_STREAM_FAIL_ON_SUSPEND to make
ao_pulse exit if the stream was started suspended.
Unfortunately, PA_STREAM_FAIL_ON_SUSPEND is active even during playback.
If you pause mpv, pulseaudio will close the actual audio device after a
while (or something like this), and unpausing won't work. Instead, it
will spam "Entity killed" error messages.
Undo this change and check for suspended audio manually during init.

This doesn't look to be needed anymore. Fullscreening with both the NSView
and the NSWindow API works correctly. I guess this was forgotten in from older
code which changed presentation options directly for going fullscreen.
--x11-netwm=yes now forces NetWM fullscreen, while --x11-netwm=auto
(detect whether NetWM fullsctreen support is available) is the old
behavior and still the default.
See #888.
