Move the update_avsync_before_frame() call further down. Moving it
closer to where the time_frame value is used (and which the function
updates) should make the code more readable. With this change, there's
no need anymore to reset the time_frame value on the video reconfig
path.
Move the update_avsync_after_frame() up. Now no meaningful amount of
time passes since the previous get_relative_time() call anymore, and the
second one can be removed.
Now it shows one of:
- "Subtitles hidden" (sub-visibility=no)
- "Subtitles visible" (sub-visibility=yes, sub!=no)
- "Subtitles visible (but no subtitles selected)" (otherwise)
It should be a bit more self-explanatory than before. On the other hand,
I have no clue about UI issues.
This also gets close to what's reasonably possible with the OSD
expansion string syntax, which is why it looks so awful.
...into its own functions. The central playloop function is still too
big, but looks much cleaner now.
No changes in functionality. The code moved to handle_playback_restart()
is unindented by 1 level and moving it out of the if condition around.
The if condition is inverted and early-exits from the function. Also
some comments are changed.
mpctx->audio_delay always has the same value as opts->audio_delay. (This
was not the case a long time ago, when the audio-delay property didn't
actually write to opts->audio_delay. I think.)
This allows seeking audio between two video frames that are relatively
far away.
The implementation of this is a bit subtle. It pretend the audio
position is different, and the actual PTS adjustment happens in audio.c
with this line:
sync_pts -= mpctx->audio_delay - mpctx->delay;
Effectively this is the same as setting sync_pts to hrseek_pts after
this line, though. (I'm actually not sure if this could be written in a
more straightforward way; probably yes.)
Some files can have audio after video has ended, and playback of the
audio-only remainder is supposed to work just fine.
Seeking is broken-ish though. Not much can be done about this, since
it's the way demuxers work. Also, such files are obscure corner cases.
But enabling hr-seek for audio after video end can improve the situation
a lot.
This helps with issue #1533. The reported also provided a command line
to produce such a file:
ffmpeg -i image.jpg -i audio.flac -threads $(nproc) \
-c:v libvpx -crf 10 -qmin 5 -qmax 55 \
-vf scale=360:-1 -sws_flags lanczos -c:a libvorbis -ac 2 \
-b:a 128K out.webm
If a file is unseekable (consider e.g. a http server without resume
functionality), but the stream cache is active, the player will enable
seeking anyway. Until know, client API user couldn't know that this
happens, and it has implications on how well seeking will work. So add a
property which exports whether this situation applies.
Fixes#1522.
This was subtly broken by commit a937ba20. Instead of framestepping over
the timeline segment boundary, it would just unpause playback, because
seeking now resets mpctx->step_frames. This was especially apparent when
doing something like "mpv *.jpg --merge-files".
Fix by restoring the step_frames field specifically if the seek is done
for switching segment boundaries. Hopefully the number fields which need
such an exception on seeking won't grow and turn this code into a mess.
Make the default value part of the option metadata, instead of doing
this in the screenshot code. Makes more sense with --list-options and
the command.c option metadata properties.
At the time screenshot support was added, images weren't refcounted yet,
so screenshots required specialized implementations in the VOs. But now
we can handle these things much simpler. Also see commit 5bb24980.
If there are VOs in the future which can't do this (e.g. they need to
write to the image passed to vo_driver->draw_image), this still could be
disabled on a per-VO basis etc., so we lose no potential performance
advantages.
For some sites, youtube-dl sends a special user-agent. If we don't send
the same user-agent, the server will reject mpv's connection attempt.
This was observed with trailers.apple.com. Fix it by forcing the
user-agent youtube-dl uses.
Some sites set cookies when doing a website access, and require the
client to provide these cookies when downloading the actual media. This
is needed at least by nicovideo.jp. Fix by adding youtube-dl's cookies
to our request headers.
Both of these require a very recent youtube-dl version (youtube-dl added
the necessary headers a few hours ago). The script still works with
older youtube-dl versions, though.
Use different VOCTRLs for "window" and normal screenshot modes. The
normal one will probably be removed, and replaced by generic code in
vo.c, and this commit is preparation for this. (Doing it the other way
around would be slightly simpler, but I haven't decided yet about the
second one, and touching every VO is needed anyway in order to remove
the unneeded crap. E.g. has_osd has been unused for a long time.)
New command `mouse <x> <y> [<button> [single|double]]` is introduced.
This will update mouse position with given coordinate (`<x>`, `<y>`),
and additionally, send single-click or double-click event if `<button>`
is given.
Repurpose demuxer->filetype for this. It used to be used to print a
human readable format description; change it to a symbolic format name
and export it as property.
Unfortunately, libavformat has its own weird conventions, which are
reflected through the new property, e.g. the .mp4 case mentioned in the
manpage.
Fixes#1504.
`core-idle` depends on seeking state `mpctx->restart_complete`,
so make `core-idle` notified whenever `seeking` is notified, too.
`paused-for-cache` can be changed on MPV_EVENT_CACHE_UPDATE obviously.
Finally, `MPV_EVENT_PLAYBACK_RESTART` should be notified after
`mpctx->restart_complete` changed.
Instead of converting the hw surface to an image in the VO, provide a
generic way to convet hw surfaces, and use this in the screenshot code.
It's all relatively straightforward, except vdpau is being terrible. It
needs a huge chunk of new code, because copying back is not simple.
Sigh...
The C locale system is incredibly shitty, and if used, breaks basic
string functions. The locale can change the decimal mark from "." to
",", which affects conversion between floats and strings: snprintf() and
strtod() respect the locale decimal mark, and change behavior. (What's
even better, the behavior of these functions can change asynchronously,
if setlocale() is called after threads were started.)
So just check the locale in the client API, and refuse to work if it's
wrong. This also makes the lib print to stderr, which I consider the
lesser evil in this specific situation.
This function is always available, which is reflected by the fact that
the configure check doesn't actually bother to check for its existence.
Instead, MinGW and Cygwin imply it. The check was probably "needed" when
the priority code was still in a separate source file.
Remove the check, and use _WIN32 for testing for the win32 API (in a
bunch of other places too).
Pass through the seek flags to the stream layer. The STREAM_CTRL
semantics become a bit awkward, but that's still the least awkward
part about optical disc media.
Make demux_disc.c request relative seeks. Now the player will use
relative seeks if the user sends relative seek commands, and the
demuxer announces it wants these by setting rel_seeks to true. This
change probably changes seek behavior for dvd, dvdnav, bluray, cdda,
and possibly makes seeking useless if the demuxer-cache is set to
a high value.
Will be used in the next commit. (Split to make reverting the next
commit easier.)
Before this, we merely printed a message to the terminal. Now the API
user can determine this properly. This might be important for API users
which somehow maintain complex state, which all has to be invalidated if
(state-changing) events are missing due to an overflow.
This also forces the client API user to empty the event queue, which is
good, because otherwise the event queue would reach the "filled up"
state immediately again due to further asynchronous events being added
to the queue.
Also add some minor improvements to mpv_wait_event() documentation, and
some other minor cosmetic changes.
We still need to send the VO a duration in these cases. Disabling
framedrop has logically absolutely nothing to do with these cases; it
was overlooked in commit 918b06c4.
So we always send the frame duration (or a guess for it), and check
whether framedropping is actually enabled in the VO code. (It would
be cleaner to send framedrop as a flag, but I don't care about that
right now.)
The "ontop" and "border" properties already used a common
mp_property_vo_flag() function, and the corresponding VOCTRLs used the
same conventions. "fullscreen" is pretty similar, but was handled
slightly similar. Change how VOCTRL_FULLSCREEN behaves, and use the same
helper function for "fullscreen" as the other flags.
This is for the ordered chapters case only. In theory this could have
resulted in initial audio, video or subs missing, although it didn't
happen in practice (because no streams were selected, thus the demuxer
thread didn't actually try to read anything). It's still better to make
this explicit.
Also, timeline_set_part() can be private to loadfile.c.
The last video frame is another case that has a separate code path,
although it's pretty similar to the one in commit 73e5aa87. Fix this
in a different way, which also takes care of the last frame case,
although without context the code becomes slightly more tricky.
As further cleanup, move the decision about framedropping itself to
the same place, so the check in vo.c becomes much simpler. The check
for the vo->driver->encode flag, which is remvoed completely, was
redundant too.
Fixes#1480.
If the video format changes (e.g. different frame size), a special code
path is entered to wait until the currently displayed frame is done.
Otherwise, the frame before the change would be destroyed by the
vo_reconfig() call.
This code path didn't respect --untimed; correct this.
Fixes#1475.
This was forgotten when the option was implemented, and makes this
option work as advertised.
Fixes#1473 (though the default behavior is probably still stupid).
Upon the "DEL" key binding or the "disable-osc" message, the OSC should
stay permanently invisible. This was recently broken (not sure by what),
because other code accidentally reenables it anyway, which resulted in
the OSC appearing again when moving the mouse.
The percent-pos property normally goes by time, except for file formats
like .ts or .ogg, where you can't trust the timestamps and duration info
to compute the position in the overall files. These use the byte
position and size instead.
When the file position was unavailable (e.g. due to an ongoing seek),
the percent-pos was unknown. Change it to use the time position instead.
In most cases, it's actually accurate enough, and the temporary
unavailability of the property can be annoying, e.g. on the terminal
status line.
mpv needs at least an audio or video track to play something. If the
track selection is basically insufficient, the player will immediately
skip to the next file (or quit).
One slightly annoying thing might be that trying to play a subtitle file
will close the VO window, and then go to the next file immediately (so
"mpv 1.mkv 2.srt 3.mkv" would flash the video window when 2.srt is
skipped). Move the check to before the video window is possibly closed.
This is a minor cosmetic issue; one can use --force-window to avoid
closing the video window at all.
Fixes#1459.
We now use threads and other pthread API a lot, and not always we use it
from threads created with pthread_create() (or the main thread). As I
understand, with static linking we would have to use
pthread_win32_thread_attach/detach_np() every time we enter or leave a
foreign thread. We don't do this, and it's not feasible either, so it's
just broken.
This still should work with dynamic pthreads-win32. The MinGW pthread
implementation should be unaffected from all of this.
Make their meaning more exact, and don't pretend that there's a
reasonable definition for "bits-per-pixel". Also make unset fields
unavailable.
average_depth still might be inconsistent: for example, 10 bit 4:2:0 is
identified as 24 bits, but RGB 4:4:4 as 12 bits. So YUV formats
seemingly drop the per-component padding, while RGB formats do not.
Internally it's consistent though: 10 bit YUV components are read as
16 bit, and the padding must be 0 (it's basically like an odd fixed-
point representation, rather than a bitfield).
bpp(bits-per-pixel) and depth(bit-depth for color component) can
be calculated from pixelformat technically but it requires massive
informations to be implemented in client side.
These subproperties are provided for convenience.
Enable asynchronous reading for external files. This excludes subtitle
files (so it's effectively enabled for audio files only), because most
subtitle files are fully read on loading, and running a thread for them
would just cause slowdowns and increase resource usage, without having
any advantages.
In theory, an external file could provide multiple tracks from the same
demuxer, but demux_start_thread() is idempotent, so the code can be
kept simple.
Should help with playing DASH with ytdl_hook.
