We can render subtitles if a VO is open. Whether we're decoding video
(i.e. if mpctx->sh_video is set) doesn't really matter.
Subtitle display with --force-window still doesn't quite work yet,
because there's nothing to actually force redrawing of subtitles in this
mode.
This commit adds the --force-window option, which will cause mpv always
to create a window when started. This can be useful when pretending that
mpv is a GUI application (which it isn't, but users pretend anyway), and
playing audio files would run mpv in the background without giving a
window to control it.
This doesn't actually create the window immediately: it only does so
only after initializing playback and when it is clear that there won't
be any actual video. This could be a problem when starting slow or
completely stuck network streams (mpv would remain frozen in the
background), or if video initialization somehow is stuck forever in
an in-between state (like when the decoder doesn't output a video
frame, but doesn't return an error either). Well, we can pretend only
so much that mpv is a GUI application.
Seeking normally resets the VO and throws away the currently displayed
frame, so if you seek outside the video with --keep-open enabled, the
window would normally be "stuck" and not redraw properly, because there
is no source video frame that could be redrawn. To deal with this, a
precise seek to the position of the last displayed video frame was
issued.
This usually worked, but it can fail for formats where seeking is broken
or not possible (consider reading from a pipe).
Fix this by changing the semantics for vo_seek_reset(): now the video
frame is remembered even after seeking.
Note that this changes behavior a little when trying to seek outside of
a file with --keep-open enabled. Since no actual seek is done anymore,
the video will remain "frozen" on the previous position, and you can't
unpause or framestep to see the video between current position and
actual end of the video. If users complain, I might revert this commit.
Commit 884c179 attempted to make it possible to skip backwards through
the playlist, even for files which fail to intitialize, or play for a
very short time. This was also used to prevent mpv from looping forever
and doing nothing if --loop=inf is used, and no file in the playlist is
playable.
This broke looping of very short files, because mpv was assuming that
this case happened. But there are legitimate use cases.
Fix this by making the looping case special. Instead of checking whether
playback was "very short", check whether something could be decoded and
displayed/played. If yes, allow looping.
Until now, mouse positions were just passed to the core as-is, even if
the mouse coordinates didn't map to any useful coordinate space, like
OSD coordinates. Lua scripting (used by the OSC, the only current user
of mouse input) had to translate mouse coordinates manually to OSD space
using mp_get_osd_mouse_pos(). This actually didn't work correctly in
cases mouse coordinates didn't map to OSD (like vo_xv): the mouse
coordinates the OSC got were correct, but input.c was still expecting
"real" mosue coordinates for mouse areas.
Fix this by converting to OSD coordinates before passing the mouse
position to the core.
Do this so that MOUSE_LEAVE can't be combined with other keys. (E.g.
keep 'w' pressed, then move the mouse outside of the mpv window; it will
print a warning what w-MOUSE_LEAVE is not mapped.)
It appears the last run missed all mp_tmsg().
Since the command parser also prints messages, it needs a new parameter
to pass a log context. We go the easy way and just require the input_ctx
to be passed, and use its mp_log.
There is uninitialized memory access if the actual size isn't passed
along. In the worst case, this can cause a source to be loaded against
the uninitialized memory, causing a false count of found versus required
sources, preventing the "Failed to find ordered chapter part" message.
Nothing really accesses it. Subtitle initialization actually does in a
somewhat meaningful way, but there container size is probably fine, as
subtitles were always initialized before the first video frame was
decoded.
Now writing -1 to the 'aspect' property resets the video to the auto
aspect ratio. Returning the aspect from the property becomes a bit more
complicated, because we still try to return the container aspect ratio
if no frame has been decoded yet.
This is preliminary. There are still tons of issues, and any aspect
of scripting may change in the future. I decided to merge this
(preliminary) work now because it makes it easier to develop it, not
because it's done. lua.rst is clear enough about it (plus some
sarcasm).
This requires linking to Lua. Lua has no official pkg-config file, but
there are distribution specific .pc files, all with different names.
Adding a non-pkg-config based configure test was considered, but we'd
rather not.
One major complication is that libquvi links against Lua too, and if
the Lua version is different from mpv's, you will get a crash as soon
as libquvi uses Lua. (libquvi by design always runs when a file is
opened.) I would consider this the problem of distros and whoever
builds mpv, but to make things easier for users, we add a terrible
runtime test to the configure script, which probes whether libquvi
will crash. This is disabled when cross-compiling, but in that case
we hope the user knows what he is doing.
This time it broke because I didn't actually test compiling vo_vaapi.c,
and it was using a macro from mp_image.h, which implicitly assumed
FFALIGN was available. Screw that too, and copy the definition of
ffmpeg's FFALIGN to MP_ALIGN_UP, and move these macros to mp_comnon.h.
The code using FFSWAP was moved from vo_vaapi.c to vaapi.c, which didn't
include libavutil/common.h anymore, just libavutil/avutil.h. The header
avutil.h doesn't include common.h recursively in Libav, so it broke
there.
Add FFSWAP as MPSWAP in mp_common.h (copy pasted from ffmpeg) to make
sure this doesn't happen again. (This kind of stuff happens all too
often, so screw libavutil.)
This code is actually quite inefficient: it reuses the (slow, simple)
screenshot code. It uses an inefficient method to read the image
(vaGetImage() instead of vaDeriveImage()), allocates new memory for
each frame that is read, and it tries all image formats again each
time.
Also, in my tests it always picked NV12 as image format, which is not
ideal if you actually want to filter the video, and vo_xv can't handle
this format without conversion either.
However, a user confirmed that it worked for him, so everything is fine.
Merged from pull request #246 by xylosper. Minor cosmetic changes, some
adjustments (compatibility with older libva versions), and manpage
additions by wm4.

This wasn't enough and could lead to a cut off message shown on OSD.
Just make it dynamic, since we already use dynamic memory allocation
at this point anyway.
The problem with DVD/BD and playback resume is that most often, the
filename is just "dvd://", while the actual path to the DVD disk image
is given with --dvd-device. But playback resume works on the filename
only.
Add a pretty bad hack that includes the path to the disk image if the
filename starts with dvd://, and the same for BD respectively. (It's a
bad hack, but I want to go to bed, so here we go. I might revert or
improve it later, depending on user feedback.)
We have to cleanup the global variable mess around the dvd_device.
Ideally, this should go into MPOpts, but it isn't yet. Make the code
paths in mplayer.c take MPOpts anyway.
By default, libavformat uses UDP for rtsp playback. This doesn't work
very well. Apparently the reason is that the buffer sizes libavformat
chooses for UDP are way too small, and switching to TCP gets rid of this
issue entirely (thanks go to Reimar Döffinger for figuring this out).
In theory, you can set buffer sizes as libavformat options, but that
doesn't seem to help.
Add an option to select the rtsp transport, and make TCP the default.
Also remove an outdated comment from stream.c.
This is for properties that normally show a bar, and thus do not show an
OSD message (as per classic mplayer behavior). Setting an extra_msg
allows showing an OSD message anyway, except if OSD messages are
explicitly suppressed.
This refactors the whole show_property_osd() function a bit, and
replaces the weird sep field with a more general method.
Allows for example: --status-msg='${?pause==yes:(Paused) } ...' to
emulate the normal terminal status line. It's useful in other situations
too.
I'm a bit worried about extending this mini-DSL, and sure hope nobody
will implement a generic formula evaluator at some point in the future.
But for now we're probably safe.
In most cases, it's better if deinterlacing happens before any other
filtering, so prepend the filter to the user's filter list, instead
of appending it.
Instead of hardcoding a single filter. This might be helpful for
modeling the vaapi deinterlacer as a video filter. The idea is that a
software deinterlacer would be tried first, and if that fails (because
vaapi hardware decoding uses HW surfaces, which a software deinterlacer
does not accept), the vaapi filter would be tried.
The volume is set as soon as the audio chain is created again. This
works only in softvol mode. For system wide volume or otherwise
externally user controllable volume, this code is intentionally
disabled. It would be extremely weird if changing volume (while audio is
not initialized) would do nothing, and then suddenly change it when the
audio chain is created.
There's another odd corner case: the user-set volume will be thrown away
if it's set before the _first_ audio chain initialization. This is
because the volume restore logic recognizes a change from nothing to
softvol or an AO, and circumventing that would require additional code.
Also, we don't even know the start volume before that point.
Forcing the volume with --volume will can override the volume set during
no-audio mode, depending on the situation.
Note that this is intentionally never done if the AO or softvolume is
different, or if the current volume control method is thought to control
system wide volume (such as ALSA) or otherwise user controllable (such
as PulseAudio). The intention is to keep things robust and to avoid
messing with the user's audio settings as far as possible, while still
providing the ability to resume volume if it makes sense.
Refactor how mixer.c does volume/mute restoration and initialization.
Move to handling of --volume and --mute to mixer.c. Simplify the
implementation of these and hopefully fix bugs/strange behavior related
to using them as file-local options (this uses a somewhat dirty trick:
the option values are reverted to "auto" after initialization). Put most
code related to initialization and volume restoring in probe_softvol()
and restore_volume(). Having this code all in one place is less
confusing.
Instead of trying to detect whether to use softvol at runtime, detect it
at initialization time using AOCONTROL_GET_VOLUME (same with mute,
AOCONTROL_GET_MUTE). This implies we expect SET_VOLUME/SET_MUTE to work
if the GET variants work. Hopefully this is always the case.
This is also preparation for being able to change volume/mute settings
if audio is disabled, and for allowing restoring value with playback
resume.
It's quite unlikely, but functions like mp_find_user_config_file() can
return NULL, e.g. if $HOME is unset.
Fix all the code that didn't check for this correctly yet.
Remove the ifdef hell from mp_find_user_config_file(). Move the win32
specific code (for MinGW and Cygwin) to path-win.c. The behavior should
be about the same, but I can't be sure due to lack of testing and
because the old path.c code was hard to follow. (I expect those who care
about windows will fix things, should issues pop up - sorry.)
One difference is that the new code will always force MPV_HOME. It looks
like the old code preferred the mpv config dir in the exe dir if it
exists.
Also, make sure MP_PATH_MAX has enough space, even if the equivalent
wchar_t string is not 0-terminated with PATH_MAX (because apparently the
winapi doesn't require this). (Actually, maybe we should just kill all
uses of PATH_MAX/MP_PATH_MAX.)
The homepath variable was static, and its value was set to a stack
buffer. This means a second invocation of the function would trigger
undefined behavior. Moreover the stack buffer always went out of scope
before homepath was used.
Call update_subtitles() on every iteration of the playloop, so that
subtitle packets are read as soon as possible, instead of every time a
video frame is displayed. This helps in case the packet queue is swamped
with subtitle packets, which can happen with certain insane mkv files.
The change will simply cause the subtitle queue to be emptied on each
playloop iteration.
The timestamps update_subtitles() uses for display are the same before
and after this commit. (Important for files which have subtitle packets
with timestamps or duration not set.)
Instead of containing a format string within %w{...}, simply allow %w
to specify one item of a time format string. This is simpler, more like
other format specifiers (%t), and probably easier to use too.
This is for situations when repeated attempts at playing a playlist
entry failed, and playlist navigation becomes impossible due to that.
For example, it wasn't possible to skip backwards past an unplayable
playlist entry:
mpv file1.mkv doesntexist.mkv file3.mkv
You couldn't skip back to file1.mkv from file3.mkv. When running a
single "playlist_prev" command, doesntexist.mkv would be played, which
would fail to load. As reaction to the failure to load it, the next file
would be played, which is file3.mkv.
To make this even worse, the file could successfully load, but run only
for a split second. So just loading successfully isn't good enough.
Attempt to solve this by marking problematic playlist entries as failed,
and by having playlist_prev skip past such playlist entries. We define
failure as not being able to play more than 3 seconds (or failing to
initialize to begin with). (The 3 seconds are in real time, not file
duration.)
"playlist_prev force" still exhibits the old behavior.
Additionally, use the same mechanism to prevent pointless infinite
reloading if none of the files on the playlist exist. (See github issue
All in all, this is a heuristic, and later adjustments might be
necessary.
Note: forward skips (playlist_next) are not affected at all. (Except for
the interaction with --loop.)
This is commonly used to disable the screensaver with broken/non-
standard X screensavers. During pause, the screensaver should not be
disabled, so not calling this command while paused seems sensible.
See github issue #236.
They are rarely useful in my opinion.
This commit was mainly motivated by this message:
Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using a tool like VirtualDub or avidemux to fix it.
It's what's left over from the "Invalid and inefficient vfw-avi..."
warning that used to be printed when playing avi/divx files. Although
the new message is much better, it's still rather useless and poses
more questions than it answers. Besides, nobody wants to remux a file
when playing it, especially not if playback appears to be completely
fine. (There are some claims that these files raise CPU usage, but even
my old crappy CPU can decode low res avi/divx files at real time at
about x35 playback speed.)
