Also add a "raw" prefix for commands, which prevents property expansion.
The idea is that if the commands are generated by a program, it doesn't
have to know whether the command expands properties or not.
This is more consistent, and doesn't bother the user with ordering
rules when new prefixes are added.
Will break obscure uses of legacy commands: if the command is supposed
to be translated by the legacy command bridge, and if that command uses
one of the pausing* prefixes, the command can't be parsed. Well, just
use the new commands in this case.
This happens only if an option actually allocates memory (like strings).
Change filter API such that vf->priv is free'd by vf.c instead by the
filters. vf.c will free the option values as well.
Add the "vf" command, which allows changing the video filter chain at
runtime. For example, the 'y' key could be bound to toggle deinterlacing
by adding 'y vf toggle yadif' to the input.conf.
Reconfiguring the video filter chain normally resets the VO, so that it
will be "stuck" until a new video frame is rendered. To mitigate this, a
seek to the current position is issued when the filter chain is changed.
This is done only if playback is paused, because normal playback will
show an actual new frame quickly enough.
If vdpau hardware decoding is used, filter insertion (whether it fails
or not) will break the video for a while. This is because vo_vdpau
resets decoding related things on vo_config().
With the current semantics, there's no reason to disallow this.
(Although in my opinion, -vf should rather map to -vf-add than -vf-set,
however that is an independent issue from this change.)
Works like -vf-add, except if a filter already exists and has the same
parameters, it's removed instead of added.
Not really useful on the command line itself, but will make sense for
runtime filter changing in the following commit.
Until now, -vf-del required a list of indexes. This was a bit
inconvenient, so add support for using filter names too. Also simplify
the code a bit, doing the change would have been too painful otherwise.
This tried to use ctx->pic (last decoded AVFrame) for the frame bounds.
However, if av_frame_unref() on the AVFrame is called, the function will
reset _all_ AVFrame fields, even those which are not involved with
memory management. As result, mpcodecs_config_vo() was called with 0
width/height, which made the function exit early, instead of
reconfiguring the filter chain.
Go back to using mpcodecs_config_vo() directly. (That's what it did
before this VDCTRL was originally introduced; the original reason for
it disappeared.)
vo_vdpau actually reads past the image allocation when displaying a
non-mod 2 420p image. The vdpau API specifies that VdpVideoSurfacePutBitsYCbCr()
requires a height that is a multiple of 4, and surface allocations are
automatically rounded.
So allocate video images with rounded height. libavutil does the same,
so images coming directly from the decoder or from libavfilter are no
problem. (libavutil does this alginment explicitly, not just because the
decoded image size is aligned to macroblocks.)
The main() function is special, and omitting the return statement would
make it always return 0. And also, mpv_main() actually never returns, it
calls exit() through exit_player() instead. But change it anyway,
because it looks misleading.
This changes the code so that it does the same as MPlayer, mplayer2
and mpv before ref-counted AVFrame. The problem is that get_buffer2
is called with aligned frame dimensions, while get_buffer didn't. This
breaks the mpv video frame size change detection.
Followup to 8df7127. This refines the condition for front ordering the
condition to account for minimized or hidden state where the window should go
to the front only as a consequnce of user interaction.
FFmpeg (as well as Libav) have two layouts called "6.1":
AV_CH_LAYOUT_6POINT1 and AV_CH_LAYOUT_6POINT1_BACK. We call them "6.1"
and "6.1(back)". Change the default layout for 7 channels as well to
return the same layout as av_get_default_channel_layout(). (Looks a bit
questionable, but for now it's better to follow FFmpeg.)
When using --fs `vo_cocoa_fullscreen` was called from the primary thread. This
occurred inside `vo_cocoa_config_window` which is scheduled for excution on the
primary thread with libdispatch).
All of this caused spam from NSRecursiveLock in standard output.
When going in and going out of full screen the player lost information on the
movableByWindowBackground behaviour. There were some hacks in place to fix it
but they were broken with the recent native fullscreen changes in 74c15ec6.
This commit removes the problem at the root and removes the hacks. The delegate
method `isMovableByWindowBackground` seems to be called after setFrame and
setPresentationOptions so change fs state in opts before that.
Fixes#83
It turns out that ALSA's 4 channel layout is different from mpv's and
ffmpeg's 4.0 layout. Thus trying to do 4 channel output led to incorrect
remixing via lib{av,sw}resample.
Fix the default layouts for the internal filter chain as well, although
I'm not sure if it matters at all.
The libavresample version of the current Libav stable release lacks the
avresample_set_channel_mapping() function. (FFmpeg's libswresample seems
to be fine, because they added swr_set_channel_mapping() first.)
Add a cheap/slow workaround to do channel reordering on our own. We
don't use the recently removed MPlayer code (see commit 586b75a),
because that is not generic enough.
The functionality should be the same as with full-featured
libavresample, and any differences are bugs. It's probably slower,
though.
Apparently useful for dumping DVD. Could also be used to rip streams
with libquvi and such, but for that there are better tools. Actually
I doubt there aren't better tools to dump DVDs, but whatever, this was
a feature request, so I don't need a good reason.
af_reinit() is responsible for inserting automatic conversion filters
for channel remixing, format conversion, and resampling. We don't
require that a single filter can do all these (even though
af_lavrresample does nearly all of this, sometimes af_format has to be
used instead for format conversions). This makes setting up the chain
more complicated, and a way is needed to prevent endless appending of
conversion filters if a conversion is not possible.
Until now, this used a stupidly simple yet robust static retry limit to
detect failure. This is perfectly fine, and the limit (20) was good
enough to handle about ~5 filters. But with more filters, and if each
filter requires 3 additional conversion filters, this would fail. So
raise the limit to 4 retries per filter. This is still stupidly simple
and robust, but won't arbitrarily fail if the filter count is too large.
To make this easier, get rid of the direct mapping of the
AF_FORMAT_BITS_MASK bit field to number of bytes. This way we can throw
away the unused AF_FORMAT_48BIT and don't have to add ..._56BIT.
The snd_pcm_hw_params_test_format() call actually crashes in alsa-lib if
called with SND_PCM_FORMAT_UNKNOWN, so the already existing fallback
code won't work in this case.
Make all AOs use what has been introduced in the previous commit.
Note that even AOs which can handle all possible layouts (like ao_null)
use the new functions. This might be important if in the future
ao_select_champ() possibly honors global user options about downmixing
and so on.
The point is selecting a minimal fallback. The AOs will call this
through the AO API, so it will be possible to add options affecting
the general channel layout selection.
It provides the following mechanism to AOs:
- forcing the correct channel order
- downmixing to stereo if no layout is available
- allow 5.1 <-> 5.1(side) fallback
- handling "unknown" channel layouts
This is quite weak and lots of code/complexity for little gain. All AOs
already made sure the channel order was correct, and the fallback is of
little value, and could perhaps be done in the frontend instead, like
stereo downmixing with --channels=2 is handled. But I'm not really sure
how this stuff should _really_ work, and the new code will hopefully
provides enough flexibility to make radical changes to channel layout
negotiation easier.
If one of the input or output is an unknown layout, but the other is
known, it can still happen that channels are remixed randomly. Avoid
this by forcing default layouts in this case. (Doesn't work if the
channel counts are different.)
Now mpv's channel map is used to map each channel to a speaker. This
allows in theory for playback of any layout for which ao_openal
actually has a speaker defined. Also add the back-center (BC) speaker,
which allows playback of 6.0 audio. Enabling more layouts by adding
other speakers would be possible, but I'm not sure about the speaker
positions.
