The plan is to nuke the custom filter chain completely. It's not clear
what will happen to the still needed builtin filters (mostly hardware
deinterlacing and vf_vapoursynth). Most likely we'll replace them with
different filter chain concept (whose main purpose will be providing
builtin things and bridging to libavfilter).
The undocumented "warn" options are there to disable deprecation
warnings when the player inserts filter automatically.
The same will be done to audio filters, at a later point.
And also change input.conf to make all screenshots async. (Except the
every-frame mode, which always uses synchronous mode and ignores the
flag.) By default, the "screenshot" command is still asynchronous,
because scripts etc. might depend on this behavior.
This is only partially async. The code for determining the filename is
still always run synchronously. Only encoding the screenshot and writing
it to disk is asynchronous. We explicitly document the exact behavior as
undefined, so it can be changed any time.
Some of this is a bit messy, because I wanted to avoid duplicating the
message display code between sync and async mode. In async mode, this is
called from a worker thread, which is not safe because showing a message
accesses the thread-unsafe OSD code. So the core has to be locked during
this, which implies accessing the core and all that. So the code has
weird locking calls, and we need to do core destruction in a more
"controlled" manner (thus the outstanding_async field).
(What I'd really want would be the OSD simply showing log messages
instead.)
This is pretty untested, so expect bugs.
Fixes#4250.
This wasn't enabled if no stream cache was used. It can work with only
the demuxer cache.
In theory this could be always enabled (even for local files), but still
try to avoid this, and enable it only if the source is marked as
potentially being a "network" stream. The intention is mostly to enable
it for the youtube-dl pseudo-DASH support.
The 'sub' and 'audio' configuration subdirectories are supposed to
be fallbacks for sub-paths and audio-file-paths respectively, but
they weren't being scanned even if they existed.
This is a bit approximate, because we rely on the pixel format changing
if the hardware decoding changes. This is not always true, as the pixel
format for software decoded video and hardware decoded video copied back
to CPU RAM could be the same. (Not sure if that is actually the case for
any supported cases.)
But for now this should fix most of #4289.
Basically, see the example in input.rst.
This is better than the "old" vf-toggle method, because it doesn't
require the user to duplicate the filter string in mpv.conf and
input.conf.
Some aspects of this changes are untested, so enjoy your alpha testing.
Will still hide playlist items with long enough filenames and osd-font-size
but not as soon.
osc messages should now preserve their scaling with fullscreen toggling and
cycling through audio-only files and files with video.
Closes#4081, #4083, #4102
Requested. The property semantics are a bit muddy due to lack of effort.
Anticipated use is different display of cache status, so it should not
matter anyway.
This is just a pointless refactor with the only goal of making
image_writer_opts.format a number.
The pointless part of it is that instead of using some sort of arbitrary
ID (in place of a file extension string), we use a AV_CODEC_ID_. There
was also some idea of falling back to the libavcodec MJPEG encoder if
mpv was not linked against libjpeg, but this fails. libavcodec insist on
having AV_PIX_FMT_YUVJ420P, which we pretend does not exist, and which
we always map to AV_PIX_FMT_YUV420P (without the J indicating full
range), so encoder init fails. This is pretty dumb, but whatever. The
not-caring factor is raised by the fact that we don't know that we
should convert to full range, because encoders have no proper way to
signal this. (Be reminded that AV_PIX_FMT_YUVJ420P is deprecated.)
This also will set image=NULL, if the video frame is marked as hwaccel,
and could not be copied to normal RAM. This will probably change the
error message (due to screenshot_get() returning NULL, instead of making
image conversion fail at a later point), but the behavior is the same
anyway.
Fixes theoretical lock-order issues found by Coverity. Calling these
inside the log is unnecessary anyway, because they have their own
locking, and because mpv_detach_destroy() needs to be called by someone
who has exclusive access to the mpv_handle (it's basically a destructor
function). The lock order issues comes from the fact that they call back
into the client API implementation to broadcast events and such.
This was added for A-B loops, but it looks like commit a1dec6f5 made
this code unnecessary. Remove it, because it has the annoying
side-effect of blocking playback stop when seeking past the end.
When pausing, we sent BOCTRL_PAUSE and VOCTRL_RESTORE_SCREENSAVER. These
essentially wait until the video frame has been rendered. This is a
problem with the opengl-cb, if GL rendering is done in the same thread
as libmpv uses. Unfortunately, it's allowed to use opengl-cb this way.
Logically speaking, it's a deadlock situation, which is resolved with a
timeout. This can lead to quite ugly effects, like the on-pause frame
not being rendered until the timeout has passed. It has been interpreted
as video continuing to play.
Resolve this by simply not blocking on pause. Make the screensaver
controls async, and handle sending VOCTRL_PAUSE in the VO thread.
(All this could be avoided by redoing the internal VO API.)
Also see #4152.
Currently, tracks have always associated streams, so there can't be a
NULL dereference on the next line. But all the code is written with the
possibility in mind that we might want tracks without streams, so make
it consistent.
Found by coverity.
Not so important by itself, but important for when we replace the vf
libavfilter wrapper with the common implementation. (Which will
hopefully happen, but not too soon.)
Preparation for enabling hw filters. mp_image_params can't have an
AVHWFramesContext reference (because it can't hold any allocations, and
isn't meant to hold "active" data in the first place.
So just use a mp_image. It has all real data removed, because that would
essentially leak 1 frame once the decoder or renderer don't need it
anymore.
The AVFrame in the tmp_frame field was never actually deallocated.
Since this AVFrame holds data temporarily only, and is unreferenced
immediately after use, there is actually no need to make it per-pad, so
simplify it a bit.
(There's also no real value in caching this tmp_frame at all, but I
guess it makes the control flow slightly simpler.)
Using these was a temporary solution while some compilers implemented
the underlying atomic mechanisms, but not the C11 language parts (or
that's what I guess). Not really useful for us anymore. Also, there is
the slight risk of having subtly incorrect semantics by using
potentially changing compiler internals and such.
Seen with a VOD of a recently ended livestream on Youtube.
They seem to use segmented DASH but unlike normal Youtube
segmented DASH, the segments don't seem to need the initialization
segment.
The video actually fails to start to play if the init segment is
prepended with a lot of 'Found duplicated MOOV Atom. Skipped it' errors
popping up.
If we have a disconnected output, read data only passively (and don't
cause input to be written). Otherwise, we're in danger of making
libavfilter queue too many frames on other outputs which are connected
to the same input, but don't read as quickly.
Also don't set pad->output_needed in this specific case, because it
would nonsensically make lavfi_process() return true, even if nothing is
going on.
This commit breaks if there is a simple filter chain with a connected
input, but a disconnected output, like
--lavfi-complex='[aid1] copy [ao]'
and the audio output didn't initialize correctly. This will eventually
starve video as the audio packet queue get full (it will print a
warning, and then assume video EOF and exit).
But whatever.
Probably fixes#4118.
We use the metadata provided by youtube-dl to sort-of implement
fragmented DASH streaming.
This is all a bit hacky, but hopefully a makeshift solution until
libavformat has proper mechanisms. (Although in danger of being one
of those temporary hacks that become permanent.)
