"drop-frame-count" -> "decoder-frame-drop-count"
"vo-drop-frame-count" -> "frame-drop-count"
This gets rid of the backwards "drop-frame" part in the name.
Maybe calling the new property "frame-drops" would be better, but there
are already a bunch of similar properties that end in "-count".
vo_opengl used to have it as sub-option, which made it very hard to pass
down option values to backends in a generic way (even if these options
were completely backend-specific). For --opengl-dcomposition we used a
VOFLAG to deal with this. Fortunately, sub-options are gone, and we can
just add it as global option.
Move the option to context_angle.c and add it as global option. I
thought about adding a mechanism to let backends declare options, which
would get magically picked up my m_config instead of having to add them
to the global option list manually (similar to VO vo_driver.options),
but decided against this complexity just for 1 or 2 backends. Likewise,
it could have been added as a single option to avoid the boilerplate of
an option struct, but then again there are probably going to be more
angle suboptions, and it's cleaner.
Scale the window by the assumed DPI scaling factor, using 96 DPI as
base. For example, a screen that reports 192 DPI is assumed to have a
DPI scale factor 2. The window will then be created with twice the size.
For robustness reasons, we accept only integer DPI scales between 1 and
9. We also error out if the X and Y scales are very different, as this
most likely indicates a multiscreen system with botched size reporting.
I'm not sure if reading the X server's DPI is such a good idea - maybe
the Xrdb "Xft.dpi" value should be used instead. The current method
follows what xdpyinfo does.
This can be disabled with --hidpi-window-scale=no.
our constrainFrameRect prevents our window from positioning itself ontop
of the menubar, which is unwanted for a fullscreen window. this always
positioned our window vertically at -22/-23pt when going into fullscreen
because of the menubar. this bug doesn't show on newer versions of OS X
since the various flags we set force the window position. on OS X 10.9
though the fullscreen window was shifted 22pt downwards. even though
this bug doesn't show on newer OS X versions, it should still be fixed
for a possible behaviour changes in future version.
Fixes#4044
everytime we switched to a new video file a new displaylink was
initialised and started, but the old one was not stopped and released
beforehand. this lead to several displaylink callback calls per swap,
depending on how many files were switched beforehand. moving the
displaylink init call to the cocoa init functions will ever only init
one displaylink.
Fixes#4031
we are calling the method on a NSWindow object that may not respond to
that call, since its a method of MpvVideoWindow. add the method to our
protocol and rename that protocol to reflect the change.
in some circumstances cocoa isn't able to enter or exit fullscreen but
we still set window sizes and flags accordingly. this leaves us in a
hanging state between fullscreen and window. it also prevents the
toggleFullscreen method and its events to work properly afterwards. in
that state it's impossible to enter or exit this 'semi-fullscreen'.
add a proper fallback to recover from this state.
Fixes#4035
Disabling cache readahead by default until at least 1 track is selected
is mainly for external files and such, where you don't want them to use
up resources until they're actually used.
It doesn't make sense to disable the cache for the demuxer opened for
prefetch. Also, it's fine to let it do that for the main file too (doing
or not doing it is of little consequence). That saves us from having to
distinguish them.
Since for mpv CLI, the player state is a singleton, full prefetching is
a bit tricky. We do it only on the demuxer layer.
The implementation reuses the old "open thread". This means there is
significant potential for regressions even if the new option is not
used. This is made worse by the fact that I barely tested this code.
The generic mpctx_run_reentrant() wrapper is also removed - this was its
only user, and its remains become part of the new implementation.
As preparation for file prefetching, we basically have to get rid of
using mpctx->playback_abort for the main demuxer (i.e. the thing that
can be prefetched). It can't be changed on a running demuxer, and always
using the same cancel handle would either mean aborting playback would
also abort prefetching, or that playback can't be aborted anymore.
Make this more flexible with some refactoring.
Thi is a quite shitty solution if you ask me, but YOLO.
Apparently you set the native sample rate when passing through AC3.
This fixes passthrough with 44100 Hz AC3.
Avoid opening a decoder for this and only open the parser. (Hopefully
DTS will also support this some time in the future or so - having to
open a decoder just to get the profile is dumb.)
Since the only way to detect the API is by a version check, this had to
wait until the patches were actually pushed to FFmpeg git (which now
happened).
Since this does not include the new magic GPU memcpy libavutil function
yet, the new vaapi code would be slower if copy mode (like vaapi-copy)
is used. This would be quite bad to use by default, so check for the
function, and if not present, disable the new vaapi code. This
effectively disables it by default on FFmpeg.
(We assume that if the new GPU memcpy exists, vaapi's AVHWFramesContext
implementation will use it.)
libavutil does this for us. Although the new vaapi decode API does not
strictly introduce or even need av_image_copy_uc_from(), it's implied
that it will be present if the new decode API is present - even if it's
not, we can't use our own SSE code with it anyway.
Introduce the --opengl-hwdec-interop option, which replaces
--hwdec-preload. The new option allows explicit selection of the interop
backend.
This is relatively complex, and I would have preferred not to add this,
but it's probably useful to debug certain problems. In exchange, the
"new" option documents that pretty much any but the simplest use of it
will not be forward compatible.
Replace the old code, that played games to evade thread-safety issues,
with newer thread-safe option access functions.
This also means mp_opengl_create() doesn't need to cache the hwdec
settings anymore. (They're applied in mpv_opengl_cb_init_gl() instead.)
Tried to decode a High 4:2:2 file, since libavcodec code seemed to
indicate that it's supported. Well, it decodes to garbage.
I couldn't find out why ffmpeg.c actually appears to reject this
correctly. The API seems to be fine with, just that the output is
garbage.
Add a hack for now.
Successful decoding of a frame resets ctx->hwdec_fail_count to 0 - which
us ok, but prevents fallback if it fails if --vd-lavc-software-fallback
is set to something higher than 1.
Just fail it immediately, since failing here always indicates some real
error (or OOM), not e.g. a video parsing error or such, which we try to
tolerate via the error counter.
Use the libavutil vdpau frame allocation code instead of our own "old"
code. This also uses its code for copying a video surface to normal
memory (used by vdpau-copy).
Since vdpau doesn't really have an internal pixel format, 4:2:0 can be
accessed as both nv12 and yuv420p - and libavutil prefers to report
yuv420p. The OpenGL interop has to be adjusted accordingly.
Preemption is a potential problem, but it doesn't break it more than it
already is.
This requires a bug fix to FFmpeg's vdpau code, or vdpau-copy (as well
as taking screenshots) will fail. Libav has fixed this bug ages ago.
In a way it can be reused. For now, sw_format and initial_pool_size
determination are still vaapi-specific. I'm hoping this can be eventally
moved to libavcodec in some way. Checking the supported_formats array is
not really vaapi-specific, and could be moved to the generic code path
too, but for now it would make things more complex.
hw_cuda.c can't use this, but hw_vdpau.c will in the following commit.
Even though the title list code was copied from FFmpeg/libbluray,
I didn't check that mpv used 0-based title indexing.
$ mpv bd://1 --bluray-device=. --msg-level=bd=v
[bd] Opening bd://
[bd] List of available titles:
[bd] idx: 1 duration: 00:00:36 (playlist: 00000.mpls)
[bd] idx: 2 duration: 01:31:30 (playlist: 00001.mpls)
[bd] idx: 3 duration: 00:00:50 (playlist: 00003.mpls)
bd://1 actually opens idx 2 from the list, not 1.
bd://mpls/1 opens playlist 00001.mpls as expected.
With this commit:
$ mpv bd://1 --bluray-device=. --msg-level=bd=v
[bd] Opening bd://
[bd] List of available titles:
[bd] idx: 0 duration: 00:00:36 (playlist: 00000.mpls)
[bd] idx: 1 duration: 01:31:30 (playlist: 00001.mpls)
[bd] idx: 2 duration: 00:00:50 (playlist: 00003.mpls)
should play the expected idx 1.
Requires a bunch of hacks:
- we access AVFilterLink.hw_frames_ctx. This is not a public API in
FFmpeg and Libav. Newer FFmpeg provides an accessor
(av_buffersink_get_hw_frames_ctx), but it's not available in Libav or
the current FFmpeg release or Libav. We need this value after filter
graph creation, so We have no choice but to access this.
One alternative is making filter creation and format negotiation
fully lazy (i.e. delay it and do it as filters are output), but this
would be a huge change.
So for now, we knowingly violate FFmpeg's and Libav's ABI and API
constraints because they don't provide anything better.
On newer FFmpeg, we use the (quite ugly) accessor, though.
- mp_image_params doesn't (and can't) have a field for the frames
context AVBufferRef. So we pass it via vf_set_proto_frame(), and even
more hacks.
- if a filter needs a hw context, but we haven't created one yet
(because normally we create them lazily), it will fail at init.
- we allow any hw format now, although this could go horrible wrong.
Why all this effort? We could move hw deinterlacing filters etc. to
FFmpeg, which is a very worthy goal.
Instead of using the awful older "API" that passed the parameters
formatted as string. AVBufferSrcParameters is also a prerequisite for
hardware frame filtering support.
Because it allows easier testing of filters + hwdec.
Make the texture setup code a bit more generic so it doesn't get too
much of a mess. We also use the GL renderer utility function
gl_find_unorm_format(), which saves us additional work with OpenGL's
semi-redundant format specifiers.
Can break things quite badly.
Example: reloading a plugin linked against GTK 3.x can cause a segfault
if you call dlclose() on it. According to GTK developers, unloading the
GTK library is unsupported.
Give scripting backends a proper name, instead of calling everything
"scripts".
Log client exit directly in client.c, as that is more general (doesn't
change actual output).
If hardware decoding is enabled (via --hwdec anything), the player was
printing an informational message that software decdoing is used.
Basically, this confuses users, because they think there is a problem or
such. Just disable the message, it's semi-useless anyway.
This was suggested on IRC, after yet another user was asking why this
message was shown (with a follow up discussion which CPUs can decode
what kind of video codecs).
EGL rendering + new decode API didn't work due to a certain libva bug
with sort-of legacy API use hitting again. It will report the wrong
vaapi pixel format. It's old code and always nv12 anyway, so stop
worrying about it.
There are going to be users who have a Mesa installation which do not
support 10 bit, but a GPU which can decode to 10 bit. So it's probably
better not to hardcode whether it is supported.
Introduce a more general way to signal supported formats from renderer
to decoder. Obviously this is imperfect, because it still isn't part of
proper format negotation (for example, what if there's a vavpp filter,
which accepts anything). Still slightly better than before.
I don't know any way to probe for vaapi dmabuf/EGL dmabuf support
properly (in particular testing specific formats, not just general
availability). So we stay with the current approach and try to create
and map dummy surfaces on init to probe for support. Overdo it and check
all formats that AVHWFramesConstraints reports, instead of only NV12 and
P010 surfaces.
Since we can support unknown formats now, add explicitly checks to the
EGL/dmabuf mapper code to reject unsupported formats. I also noticed
that libavutil signals support for RGB0/BGR0, but couldn't get it to
work. Remove the DRM formats that are unused/didn't work the way I tried
to use them.
With this, 10 bit decoding + rendering should work, provided you have
a capable CPU and a patched Mesa. The required Mesa patch adds support
for the R16 and GR32 formats. It was sent by a Kodi developer to the
Mesa developer mailing list and was not accepted yet.
For convenience. Since we still have code that works even if creating a
AVHWDeviceContext fails, failure is ignored. (Although currently, it
succeeds creation even with the stale/abandoned vdpau wrapper driver.)
Application of options in the default section is "delayed" until the
whole config file is read in order to allow profile forward references.
This was run at the end of parsing a config file - but because of
"include" options, this means it's not always called at the end of the
main config file.
Use the recursion counter to prevent it from being processed after each
"include" option. This also gets rid of the resulting unintended
infinite recursion (which eventually stopped and failed loading the
config file) due to m_config_finish_default_profile() processing the
"include" option again.
Fixes#4024.
For surfaces allocated by libavutil, we assume that the sw_format (i.e.
in hw_subfmt in mp_image_params) is always correct. The API guarantees
that it explicitly sets the equivalent vaapi format on surface
allocation.
For surfaces allocated by mpv's old vaapi code, we explicitly retrieve
the format right after decoding. Unless the driver magically changes the
format asynchronously, it will still be correct once the surface reaches
the renderer.
In both cases, checking the format again is obviously redundant. In
addition, it doesn't require us to maintain a libva fourcc <-> mpfmt
table and the va_fourcc_to_imgfmt() function. This also unbreaks 10 bit
rendering support (still disabled by default).
