i tried being smart and handle aspect ratio differences manually via
atomic drawing and resizing to aspect fitted frames. there were a few
issues with that. like unexpected visibility of certain System GUI
elements on entering fullscreen or visually dropped frames due to the
atomic drawing. now we rely on system mechanics to keep the proper
aspect ratio of our layer, the recommended way. as a side effect it also
fixes a segfault.
Fixes#5581
It turns out that Mali drivers are likely broken, and do not return
GBM_FORMAT_ARGB8888 (they return GBM_FORMAT_XRGB8888) when getting
EGL_NATIVE_VISUAL_ID for any EGLConfig, even though the resulting
EGLConfig appears to be capable of alpha.
It could also be potentially useful to allow an ARGB EGLConfig used
with an XRGB framebuffer on some platforms, so we do that. (cf. weston)
Unrelated indentation fix in gbm_format_to_string.
Naturally, there's more than one fourcc that indicates an mjpeg
stream.
I have a particular ancient webcam here (Logitech QuickCam Messanger)
that only supports the single 'JPEG' format, but there are other
devices out there which support both 'JPEG' and 'MJPG' with no visible
differences, and others where the streams are slightly different.
Regardless of those details, it remains correct to treat 'JPEG'
the same as 'MJPG' from a stream consumption perspective.
This adds key bindings for some semi-popular features. It also tries to
cleanup some old bindings. For example w/e for panscan is now changed to
w/W. In all cases, the old bindings are still kept and work, though.
Part of an ongoing attempt to cleanup the default key bindings.
See #973 for some context.
this API was introduced in c5e4538 solely for the use with cocoa-cb and
was not public. with the port to the new API in 760d471 it is now unused
and can safely be removed.
it's possible to get a function pointer through a closure after all in
swift. remove the GL dummy function from the c header and do it in the
swift code instead.
After switching, the playback state was not reset, which could leave it
in a strange, pause like state, that could be fixed by e.g. seeking.
This seems to be an older regression - it's even in 0.27.
Sometimes, playback needs to be fully uninitialized and reinitialized
without "officially" closing and reopening the playlist entry. This
happens with PT_RELOAD_FILE, which is triggered by edition switching and
also DVD/BD title switching. (Not really sure why it goes through so
much pain for such obscure cases. All it gains is not resetting "local"
options, and not signaling a reload to the client API. Whatever.)
The recent filter change freed filter_root too early without recreating
it, so it crashed on edition switching.
Fixes#5587.
If you used --aufio-file=file.mkv, and file.mkv included a video track
marked as default, then the logic in select_default_track() would pick
the video track from file.mkv. This is 100% broken, so fix it.
The playback start logic explicitly waits until the first frame has been
displayed. Usually this will introduce a wait of 1 vsync. For normal
playback this doesn't matter, but with respect to low latency needs,
this only leads to additional data getting queued up in the demuxer or
network buffers.
Another thing is that the timing logic decodes 1 frame ahead (= 1 frame
extra latency) to determine the exact duration of a frame.
To be fair, there doesn't really seem to be a hard reason why this is
needed. With the current code, enabling the option does lead to A/V
desync sometimes (if the demuxer FPS is too inaccurate), and also frame
drops at playback start in some situations. But this all seems to be
avoidable, if the timing logic were to be rewritten completely, which
should probably happen in the future. Thus the new option comes with the
warning that it can be removed any time. This is also why the option has
"hack" in the name.
Well I guess it doesn't help that much.
Also add some stuff that might help to the manpage.
The fundamental problem with some "live" sources (e.g. x11grab) is
actually that the player gets behind initially, and never thinks it has
to catch up. This is also why --untimed can help.
It's a mess: mp3 files have user tags as global metadata (because the
id3v2 tag is global and there is only 1 stream), while OGG files have it
per-track (because it's per-stream on the lowest level). mpv needs to
try to make something nice out of the mess.
It did so by trying to detect audio-only OGG files, and then copying the
per-stream metadata to the global metadata. Make the heuristic for
detecting this slightly more clever, so it works for files with extra,
unrelated streams, like the awful libavformat cover art hack.
Fixes#5577.
Useful for libavfilter. Somewhat risky, because we can't ensure the
consistency of the unknown side data (but this is a general problem with
side data, and libavfilter filters will usually get it wrong too _if_
there are conflict cases).
Fixes#5569.
We must not create new references herem because mp_image_new_ref() is
called later, and actually creates new references (including doing
actual error checking). Blame C, not me.
It appears some (or all) mkv files with EAC3 are muxed in a way that
breaks FFmpeg's spdifenc. I suspect it's because either dependent
substream packets are localted in their own packets, or the reverse. Or
possibly this is case where the muxer did not respect packet boundaries
at all. Enabling the EAC3 parser seems to fix this anyway, because why
waste your precious time on retarded Dolby bullshit technology? (Which
idiot came up with this shitty substream garbage?)
Observed with dolby_digital_plus_channel_check_lossless-DWEU.mkv.
Fixes#5578.
I think DASH playback tends to work much better with FFmpeg's DASH
demuxer, which requires libxml2.
For nvdec, FFmpeg git master now requires the external nvidia headers,
since the builtin ones were removed.
the NSWindowButton enum was moved to be a member of NSWindow and renamed
to ButtonType in SDK 10.13. apparently that wasn't documented anywhere.
not even in the SDK changes Document and the official Documentations
makes it look like it was always like this. the old NSWindowButton enum
though is still around on SDK 10.13 or at least got a typealias. so we
will just use that.
The purpose of the new API is to make it useable with other APIs than
OpenGL, especially D3D11 and vulkan. In theory it's now possible to
support other vo_gpu backends, as well as backends that don't use the
vo_gpu code at all.
This also aims to get rid of the dumb mpv_get_sub_api() function. The
life cycle of the new mpv_render_context is a bit different from
mpv_opengl_cb_context, and you explicitly create/destroy the new
context, instead of calling init/uninit on an object returned by
mpv_get_sub_api().
In other to make the render API generic, it's annoyingly EGL style, and
requires you to pass in API-specific objects to generic functions. This
is to avoid explicit objects like the internal ra API has, because that
sounds more complicated and annoying for an API that's supposed to never
change.
The opengl_cb API will continue to exist for a bit longer, but
internally there are already a few tradeoffs, like reduced
thread-safety.
Mostly untested. Seems to work fine with mpc-qt.
The stdatomic emulation adds "_" to each variable used inside the
macros, to avoid that compilers print -Wshadow warnings for identifiers
that are also used in surrounding code. Do this more consistently,
because new warnings have been showing up.
when resizing async it's possible that the layer, and the underlying gl
surface, is stretched on an aspect ratio change. to prevent that we do
an atomic resize (resize and draw at the same time). usually max one
unique frame should be dropped but it's possible, depending on the
performance, that more are dropped.
the title bar is now within the window bounds instead of outside. same
as QuickTime Player. it supports several standard styles, two dark and
two light ones. additionally we have properly rounded corners now and
the borderless window also has the proper window shadow.
Also make the earliest supported macOS version 10.10.
Fixes#4789, #3944
By blocking the VT switcher signal in the VO thread we get less races
and other oddities.
This gets rid of tearing (at least for me) when VT switching with
--gpu-context=drm.
crtc_setup gets called on VT reacquire as well as during normal setup. When
called during VT reacquire p->front_buf might not be 0, so the maths was wrong,
and could cause array OOB errors. Use mathematically correct (for negative
numbers) modulo to always pick the farthest away buffer (should work
even for larger values of BUF_COUNT).
The VT switcher was being set up, but it was being neither polled nor
interrupted.
Insert wait_events and wakeup functions based on those from vo_drm,
and add return early in drm_egl_swap_buffers if p->active isn't set.
This should get basic VT switching working, however there will likely
still be some random glitches. Switching between mpv and X11/weston is
unlikely to work satisfactorily until we can solve the problems with
drmSetMaster and drmDropMaster.
