Make the VO<->decoder interface capable of supporting multiple hwdec
APIs at once. The main gain is that this simplifies autoprobing a lot.
Before this change, it could happen that the VO loaded the "wrong" hwdec
API, and the decoder was stuck with the choice (breaking hw decoding).
With the change applied, the VO simply loads all available APIs, so
autoprobing trickery is left entirely to the decoder.
In the past, we were quite careful about not accidentally loading the
wrong interop drivers. This was in part to make sure autoprobing works,
but also because libva had this obnoxious bug of dumping garbage to
stderr when using the API. libva was fixed, so this is not a problem
anymore.
The --opengl-hwdec-interop option is changed in various ways (again...),
and renamed to --gpu-hwdec-interop. It does not have much use anymore,
other than debugging. It's notable that the order in the hwdec interop
array ra_hwdec_drivers[] still matters if multiple drivers support the
same image formats, so the option can explicitly force one, if that
should ever be necessary, or more likely, for debugging. One example are
the ra_hwdec_d3d11egl and ra_hwdec_d3d11eglrgb drivers, which both
support d3d11 input.
vo_gpu now always loads the interop lazily by default, but when it does,
it loads them all. vo_opengl_cb now always loads them when the GL
context handle is initialized. I don't expect that this causes any
problems.
It's now possible to do things like changing between vdpau and nvdec
decoding at runtime.
This is also preparation for cleaning up vd_lavc.c hwdec autoprobing.
It's another reason why hwdec_devices_request_all() does not take a
hwdec type anymore.

nvdec aka cuvid aka cuda should work much better than vdpau, and support
newer codecs (such as vp9), and more advanced surface formats (like 10
bit).
This requires moving the d3d hwaccels in the autoprobe order, since on
Windows, d3d decoding should be preferred over nvidia proprietary stuff.
Users of older drivers will need to force --hwdec=vdpau, since it could
happen that the vo_gpu cuda hwdec interop loads (so the vdpau interop is
not loaded), but the hwdec itself doesn't work.
I expect this does not break AMD (which still needs vdpau for vo_gpu
interop, until libva is fixed so it can fully support AMD).

When the ifdeffery for the frame_params API was added, the new code
accidentally didn't include this.
|
|
|
|
|
|
|
|
| |
All this code used to be required by the old variants of the libavcodec
hw decoding APIs. Almost all of that is gone, although the mediacodec
API unfortunately still pulls in some old stuff (but not all of it).
(mediacodec build/functionality is untested, but should work.)

All of this was dead code and completely unused.
get_buffer2_hwdec() is the biggest chunk. One unfortunate thing about it
is that, while it was active, it could perform a software fallback much
faster, because it didn't have to wait until a full frame is decoded (it
actually decoded a full frame, but the current code has to decode many
more frames due to the codec delay, because the current code waits until
the API returns a decoded frame.) We should probably restore the latter,
although since it's an optional optimization, and the current behavior
doesn't change with the removal of this code, don't actually do anything
about it.
|
|
|
|
|
| |
And move the remaining code (just 2 struct constant definitions) to
vd_lavc.c.
|

This is where it should be. It only wasn't because of an old libavcodec
bug, that returned the side data only on every IDR. This required some
sort of caching, which is now dropped. (mp_image wouldn't have been able
to do this kind of caching, because this code is stateless.) We don't
support these old libavcodec versions anymore, which is why this is not
needed anymore.
Also move initialization of rotation/stereo stuff to dec_video.c.

This simply didn't work. Unlike cuda-copy, this is a true hwaccel, and
obviously we need to provide it a device.
Implement this in a relatively generic way, which can probably reused
directly by videotoolbox (not doing this yet because it would require
testing on OSX).
Like with cuda-copy, --cuda-decode-device is ignored. We might be able
to provide a more general way to select devices at some later point.

This is just a dumb consequence of HWDEC_ types somehow being part of
both decoder and VO. Obviously, the VO should only care about supporting
specific hardware surface types or providing specific device types, but
until they are separated, stupid unintuitive mismatches will occur.
|
|
|
|
|
|
| |
Fist we were required to use them for ABI compat. reasons (and other
BS), now they're deprecated and we're supposed to access them directly
again.
|

See manpage additions.
(In ffmpeg-mpv and Libav, this is still called "cuvid". Libav won't work
yet, because it has no frame params support yet, but this could get
fixed soon.)
|
|
|
|
|
|
|
|
| |
This removes the need for codec- and API-specific knowledge in the
libavcodec hardware acceleration API user. For mpv, this removes the
need for vd_lavc_hwdec.pixfmt_map and a few other things. (For now, we
still keep the "old" parts for the sake of supporting older Libav, and
FFgarbage.)

Should speed up seeks.
(Unfortunately it's useless for backstepping. Backstepping is like
precise seeking, except we're unable to drop frames, as we can't know
the previous frame if we drop it.)

The new_segment field was used to track the decoder data flow handler of
timeline boundaries, which are used for ordered chapters etc. (anything
that sets demuxer_desc.load_timeline). This broke seeking with the
demuxer cache enabled. The demuxer is expected to set the new_segment
field after every seek or segment boundary switch, so the cached packets
basically contained incorrect values for this, and the decoders were not
initialized correctly.
Fix this by getting rid of the flag completely. Let the decoders instead
compare the segment information by content, which is hopefully enough.
(In theory, two segments with same information could perhaps appear in
broken-ish corner cases, or in an attempt to simulate looping, and such.
I preferred the simple solution over others, such as generating unique
and stable segment IDs.)
We still add a "segmented" field to make it explicit whether segments
are used, instead of doing something silly like testing arbitrary other
segment fields for validity.
Cached seeking with timeline stuff is still slightly broken even with
this commit: the seek logic is not aware of the overlap that segments
can have, and the timestamp clamping that needs to be performed in
theory to account for the fact that a packet might contain a frame that
is always clipped off by segment handling. This can be fixed later.

This commit allows to use the AV_PIX_FMT_DRM_PRIME newly introduced
format in ffmpeg that allows decoders to provide an AVDRMFrameDescriptor
struct.
That struct holds dmabuf fds and information allowing zerocopy rendering
using KMS / DRM Atomic.
This has been tested on RockChip ROCK64 device.

The mechanism introduced in b135af6842bf assumed AVHWFramesContext would
be enough. Apparently it's not - the intended use with Rockchip (not
Rokchip btw.) requires accessing actual frame data in order to access
the AVDRMFrameDescriptor struct.
Just pass the entire mp_image to the new function. This is more
flexible, although it slightly worries me that it will be less reusable
for things which require setting up mp_image_params before any real
frames are processed (such as filters).

The same should happen with any other side data that matters to mpv,
otherwise filters will drop it.
(No, don't try to argue that mpv should use AVFrame. That won't work.)
ffmpeg_garbage() is copy&paste from frame_new_side_data() in FFmpeg
(roughly feed201849b8f91), because it's not public API. The name
reflects my opinion about FFmpeg's API.
In mp_image_to_av_frame(), change the too-fragile
*new_ref = (struct mp_image){0};
into explicitly zeroing out the fields that are "transferred" to the
created AVFrame.

It seems this will be useful for Rokchip DRM hwcontext integration.
DRM hwcontexts have additional internal structure which can be different
depending on the decoder, and which is not part of the generic hwcontext
API. Rockchip has 1 layer, which EGL interop happens to translate to a
RGB texture, while VAAPI (mapped as DRM hwcontext) will use multiple
layers. Both will use sw_format=nv12, and thus are indistinguishable on
the mp_image_params level. But this is needed to initialize the EGL
mapping and the vo_gpu video renderer correctly.
We hope that the layer count is enough to tell whether EGL will
translate the data to a RGB texture (vs. 2 texture resembling raw nv12
data). For that we introduce MP_IMAGE_HW_FLAG_OPAQUE.
This commit adds the flag, infrastructure to set it, and an "example"
for D3D11.
The D3D11 addition is quite useless at this point. But later we want to
get rid of d3d11_update_image_attribs() anyway, while we still need a
way to force d3d11vpp filter insertion, so maybe it has some
justification (who knows). In any case it makes testing this easier.
Obviously it also adds some basic support for triggering the opaque
format for decoding, which will use a driver-specific format, but which
is not supported in shaders. The opaque flag is not used to determine
whether d3d11vpp needs to be inserted, though.
|
|

Mostly an obscure option for testing. But --videotoolbox-format can be
deprecated, as it becomes redundant.
We rely on the libavutil hwcontext implementation to reject invalid
pixfmts, or not to blow up if they are incompatible.

iive agreed to relicense things that are still in mpv to LGPLv2.1. So
change the licenses of the affected files, and rename the configure
switch for LGPL mode to --enable-preliminary-lgpl2.
(The "preliminary" part will probably be removed from the configure
switch soon as well.)
Also player/main.c hasn't had GPL parts since a few commits ago.

This restores cuda/cuvid under Windows.
Cuvid is relatively useless under Windows, but this was requested.
|

|

Like as in previous commits, you need a very recent FFmpeg (probably git
master).
|
|
|
|
|
|
|
|
|
| |
Now you need FFmpeg git, or something.
This also gets rid of the last real use of gpu_memcpy(). libavutil does
that itself. (vaapi.c still used it, but it was essentially unused,
because the code path isn't really in use anymore. It wasn't even
included due to the d3d-hwaccel dependency in wscript.)
|
|
|
|
| |
Just use FFmpeg 3.3 (or whatever it was) to get Cuvid support.

This changes the remaining "almost LGPL" files to LGPL, because we think
that the conditions the author set for these was finally fulfilled.

This reverts commit 96462040ec79b353457b64949f96fad30bd6e988.
I guess the autoprobing is still too primitive to handle this well. What
it really should be trying is initializing the wrapper decoder, and if
that doesn't work, try another method. This is complicated by hwaccels
initializing in a delayed way, so there is no easy solution yet.
Probably fixes #4865.
|
|
|
|
|
| |
This aims at making --opengl-hwdec-interop=cuda --hwdec=yes select the
correct decoding mode: cuda instead of vdpau-copy.
|
|
|
|
|
|
| |
Like in commit bd356333c713, but for the other hwaccels as well.
Fixes #4794.
|
|
|
|
|
|
| |
Not resetting hwdec_request_reinit caused it to flush on every packet,
which not only caused it to fail triggering the actual fallback, and let
it never decode a new frame, but also to get stuck on EOF.

This adds handling of spherical video metadata: retrieving it from
demux_lavf and demux_mkv, passing it through filters, and adjusting it
with vf_format. This does not include support for rendering this type of
video.
We don't expect we need/want to support the other projection types like
cube maps, so we don't include that for now. They can be added later as
needed.
Also raise the maximum sizes of stringified image params, since they
can get really long.

Apparently this was broken by the "ctx->hwdec" check in the if condition
guarding the destroy call, and "ctx->hwdec = NULL;" was moved up
earlier, making this always dead code.
This should probably be refcounted or so, although that could make it
worse as well. For now, add a flag whether the device should be
destroyed.
Fixes #4735.
|
|

Since these need to be refcounted, we throw them directly into struct
mp_image instead of being part of mp_colorspace. Even though they would
semantically make more sense in mp_colorspace, having them there is
really awkward because mp_colorspace is passed around and stored a lot,
and this way their lifetime is exactly tied to the lifetime of the
mp_image associated with it.

Can be enabled via --vd-lavc-dr=yes. See manpage additions for what it
does.
This reminds of the MPlayer -dr flag, but the implementation is
completely different. It's the same basic concept: letting the decoder
render into a GPU buffer to avoid a copy. Unlike MPlayer, this doesn't
try to go through filters (libavfilter doesn't support this anyway).
Unless a filter can work in-place, DR will be silently disabled. MPlayer
had very complex semantics about buffer types and management (which
apparently nobody ever understood) and weird restrictions that mostly
limited it to mpeg2 style codecs. The mpv code does not do any of this,
and just lets the decoder allocate an arbitrary number of untyped
images. (No MPlayer code was used.)
Parts of the code based on work by atomnuker (starting point for the
generic code) and haasn (some GL definitions, some basic PBO code, and
correct fencing).
|
|
|
|
|
|
|

Remove this code because it could be argued that it contains GPL-only
code (see commit 642e963c860 for details).
The remaining aspect methods appear to work just as well, are
potentially more compatible to other players, and the code becomes much
simpler.

Commit d5702d3b95 messed up the order of destruction of the elements: it
destroyed the avctx before the hwaccel uninit, even though the hwaccel
uninit could access avctx. This could happen with some old hwaccels
only, such as D3D ones before the new libavcodec hwaccel API.
Fix this by making use of the fact that avcodec_flush_buffers() will
uninit the underlying hwaccel. Thus we can be sure avctx is not using
any hwaccel objects anymore, and it's safe to uninit the hwaccel.
Move the hwdec_dev dstruction code with it, because otherwise we would
in theory potentially create some dangling pointers in avctx.
|
|
|
|
|
| |
Instead of various ad-hoc ways to achieve the same thing. (The API was
added only later.)
|
|
|
|
|
| |
Seems like AV_HWACCEL_FLAG_IGNORE_LEVEL was introduced much earlier than
AVCodecContext.hwaccel_flags.
|
|
|
|
| |
Was used by old hwaccel implementations.
|
|
|
|
|
|
|
| |
This sets AV_HWACCEL_FLAG_ALLOW_PROFILE_MISMATCH, which some hwaccels
using the new generic API respect. These do profile selection in
libavcodec, so it can be controlled only with an external flag, instead
of in mpv code like it used to be done.

They have been deprecated for a decade, yet you're forced to explicitly
deal with them at every step, or they will break your shit.
FFmpeg insists on keeping them, because libavfilter is too stupid to
deal with color ranges properly. Ridiculous.

This partially reverts the change from a longer time ago to always build
DXVA2 and D3D11VA together.
To make it simpler, we change the following:
- building with ANGLE headers is now required to build D3D hwaccels
- if DXVA2 is enabled, D3D11VA is still forcibly built
- the CLI vo_opengl ANGLE backend is now under --egl-angle-win32
This is done to reduce the dependency mess slightly.

MaxCLL is the more authoritative source for the metadata we are
interested in. The use of mastering metadata is sort of a hack anyway,
since there's no clearly-defined relationship between the mastering peak
brightness and the actual content. (Unlike MaxCLL, which is an explicit
relationship)
Also move the parameter fixing to `fix_image_params`
I don't know if the avutil check is strictly necessary but I've included
it anyway to be on the safe side.

List of changes:
1. Kill nom_peak, since it's a pointless non-field that stores nothing
of value and is _always_ derived from ref_white anyway.
2. Kill ref_white/--target-brightness, because the only case it really
existed for (PQ) actually doesn't need to be this general: According
to ITU-R BT.2100, PQ *always* assumes a reference monitor with a
white point of 100 cd/m².
3. Improve documentation and comments surrounding this stuff.
4. Clean up some of the code in general. Move stuff where it belongs.
