Now that we have identified the device types associated with each hwdec, we
can take advantage of this to ensure that get the right hwdec is chosen when
decoding frames and there are multiple choices available with different device
types.
This is also plumbed into the filter initialisation logic, although in practice
the decision on the hwdec has already been made at this point - still it's
easier than retaining the ambiguous look up logic and worrying that it might
lead to an inconsistent result.
VapourSynth introduced their version 4 API in R55, 3 years ago. mpv is
still using the deprecated version 3. I think it is good to migrate
before VapourSynth completely removes it.
The most impacted area is the video format. Previously we have a fixed
table of supported formats, each represented by an integer. In v4, the
integer is replaced by pointer to the full struct of the format.
Second, the way to create video filter is changed. Previously caller
needs to supply a "initialization" callback to `createFilter()`, which
sets up video info etc. In v4, video info is prepared first, passed to
the `createVideoFilter2()` and we get back the node.
Also, previously mpv was using the `fmSerial` filter mode, which means
VapourSynth 1) can only request one frame from mpv at a time, and 2) the
order of frames requested must be sequential. I propose to change it to
the parallel request mode, which requests multiple frames at a time in
semi random order. The reasons are, for 1), the get frame function,
`infiltGetFrame()`, unlocks the mutex during output image generation,
thus can benefit from parallel requests. For 2) thanks to the frame
buffer, unordered frame requests are acceptable. Just make sure the
buffer is large enough.
Third, the way VapourSynth scripting environment works change. In v4,
the scripting API is operated through struct pointer, much like the
exist `vsapi` pointer. The "finalize" function is also no longer needed.
Currently the vapoursynth video filter does not accept any argument for
passing arbitrary user data. This limits what the VS script can do.
Ideally, the vapoursynth filter has an user-data parameter that contain
string value. mpv passes that value to the VS script just like
container_fps and others. Once the VS script gets the data, it can do
all sorts of data extraction and transformation.
Another benefit is that instead of mpv always have to catch up to user
needs for this filter, with this users can just pass whatever needed
themselves, thus becomes more future-proof.
Fixes#14214
This might not always be correct depending on filtering done in VS. But
unless VS send us all the metadata we have to get it from somewhere.
Fixes dynamic frame metadata, which was copied from fmt_in, initialized
only upon reinitialization.
Fixes crashes caused by the use of stale pointers.

Abstract out EGL, and allow choosing between EGL and vulkan at runtime.
vf_gpu_egl.c contains GL specific context and creation/destroy code,
vf_gpu_vulkan.c contains Vulkan specific. This allows vf_gpu being
built in systems where EGL is not available and where Vulkan is
available.
refqueue gets the field of the frame from mp_image which almost always(if not
always) assumes bottom field order first. By default this behavior should not
change but specifying the field order should bypass this.
Previously there was no way to specify the field order of interlaced videos
when deinterlacing with inbuilt filters. Lavfi deinterlacers seemed to prefer
top field order while inbuilt ones (vdpaupp, vavpp, d3d11vpp) seemed to prefer
bottom field order. The default "auto" option should work exactly as before
while specifying either "tff" or "bff" should force the specified field order
We prefer to fail fast rather than degrade in unpredictable ways.
The example in sub/ is particularly egregious because the code just
skips the work it's meant to do when an allocation fails.
This commit replaces all uses of sig_peak and maps all HDR metadata.
Form notable changes mixed usage of maxCLL and max_luma is resolved and
not always max_luma is used which makes vo_gpu and vo_gpu_next behave
the same way.
Vapoursynth does not provide crop metadata and input one is likely to be
invalidated during filtering. Set crop to full frame if image dimensions
were changed during filtering.
Fixes: #12780
We've got an ungodly amount of OPT_REPLACED and OPT_REMOVED sitting
around in the code. This is harmless, but the vast majority of these are
ancient. 26f4f18c06 is the last commit
that touched the majority of these and of course that only changed how
options were declared so all of this stuff was deprecated even before
that. No use in keeping these, so just delete them all. As an aside,
there was actually a cocoa_opts but it had only a single option which
was replaced by something else and empty otherwise. So that entire thing
was just simply removed. OPT_REPLACED/OPT_REMOVED declarations that were
added in 0.35 or later were kept as is.
mpv has a generic method for getting the display resolution, so we can
save it in vf_vapoursynth without too much trouble. Unfortunately, the
resolution won't actually be available in many cases (like my own)
because the windowing backend doesn't actually know it yet. It looks
like at least windows always returns the default monitor (maybe we
should do something similar for x11 and wayland), so there's at least
some value. Of course, this still has a bunch of pitfalls like not being
able to cope with multi monitor setups at all but so does display_fps.
As an aside, the vapoursynth API this uses apparently requires R26 (an
ancient version anyway), so bump the build to compensate for this.
Fixes#11510
this changes mp_image_new_ref() to handle allocation failure itself
instead of doing it at its many call-sites (some of which never checked
for failure at all).
also remove MP_HANDLE_OOM() from the call sites since this is not
necessary anymore.
not all the call-sites have been touched, since some of the caller might
be relying on `mp_image_new_ref(NULL)` returning NULL.

Although we can support vulkan multiplane images, cuda lacks any such
support, and so cannot natively import such images for interop. It's
possible that we can do separate exports for each plane in the image
and have it work, but for now, we can selectively disable multiplane
when we know that we'll be consuming cuda frames.
As a reminder, even though cuda is the frame source, interop is one way
so the vulkan images have to be imported to cuda before we copy the
frame contents over.
This logic here is slightly more complex than I'd like but you can't
just set the flag blindly, as it will cause hwframes ctx creation to
fail if the format is packed or if it's planar rgb. Oh well.
c784820454 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.
3a9e661e92 officially made this video
filter deprecated roughly 6 years ago. Every other video filter in that
commit has actually been removed since then except for vf_sub. ffmpeg
does have its own subtitles filter, but it doesn't have the same control
over scale like vf_sub does. That's probably why wm4 never actually
removed it. Let's stop scaring users with a warning since this filter
probably won't ever get removed. Closes#9254.
Today, lavfi filters are provided a hw_device from the first
hwdec_interop that was loaded, regardless of whether it's the right one
or not. In most situations where a hardware based filter is used, we
need more control over the device.
In this change, a `hwdec_interop` option is added to the lavfi wrapper
filter configuration and this is used to pick the correct hw_device to
inject into the filter or graph (in the case of a graph, all filters
get the same device).
Note that this requires the use of the explicit lavfi syntax to allow
for the extra configuration.
eg:
```
mpv --vf=hwupload
```
becomes
```
mpv --vf=lavfi=[hwupload]:hwdec_interop=cuda-nvdec
```
or
```
mpv --vf=lavfi-bridge=[hwupload]:hwdec_interop=cuda-nvdec
```
