There's literally no reason why these functions have to be inline (they
might be performance critical, but then the function call overhead isn't
going to matter at all).
Uninline them and move them to mp_image.c. Drop the header file and fix
all uses of it.

Just so that it has the same indentation as the extremely similar audio
filter output.

Remove the confusing crap that allowed a filter using the libavfilter
bridge to be compiled without libavfilter. Instead, compile the wrappers
only if libavfilter is enabled at compile time.
The only filter which still requires it is vf_stereo3d (unfortunately).
Special-case this one. (The whole filter and how it interacts with lavfi
is pure braindeath anyway.)

This was apparently useful for correct interlaced scaling (although I
don't know anyone who used this). It was rarely used (if at all), had an
inconvenient output format (packed YUV), and now has a better solution
in libavfilter (using the libavfilter "scale" filter via vf_lavfi).
There is no reason to keep this filter any longer.
|
| |
|
|
|
| |
Better solutions are available in vf_vapoursynth and vf_lavfi. The only
user I know who used this is now using vf_vapoursynth.
|
| |
|
|
| |
If you really want it, it's in libavfilter and can be used via vf_lavfi.
|

It's entirely useless. I left it in for a while, because the analog TV
code had a transitional bug that could switch chroma planes, but it was
fixed long ago. It's also available in libavfilter.

Apparently it was completely broken and essentially did nothing. This
was broken sometime in early mpv or mplayer2 times.
Get rid of it. If you _really_ need it, wait until FFmpeg ports it from
MPlayer, which will happen very soon.

And remove all uses of the VFCAP_CSP_SUPPORTED* constants. This is
supposed to reduce conversions if many filters are used (with many
incompatible pixel formats), and also for preferring the VO's natively
supported pixel formats (as opposed to conversion).
This is worthless by now. Not only do the main VOs not use software
conversion, but also the way vf_lavfi and libavfilter work mostly break
the way the old MPlayer mechanism worked. Other important filters like
vf_vapoursynth do not support "proper" format negotation either.
Part of this was already removed with the vf_scale cleanup from today.
While I'm touching every single VO, also fix the query_format argument
(it's not a FourCC anymore).

Well, probably still not very good, but now at least accounts for the
case the decoder or a filter outputs nonsense values.

Most of this is explained in the code comments. This change should
improve performance with vapoursynth, especially if concurrent requests
are used.
This should change nothing if vf_vapoursynth is not in the filter chain,
since non-threaded filters obviously can not asynchronously finish
filtering of frames.

If a filter exists, but has no metadata, just return success. This
allows the user to distinguish between no metadata available, and filter
not inserted.
See #1408.

This input command crashed:
vf add @mf:format=yuv420p ; show_text "${vf-metadata/mf}"
Fixes #1408.

This is an ancient filter, and we assume it's not useful anymore.
If you really want this, it's still available in libavfilter (e.g. via
--vf=lavfi=[pp...]). The disadvantage is that mpv doesn't pass through
QP information to libavfilter. (This was probably the reason vf_pp still
was part of mpv - it was slightly easier to pass QP internally.)

Remove the extra vf_chain.output field - there's absolutely no need for
it, because there is always a last filter which will buffer the output.
For some reason, vf_chain.last was never set, which we now need to fix
too.

Consider a filter which turns 1 frame into 2 frames (such as an
deinterlacer). Until now, we forced filters to produce all output frames
at once. This was done for simplicity.
Change the filter API such that a filter can produce frames
incrementally.
|

|

| |
Mostly useful for debugging.

The final goal is all mp_msg calls produce complete lines. We want this
because otherwise, race conditions could corrupt the terminal output,
and it's inconvenient for the client API too. This commit works towards
this goal. There's still code that has this not fixed yet, though.
|

The type is struct mp_image_params, so the "params" should have a "s".
"equals" shouldn't, because it's plural for 2 params. Important.

Make sure every video filter has valid parameters for input and output.
(This also ensures we don't take possibly invalid decoder output, or
feed invalid decodr/filter output to VOs.)
Also, the updated image size check now (almost) works like the
corresponding check in FFmpeg.

Until now, failure to allocate image data resulted in a crash (i.e.
abort() was called). This was intentional, because it's pretty silly to
degrade playback, and in almost all situations, the OOM will probably
kill you anyway. (And then there's the standard Linux overcommit
behavior, which also will kill you at some point.)
But I changed my opinion, so here we go. This change does not affect
_all_ memory allocations, just image data. Now in most failure cases,
the output will just be skipped. For video filters, this coincidentally
means that failure is treated as EOF (because the playback core assumes
EOF if nothing comes out of the video filter chain). In other
situations, output might be in some way degraded, like skipping frames,
not scaling OSD, and such.

Additionally to removing the global variables, this makes the options
more uniform. --ssf-... becomes --sws-..., and --sws becomes --sws-
scaler. For --sws-scaler, use choices instead of magic integer values.

Now the video filter code handles these explicitly, which should
increase robustness (or at least find bugs earlier).

vf_fix_img_params() takes care of overwriting image parameters that are
normally not set correctly by filters. But this makes no sense for input
images. So instead, check that the input is correct.
It still has to be done for the first input image, because that's used
to handle some overrides (see video_reconfig_filters()).

These replace vf_read_output_frame(), although we still emulate that
function. This change is preparation for another commit (and this is
basically just to reduce the diff and signal/noise ratio in that
commit).
|

|
|

Preparation (and simplification) for following commits.
|
| |
|

Nota that this flag is not set for other auto-inserted filters (like
deinterlacing or rotation).

This factors out some code from vo_vdpau.c, especially deinterlacing
handling. The intention is to use this for vo_vdpau.c to make the logic
significantly easier, and to use it for vo_opengl (gl_hwdec_vdpau.c) to
allow selecting deinterlace and postprocessing modes.
As of this commit, the filter actually does nothing, since both vo_vdpau
and vo_opengl treat the generated images as normal vdpau images. This
will change in the following commits.

The filters don't always print an error on their own, and printing an
error is better than silently dropping the frame.

Or in other words, add support for properly draining remaining frames
from video filters. vf_yadif is buffering at least one frame, and the
buffered frame was not retrieved on EOF.
For most filters, ignore this for now, and just adjust them to the
changed semantics of filter_ext. But for vf_lavfi (used by vf_yadif),
real support is implemented. libavfilter handles this simply by passing
a NULL frame to av_buffersrc_add_frame(), so we just have to make
mp_to_av() handle NULL arguments.
In load_next_vo_frame(), we first try to output a frame buffered in the
VO, then the filter, and then (if EOF is reached and there's still no
new frame) the VO again, with draining enabled. I guess this was
implemented slightly incorrectly before, because the filter chain still
could have had remaining output frames.

When using rotation with hw decoding, and the VO does not support
rotation, vf_rotate is attempted to be inserted. This will go wrong, and
after that it can't recover because a vf_scale filter was autoinserted.
Just removing all autoinserted filters before reconfig fixes this.
|

Minor cleanup, so that we can stuff more information into
mp_image_params later.

Mainly meant to apply simple VapourSynth filters to video at runtime.
This has various restrictions, which are listed in the manpage.
Additionally, this actually copies video frames when converting frame
references from mpv to VapourSynth, and a second time when going from
VapourSynth to mpv. This is inefficient and could probably be easily
improved. But for now, this is simpler, and in fact I'm not sure if
we even can references VapourSynth frames after the core has been
destroyed.

This is all not needed anymore. In particular, remove all configure
switches except --enable-libavfilter.
|

Small errors are unavoidable, but truncation can cause anamorphic video
to be off by 1 or 2 pixels.

Same for companion functions.

Always pass around mp_log contexts in the option parser code. This of
course affects all users of this API as well.
In stream.c, pass a mp_null_log, because we can't do it properly yet.
This will be fixed later.

Since m_option.h and options.h are extremely often included, a lot of
files have to be changed.
Moving path.c/h to options/ is a bit questionable, but since this is
mainly about access to config files (which are also handled in
options/), it's probably ok.

The tmsg stuff was for the internal gettext() based translation system,
which nobody ever attempted to use and thus was removed. mp_gtext() and
set_osd_tmsg() were also for this.
mp_dbg was once enabled in debug mode only, but since we have log level
for enabling debug messages, it seems utterly useless.

This gets rid of the vf_vo pseudo-filter. It ends the idea of MPlayer's
architecture that the VO is just a (terminating) video filter. It didn't
really work for us with respect to video timing (the "end" of the video
chain isn't really made for video timing, and making it do so would be
awkward), and now we're removing it entirely. We will be able to fix
some things, such as properly draining video on reconfiguration.
