The intention of M_OPT_FIXED is to make options not runtime-changeable,
so trying to set them at runtime will always error. This is not wanted
for --profile and --include, for which there is no reason to block them
at runtime.
Fixes#3581.
When switching a subtitle track, the subtitle wasn't necessarily
updated, especially when playback was paused.
Some awfully subtle and complex interactions here.
First off (and not so subtle), the subtitle decoder will read packets
only on explicit update_subtitles() calls, which, if video is active, is
called only when a new video frame is shown. (A simply video frame
redraw doesn't trigger this.) So call it explicitly. But only if
playback is "initialized", i.e. not when it does initial track selection
and decoder init, during which no packets should be read.
The second issue is that the demuxer thread simply will not read new
packets just because a track was switched, especially if playback is
paused. That's fine, but if a refresh seek is to be done, it really
should do this. So if there's either 1. a refresh seek requested, or 2.
a refresh seek ongoing, then read more packets.
Note that it's entirely possible that we overflow the packet queue with
this in unpredicated weird corner cases, but the queue limit will still
be enforced, so this shouldn't make the situation worse.
This was dumb and could return something like "{name=123}" as an array.
Also, fix the error message if a key is not a string. lua_typename()
takes a type directly, not a stack item.
The last commit was fine - just making some enhancements.
Rename the function to parse_node_chapters(), since it really has not
much to do with Lua.
Don't use len<0 as check whether it makes sense to set chapters, and
instead check for mpctx->demuxer (that includes the possibility to set
chapters e.g. within a preload hook, but after chapters are initialized
from the demuxer).
Return M_PROPERTY_ERROR instead of M_PROPERTY_OK if the mpv_node has the
wrong type.
It's ok if a chapter has no title, so change the checks accordingly.
Remove a Yoda condition.
Notify that chapter metadata might have changed with mp_notify() (the
chapter list itself is already taken care by generic code).
Fix leaking the metadata allocations of the new chapter list.
Obviously, in the vast majority of cases, there's only one device
in the system, but doing this means we're more likely to get a
usable device in the multi-device case.
cuda would support decoding on one device and displaying on another
but the peer memory handling is not transparent and I have no way
to test it so I can't really write it.
The documentation around this stuff is poor, but I found an nvidia
sample that demonstrates how to use the interop API most efficiently.
(https://github.com/nvpro-samples/gl_cuda_interop_pingpong_st)
Key lessons are:
1) you can register the texture itself and have cuda write to it,
thereby skipping an additional copy through the PBO.
2) You don't have to be mapped when you do the copy - once you get a
mapped pointer, it remains valid. Magic!
This lets us throw out the PBOs as well as much of the explicit
alignment and stride handling.
CPU usage is slightly (~3%) lower for 4K content in one test case,
so it makes a detectable difference, and presumably saves memory.
Seems like this confused users quite often.
Instead of --profile=pseudo-gui, --player-operation-mode=pseudo-gui now
has to be used to invoke pseudo GUI mode. The old way still works, and
still behaves in the old way.
I would have been fine with this, but now I want to add another flag,
and the duplication would become more messy than having a strange
function for deduplication.
The property observation mechanism turns properties into integer IDs for
fast comparison. This means if two properties get the same ID, they will
receive the same notifications. Use this to make properties under
options/ receive notifications. The option-property bridge marks
top-level properties with the same name as the options.
This still might not work in cases the C code sets values on options
structs directly.
On x11, you can change the fullscreen via the window manager and without
mpv's involvement. In these cases, the internal fullscreen flag has to
be updated.
The hack used for this didn't really work properly. Change it
accordingly. The important thing is that the shadow copy of the option
is updated. This is still not really ideal.
Fixes#3570.
The documentation claims that --video-unscaled will still perform
anamorphic adjustments, and it rightfully should. The current reality is
that it does not, because the video-unscaled size was based on the wrong
set of variables. (encoded width/height instead of nominal display
width/height)
If one of the audio output format options is set, brually reinit the
audio chain.
Since the audio-channels property is still mapped to the deprecated
read-only property, "options/audio-channels" currently has to be used,
e.g. "cycle-values options/audio-channels 2 7.1".
The intention is to give libmpv users as much flexibility to load
scripts as using mpv from CLI, but without restricting libmpv users from
having to decide everything on creation time, or having to go through
hacks like recreating the libmpv context to update state.
Basically, make use of all the new code.
Unfortunately, the new code and it's "compromise semantics" with the old
behavior before the options/properties merge bites back: this
vid/aid/sid, deinterlace, and video-aspect properties have neutral
default settings (such as "auto"), but return the current value during
playback, so we would unnecessarily force this value when playback is
resumed. So leave those as they are.
Also, the colormatrix options were removed a long time ago.
Add this flag where needed. You shouldn't be able to set e.g. config-dir
in these situations.
Remove the mpctx->initialized check from the property/option bridge,
since it's in use strictly only after initialization. Likewise, the
apply-profile command doesn't need to check this.
When we rotate the inmage by 90° or 270°, chroma width and height need
to be swapped.
Fixes#3568.
But is the chroma sub location correct? Who the hell knows...
With the merging of options and properties, the mpv_set_option()
function is close to being useless, and mpv_set_property() can be used
for everything instead. There are certain conflicts remaining, which are
explained in depth in the docs. For now, none of this should affect
existing code using the client API.
Make mpv_set_property() redirect to mpv_set_option() before
initialization.
Remove some options marked as M_OPT_FIXED. The "pause" and "speed"
options cannot be written anymore without the playloop being notified by
it, so the M_OPT_FIXED does nothing. For "vo-mmcss-profile", the problem
was lack of synchronization, which has been added. I'm not sure what the
problem was with "frames" - I think it was only marked as M_OPT_FIXED
because changing it during playback will have no effect. Except for
pause/speed, these changes are needed to make them writable as
properties after mpv_initialize().
Also replace all remaining uses of CONF_GLOBAL with M_OPT_FIXED.
mp_new_client() blatantly accessed some mutex-protected state outside of
the mutex.
The destruction code is in theory OK, but with changes in the following
commits it'll be a bit hard to guarantee that it stays this way. Add a
simple flag that makes adding new clients impossible, so that having no
clients after shutdown_clients() remains guaranteed.
Instead of rechecking the timers every time after an event is read, do
it only once the event queue is empty. This is probably slightly more
efficient, and facilitates the next commit.
This is the actual decoder output, with no overrides applied. (Maybe
video-params shouldn't contain the overrides in the first place, but
damage done.)
This really shouldn't be in vd_lavc.c - move it to dec_video.c, where it
also applies aspect overrides. This makes all overrides in one place.
The previous commit contains some required changes for resetting the
image parameters change detection (i.e. it's not done only on video
aspect override changes).
Use the new mechanism, instead of wrapped properties. As usual, extend
the update handling to some options that were forgotten/neglected
before. Rename video_reset_aspect() to video_reset_params() to make it
more "general" (and we can amazingly include write access to
video-aspect as well in this).
A recent change merged the window-scaler option and property, but forgot
that the option is float for some reason, while the property uses
double. This led to undefined behavior. Fix it by changing the option
to double too.
Setting the osc or ytdl properties will now load/unload the associated
scripts. (For ytdl this does not mean the currently played URL will be
reloaded.)
Also add a changelog entry for this, which also covers the preceding
work for --terminal.
Remove wrapper properties for OSD and video position updates, use the
new mechanism for them. We can mark the options directly. Update
behavior will work for more options (since I've casually marked more
affected options than the old less direct mechanism covered).
