While most Wayland compositors provide a socket path indicated by
environment variable WAYLAND_DISPLAY, others may sometimes bequeath a
socket file descriptor specified by WAYLAND_SOCKET.
mpv has too many commands and they are unorganized in the
documentation, making it difficult to navigate.
This commit completely reorganizes the commands into several
categories to make the documentation easier to navigate.
The following categories are defined:
- Playback Control: Seeking and stepping.
- Property Manipulation: Changing property values.
- Playlist Manipulation: Playlist navigation and editing.
- Track Manipulation: Track navigation and editing.
- Text Manipulation: Text printing, expansion, escaping.
- Configuration: General configuration and related files.
- OSD: Displaying contents as OSD.
- Input and Keybind: Input configuration and key bindings.
- Execution: Execution of mpv and subprocesses.
- Scripting: Script loading and communication.
- Screenshot: Taking screenshots.
- Filter: Changing filters.
- Miscellaneous: Other commands.
If the playlist is loaded directly from a protocol like memory://, the
playlist_path represents the entire playlist. In cases where we have a
large playlist, this results in the entire playlist being duplicated for
each item. For example, if the input size is 300 kB with 10k items, we
end up using 3 GB of memory just to store the playlist_path strings.
With --osd-border-style=opaque-box and background-box, respect
--osd-shadow-offset.
I am not sure if --osd-shadow-offset should be inherited with
--osd-border-style=outline-and-shadow, especially since it doesn't let
you specify different x and y offsets.
The current OSD font size is excessively large, causing most
messages—except for very short ones to overflow horizontally.
I conducted testing across multiple devices of varying screen sizes and
under different scenarios. The adjusted font size strikes a good balance
for readability on non-high-DPI displays, while high-DPI displays should
utilize DPI scaling as needed.
Additionally, I compared the font sizes of subtitles and UI elements
across various VOD platforms, which generally use smaller font in most
cases.
The current sub font size was significantly larger than even PGS
subtitles, which are quite large on their own. Now, they are comparable.
The subtitle font size was chosen based on recommendations from the BBC
Subtitle Guidelines. It is set to 8% of the video height with a
recommended scaling factor of 0.67. Therefore, at 720p (the reference
size for mpv font scaling), the calculation is 8% * 0.67 * 720 = 38.592,
rounded down to 38. This value falls within the recommended scaling
range of x0.5–x1 for desktop PCs/Laptops and TVs (32"–42"). For more
information, see
https://www.bbc.co.uk/accessibility/forproducts/guides/subtitles/#Presentation-font-size.
OSD font size is smaller than font as those elements shouldn't be
distractful and only noticable when the user wants to look at them.
Outline size is set to 5.5% of font size.
--input-cmdlist crops playlist-next-playlist, playlist-prev-playlist,
write-watch-later-config and delete-watch-later-config, so increase the
string length to that of the longest command.
Also stop specifying both the minimum and maximum length since they are
the same.
It already prints %, so there's no need for '/100'. Also, use the print
helper while at it.
6ea08be59a added a percent sign but didn't
remove '/100', so we ended up with both, which is redundant.
Allowing arbitrary command execution for the fuzzer is not ideal. While
some testing of this code is valid, unsupervised fuzzing of the input is
not. It may be better to add a dedicated test or fuzz-test for this
case.
82231fd74d mentioned that for the "rot"
transform flip=true must be set, which "makes no sense at all".
The reason this is happening is that the rotation matrix calculation
is only valid for the 2D coordinate system where y axis is 90 degrees
counterclockwise from x axis, but the coordinate system of chroma
offset has its origin at top-left so it is the opposite, which results
in the rotation going to the opposite way. Setting flip=true fixes the
rotation direction, but results in a flipped y coordinate.
Fix this by reversing the rotation angle for chroma offset rotation
matrix calculation. This also allows removing some duplicated code.
High --osd-blur values break the osd-bar by not drawing the filled
portion, and even low values just make it look worse, so don't apply
--osd-blur to the osd-bar.
Most of the commands list here are several years old and we will
probably never change them. And it is already stated in the description
of individual commands if they are deprecated or subject to change.
Furthermore, it is easy to add new commands at the end of this section
by accident. I added load-config-file and load-input-conf here without
realizing it's a separate section, and I assume this was also the case
for begin-vo-dragging.
The detailed issue is here:
#15212
problem: Since The AudioTrack is not an mpv instance level but a global object, it cannot support multiple mpv instances at the same time. For example, if you create two instances and then destroy one of them, the other instance may crash.
Add jni usage count to fix this.
Currently it asks which version introduced the problem, but
users are unlikely to know if they don't update and test every
single version released, and this field is rarely filled in
practice by non-developers.
On the other hand, it's much easier to recall the last working
version that they have used before.
So ask for the last known working version, which is useful
information for developers to narrow down bisecting range.
Also ask when did the issue start in general since the issue
can be caused by system or driver updates.
Observing playlist property with "native" type is too expensive for
larger playlists, and we only observe this property to
activate/deactivate next/prev buttons on the osc. We actually only need
to know if the playlist-count has changed, nothing else.
