This adds API to libmpv that lets host applications use the mpv opengl renderer. This is a more flexible (and possibly more portable) option to foreign window embedding (via --wid). This assumes that methods like context sharing and multithreaded OpenGL rendering are infeasible, and that a way is needed to integrate it with an application that uses a single thread to render everything. Add an example that does this with QtQuick/qml. The example is relatively lazy, but still shows how relatively simple the integration is. The FBO indirection could probably be avoided, but would require more work (and would probably lead to worse QtQuick integration, because it would have to ignore transformations like rotation). Because this makes mpv directly use the host application's OpenGL context, there is no platform specific code involved in mpv, except for hw decoding interop. main.qml is derived from some Qt example. The following things are still missing: - a way to do better video timing - expose GL renderer options, allow changing them at runtime - support for color equalizer controls - support for screenshots

Introduction
|
|
============
|
|
|
|
This file lists all changes that can cause compatibility issues when using
|
|
mpv through the client API (libmpv and ``client.h``). Since the client API
|
|
interfaces to input handling (commands, properties) as well as command line
|
|
options, this list is interesting for other uses of mpv, such as the Lua
|
|
scripting interface, key bindings in ``input.rst``, or plain command line
|
|
usage.
|
|
|
|
Normally, changes to the C API that are incompatible to previous iterations
|
|
receive a major version bump (i.e. the first version number is increased),
|
|
while C API additions bump the minor version (i.e. the second number is
|
|
increased). Changes to properties/commands/options may also lead to a minor
|
|
version bump, in particular if they are incompatible.
|
|
|
|
The version number is the same as used for MPV_CLIENT_API_VERSION (see
|
|
``client.h`` how to convert between major/minor version numbers and the flat
|
|
32 bit integer).
|
|
|
|
Also, read the section ``Compatibility`` in ``client.h``.

API changes
|
|
===========
|
|
|
|
::
|
|
|
|
1.11 - add OpenGL rendering interop API - allows an application to combine
|
|
its own and mpv's OpenGL rendering
|
|
Warning: this API is not stable yet - anything in opengl_cb.h might
|
|
be changed in completely incompatible ways in minor API bumps
|
|
--- mpv 0.7.0 is released ---
|
|
1.10 - deprecate/disable everything directly related to script_dispatch
|
|
(most likely affects nobody)
|
|
1.9 - add enum mpv_end_file_reason for mpv_event_end_file.reason
|
|
- add MPV_END_FILE_REASON_ERROR and the mpv_event_end_file.error field
|
|
for slightly better error reporting on playback failure
|
|
- add --stop-playback-on-init-failure option, and make it the default
|
|
behavior for libmpv only
|
|
- add qthelper.hpp set_option_variant()
|
|
- mark the following events as deprecated:
|
|
MPV_EVENT_TRACKS_CHANGED
|
|
MPV_EVENT_TRACK_SWITCHED
|
|
MPV_EVENT_PAUSE
|
|
MPV_EVENT_UNPAUSE
|
|
MPV_EVENT_METADATA_UPDATE
|
|
MPV_EVENT_CHAPTER_CHANGE
|
|
They are handled better with mpv_observe_property() as mentioned in
|
|
the documentation comments. They are not removed and still work.
|
|
1.8 - add qthelper.hpp
|
|
1.7 - add mpv_command_node(), mpv_command_node_async()
|
|
1.6 - modify "core-idle" property behavior
|
|
- MPV_EVENT_LOG_MESSAGE now always sends complete lines
|
|
- introduce numeric log levels (mpv_log_level)
|
|
--- mpv 0.6.0 is released ---
|
|
1.5 - change in X11 and "--wid" behavior again. The previous change didn't
|
|
work as expected, and now the behavior can be explicitly controlled
|
|
with the "input-x11-keyboard" option. This is only a temporary
|
|
measure until XEmbed is implemented and confirmed working.
|
|
Note: in 1.6, "input-x11-keyboard" was renamed to "input-vo-keyboard",
|
|
although the old option name still works.
|
|
1.4 - subtle change in X11 and "--wid" behavior
|
|
(this change was added to 0.5.2, and broke some things, see #1090)
|
|
--- mpv 0.5.0 is released ---
|
|
1.3 - add MPV_MAKE_VERSION()
|
|
1.2 - remove "stream-time-pos" property (no replacement)
|
|
1.1 - remap dvdnav:// to dvd://
|
|
- add "--cache-file", "--cache-file-size"
|
|
- add "--colormatrix-primaries" (and property)
|
|
- add "primaries" sub-field to image format properties
|
|
- add "playback-time" property
|
|
- extend the "--start" option; a leading "+", which was previously
|
|
insignificant is now significant
|
|
- add "cache-free" and "cache-used" properties
|
|
- OSX: the "coreaudio" AO spdif code is split into a separate AO
|
|
--- mpv 0.4.0 is released ---
|
|
1.0 - the API is declared stable
|
