The purpose of the new API is to make it useable with other APIs than OpenGL, especially D3D11 and vulkan. In theory it's now possible to support other vo_gpu backends, as well as backends that don't use the vo_gpu code at all. This also aims to get rid of the dumb mpv_get_sub_api() function. The life cycle of the new mpv_render_context is a bit different from mpv_opengl_cb_context, and you explicitly create/destroy the new context, instead of calling init/uninit on an object returned by mpv_get_sub_api(). In other to make the render API generic, it's annoyingly EGL style, and requires you to pass in API-specific objects to generic functions. This is to avoid explicit objects like the internal ra API has, because that sounds more complicated and annoying for an API that's supposed to never change. The opengl_cb API will continue to exist for a bit longer, but internally there are already a few tradeoffs, like reduced thread-safety. Mostly untested. Seems to work fine with mpc-qt.

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, you should also look at ``interface-changes.rst``.
|
|
|
|
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``.
|
|
|
|
Options, commands, properties
|
|
=============================
|
|
|
|
Changes to these are not listed here, but in ``interface-changes.rst``. (Before
|
|
client API version 1.17, they were listed here partially.)
|
|
|
|
This listing includes changes to the bare C API and behavior only, not what
|
|
you can access with them.
|
|
|
|
API changes
|
|
===========
|
|
|
|
::
|
|
|
|
--- mpv 0.29.0 ---
|
|
1.28 - deprecate the render opengl_cb API, and replace it with render.h
|
|
and render_gl.h. The goal is allowing support for APIs other than
|
|
OpenGL. The old API is emulated with the new API.
|
|
Likewise, the "opengl-cb" VO is renamed to "libmpv".
|
|
mpv_get_sub_api() is deprecated along the opengl_cb API.
|
|
The new API is relatively similar, but not the same. The rough
|
|
equivalents are:
|
|
mpv_opengl_cb_init_gl => mpv_render_context_create
|
|
mpv_opengl_cb_set_update_callback => mpv_render_context_set_update_callback
|
|
mpv_opengl_cb_draw => mpv_render_context_render
|
|
mpv_opengl_cb_report_flip => mpv_render_context_report_swap
|
|
mpv_opengl_cb_uninit_gl => mpv_render_context_free
|
|
The VO opengl-cb is also renamed to "libmpv".
|
|
1.27 - make opengl-cb the default VO. This causes a subtle behavior change
|
|
if the API user called mpv_opengl_cb_init_gl(), but does not set
|
|
the "vo" option. Before, it would still have used another VO (like
|
|
on the CLI, e.g. vo=gpu). Now it'll behave as if vo=opengl-cb was
|
|
used.
|
|
--- mpv 0.28.0 ---
|
|
1.26 - remove glMPGetNativeDisplay("drm") support
|
|
- add mpv_opengl_cb_window_pos and mpv_opengl_cb_drm_params and
|
|
support via glMPGetNativeDisplay() for using it
|
|
- make --stop-playback-on-init-failure=no the default in libmpv (just
|
|
like in mpv CLI)
|
|
--- mpv 0.27.0 ---
|
|
1.25 - remove setting "no-" options via mpv_set_option*(). (See corresponding
|
|
deprecation in 0.23.0.)
|
|
--- mpv 0.25.0 ---
|
|
1.24 - add a MPV_ENABLE_DEPRECATED preprocessor symbol, which can be defined
|
|
by the user to exclude deprecated API symbols from the C headers
|
|
--- mpv 0.23.0 ---
|
|
1.24 - the deprecated mpv_suspend() and mpv_resume() APIs now do nothing.
|
|
--- mpv 0.22.0 ---
|
|
1.23 - deprecate setting "no-" options via mpv_set_option*(). For example,
|
|
instead of "no-video=" you should set "video=no".
|
|
- do not override the SIGPIPE signal handler anymore. This was done as
|
|
workaround for the FFmpeg TLS code, which has been fixed long ago.
|
|
- deprecate mpv_suspend() and mpv_resume(). They will be stubbed out
|
|
in mpv 0.23.0.
|
|
- make mpv_set_property() work to some degree before mpv_initialize().
|
|
It can now be used instead of mpv_set_option().
|
|
- semi-deprecate mpv_set_option()/mpv_set_option_string(). You should
|
|
use mpv_set_property() instead. There are some deprecated properties
|
|
which conflict with some options (see client.h remarks on
|
|
mpv_set_option()), for which mpv_set_option() might still be required.
|
|
In future mpv releases, the conflicting deprecated options/properties
|
|
will be removed, and mpv_set_option() will internally translate API
|
|
calls to mpv_set_property().
|
|
- qthelper.hpp: deprecate get_property_variant, set_property_variant,
|
|
set_option_variant, command_variant, and replace them with
|
|
get_property, set_property, command.
|
|
--- mpv 0.19.0 ---
|
|
1.22 - add stream_cb API for custom protocols
|
|
--- mpv 0.18.1 ---
|
|
---- - remove "status" log level from mpv_request_log_messages() docs. This
|
|
is 100% equivalent to "v". The behavior is still the same, thus no
|
|
actual API change.
|
|
--- mpv 0.18.0 ---
|
|
1.21 - mpv_set_property() changes behavior with MPV_FORMAT_NODE. Before this
|
|
change it rejected mpv_nodes with format==MPV_FORMAT_STRING if the
|
|
property was not a string or did not have special mechanisms in place
|
|
the function failed. Now it always invokes the option string parser,
|
|
and mpv_node with a basic data type works exactly as if the function
|
|
is invoked with that type directly. This new behavior is equivalent
|
|
to mpv_set_option().
|
|
This also affects the mp.set_property_native() Lua function.
|
|
- generally, setting choice options/properties with "yes"/"no" options
|
|
can now be set as MPV_FORMAT_FLAG
|
|
- reading a choice property as MPV_FORMAT_NODE will now return a
|
|
MPV_FORMAT_FLAG value if the choice is "yes" (true) or "no" (false)
|
|
This implicitly affects Lua and JSON IPC interfaces as well.
|
|
- big changes to vo-cmdline on vo_opengl and vo_opengl_hq (but not
|
|
vo_opengl_cb): options are now normally not reset, but applied on top
|
|
of the current options. The special undocumented value "-" still
|
|
works, but now resets all options to before any vo-cmdline command
|
|
has been called.
|
|
--- mpv 0.12.0 ---
|
|
1.20 - deprecate "GL_MP_D3D_interfaces"/"glMPGetD3DInterface", and introduce
|
|
"GL_MP_MPGetNativeDisplay"/"glMPGetNativeDisplay" (this is a
|
|
backwards-compatible rename)
|
|
--- mpv 0.11.0 ---
|
|
--- mpv 0.10.0 ---
|
|
1.19 - add "GL_MP_D3D_interfaces" pseudo extension to make it possible to
|
|
use DXVA2 in OpenGL fullscreen mode in some situations
|
|
- mpv_request_log_messages() now accepts "terminal-default" as parameter
|
|
1.18 - add MPV_END_FILE_REASON_REDIRECT, and change behavior of
|
|
MPV_EVENT_END_FILE accordingly
|
|
- a bunch of interface-changes.rst changes
|
|
1.17 - mpv_initialize() now blocks SIGPIPE (details see client.h)
|
|
--- mpv 0.9.0 ---
|
|
1.16 - add mpv_opengl_cb_report_flip()
|
|
- introduce mpv_opengl_cb_draw() and deprecate mpv_opengl_cb_render()
|
|
- add MPV_FORMAT_BYTE_ARRAY
|
|
1.15 - mpv_initialize() will now load config files. This requires setting
|
|
the "config" and "config-dir" options. In particular, it will load
|
|
mpv.conf.
|
|
- minor backwards-compatible change to the "seek" and "screenshot"
|
|
commands (new flag syntax, old additional args deprecated)
|
|
--- mpv 0.8.0 ---
|
|
1.14 - add mpv_wait_async_requests()
|
|
- the --msg-level option changes its native type from a flat string to
|
|
a key-value list (setting/reading the option as string still works)
|
|
1.13 - add MPV_EVENT_QUEUE_OVERFLOW
|
|
1.12 - add class Handle to qthelper.hpp
|
|
- improve opengl_cb.h API uninitialization behavior, and fix the qml
|
|
example
|
|
- add mpv_create_client() function
|
|
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 ---
|
|
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 ---
|
|
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 ---
|
|
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 ---
|
|
1.0 - the API is declared stable
|
|
