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 0.12.0 ---
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
