- Apply double speed for all voice tracks, not only for the current.
- Use dedicated atomic in Mixer for the voice speed (fix race).
- Store the playback speed in user settings, not in global settings.
- Use float64 for setting (just consistency, no float-s right now).
This adds double playback speed for both voice messages and round video
messages.
The 2x playback speed setting is global and is saved in local storage.
Fixes#4907
base::lambda -> Fn (type alias for std::function).
base::lambda_once -> FnMut (type alias for base::unique_function).
base::lambda_guarded -> crl::guard.
base::lambda_call_type_t -> crl::deduced_call_type.
Also fix voice message mark as read when autoplaying after previous.
Also show play icon and don't show playlist for audio files that do
not have shared music files attributes but have audio file mime type.
Media::Player::Widget displays the current voice / video message
if it is played and the current song otherwise.
It is created when a voice / video message starts and is destroyed
when all the voice / video messages in the playlist are finished.
Use AudioMsgId instead of videoPlayId.
Any audio track now can be a child loader track of some video clip.
Use Type::Voice instead of Type::Video for round video messages.
Video messages play / pause / resume the same way as voice messages.
Also add some more decoders in ffmpeg configuration (wav).
Also stop audio device restart on PKEY_AudioEndpoint changes.
Also deduce channel layout from channel count in ffmpeg loaders.
Currently the build without implicitly included precompiled header
is not supported anyway (because Qt MOC source files do not include
stdafx.h, they include plain headers).
So when we decide to support building without implicitly included
precompiled headers we'll have to fix all the headers anyway.
Media::Player::Instance started to notify about all sound
playback updates, even for video files (which do not have
DocumentData filled in), while Media::Player widgets were
relying on the existance of DocumentData in each update.
