Regression was introduced in 2fa2fa41c5.
In file download failed handler we suggest to try to load the file
once again to the same location. After some changes we started to
forget filename before failed handler. That resulted in large files
loading to memory instead of hard drive.
Add a precondition in FileLoader to prevent such bugs in the future.
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.
Read media information (image / song / video) in SendFileBox in the
same way it is read in FileLoadTask::process() and reuse it in
FileLoadTask if it was loaded already for the box.
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.
Now base::lambda can be copied and can wrap any immutable lambda.
For mutable lambdas there is base::lambda_once (which you're
supposed to call only once to pass data through lambda captures,
for example by using std::unique_ptr). Generally base::lambda is
passed by value and base::lambda_once is passed by rvalue reference.
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.
