This adds screencast support on Linux. This is based on
ffmpeg for the encoding & muxing (default format is MP4 with AAC audio
and H264 video).
The microphone sound is grabbed using QAudioInput. The encoder should
be able to handle virtually any input format (it has been tested with
a stereo input at different sampling rates with one format (16-bit
signed) but it should work fine with any number of channels, sample
format etc.).
The only problems I have run into so far are that desktop recording is
very slow (compared to OS X) and that the last few video frames are
usually not included in the video. This may be due to GOPs not being
complete, but that's just a wild guess.
Caused problems e.g with podcast mode, where if the control and display
views were swapped in the preferences, the wrong screen would be recorded
when switching to desktop mode during recording of the podcast.
This happened even if only one screen was plugged in, so a black screen
was recorded in that case (at least on OS X 10.10)
- Qt plugins and libraries (and associated files) bundled only if necessary
- Dependencies corrected (for Ubuntu 14.04 and 16.04, at least),
mostly manually for now
- run.sh sets Qt plugin path environment variable (=> qt.conf
no longer needed; removed)
- Separated building and packaging
- OpenBoard is now installed in /opt/openboard instead of
/usr/local/OpenBoard-$VERSION/
- Placed a shortcut to run.sh in /usr/bin (so it can be executed with
the `openboard` command)
- Corrected .deb control files to avoid warnings e.g when installing via
software center on Ubuntu
- Added xdg bindings so that .ubz files are recognized and opened
automatically with OpenBoard
- Moved the release scripts into their own folder to clean up the
repository root a bit
(Merge branch 'new-release-script-linux' into dev)
- Fixed permissions of qt libs and plugins
- Added some missing plugins (and maybe a couple too many)
- Dependency list is built automatically, while excluding qt libs
