This player stands on the giant shoulders of FFmpeg. Audio rendering is accomplished via portaudio v19. Video rendering is via OpenGL, using fragment programs when possible. User interface is implemented with Qt 4/5/6. ASS/SSA subtitle rendering is implemented with libass. This player provides several performance options to enable adequate video playback on slow hardware: * skip loop filter * skip non-reference frames * skip color converter * reduce playback speed to accommodate slow video decoding This player supports playback of HDR video on non-HDR displays: * colorspace transform to BT.709 colorspace via an auto-generated 3D LUT * tone mapping from HDR to SDR (BT. 709) This player supports playback of MPEG-TS files containing multiple programs, timeline anomalies, and codec changes. Linux binaries are provided as AppImage, built on Ubuntu 14.04.

Pineapple MIDI Player is a simple SoundFont MIDI player, designed to play simple MIDI file together with SoundFont file, especially MIDI files extracted by tools like VGMTrans. This tool will attempt to load the SoundFont with the same file name as the MIDI file by default, and support change SoundFont on-the-fly when dropping a SF2 file onto the main window.

Volocian believes first and foremost that financial status shouldn’t be a barrier to entry in multimedia content creation.

Modus is an open source, cross-platform C++ library which allows you to handle music from code. This means that you can: * Manage interactive and adaptive music * Use some kind of algorithm to improvise * Represent visually (simulate) musical performances * Select in real time the instruments that are going to play a previously written song * Let the user take part on the performance through any type of interface, by playing an instrument, changing the tempo, choosing the instruments, designing the structure of the song, etc. * Define song structures with metric modulations, accelerandos and ritardandos * Write your own scores, which can then be assigned to instruments to be played * Play along with a pre-recorded song or represent the performance * Everything else that comes into your head

A small cross platform CLI tool which will help in producing different types video converting codes quickly for new ffmpeg CLI users. The tool will make it easy to generate ffmpeg commands for them. If you don't use or know about FFMPEG then this tool might not be for you. This tool is created for those who find it difficult to understand or find the appropriate commands for converting a video as they want using the FFMPEG CLI tool. Also those who are new to Command Lines they can also use this tool to generate ffmpeg commands very easily. Many new ffmpeg users find it difficult to find the appropriate ffmpeg commands to convert their videos to with their desired configs. So, as a result they end up googling a lot and wasting their time. So this tool is for them.
