# FFmpegHapGlPlayer
This repo contains "[FFmpegHapGlPlayer](https://github.com/mattbeghin/FFmpegHapGlPlayer)" as VS2017 project, and includes all required binary libs and include files to build for x64 Release. If you want to build for Win32 and/or Debug, you have to configure and compile the needed libs (ffmpeg, SDL2, snappy) yourself.

Original README:
Very simple cross-platform code to playback a HAP video file using FFMPEG for demuxing and HapDecode/OpenGL for decoding.
It handles Hap, Hap Alpha, HapQ but not HapQ+Alpha since it's not recognized by ffmpeg today (july 2018).
The idea in this project is to demonstrate how to:
- demux a HAP video file using FFmpeg / libavformat
- decompress the snappy compression using HapDecode
- send the compressed DXT buffer to an OpenGL texture (or two if HapQ+Alpha but this format is not yet supported in FFMPEG...)
- render the texture using OpenGL (with a specific shader in case of HapQ)
It uses SDL2 to create an OpenGL window.
I've been searching for how to do this process and couldn't find a simple sample, so here it is.
As it's only to demonstrate the process, it ignores any audio track, and I took some shortcuts (freeing resources properly, SDL_Delay call etc.), so the code is small enough to focus on demux->HapDecode->texture(s)->shader->display.
