qtmultimedia-plugins-mdk

qt multimedia plugins implemented on top of mdk-sdk

Multimedia plugins are looked up in alphabetical order, so mdk plugin may be not selected. Since Qt5.13 environment var QT_MULTIMEDIA_PREFERRED_PLUGINS=mdk can enable mdk as backend.

Features

• All formats. You can replace ffmpeg library in the sdk to support more formats
• GPU decoders (hardcoded because of qtmutimedia limitation, see QTBUG-74393
• Optimized OpenGL rendering
• HDR tone mapping

Build

• Download a sdk from https://sourceforge.net/projects/mdk-sdk/files/nightly or https://github.com/wang-bin/mdk-sdk/releases
• Extract sdk into this dir
• Build and install. In QtCreator you can add a Make step with Make arguments: install. Then plugin and mdk runtime files will be automatically installed to Qt dir
• Try an Qt multimedia example

Note: mdk-sdk-apple.tar.xz contains xcframework which is not supported yet in this project, use mdk-sdk-macOS.tar.xz or mdk-sdk-iOS.tar.xz instead

Issues

• Qt for android adds abi suffix to shared libraries to support muliti abi, libmdk has no such suffix
