Media Playback Engine for Cinder
Update 11/12/2021
- Added a macOS backend that matches the API defined for the windows version, backed by cinder's native
qtime::MovieGl/qtime::MovieSurfaceimplementations.
This is effectively a wrapper around IMFMediaEngine (meaning it's currently windows 8+ only). IMFMediaEngine supports both a hardware accelerated and CPU implementation and AX-MediaPlayer provides a backend for each. Please refer to the SamplePlayback sample for usage as the method varies slightly due to the synchronisation / locking requirements of the hardware path.
I've taken reasonable care as it pertains to leaks but that is my first COM heavy library
so my first priority was to get it running and make sure it's leak-free later. Please report any
that you find, i've tried to use ComPtr et al judiciously so hopefully there's not too many.
I couldn't find any substantial information about thread safety when calling into the IMFMediaEngine,
but the audio related functions did not like being called from the main thread, so there's a provided
way to perform a lambda on the MTA thread which seems to make it happy. RunSynchronousInMTAThread ( ... ).
There's no documentation, please just have a look at the provided sample to see the basic usage. It's all fairly straight forward video-related stuff. You should be able to just check this out into your cinder install's block's folder and off you go. The sample is built against cinder 0.9.3 to utilise the built-in imgui debug UI, but should also work with 0.9.2 without the UI
This was just a one night project for fun so it comes with absolutely no warranty. Hopefully it still comes in handy for someone :)
