[GEM-dev] gem-mpv : high resolution video decoding in Gem

[Jack]

Hi Antoine,

I just tested this new object and thanks for it.

Here my comments :
- play and pause messages return mpv: no method for ...
- i was expecting less usage of CPU than the couple
gemframebuffer/pix_film. On my computer the CPU usage is the same.
- the sound of the video is audible, it will be nice to have x signal
outlets (with x channels of sounds) from the mpv object.

Hope, these comments can help.
