Sure the 3rd option is much simpler, and since MLT doesn't currently
support > 8bit buffers it won't make much difference in the result.
A simple patch is in my github's fork:

It supports both missin

Hi,
I think you have a few options:
1) Create a new image type in MLT: mlt_image_yuva444p16
I do not recommend this because it wou

The AV_PIX_FMT_YUVA444P10LE uses 10bits for each chanel. So I cannot

Hi all,
In order to optimize performance, in the qtblend transition (in the qt
module), I try to detect if the top frame in the transition has

However currently, to check if a frame has transpa
