Re: [Cin] add Vulkan hwaccel

Thank you, just these days I'm testing with the “configure” flags; your patches happen right. In CinHV, Adam had put an option in the rendering window to write an ffmpeg command directly, without going through presets. An option that opens you a terminal (or a simple input window, as Adam did), makes you use external ffmpeg, and then the result falls back into the rendering window configuration would not be bad. This would get around the problem with the filter graph and using multiple streams that prevent some plugins from working. Do you think this is possible by copying Adam's commit?
