the hap-codec (https://github.com/Vidvox/hap) uses the graphic card
instead of the CPU for decoding, which would make it much faster at
higher resoluions. appearently it's "a thing" in the world of vj-software.
a quick check on my system (ubuntu 16.04) reveals:
- mplayer doesn't know what it is
- ffmpeg, encodes and plays it (DEVIL), but doesn't know when to stop
(keeps on playing the last frame)
- pix_film claims it's just 1 frame at -1 fps
i followed the dependency chain and i think (not 100% sure) pix_film
uses libquicktime, which in turn uses ffmpeg to play it.
i was wondering, how difficult it would be to add stable support for the
hap-codec in Gem. maybe even bypassing libquicktime/ffmpeg alltogether?
has anyone looked into it yet?
many thanks for any input,
