That would be ideal. do you happen to know if the building blocks - the key high-cpu-load parts - of HEVC (aka H.265) _happen_ to be the same or near-identical to MPEG or H.264 and so on? also critical will be a YUV->RGB converter plus scaler... and oh look! https://opencores.org/project,video_stream_scaler if anyone remembers the National Semi Geode LX800 (bought by AMD), that, staggeringly, could actually do 720p video displayed on 1600x1200 (with a bit of a tear at times), and could easily do 1280x720 (without tearing) @ 30fps.... *ENTIRELY IN SOFTWARE*... because it had a YUV->RGB converter hard macro that took care of the most expensive bit. ... and that was a 500mhz 486 with DDR2 RAM! absolutely incredible. so, anyway, yes: each little piece of the puzzle will be needed, saving big chunks of CPU cycles. l. _______________________________________________ arm-netbook mailing list [email protected] http://lists.phcomp.co.uk/mailman/listinfo/arm-netbook Send large attachments to [email protected]
