DVD playback is slow on AmigaONE-X1000. #44

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Playing a DVD on X1000 using DVD://1 or DVDNAV://1 is horribly slow, even when 
using cache the problem is not solved.

If the cache is full, and there is no DVD activity the video plays fine, but as 
soon as DVD starts reading the speed drops. Its not a cache under run its, its 
cache overrun.

All DVD reading is happening using DoIO not SendIO / BeginIO, this might be 
improved, maybe the cache is locked some how, during DVD reading.

What steps will reproduce the problem?

1. Mplayer dvd://1 -dvd-device sb600sata.device:1 -cache 8000

I Googled a bit and issue seams to be related to version of mplayer we have.

so we need to update mplayer core.

Fixed in r87, problem with device io on AmigaOS4, does not pre-fetch blocks, to 
prevent inefficiency, when filesystem or program asks for 1 bock instead of a 
track, pre-fetching blocks saves time as fewer disk io commands needs to send 
to the sb600sata.device.
