I wanted to modify my dvgrab code, but dvgrab uses libraw 0.6, no direct dma available there :-( [ yet? :-) ] Arne -----Original Message----- From: Sebastien Rougeaux [SMTP:Seb...@sy...] Sent: Wednesday, April 26, 2000 1:08 AM To: ar...@sc... Cc: and...@mu...; lin...@li... Subject: Re: My wishlist entry If I may suggest, you should try the new direct dma to user space feature I have announced the other day for the ohci driver. You can set the buffer size to the size of your dv encoded frame at run-time (it even does multi-buffering), and you save quite a bit of CPU time (the ohci hardware does frame sync and packet header/trailer stripping for you)... Definitely a must use for video acquisition, and I would welcome any feedback on it ;-) -- Sebastien Rougeaux RSISE, The Australian National University |
