Hi,
after looking through the code of bttv-0.9.10 and saa7134-0.2.7, I have
still some questions about streaming and reading the video resource.
If I've understood it correctly, this is how it's done.
Framebuffer ---------------------> System Memory (cacheable)
Video-Card DMA Transfer many buffers
(steered by interrupt)
Do the driver use double buffering for the framebuffer to separate the
frames properly ?
Is streaming done all the time, or does it stop after filling up all the
enqueued buffers ?
TIA,
Franz
