hi there,

when capturing dv with the linux version of gem's pix_video, this object emits frames about every 1/10th of a second only, no matter what framerate gem is running at. when using an usb camera, the behaviour of pix_video is as expected: it delivers one frame with every render cycle.

this is a bit less-than-ideal from my point of view, since fast movements won't be continously anymore. is there any way of changing this behaviour? also, while we are at it: the resulting images are really blocky sometimes, especially when capturing motion. it looks like some parts of the image consist of another frame than the rest of the image ... this issue does not exist when capturing dv with dvgrab or kino.

while working on this, i found myself craving for the windows version of pix_video: not only do these ugly blocks not appear, it is also possible to change the resolution of the captured video with messages (dv res xxx, iirc). this becomes important when doing other stuff besides capturing video: pix_video and the according pix_texture take up about 50% on my computer :-( thre is indeed a quality-message, but this one doesn't seem to affect the resolution of the captured frames, only their overall quality.

with kind regards, thoralf.
