My answer :
I'm sure many would be interested to know which of the tips given worked. Could you please post what hardware you're using, what grab tool, and the parameters used?
I am using a BT878 card, with a Sony Camera X97C ..to get image in RGB 32 bits.
With what capture tool? What parameters?
Do you have a method to display the grabbed frame on screen with 25 fps ??
Thanks Again
Depends on the format used to save the frames! mplayer ( www.mplayerhq.hu ) can play a wide variety of formats.
I am using XLib to display my grabbed frames but it can display 6 ou 7 fps !!
Do you know how to improve my display ?
Thanks
Then you have written your own tool, and you want to display the frames as you grab them, right? Difficult with Xlib. State-of-the-art players use direct access to the screen for faster display. If you want to save, then replay later: nvrec and mplayer. If you want to see 'relatime' but not save: tvtime. If you want both... 25fps grab AND 25fps display... not sure it can be done.
