hi,all
I am trying to read video frames from a bt878 video capture card,and show video frames on screen.For real
time purpose,each frame must be drawn on screen every 40ms(25fps).
By now ,I use gtk_timeout_add/remove to do this.This method works well for 1 or 2 video channel,but when it
comes to 3 or more cahnnels,it seems that some viedo frames are losed.
How can I solve this problem?
Is the timeout event suitable for this application?
Or I should directly operate on my Pc's video card to save time?
And if there is some widget ,like direct X ,OpenGL ,
can be used ?
Thanks!
