Raw stream is simple, for example YUYV need 16 bits to describe one pixel. No extra action is done on this stream. Even if the camera lie about it setting, we can still calculate it our self. For example if you use YUYV 640x480 with 30 fps: 640×480×16=4915200 bit or 4915200/8=614400 byte so

Compressed stream is not really predictable. Every camera can act differently, so my be it will brick more than fix. Do your camera need this quirk? Am Donnerstag, den 10.03.2011, 19:43 + schrieb modysama: modysama asmaa.elassal.student at pua.edu.eg writes: Fixing bandwidth quirk is
