I modify uvc source code,generate a static image as uvc video streaming,and uvc work normal with as below resolutions.
// VGA Resolutions
{40, 30 }, /* QQQQVGA */
{80, 60 }, /* QQQVGA */
{160, 120 }, /* QQVGA */
{320, 240 }, /* QVGA */
{640, 480 }, /* VGA */
{60, 40 }, /* HQQQVGA */
{120, 80 }, /* HQQVGA */
{240, 160 }, /* HQVGA */
But when I use some special resolutions,like(120x90,256x192),uvc can’t work.And resolutions also ca’t work as below
// C/SIF Resolutions
{88, 72 }, /* QQCIF */
{176, 144 }, /* QCIF */
{352, 288 }, /* CIF */
{88, 60 }, /* QQSIF */
{176, 120 }, /* QSIF */
{352, 240 }, /* SIF */
// FFT Resolutions
{64, 32 }, /* 64x32 */
{64, 64 }, /* 64x64 */
{128, 64 }, /* 128x64 */
{128, 128 }, /* 128x64 */
// Other
{128, 160 }, /* LCD */
{128, 160 }, /* QQVGA2 */
{720, 480 }, /* WVGA */
{752, 480 }, /* WVGA2 */
{800, 600 }, /* SVGA */
{1024, 768 }, /* XGA */
{1280, 1024}, /* SXGA */
{1600, 1200}, /* UXGA */
Q:how uvc solution can support some special resolutions,like(120x90,256x192)?
and uvc resolution has ˈa standard?
