there is at least patch for that.) Maybe we should make libv4l plugable in this respect? So that different underlying libraries could be easily swapped and tested and used? Or just use different compilation switches and let distribution maintainers decide which one they want to use? Mitar -- To unsubscribe

, it would be useful to increase those hardcoded limits in ib/libv4lconvert/tinyjpeg-internal.h to for example: #define JPEG_MAX_WIDTH 4096 #define JPEG_MAX_HEIGHT2048 Now we have affordable cameras which have bigger frame sizes than those currently hardcoded. ;-) Mitar -- To unsubscribe

Hi! Could be, but I'd like to know if increasing the control streaming timeout is required as well. I had some time now and have tested it and it is enough just to increase UVC_CTRL_STREAMING_TIMEOUT to 5000, I left UVC_CTRL_CONTROL_TIMEOUT at 300. And everything seems to work. Mitar
