That's because yuv2lav is not multi-threaded -- it reads from the YUV stream, compresses the image, and writes it to the output file, all in one thread. Fixing that is one of my near-future planned projects (sometime after finding a new place to live & getting a day job :-).

Maybe a disk-cache flush that hangs the thing for a

Hi everybody,
I've been asked today by my boss to see if I can find a way to get software
MJPEG encoding for PAL-size (768x576) RGB images at a double real-time rate
(50fps).

encoding only (no write operation to disk). T
