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).
After playing a bit with libjpeg and libjpeg-mmx, I got at best 13fps for encoding only (no write operation to disk). This leads me to 2 questions. 1) I have absolutely no idea if 50fps is very high or quite reasonable, and I can't find many benchmarks of libjpeg and other open-source jpeg libraries, so I'd like to know if one of you have more experience with MJPEG encoding performance and could share his/her experience with me. 2) I get very similar results using libjpeg-mmx and libjpeg on a P3-800 (both optimized for i686). Is this normal ? I would have expected libjpeg-mmx to be faster. Thanks for your help.
