Jpeg decoder

SDL Development

Hello!

I fetch 25 jpgs per seconds from a webcamera. When i have theese in memory
i want to show them.
Right now I use SDL_image classes to load the jpg from memory.
This way however take to much cpu and to long time.

Anyone know a faster and better way?!?!

Use a MPEG stream from your camera…

you might also try an uncompressed or less compressed format…

the more deeply compressed an image is, the longer it takes to decompress it
most of the time.> ----- Original Message -----
