SMJPEG
SMJPEG is a open format for motion JPEG files.
Advantages of SMJPEG:
- Arbitrary video sizes (not limited to blocks of 16 pixels)
- Arbitrary frame-rate
- User-tuneable compression level
- Much easier to skip a frame
- Much easier to keep timesync
- Easy to seek within the video stream
- Free of patent problems
Disadvantages of SMJPEG:
- Not a standard format
- Poorer quality than MPEG at the same file size
- Slightly slower than MPEG at the same framerate
- Not designed for Internet streaming
The SMJPEG file format is documented in the file SMJPEG.txt.
