Note 1
You can adjust the size of the primary input buffer with environment variables.
Note 2
Estimate is based on a 320x240 pixel image. Memory needed is very dependent on the image size being decoded. Also the primary input buffer size is user-configurable.)
Note 3
The size of the primary input buffer is variable.
Note 4
Depends on the .swf file.
