.SH SPECIAL CONSIDERATIONS
.TP
.B Frame Dumping 
When dumping a frame, either the frame number (sample number) can be specified or the frame time
in the format hh:mm:ss:xFz where hh, mm, ss are hours, minutes, seconds, x the number
of the frame in the seconds and z the frame rate used to express the time
.TP

.B Input Files
The current version of MP42AVI is only designed to handle pure BIFS presentation. If the input BIFS scene uses audio or visual media, these are ignored during the dump. It may even crash MP42AVI.
.TP
.B GPAC Config File
MP42AVI needs the GPAC configuration file in order to locate the different plugins used for rasterization. You must therefore have launched successfully MP4Client before trying to use MP42AVI
