// Pangolin video output supports various formats using
|
|
// different 3rd party libraries. (Only one right now)
|
|
//
|
|
// VideoOutput URI's take the following form:
|
|
// scheme:[param1=value1,param2=value2,...]//device
|
|
//
|
|
// scheme = ffmpeg
|
|
//
|
|
// ffmpeg - encode to compressed file using ffmpeg
|
|
// fps : fps to embed in encoded file.
|
|
// bps : bits per second
|
|
// unique_filename : append unique suffix if file already exists
|
|
//
|
|
// e.g. ffmpeg://output_file.avi
|
|
// e.g. ffmpeg:[fps=30,bps=1000000,unique_filename]//output_file.avi
