xconv ffmpeg wrapper based on AdvancedAV
|
|
|
|
|
-----------------------------------------------------------
|
|
|
|
|
AdvancedAV helps with constructing FFmpeg commandline arguments.
|
|
|
|
|
|
|
|
|
|
It can automatically parse input files with the help of FFmpeg's ffprobe tool (WiP)
|
|
|
|
|
and allows programatically mapping streams to output files and setting metadata on them.
