usage_description="
|
|
Converts one or more AVI files given or found recursively under given paths or current directory to mp4 format using ffmpeg
|
|
|
|
Useful to be able to stream videos to devices like smart TVs that may otherwise not understand the codecs used in the original format
|
|
|
|
Names the generated files the same except with the '.avi' extension replaced with '.mp4'
|
|
|
|
Skips files which already have a corresponding adjacent '.mp4' file present to be able to resume partial directory conversions, and also removes partially complete files for consistency using bash trapping
