Cropping and transforming; combining both on commandline

Postby Timothy Grove » 19 Jul 2017 13:05

What is the correct way to use multiple video filters in the command line? I'm trying to crop and tranform in one go with the following commands:

vlc.exe some_movie_file --video-filter=croppadd --croppadd-croptop=20 --croppadd-cropright=20 --croppadd-cropbottom=20 --croppadd-cropleft=20
--video-filter=transform --transform-type=90

Cropping or transforming on their own works fine, but together as above, only the transforming is performed.

Currently testing with 2.2.6 on Windows. Thanks for any suggestions.

Some documentation somewhere said that more than one filter could be used by separating them with a comma, so I tried "--video-filter=croppadd,transform", which didn't work. An inspired guess led me to try using a colon instead of a comma, which worked! Making the necessary changes to my previous attempt gave me the following successful command line:

vlc.exe some_movie_file --croppadd-croptop=20 --croppadd-cropright=20 --croppadd-cropbottom=20 --croppadd-cropleft=20
--transform-type=90 --video-filter=croppadd:transform
