Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

FFmpeg transcoding stretches Vertically recorded videos
28 juin 2017, par oteammHi I am having an issue with the Transcoder (FFmpeg) .
Problem Details :
Vertically recorded videos are appearing stretched (widened) upon transcode.For videos which are recorded vertically (height is more than width), the transcoded video generated does shrink vertically. If we change the aspect ratio for such files it will ruin the other video transcodes for which the transcode is generating correctly.
Expected Behaviour :
should not shrink/stretch vertically recorded videosImpact :
we are seeing a distorted version of video, stretched horizontallyNotes :
Version of FFmpeg Software that you’re is used : - ffmpeg-2.8.6-win64
(default Settings used)Request :
Need to a way to correct this as if we change the aspect ratio for such files it will ruin the other video proxies for which the proxy is generating correctly.
Please suggest, if there is any way to AUTO select the aspect ratio of original file and generate transcode accordingly. Thanks ! -
