Evolution #4419 (Nouveau) : Mettre à jour la lib jquery.flot
26 décembre 2019, par Franck DHello :)
https://zone.spip.net/trac/spip-zone/browser/spip-zone/_core_/plugins/statistiques/javascriptPendant des années, la lib ne bougeait plus, la 0.8.3 date du 21/04/2014

FFmpeg error : Unable to find a suitable output format for ''
11 juillet 2020, par Benjamin BasmaciI'm new to ffmpeg as well as Android programming. I'm trying to load a video from a URL and crop it with ffmpeg. I want to save that video to a file. This is the command I found online :


"-i " + videoUrl + "-filter:v crop=240:120:100:100 -c:a copy test.mp4"



I have tried it and got the error
Unable to find a suitable output format for ''


So I tried to narrow the possible cause down and tried these commands as well :


"-i " + videoUrl + " -c:v copy -c:a copy test.mp4"
"-i " + videoUrl + " -c:v copy test.mp4"
"-i " + videoUrl + " -c:a copy test.mp4"
"-i " + videoUrl + " test.mp4"



So with that last one I basically boiled it down to the bare minimum of what a comment needs, as far as I know. But still, same result.


All of them give me the same error. Here is the full output I got via
FFmpeg.getLatestOutput()

Why does ffmpeg assume that I have given it no output format and what I need to do to make this work ?


I'm using
implementation 'com.arthenica:mobile-ffmpeg-full:4.2'
.
