Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.

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()

How to compile ffmpeg to get only mp3 and mp4 support
19 février 2019, par Enis JasarovicI’m building Electron app and I use ffmpeg to convert m4a or webm files to mp3, and also to merge video only mp4 with m4a audio file to mp4.
I am able to achieve this using [media-autobuild-suite] (https://github.com/jb-alvarado/media-autobuild_suite), using light build option, but the size of static files is arround 20mb and I’would like to shrink it a little bit more. I’ve compiled ffmpeg and ffprobe with this configuration.
