Create a file like this: https://pastebin.com/hFSeXsZt The first line is so ffmpeg can probe the format, then just have a "file" line followed by any number of "option" lines. Note that options are only allowed if safe-mode is disengaged, so the app in question would have to pass "-safe 0" to the execution in some manner. But this is something you would have to ask the app to do, as this protection exists for a reason. - Hendrik _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
