Unrecognized option from ffmpeg converting to html 5 video on upload
19 avril 2015, par peterbw321I am gradually getting the hang of video conversion with ffmpeg but am stuck. I am on shared hosting. I can convert with simple code like -
ffmpeg -i out.avi -acodec copy -vcodec copy output.mp4
I need to convert to html5 video formats but whenever i use code like this, I always get the same type of error ’Unrecognized option c:v’ or ’Unrecognized option b’. Is my version of ffmpeg too old ? Please help.
exec("/usr/bin/ffmpeg -i input -c:v libx264 -preset slow -crf 18 -vf yadif -strict -2 output.mp4");
