webm to mp4 conversion using ffmpeg
2 décembre 2015, par Pavan KWhen I try to convert a webm file to mp4 the output is very very choppy and it appears as if many frames have been dropped by ffmpeg
I used the following commands to convert
ffmpeg -i movie.webm movie.mp4
ffmpeg -i movie.webm -vcodec libx264 movie.mp4
ffmpeg -i movie.webm -vcodec libx264 -qscale 0 movie.mp4All of them have the same problem. When I use ffprobe it seems to show the frames more or less properly.
