5 years ago Mobile processors are not very powerful. So executing ffmpeg commands on mobile devices can be considered as slow when compared to desktop machines.
If an execution is taking too much time then you need to test different things to see if a performance improvement is possible.
- An issue about the release can cause a performance decrease. You can try different versions, different packages to see if a package/version has performance issues.
- Sometimes disabling logs or statistics improve the performance on mobile devices. You can try disabling them.
- An invalid or not supported option can cause performance decrease. Most of the time a warning is printed on logs about that. You need to check your logs.
ffmpegis not a simple application and supports many Advanced Options. You need to test different options to get the best performance.- Extrernal libraries like
x264has their ownx264-params. You can try differentx264parameters to improve the performance.
