How to speed up the video compression?

[ananth10]

Hi ,

I am using following command to compress video in android . but it takes more time. e.g for 1 min video it takes 50sec to compress.

-y -i "+mInputPath+" -vf -s 640x480 -threads 5 -preset ultrafast -strict -2 "+mOutputPath.getAbsolutePath();

Does anyone know how to increase speed?

I'd love to know this too. I think though for the line you pasted doing -threads 5 might make it slower since -threads is default auto. If it can actually use more threads, you would be limiting it.

If you can use libx264, use this command. -y -i "+mInputPath+" -c:v libx264 -preset ultrafast -tune fastdecode -vf -s 640x480 -threads 5 -strict -2 "+mOutputPath.getAbsolutePath();

-preset ultrafast maybe will not work without libx264. libx264 has the preset ultrafast. To using libx264, you must build libx264 and rebuild ffmpeg.(as --enable-libx264)

In my case, when using x264 ultrafast, performance was about 3-4 times faster in reverse filter.

@novawoo-kr I'm facing with same problem. Can you help me to rebuild ffmpeg? Do you have any tutorials ?
