Thread: ffmpeg and dual core.

im converting alot of tv shows use on ipods.

wrote small bash script can run on eash season like.

code:

for file in *.avi   ffmpeg -y -i "$file" -threads 2 -s 320x180 -vcodec mpeg4  -ab 128k -acodec libfaac -ac 2 -ab 64k -f mp4 "ipod/$file.mp4"  done

i have set threads 2, still uses 1 core.

started thinking , alter script cue files run 2 @ time, dont know how, appriiated.

you can better results libx264 create h.264 video , automatically detect proper threads value. here's example using ipod320 preset:

code:

ffmpeg -i input -acodec libfaac -ac 2 -ab 128k -vcodec libx264 -vpre hq -vpre ipod320 -crf 26 -threads 0 -f ipod -metdata title="a history of ham" output.mp4

i must admit don't own ipod test command, have no reason doubt effectiveness of it.

recommend compiling x264 , ffmpeg if you're going convert more few videos. development active , compiling gives recent version can make sure you're not missing exciting new features:

howto: install , use latest ffmpeg , x264
