  • How to speed up ffmpeg video conversions [closed]

    24 janvier 2013, par PIKP

    I need to extract the audio as a MP3 file from a given video file. I have selected "ffmpeg" for audio extraction process. with the use of following arguments I have managed to extract the audio as a MP3. this work very well. but it takes about "2 minutes" to extract the audio from "21 minutes" long video file.

    ffmpeg -i source_video.avi -vn -ar 44100 -ac 2 -ab 128k -f mp3 sound.mp3

    for my purpose "2 minutes" for "21 minutes" is a long time. I need to speed up this as much as possible.

    could someone please tell me what are the factors that control the conversion speed ?

    currently I'm using a SATA hard disk with 7500rmp, will it speed up the conversion process if I upgrade my hard disk to SSD ?

    Thank you !

    Speed 2 feature adjustment.

    With sf->auto_mv_step_size on it is questionable
    whether sf->reduce_first_step_size is worthwhile.
    At speed 2 it was not having a big impact.

    Even at speed 2 sf->optimize_coefficients = 0 is not
    having a big speed imapct so for now I have moved it
    down into a higher speed setting.
