  • -shortest is not working while looping audio with amovie in FFMPEG

    18 juin 2019, par Nikunj Paradva

    Here input is two video total 40 second, i am concate that and speed up 4x,then video duration is 10 second,

    audio input duration is dynamic it ll be shorter than video or bigger than video duration that’s why i am using amovie command for replace audio with looping to infinite, and add -shortest command at last.

    but it won’t be worked. it goes to infinite process.

    Here is my command

    [-y,
    
 -i, /storage/emulated/0/Received/VID-20190407-WA0001.mp4,

  • How to fix : Frame rate differs from source after encoding certain mp4 videos to wmv

    25 juin 2019, par hpenhp

    I’m having trouble with a usually working ffmpeg script for encoding mp4 and more to wmv. The goal is to keep it like the original, except for the resolution (smaller) and the format (wmv).

    When it usually works for a lot of videos, on some of them it doesn’t... and i would like to understand and avoid that.

    I tried several things, forcing the framerate for the output, using -vsync 2 option, -vsync 0 also.. noone of that fixed the issue.

    An other thing, worth adding, is that the fps value from media info is good (24 fps) on the output like the input, but through the M$ windows explorer, it says 30 frames per sec, and when you play the video you see that the text that was matching the input doesn’t match the output any more (because of the fps mismatching).

    Below the script i use :

    ffmpeg -threads auto -i input.mp4 -s 480*320 -b:v 1000k -vcodec msmpeg4 -acodec wmav2 -f asf output.wmv

    Here is the ffmpeg log :

    EDIT :
    My workaround was to encode to MPEG, doing this, i’m able to read my file and the frame rate is same as source. If someone knows why it couldn’t keep the original framerate in wmv, i’m still interested to know.

  • Converting avi to mp4 (use ffmpeg library) is very slow [closed]

    7 décembre 2012, par yAnTar

    I have task - convert any video from user to mp4 format.
    I use command

    ffmpeg -i $file -vcodec libx264 -vpre ultrafast -bt 500k -acodec libfaac -ab 56k -ac 2 -s 480x320 $outputFileMp4

    I try to change options bitrate, dimensions, but spped of converting is slow - 3 mbytes convert arround 90 seconds.

    If i convert avi to flv - no problem.
