  • How to convert .flv file to .3gp using ffmpeg ? [migrated]

    19 octobre 2011, par Chetana

    I have converted any video format to 3gp file format using ffmpeg on one server.
    But on another server it not works.

    Following is my script :

    exec("ffmpeg -i test.flv -sameq -acodec libmp3lame -ar 22050 -ab 96000
    
    -deinterlace -nr 500 -s 320x240 -aspect 4:3 -r 20 -g 500 -me_range 20
    
    -b 270k -deinterlace -f flv -y test.3gp ");

    Can anyone tell me what is wrong in script ?

    Following is my ffmpeg setting :

  • FFMPEG : i need audio channels 7 & 8 to be the main audio track for a video

    10 avril 2013, par lo_fye

    I have a video with 8 channels of audio.

    I need tracks 7 (Left Stereo) and 8 (Right Stereo) to be the audio for the video (which I'm converting to flv).

    I've tried playing with -filter_complex and the join, amix, and amerge filters, as well as the -map parameter, but I can't seem to find the right combination of values :-/

    Output :

    /usr/local/bin/ffmpeg-1.0/bin/ffmpeg -i &#39;/folder/video_name.mov&#39; -f &#39;flv&#39; \
