  • Why does ffmpeg report different durations ?

    18 mai 2012, par kenitech

    Source videos : http://www.artworknotavailable.com/tmp/ffmpegtest

    Quicktime Pro 7.7.1 Inspector (Win 7) reports the following for the file 2398.mov

    4.19MB
    H.264
    Movie FPS : 23.98
    Data Rate : 2.35 mbits/Sec
    Duration 14:97

    ffmpeg reports the following (see full ffmpeg version info at bottom of post)

    ffmpeg -i 2398.mov

    Seems stream 1 codec frame rate differs from container frame rate : 47952.00 (47952/1) -> >23.98 (2997/125)

    One second longer than what Quicktime reports.

    As an experiment I exported this file from Quicktime Pro using the following settings :

    Frame Rate : Current
    Key Frames : Every 24 frames
    Frame Reordering On
    Quality : High
    Encoding Best
    Data Rate : Automatic

    Movie FPS : 23.98
    Data Rate : 3.15 mbits/Sec

    ffmpeg now reports :

    ffmpeg -i qtime-export-2398.mov

    Seems stream 1 codec frame rate differs from container frame rate : 1200.00 (1200/1) -> 23.98 (24000/1001)

    ffmpeg's report on duration went from 15.97 to 14.96 (I can live with .1)

    Is this duration calculated from the bitrate ?

    I need to accurately report the duration of uploaded videos as well as convert them to FLV. Can somebody tell me what is going on here and how I might get around this ?

    ffmpeg info below. I've tried this on 2 completely different installs/versions of ffmpeg. Same result.

  • AMR to MP3 conversion with FFMPEG

    20 mai 2017, par 8vius

    I’m trying to convert AMR audio files to MP3 using FFMPEG. I’m running on Ubuntu 10.10 with VBox on Windows 7 host and i’ve installed ffmpeg by running sudo apt-get install ffmpeg I already have an AMR file that i’ve previously recorded so I ran the command : ffmpeg -i myfile.amr myfile.mp3 the conversion failed and the trace is as follows :

    So as per the indications of this thread ffmpeg : convert audio-only flv to swf I ran the command sudo apt-get install ffmpeg libavcodec-extra-52
    to install the extra libraries and i still have the same issue. Any other ideas ?

    UPDATE : also in the thread they link to this site to make it work http://stephenjungels.com/jungels.net/articles/ffmpeg-howto.html followed all the steps and it still won’t work

  • ffmpeg not giving correct duration of a mp4

    1er juin 2012, par oach

    I am working with ffmpeg to convert videos into flv files via php. The tests I have done do not work for mp4 conversions. I have a 13 second video (videos will be limited to 15 seconds), when it is uploaded and I check the "duration" of the video it comes out over 300 seconds. I have tried changing around how I process the video :

    // original
    
exec(&#39;ffmpeg -i <path>/<filename> 2>&amp;1&#39;, $output);
    

    
// current
    
exec(&#39;ffmpeg -i <path>/<filename> 2>&amp;1 | grep "Duration" | cut -d \&#39; \&#39; -f 4 | sed s/,//&#39;, $output);
    
</filename></path></filename></path>

    The original method did not work for mpg files but the second does, but neither gives me the "correct" duration of a mp4 video. Is there a "special" way to process mp4 files ?

    Thank you for your time and help.

    Update :

    Command line

    ffmpeg -i ./custom_scraping.mp4 2>&amp;1 | grep "Duration" | cut -d &#39; &#39; -f 4 | sed s/,//
    
00:05:15.84

    Complete output (formatted as best I could)

    Don't know if it helps but from the listing of the file in Linux :

    Let me know if anything else is needed.
