  • How to get the real, actual duration of an MP3 file (VBR or CBR) server-side

    25 septembre 2016, par SquareCat

    I used to calculate the duration of MP3 files server-side using ffmpeg - which seemed to work fine. Today i discovered that some of the calculations were wrong. Somehow, for some reason, ffmpeg will miscalculate the duration and it seems to happen with variable bit rate mp3 files only.

    When testing this locally, i noticed that ffmpeg printed two extra lines in green.

    Command used :

    ffmpeg -i song_9747c077aef8.mp3

    ffmpeg says :

    [mp3 @ 0x102052600] max_analyze_duration 5000000 reached at 5015510
    
[mp3 @ 0x102052600] Estimating duration from bitrate, this may be inaccurate

    After a nice, warm google session, i discovered some posts on this, but no solution was found.

    I then tried to increase the maximum duration :

    ffmpeg -analyzeduration 999999999 -i song_9747c077aef8.mp3

    After this, ffmpeg returned only the second line :

    [mp3 @ 0x102052600] Estimating duration from bitrate, this may be inaccurate

    But in either case, the calculated duration was just plain wrong. Comparing it to VLC i noticed that there the duration is correct.

    After more research i stumbled over mp3info - which i installed and used.

    mp3info -p "%S" song_9747c077aef8.mp3

    mp3info then returned the CORRECT duration, but only as an integer, which i cannot use as i need a more accurate number here. The reason for this was explained in a comment below, by user blahdiblah - mp3info is simply pulling ID3 info from the file and not actually performing any calculations.

    I also tried using mplayer to retrieve the duration, but just as ffmpeg, mplayer is returning the wrong value.

  • FFMpeg Continuous Real-time Image to Video Encoding

    4 juillet 2014, par Ben

    I am trying to use FFMpeg to take a stream of image files and turn them into a video. Now, I have successfully done this, but only after I have already captured all the images that I want. What I would like to do is turn the images into a video as they are saved to disk (real-time video recorder). Currently, when I call FFMpeg while frames are still being grabbed, it only encodes the number of images that are present when it is called. If FFMpeg is called every time an image is grabbed, it floods the CPU with a ton of processes. Ideally, FFMpeg would continue to encode the images until there are no more images being captured (I.E., check if there are more image files since it was first called). Is there an argument for FFMpeg that I’m missing, or is this not possible ? Or is the only way to do this through messing around with the libraries ?

  • How to get real video duration in php with ffmpeg [closed]

    24 avril 2013, par user82098

    ffmpeg -i *filename* tries to get info from video headers, but *filename* can be corrupted and then headers data will be incorrect
    for example ffmpeg -i *filename* can return me smth like "Duration : 00:20:21.09"
    but after converting *filename* I get video w duration 00:05:13
