  • ffmpeg sequence starting at frame 1001

    11 février, par Kernowkid

    I have an image sequence starting at 1001 that I'd like to convert to a mp4 using ffmpeg. Here's what I'm putting in cmd shell :

    


    ffmpeg -i plates_sh01_%04d.jpeg start_number 1001 -s 1920x1080 -vcodec libx264 -crf 25 -b:v 4M -pix_fmt yuv420p plates_sh01_%04d.mp4


    


    This works for image sequences starting at frame numbers below 999. For any sequence starting at 1000 or above I get this error :

    


    


    Could find no file with path 'plates_sh01_%04d.jpeg' and index in the range 0-4
plates_sh01_%04d.jpeg_%04d.jpeg : No such file or directory

    


    


    I can't find any solutions to this apart from re-number the image sequence.

    


    Any help is greatly appreciated.

    


  • MP3 files created using FFmpeg are not starting playback in browser immediately. Is there any major difference between FFmpeg and AVCONV ?

    23 janvier 2019, par AR5

    I am working on a website that streams music. We recently changed server from Debian (with avconv) to a Centos7 (with FFmpeg) server.
    The mp3 files created on Debian server start playback on browser (I have tested Chrome and Firefox) start almost at the same time they start loading into the browser (I used Network tab on Developer Tools to monitor this)

    Now after the switch to Centos/FFmpeg server, the files being created on this new server are displaying a strange behavior. They only start playback after about 1MB is loaded into the browser.

    I have used identical settings for converting original file into MP3 in both AVCONV and FFmpeg but the files created using FFmpeg are showing this issue. Is there something that might be causing such an issue ? Are there differences in terms of audio conversion between AVCONV and FFmpeg ?

    I have already tried

    I first found that the files created on old server (Debian/Avconv) were VBR (variable bitrate) and the ones created on new server were CBR (constant bitrate), so I tried switching to VBR but the issue still persisted.

    I checked the mp3 files using MediaInfo app and there seems to be no difference between the files.

    I also checked if both files were being served as 206 Partial Content and they both are indeed.

    I am trying to create mp3 files using FFmpeg that work exactly like the ones created before using avconv

    I am trying to make the streaming site work on the new server but the mp3 files created using FFmpeg are not playing back correctly as compared to the ones created on the old server. I am trying to figure out what I might be doing wrong ? or if there is a difference between avconv and FFmpeg that is causing this issue.

    I am really stuck on this issue, any help will be really appreciated.


    Edit

    I don’t have access to old server anymore so I couldn’t retrieve the log output of avconv. The command that I was using was as follows :

    avconv -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"

    Here is the command and log output from new server :

    ffmpeg -y -i "/test/Track 01.mp3" -ac 2 -ar 44100 -acodec libmp3lame -b:a 128k "/test/Track 01 (converted).mp3"
