  • ffmpeg : convert FLAC to mp3 and add album art in one step

    19 juillet 2014, par Christian Riedl

    I convert FLAC to MP3 using

    ffmpeg -i x.flac -f mp3 -vn -b:a 64K x.mp3

    and I add album art using

    ffmpeg -i x.mp3 -i x.jpg -map 0:0 -map 1:0 -c copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (Front)" xx.mp3

    Is it possible to do it in one step ? Because I want to do it during "live" transcoding.

  • Static image and a folder of mp3's ?

    28 juin 2013, par Shirohige

    I want to create a bunch of videos consisting of an single image which is shown throughout the whole video but each video has a different audio file. I can do it manually with various tools but the problem is that I have a lot of audio files and I can't optimize the frame rate (more on that later) and it takes a lot of time to do it that way but ffmpeg offers everything I need but the problem is that I don't know how to batch process everything.

    The basic code :
    ffmpeg -i song-name.mp3 -loop 1 -i cover.jpg -r frame-rate -t song-length -acodec copy output.mp4

    What I want to achieve :
    Let's say that I have a folder which consists of several audio files : song-name-1.mp3, song-name-2.mp3, ..., song-name-n.mp3 and cover.jpg.

    I need a batch file which takes the name of every mp3 file in a folder (a FOR loop I suppose) and processes it with the same command :
    ffmpeg -i song-name.mp3 -loop 1 -i cover.jpg -r frame-rate -t song-length -acodec copy output.mp4

    So the image is always the same for every video. The song length can be taken with the tool mp3info and the corresponding command :
    mp3info.exe -p %S song-name.mp3

    Since I only have one image throughout the whole video, the optimal frame rate would be the inverse of the video length which is 1/length (where length is a variable in seconds which we get from mp3info).

    So the final code should look something like this :
    ffmpeg -i song-name.mp3 -loop 1 -i cover.jpg -r 1/length -t length -acodec copy song-name.mp4

    Where "song-name" is a variable which changes for every iteration of the FOR loop (i.e. for every audio file in the folder) and length is a variable whose value we get with the command :
    mp3info.exe -p %S song-name.mp3

    I found examples of a FOR loop to fetch all file names of all mp3's in a specific folder but I do not know how to integrate mp3info. I hope that somebody can help me and I have some knowledge of the C programming language if that can be used in any way.

  • Time interval between frames ffmpeg while creating thumnail

    9 février 2017, par rohit phogat

    I am creating a thumbnail sheet from videos inside a folder with 7 rows and 3 columns. I am using following command

    ffmpeg  -i "video.mp4" "ss.jpg" -frames 1 -q:v 1 -vf "select=not(mod(n\,40)),scale=466:-1,tile=3x7"

    I am not getting desired output. It just create thumnail starting from 00:00:00 and finishes at like 00:01:00

    How can i get time interval of 60 seconds between each frame ?
