  • Why ffmpeg convert only the first frame of gif to mp4 [closed]

    3 juin 2020, par Jayvant

    Gif has 6 frames with 2 sec delay per each.
I used following command :

    



    ffmpeg -i input.gif -y -an anim123.mp4 -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2"

  • FFmpeg AVI to MP4 preserves sound, but not images [migrated]

    21 février 2013, par user1711384

    Working with FFmpeg at a conversion (any file to MP4 (H.264/AAC)) :

    ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null
    
ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1

    With MPEG and WMV file it's working. With two different AVIs it didn't work. Logfiles from path 1 aren't generated and output 1 is empty, output 2 of course generates an error.

    After removing -profile:v baseline in both commands, the video file is successfully generated, but it's not possible to play it in JW Player (sound yes, but no image).

    This is the result of the first command :

    FFmpeg Successfully Pushes Stream to Nginx RTMP but Unable to Play with ffplay or VLC

    


    I followed the tutorial below :tutorial

    


    to set up an RTMP server using Nginx, and successfully pushed a stream with FFmpeg.
Here is the nginx.conf file :

    


    rtmp {
        server {
                listen 1935;
                chunk_size 4096;
                allow publish 127.0.0.1;
                deny publish all;

                application live {
                        live on;
                        record off;
                        allow play all;
                }
        }
}


    


    and here is the console output from pushing the stream :

    But when I try to play the stream using ffplay or VLC, it gets stuck in a waiting state.
this is the console output :
