  • ffmpeg - create video from images - has no audio in output video

    19 juillet 2013, par sameer

    1) I have created the few images from my original xyz.mp4 (using ffmpeg)

    2) I am again creating the video from the images but the output.mp4 does not have the audio.

    I use the following command to create the video from images.
    ffmpeg -b:v 850 -r 10 -i out%d.png -s 640X480 -vcodec libx264 -sameq output.mp4

    Kindly let me know the the way for following steps

    1) create images from video (.mp4)

    2) create video(.mp4) from those images ( with audio in output file)

    Thank you.

  • Converting vídeo from vp8 to x264 outputs different video with different length

    25 octobre 2019, par Thomas Anderson

    I have a webm file (vp8 codec) with 2m:39s of duration

    Using ffmpeg -i video.webm it says that the video have 15fps

    nput #0, matroska,webm, from
    ’video.webm’ : Metadata :
    encoder : Lavf54.17.3 Duration : 00:02:39.63, start : 0.000000, bitrate : 417 kb/s
    Stream #0:0 : Audio : vorbis, 44100 Hz, stereo, fltp (default)
    Stream #0:1 : Video : vp8, yuv420p(progressive), 320x240, SAR 1:1 DAR 4:3, 15 fps, 15 tbr, 1k tbn, 1k tbc (default)

    I tried to convert setting to the same framerate and add to a mp4 container

    $ x264 --output intermediate.264 --fps 15 --preset slow --bitrate 400 --vbv-maxrate 800 --vbv-bufsize 1600 --min-keyint 48 --keyint 48 --scenecut 0 --no-scenecut --pass 1 --video-filter "resize:width=426,height=240" video.webm
    

    
$ MP4Box -add intermediate.264 -fps 15 out.mp4

    But the generated file out.mp4 now have a 2m:57s duration
