  • Create MP4 for HTML5 video with FFMPEG

    7 août 2013, par Kris

    I'm trying to create an MP4 file with FFMPEG to play with a HTML5 video tag.

    I found some sample codes that use libx264, but when I tried, FFMPEG gave me an "unknown encoder libx264" error.

    I asked my host to install it on my server, and got the following reply :

    After review from our L3 group I am informed that x264 is not supported with FFMPEG any longer. That was a library that went with FFMPEG-PHP that is not supported at all by anyone.

    In order to get that to work with FFMPEG you would need to contact the developers of the FFMPEG software to get assistance with that as it is outside our scope of support.

    I looked everywhere online, but can't seem to find an answer to this. If libx264 is not supported anymore, how is everyone else doing it ? Still libx264 with an older FFMPEG version, or some other way ?

  • Using Java and ffmpeg to most efficiently merge mp3 audio file and jpeg image file to a video file [closed]

    25 juin 2020, par Eugen

    I'm looking for an efficient way in Java to merge a large .mp3 file and a single .jpg image to a video format for youtube. If I use :

    


    ffmpeg -loop 1 -i image.jpg -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -b:a 192k -shortest output.mp4


    


    the result is very slow, especially for large .mp3 files. Is it possible to do it more efficiently with ffmpeg ? I know there must be a way to do it much more efficiently, like all the online converters are doing it.

    


  • Inserting an image inside a video every few frames using ffmpeg

    31 juillet 2023, par Erez Hochman

    Can I use FFMPEG to insert an image every 20 frames in a video ? 
I'm trying to create a subliminal message experiment and I thought it would be an easy way to make it but I can't find anything online.

    



    I tried to make something myself and created a script that :
    
1.splits a file into audio and video files
    
2.splits the video into frames
    
3.overwrites every 20th image in the sequence with the message image
    
4.re-encoding the video
    
5.concatenating it with the original audio

    



    this works but it's way more disk space consuming to be comfortable, is there a better way to do this ?
    
any advice or thought would be happily welcome.
