  • Issues combining 2x mp4 h264 AAC video files

    13 avril 2018, par russt93

    We have two video files : -

    mainfile.mp4
    s1.mp4

    https://www.dropbox.com/sh/81ni6ll1g1sbpjl/AADxio80hgNepNtDyF9mNrK1a?dl=0

    (link to files above)

    We need to combine these two files together WITHOUT re-encoding,

    we CANNOT change the codecs or audio channels of the mainfile.mp4 (captured from an Axis camera).

    we CAN change as much as required in s1.mp4

    basically we have a video file mainfile.mp4 but we need to be able to insert s4.mp4 at the start WITHOUT re-encoding (it needs to be a quick process, we know we can probably re-encode but speed is the problem). We already know how to combine these files with a piece of software or if you can tell us how to do it with FFmpeg that would be great too.

    we need to how to create an s1.mp4 video file that is compatible for joining to s4.mp4. (to a single mp4 file with s1.mp4 at the start and then mainfile.mp4 to follow it). if you can tell us what software and settings to use as we’ll need to make different s1.mp4 files in the future.

    • the combined video must play on IOS and Android

    We can get the videos to join and play on andriod phones at the moment, on iPhones/IOS however the video doesn’t play for the second part (main.mp4), the combined video file must be capable of playing on Andriod and iPhones/IOS. Our current process will not currently play on iPhones/IOS. We’re guessing it’s because the videos are different somehow (codecs ?) they are both h264 with AAC audio but the video doesn’t work once joined on IOS/iPhones =(

    We’re guessing there is something wrong with the file the Android phones compensate for iPhones don’t like ! Some difference in the files ?

    We’re tried various frame rates and audio channel work but we are stuck !

    Looking forward to some help, we’d really appreciated !

    Thanks.

  • FFMPEG Compilation and Video Thumbnail Issues [on hold]

    2 janvier 2016, par P. Paul

    I have compiled FFMPEg on a Linux, Centos machine according to the guide in here https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu , and the auto video thumbnail creation command in here https://trac.ffmpeg.org/wiki/Create%20a%20thumbnail%20image%20every%20X%20seconds%20of%20the%20video

    The problems are...

    1- When I use ffmpeg or ffmpeg -version command to check if ffmpeg has been installed I get the error message, "Command not found". But when I check for ffmpeg directory "~/ffmpeg_sources" is found and the machine says, "is a directory".

    2- Also, I did a test and upload video to the site to see if the video’s thumbnail will be automatically generated, but it didn’t show any thumbnail.

    Any help would be greatly appreciated.

    Thanks in advance !
