  • Batch Convert .264 files to any Video Format

    9 août 2022, par Reydan Gatchalian

    I've been trying to find a software that will batch convert .264 files to any video format. The source of the video files is from an IP Camera. I found a software from HiP2P Client that has a converter.exe but only converts 1 file at a time.

    I tried checking if it can be run in the Command Line and just pass parameteres but it doesn't. Then I tried referrencing the DLL files included on the application but I got the error below.

    


    enter image description here

    


    Then I found ffmpeg (version : 2022-08-08-git-56973eb687-full_build-www.gyan.dev) and tried different commands but to no avail.

    


    ffmpeg -f h264 -i A220806_000015_000029.264 -c:v copy libx264 -an dest.avi

    I also tried looking for libraries so I can develop it using C# but I still can't find a library that works.

    


    I also tried VLC just to play it but I can't even play the files.

    I tried with ffmpeg, but it seems to work only with text-based subtitles.

    5 août 2022, par Nandha

    I'm trying to convert a av3 format video into wmv format to allow it be playable in web browser. To do the conversion I'm using FFMPEG to create thumbnail & low res wmv file. But I'm getting the below errors. I have the AVHash for the video file as well.

    


    Video codec using MediaInfo
