    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Quick stream from file which exists

    4 mai 2017, par parsa

    I implement live streaming from mp4 video file which exists on the path with ffmpeg under hls format.
    When my video file have the quality greater than hd720 , in encoding there are so many delays for creating .ts fragments.
    I mean the .ts fragments slowly produced on my path,and because of it I have so many delays in showing the stream.
    Here is my ffmpeg code for streaming :

    ffmpeg -re -i 123.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac 200p/out.m3u8 
    
              -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac 360p/out.m3u8 
    
              -s hd480 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 480p/out.m3u8 
    
              -s hd720 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 720p/out.m3u8
    
              -s hd1080 -f hls -hls_list_size 0 -c:v libx264 -c:a aac 1080p/out.m3u8

    And here is the console output :

        ffmpeg -re -i ../files/412-887123464/video/412-887123464.mp4 -s cga -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../fil
    
        es/412-887123464/video/200p/out.m3u8  -s nhd -f hls -hls_list_size 0 -c:v libx264 -c:a aac ../files/412-887123464/video/360p/out.m3u8 -s hd480 -f hls -

  • How reset PTS while converting with FFMPEG

    15 juin 2017, par Qianliang Zhang

    While converting *.ts file with ffmpeg, I want to set the start pts to be 10, or other pts. How can I do that ?

    Some people said setpts can help. I tried, but failed. Maybe my command is not correct, so what is the correct way ?

  • FFMPEG Force overwrite

    22 juillet 2017, par scripter78

    I have a C# application calling FFMPEG. Everything is finally starting to work except some people have uploaded different file types with the same name. example being video.mpg and video.mov. FFMPEG is taking the original files and creating a MP4 file out of them with the same name.
    of course when the first file is created it works fine but the second file is created and it requires interaction by me typing "Y" and hitting enter. is there a force overwrite option or a force rename option ?
