    14 July 2010, by

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 video/mp4 (...)

  • FFmpeg HLS save original timestamps

    11 July 2016, by Ivan Kolesnikov

    I transcoding a video to HLS and everything works fine with the following command:

    ffmpeg -i source -vcodec nvenc -acodec copy -f ssegment -segment_list playlist.m3u8 -segment_list_flags +live -segment_time 60 -segment_list_size 10 out%03d.ts

    But when I want to save an original timestamps and add -copyts key to my commnad then I received new .ts file each 0.7 seconds(but I set it to 60 seconds -segment_time 60).
    How can I save an original timestamps with transcoding to HLS ?

    UPDATE: I tried this command and timestamps are saves fine: 

    ffmpeg -i source.ts -vcodec nvenc -acodec copy -f hls -hls_time 10 -hls_list_size 5 -copyts playlist.m3u8

    But when I trying run this command for RTP input stream then I receive the following error: "Error while opening encoder for output stream #0:2 - maybe incorrect parameters such as bit_rate, rate, width or height".

  • How to dynamically save a video with ffmpeg without stopping recording?

    11 January 2023, by MP_95

    I am trying to save a video using ffmpeg with image input from an http webservice. I was able to create the video with the command:
ffmpeg -i http://source -c:v libx264 -r 30 -preset ultrafast -updatefirst 1 -y output.mp4.

    


    However, the video is only actually made available when I stop recording.
Is there a procedure that would allow me to have the video available while recording as is the case using OpenCv's VideoWriter
