    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.

  • How to save video as memory stream to .m4s freagments ?

    13 septembre 2019, par Yehor Chankov

    Summary

    I have a video streaming application, that processes videos uploaded by a user and serves it back to the user. Previously a user had to wait until the whole video had been processed and could only access it after that. Now I want my users to be able to start watching a video as soon as the first fragment is processed.

    The main idea is that I have an mp4 file, that I upload in memory using python and store as a 4d numpy array. Then I divide it into separate chunks and process each chunk.

    Solutions so far

    All solutions that I found so far are based on the idea that a complete mp4 video file exists, so that m4s fragments can be created by dividing it.

    Expected result

    What I want to achieve is that after each chunk is processed, it gets saved from memory to disk as m4s fragment, that can be served to a user immediately via MPEG dash .mpd playlist that links to all these fragments on disk.

  • Save continuous RTSP stream to 5-10 minute long mp4 files

    20 janvier 2017, par Ruslan Sharipov

    How can I keep the flow (protocol rtsp, codec h264) in file (container mp4) ? That is, on inputting an endless stream (with CCTV camera), and the output files in mp4 format size of 5-10 minutes of recording time.

    OS : debian, ubuntu
    Software : vlc, ffmpeg (avconv)

    Currently this scheme is used :

    cvlc rtsp://admin:admin@10.1.1.1:554/ch1-s1 --sout=file/ts:stream.ts
    
ffmpeg -i stream.ts -vcodec copy -f mp4 stream.mp4

    But it can not record video continuously (between restarts vlc loses about 10 seconds of live video).
