    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • How to trim single ts file and concat with everything after with ffmpeg

    22 mai 2019, par user3321348

    I have a number of ts files (h264, AAC) and I want to quickly cut out a portion without re-encoding more than the first chunk and last chunk. Then I want to concat them back together and make an mp4.

    So I have 1.ts - 100.ts and each chunk is roughly 10 seconds. I want to cut from 1:05 to 10:05 minutes. I have code that finds the first and last ts file needed (let’s say it’s 11.ts for 1:05 and 61.ts for 10:05)

    I run this to trim the first ts file to only the portion I need :

    ffmpeg -i 11.ts -ss 5.0 -c:v libx264 -c:a aac 11.new.ts

    Roughly the same thing happens to 61.ts to create 61.new.ts.

    Now I want to concat 11.new.ts, 12.ts, 13.ts, ..., 61.new.ts into an mp4 without having to re-encode every single chunk. Currently, the resulting video plays the remaining portion of the first chunk just fine. After that point the audio continues but there’s no more video. I’m sure that has something to do with start time offsets that’s in the metadata of each ts file, but I can’t figure out how to solve that. Is this even possible ? And is this the best way to quickly do something like this ?

  • Too small ffmpeg rtsp decoding buffer

    30 janvier 2013, par gregoiregentil

    I'm decoding rtsp on Android with ffmpeg, and I quickly see pixelization when the image updates quickly or with a high resolution :

    working decoded frame

    non working decoded frame

    After googling, I found that it might be correlated to the UDP buffer size. I have then recompiled the ffmpeg library with the following parameters inside ffmpeg/libavformat/udp.c

    #define UDP_TX_BUF_SIZE 327680
    
#define UDP_MAX_PKT_SIZE 655360

    It seems to improve but it still starts to fail at some point. Any idea which buffer I should increase and how ?

  • What transcoding services can people recommend ? [closed]

    3 mai 2013, par Adrian Lynch

    A client of mine needs to accept a bunch of different video files and convert them to FLV. My experience with FFMEG on a previous project has highlighted that there will be some troublesome files.

    Depending on the price my client will pay for a professional service.

    What are people using and how are you finding the service ?

    Thanks.
