  • How can I encode a video in a MP4 container using OpenCV 2.4.10 ? (Win 8.1)

    24 juin 2015, par Angie Quijano

    I have been trying to encode a vector that contains images, in a MP4 video. I have tried to use a lot of FOURCC codecs for this purpose, but I have not been successful.
    I have achieved to encode my vector in a AVI video using as CV_FOURCC code this : CV_FOURCC(’X’,’V’,’I’,’D’), but I really need to obtain a MP4 video. I have tried the following FOURCC codes : MP4S, MP4V, XVID, DVIX, X264, H264, FMP4, and others than I can’t remember.

    My line of code is :

    VideoWriter(videoName, CV_FOURCC('X','2','6','4'), fps, outputSize)
    where videoName = "OutputVideo.mp4", fps = 47, outputSize = [4225x2030].

    I checked if I built my OpenCV with Ffmpeg support and I got this :

    Video I/O:
      Video for Windows:           YES
      DC1394 1.x:                  NO
      DC1394 2.x:                  NO
      FFMPEG:                      YES (prebuilt binaries)

        util:                      YES (ver 52.38.100)
        swscale:                   YES (ver 2.3.100)
        gentoo-style:              YES

      GigEVisionSDK:               NO
      DirectShow:                  YES
      Media Foundation:            NO
      XIMEA:                       NO
      Intel PerC:                  NO

    I don’t know what I’m doing wrong. Can anyone help me, please ?

    Sorry for my english.

  • FFMPEG : Error writing trailer of v%v/index.m3u8 : Cannot allocate memory

    7 avril 2023, par user3309447

    I wanted to convert one video track and 2 audio tracks to HLS by combining them.
That means, the HLS conversion has to be multi-bitrate and multi-language both.

    


    What do I want to achieve ?
I have to prepare an HLS stream for 3 resolutions, namely, 720px, 480px and 360px.
Also, there will be 2 audio tracks in the resultant stream, one English and another Hindi.
I am running the below command and getting the error as described below.
Can anybody help me out ?
