How can I encode a video in a MP4 container using OpenCV 2.4.10 ? (Win 8.1)
24 juin 2015, par Angie QuijanoI 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)
codec: YES (ver 55.18.102)

PvAPI: NO
GigEVisionSDK: NO

FFMPEG : Error writing trailer of v%v/index.m3u8 : Cannot allocate memory
7 avril 2023, par user3309447I 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 ?
