• open source CMS and server for video streaming platform

  30 mai 2016, par Infinite

  I have to propose a platform that allows streaming video services employing the MPEEG-DASH standard. This platform blocks must be implemented with open source tools. I proposed FFmpeg to encode and MP4Box/GPAC tool for encryption and packaging. For the DRM case my propose is to use Widewine (I didn’t find any other open source tool) which is compatible with dash.js (the player proposed by me), it can be integrated to Chrome and according to CastLabs it’s also compatible with MP4Box. So, I have to select an open source CMS, and at the same time I need it to be compatible with dash.js. I read that it’s possible to add any JavaScript to these CMS, that it’s only necessary to create some modules to do so. I’d like to know which one of the following CMS you suggest me : MediaDrop, Drupal or Wordpress.
  I also have some doubts about the server. I know that in order to offer this service it only takes a traditional HTTP server. In a first moment I chose Nginx over Apache because the latter presents some problems associated to performance (the server will receive a large amount of simultaneous requests), nevertheless, I discarded Nginx (Nginx-rtmp module) due to its constraints : it’s only for live streaming (I need the service to be offered also on demand) and the inputs must be RTMP. I found something about Nginx-based VOD packager, do you know if this one can be used as a server to offer live and on demand streaming service ?

• Open raw audio with avformat_open_input

  15 novembre 2019, par IMelker

  I want to fill ffmpeg.formatCtx for raw(LINEAR16,48000khz) audio file using avformat_open_input().

  I’ve tried to pass own AVInputFormat, but not suceeded in it.

  This is how i used to open file.

  std::string fn = "file:" + this->file.path;
  
  int r = avformat_open_input(&ffmpeg.formatCtx, fn.c_str(), nullptr, nullptr);

  Tried to find needed format with av_find_input_format(), but not succeeded to0.

  Without input format ffmpeg determines file as mp3.

  Is there convenient way to do such case ?

• AForge.NET ffmpeg codec open error on Windows

  5 octobre 2017, par MTsuchi

  I often get the below ffmpeg codec open error while I run the WPF application that I create using AForge.NET. I need to save videos from a few USB cameras simultaneously through multiple threads. I get the error after I record videos several times. If anyone had solved a similar issue and gave me some ideas to solve, I would appreciate it.
