  • C++ ffmpeg real-time video transmisson

    27 janvier 2015, par Yonghao Zhao

    I am a student currently working on my final project. Our project is focusing on new type network coding research. Now my task is to do a real-time video transmission to test the network coding. I have learned something of ffmepg and opencv and have finished a c++ program which can divide the video into frames and send it frame by frame. However, by this way, the transmission data (the frames)size are quite much more than the original video file size. My prof advise me try to find the keyframe and inter frame diff of the video (mjpeg format), so that transmit the keyframe and interframe diff only instead of all the frames with large amount of redundancy, and therefore reduce the transmission data. I have no idea in how to do this in c++ and ffmpeg or opencv. Can any one give any advice ?
    For my old program, please refer to here. C++ Video streaming and transimisson

  • Raw numpy array from real-time network audio stream in Python

    10 avril 2022, par Andrzej Pronobis

    I would like to get raw data (optimally as a numpy array) from a PCM network audio stream for which I have an URL. The goal is to analyze the signal from the network stream in real-time.

    



    There seem to be a lot of Python audio modules or wrappers around e.g. FFMPEG, but after quite an extensive search I am yet to find a single example of a complete pipeline.

    



    For those familiar with OpenCV, I am looking for an audio counterpart of the OpenCV VideoCampture class.

    



    Any suggestions of modules to look at or code code snippets welcome !
