  • FFMPEG.How to get audio stream from video and save it to disk on C++ [on hold]

    27 avril 2018, par Pein

    I’ve found information about how to save video frames to the disk, but how to work with audio stream I can’t find any useful information. Maybe someone knows how to get the audio stream from video and save it to the disk

  • x86 : hevc_mc : save 1 gpr in epel filter loading

    x86 : hevc_mc : save 1 gpr in epel filter loading

    The 3*stride value stored in r3src can be loaded much later,
    
so use r3src instead of a dedicated gpr when possible.

  • Crop video by frame and save output as video

    3 avril 2018, par D_Corson

    I’m trying to resolve a question I had posted earlier (trying to only use FFMPEG) and am still stuck and hoping someone else has a solution.

    I have a video that I want to crop frame by frame with a varying locations to extract a region of interest. I can currently do this using moviepy which has been excellent, but I would like to try and solve this using only FFMPEG. The added constraints are that I would like to be able to crop the frame and put this in a new video without having to save the cropped images locally and compiling them.

    Thanks
