  • vmd : decode videos with no LZ buffer size provided - they might not need it

    1er juin 2013, par Kostya Shishkov
    vmd : decode videos with no LZ buffer size provided - they might not need it

    The buffer is used for an additional pass of frame compression, so videos
    
can be coded without ever using it (and some are coded so indeed, e.g. in
    
Woodruff and the Schnibble of Azimuth game).

  • How to route FFMPEG screen capture output to Python for OpenCV processing ?

    16 décembre 2016, par Bitani

    I am trying to capture the screen of a Mac, specifically game windows, and process them in real-time using OpenCV. I currently have it working with pyscreenshot and a conversion to a numpy array, but the max framerate of this method, on any system, appears to be around 10 FPS.

    Obviously with games it would be very beneficial to be able to process 30+ FPS, and so I found that FFMPEG could record the screen using this command :

    ffmpeg -y -f avfoundation -capture_cursor 1 -i "1" -pix_fmt yuv420p -vf scale=1024:-1 -r 30 out.mp4

    That will write the screen to a file, out.mp4, with a width of 1024 and a frame rate of 30 FPS. Works perfectly ! But now I’ve searched and searched and searched for a method to route FFMPEG’s output to Python and.. no luck.

    If anybody knows of a way to do this I would be greatly appreciative, as I’ve been trying to solve this for quite a while !

    Thanks, and happy holidays !

  • how to combine an image stream and an audio stream together with transcoding

    11 novembre 2020, par SolskGaer

    I tried the method mentioned in this link to capture audio stream from an iPhone, and want to combine the audio stream with an image stream(10 fps) which can be acquired via http. But the output I got has messed up audio and the video speed is way faster than the input, here is the command I used to generate the video ffmpeg -f avfoundation -i ":4" -f mjpeg -i http://127.0.0.1:8888 -c:a aac -c:v libx264 out.mp4, how do I fix the problem ? By the way, when I transcoding audio/video only, it worked exactually as expected.
