  • PySceneDetect FFmpeg Not Available

    14 août 2023, par Dmitriy Pushkarev

    I already installed FFmpeg and this is available in terminal I can convert video and etc, but it's completely not available in PySceneDetect.

    


    pip installed FFmpeg-python and FFmpeg library and FFmpeg itself in system.

    


    PySceneDetect returns :

    


    ffmpeg could not be found on the system. Please install ffmpeg to enable video output support.


    


    I think trouble with path, but can't put path in PySceneDetect. I can use path to binary FFmpeg, only in ffmpeg-python library, like this and it's working

    


    This code working fine :

    


    Here i using only FFmpeg-python library

    


    stream = ffmpeg.input('vi0.mp4')
stream = ffmpeg.filter(stream, 'fps', fps=10, round='up')
stream = ffmpeg.output(stream, 'vi1.mp4')
ffmpeg.run(stream,cmd='./ffmpeg')


    


    But can't it to get work with PySceneDetect

    


    print(scenedetect.video_splitter.is_ffmpeg_available())


    


    return False

    


    split_video_ffmpeg(video_path, scene_list, show_progress=False)


    


    returns "ffmpeg could not be found on the system. Please install ffmpeg to enable video output support."

    


  • ffmpeg split video H264 stutters on Windows Media Player

    9 mars 2019, par Juan Foegen

    I am converting and splitting wmv and mp4 into new mp4 files. I am using ffmpeg to do the conversion with simply :
    ffmpeg -i inputfile.wmv -vcodec libx264 -ss 00:00:10 -t 00:00:15 outputfile.mp4

    So when I create my split video it plays fine on other video players, like VLC, but stutters when initially playing on Windows Media Player and even shows a blank screen for a moment and then after about 5 seconds, the video will play normally. If I then select play again without reloading, Windows Media Player will play the video fine, with no stuttering.

    If I REMOVE the start parameter when doing the conversion, then the resulting video will play without issues on all my players, INCLUDING Windows Media Player.

    I have tried changing the frame rate, the bit rate and altered different optimization options mentioned here - https://trac.ffmpeg.org/wiki/Encode/H.264

    I need the split video to play on Windows machines on Windows Media Player and on the web streamed using the video element. This is why I chose H264 codec and MP4.

    Has anyone had issues playing ffmpeg split videos using H264 codec with Windows Media Player ? I am using the latest version of ffmpeg. Anyone have any other suggestions on any different settings I could try to adjust ?

    Thanks

  • Possible to Combine Live m3u8 stream with PIP overlay from WebRTC source ?

    25 octobre 2015, par user1258530

    Can someone tell me what server-side technology (perhaps ffmpeg), one could use in order to :

    1) display this full-screen live-streaming video :

    http://aolhdshls-lh.akamaihd.net/i/gould_1@134793/master.m3u8

    2) and overlay it in the lower-right corner with a live video coming from a webRTC video-chat stream ?

    3) and send that combined stream into a new m3u8 live-stream

    4) Note that it needs to be a server-side solution - - - cannot launch multiple video players in this case (needs to pass the resulting stream to SmartTV’s which only have one video-decoder at a time)

    The closest example I’ve found so far is this article :

    https://trac.ffmpeg.org/wiki/Create%20a%20mosaic%20out%20of%20several%20input%20videos

    Which isn’t really live, nor is it really doing overlays.

    any advice is greatly appreciated.
