  • how to use the H264 video encoder with ffmpeg / opencv2 ?

    30 août 2023, par Vince

    I am on ubuntu 22.04.

    


    I installed ffmpeg with apt.

    


    I am creating a video from some image files using python/opencv2 (installed via pip)

    


    When I use :

    


    cv2.VideoWriter_fourcc(*"mp4v")


    


    the video is successfully created, but is not supported by firefox.

    


    I read online that the H264 encoder would be a better fit for web-browsers supports.

    


    ffmpeg -codecs | grep h264 


    


    shows :

    


    


    DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (decoders : h264 h264_v4l2m2m h264_qsv h264_cuvid ) (encoders : libx264 libx264rgb h264_nvenc h264_omx h264_qsv h264_v4l2m2m h264_vaapi nvenc nvenc_h264 )

    


    


    but

    


    cv2.VideoWriter_fourcc(*"h264")


    


    results in :

    


    


    OpenCV : FFMPEG : tag 0x34363268/'h264' is not supported with codec id 27 and format 'mp4 / MP4 (MPEG-4 Part 14)'

    


    


    I could not find online what was wrong (h264 is not installed, how to install it ? the 'fourcc' of h264 is not 'h264' ? I should not create a *.mp4 file ?)

  • Python : movie stream into pygame

    4 mars 2019, par user1533267

    Quick challenge :

    I’m streaming part of my desktop screen trough the network using the following :

    Server

    $ ffmpeg -f x11grab -s 800x600 -r 30 -i :100 -an -q 10 -f mjpeg - | nc -lp 5000

    Client

    $ nc <computer address="address"> 5000 | ffplay -
    
</computer>

    I would like to display the following stream inside my pygame opengl window on the client, I read some documents on pygame.movie and found :

    "Load a new MPEG movie stream from a file or a python file object."

    Would it be possible to load the stream into pygame ?
    I need it to be as responsive as possible, and right now im seeing about 500ms lag.

    Any ideas ?

    Thanks.
