  • 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 ?)
