  • Streaming Encoded MPEG-4 live video from a web camera using RTP in C++

    6 mars 2017, par Maad A.Galil

    I have been working on building a video streamer from a webcam using RTP protocol in C++ language in Linux. I was able to use opencv to take frames from the webcam and send them frame by frame to a client app that shows those frames one by one using the same frame per second parameter.

    But that is mostly a MJPEG kind of transfer as the encoding used is JPEG encoding with a specific quality for each frame. However, I would like to use MPEG-4 encoding before transferring the video. After a deep search online I found out that ffmpeg is the best for such purpose. But the samples online mostly work through a command line interface to capture a webcam video and save it as a video file with the given encoding and format.

    What I am asking about here. Is there a possibility to encode the webcam "LIVE", and get byte data while encoding the camera stream. I would like to use those byte data to transfer it using RTP for example. And then I would like to decode the received byte data and show the video using opencv imshow function for example.

    I hope that I could explain my question clearly.

    Thanks in advanced,

    Yours,
    Maad

  • 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 ?)
