  • ffmpeg on the fly switch video from rtsp stream

    31 juillet 2021, par John Williamson

    I have a nest doorbell which provides a video stream via rtsp but for security the url is valid for just 4 minutes at which point a new url is provided i.e.

    


    15:25 - rtsps://stream-eu1-delta.dropcam.com:443/sdm_live_stream/CiQA2.....
15:29 - rtsps://stream-eu1-delta.dropcam.com:443/sdm_live_stream/vY8pB.....


    


    I'm able to play the individual streams to a rtsp-simple-server using

    


    ffmpeg -nostdin  -i  rtsps://stream-eu1-delta.dropcam.com:443/sdm_live_stream/CiQA2.... -q:v 1 -f rtsp rtsp://localhost:8554/live


    


    But is there any way to switch to the latest url on the fly ? I've looked at ffmpeg concate but this requires files. I don't really care about freezing or black between the switching, only that the output stream should remain open.

    


    ffmpeg version 4.2.4-1ubuntu0.1 running on Ubuntu 20.04.2 LTS

    


  • speeding up x264 encoding (C++ code with libavcodec)

    20 décembre 2012, par Hrishikesh_Pardeshi

    I am trying to capture windows screen (continuous screen shots) and encode them into x264. For that I am using avcodec_encode_video2 function available with libavcodec. However, it takes a huge amount of time. The time fluctuates between 25 – 1800 milliseconds for encoding individual frames.

    I tried tried both 1080p and 720p with video recording on screen.

    These are the settings I am using. This was tested on Windows 7, win32 release build with 4 GB of RAM.

    bit_rate = 2000, width = 1920, height = 1080
    qmin = 0, qmax = 0, max_b_frames = 0, frame_rate = 25, pixel_format = YUV 4:4:4.
    The remaining settings are default which are fetched using avcodec_get_context_defaults3().

    Sample data(in milliseconds) for 20 frames (consecutive and chosen randomly) in a set of 250 frames.
    121, 106, 289, 126, 211, 30, 181, 58, 213, 34, 245, 50, 56, 364, 247, 171, 254, 83, 82, 229

    For the application it is a must that it captures at least at 15 fps. Can someone help out to tell whether any options can be used to improve the frame rate. I need to encode lossless, but I am open to some file size increase.

    Thanks in advance.
