  • Homebridge camera ffmpeg : rtsp stream accessible with vlc but not with Home app

    20 mars 2023, par someone

    I can access the stream of my esp32 cam with vlc but it doesn't load in home app. Here is my config :

    


    {

        "name": "Homebridge 963D",
        "username": "0E:B6:BD:6E:66:9B",

  • Speeding Up H.264 Frame Loader

    9 avril 2021, par user14607943

    I have a set of videos, that are about 15 seconds each, in H.264 format. I'm currently using skvideo.io.vread to ingest and process these. Specifically, I'm looking to extract x frames per second, where for example x=1. Current, I have :

    


    import skvideo
gen = skvideo.io.vreader('video.mp4', outputdict={'-r':'1'})

for f in gen:
   "do stuff with frames"


    


    I'm running a Python Flask service with multiple workers, which accepts requests with video inputs. Unfortunately, due to high QPS, I'm having super high CPU usage, and I was hoping to find a faster way of ingesting the frames from these videos.

    


      

    1. Can the above code be optimized in any way to speed up the frame extraction. I think FFMPEG is already subsampling the frames upon loading, but I'm not entirely sure. I'm willing to compromise on the exact logic of how the frames are extracted, so long as I'm roughly getting 1-2 frames per second of video. I saw this question, and am actively exploring whether the CPU optimizations are enabled for FFMPEG.

      


    2. 


    3. Is there an alternative to skvideo that can potentially be faster, and possibly work better in my service ?

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

    this is my header information
