  • I Need Help Making Our Driver Station Video Feed Faster [closed]

    30 mars, par Joshua Green

    I am currently using FFmpeg on a Raspberry Pi 4 Model B using an ArduCam UC-844 Rev. B as the camera. We do not need any audio and I don't care about the quality of the video. All we need is for the stream to be as fast as possible. The video from the camera is being streamed to the driver station via FFmpeg and being picked up on the driver station via FFplay. Right now we are getting a delay that we wish could go away or be significantly shortened. These are the commands we are using.

  • What is a good/simple way to obtain a stream of song metadata from an online radio station ?

    29 juin 2022, par esp

    What is a good/simple way to obtain a stream of song metadata (artist names and song titles etc.) from an online radio station ? Just the metadata, not the data (media). On bash command-line for now, thinking of getting it to a database (eg MySQL) in future.

    


    I have had success using FFMpeg to do this (simply FFMpeg -i <streamurl></streamurl>). However it only reports the song playing once - when it is run. If I specify an outputfile (e.g. -f null -) then it continues to run but does not report any updates to the "now playing" metadata. If I do not specify an output file then, after reporting that metadata, it quits (which in my case is more useful !).

    &#xA;

    I can imagine one way round this would be to make a polling-loop, say every 10 seconds, only reporting when the metadata has changed (since the previous time). Does anyone have a battle-tested example ?

    &#xA;

    But is there a better (or cooler way) to achieve this ?
