• Texture bound to texture unit 0 is not renderable

  2 décembre 2018, par Trying_To_Understand

  I followed this tutorial https://github.com/phoboslab/jsmpeg. I have an open wesocket that gets the data. Sometimes, it’s take a long time to the ffmpeg (on a remote computer) to get the data from my ip camera, so I wrote a setTimeout function that waites for 10 sec to be "sure" that the ffmpeg getting the data from the ip camera. If I remove this setTimeout function this error will show up :

  [.WebGL-0000020CFA5C04D0]RENDER WARNING : texture bound to texture unit 0 is not renderable. It maybe non-power-of-2 and have incompatible texture filtering.

  This is my code for showing the stream to the client :

  this.dataService.getDataByParam(camera.CameraId.toString())
  
    .subscribe(
  
    (result: any) => {
  
  
  
      setTimeout(() => {
  
        this.ws = new WebSocket('ws://' + result);
  
        $(document).ready(() => {
  
  
  
          this.player = new jsmpeg(this.ws, {
  
            canvas: document.getElementById("canvas"),
  
            autoplay: true,
  
            audio: true,
  
            pauseWhenHidden: false,
  
          });
  
  
  
        })
  
      }, 10000);
  
    },
  
    (error: Error) => {
  
      this.streamErrorMsg = "Problem with the server, please try again after some time."
  
    });
  
   }

  How can i know for sure that the ffmpeg has connected successfully to the camera and started to convert the data on the client ? i want to avoid writting the setTimeout function.

  If any samples are still buffered when request_frame returns EOF, they
  
  won’t be returned currently.

• Audio clicks / cracklings with ffmpeg audio recording on mac os

  15 février 2023, par Specimen

  I'm having audio clicks on my ffmpeg audio recordings. If I record with OBS for example, the audio comes out just fine. This is what I put in the terminal :

  


  ffmpeg -f avfoundation -i ":0" test.mp3


  


  where 0 is my Soundflower audio device, which I found using ffmpeg -f avfoundation -list_devices true -i "", which returns :

  


  AVFoundation audio devices:
[0] Soundflower (2ch)


  


  Soundflower, my speakers, and the ffmpeg recording are all set at 48kHz.
There is another thread that states that this may be an issue with ffmpeg version 4.3, and to try to downgrade to 4.2 ; I tried to google how to downgrade on brew, but didn't find anything.
