• flash/modules/global/app/ffmpeg.exe is Non-Executable

  30 octobre 2013, par Juan Rocamonde

  I cannot install dolphin. Always it returns back the same error :
  

  The following files have inappropriate permissions:
  flash/modules/global/app/ffmpeg.exe;

  
  And if I scroll down, I can se this :
  flash/modules/global/app/ffmpeg.exe -- Non-Executable
  And I made it executable, chmod777 and I didn't work, so I tried with chmod755 and all chmods with executable parametres. And it didn't work anyway.
  Help please ! I need to get this working asap, is for a business !
  Thanks people.

• Parsing NAL units using FFMPEG

  6 novembre 2013, par 2ndlife

  I am new to MPEG-4 and taking baby steps to learn it. I am using FFMPEG as reference.

  1. I understand that all mpeg-4 are encoded into NAL units and wrt to FFMPEG av_read_frame() function returns one NAL unit, Am I right ? Is frame a NAL unit ? (though it can be a combination of multiple NALs)

  2. I also saw that h264_parser.c implements a function called h264_parse which is calling parse_nal_units() inside, If i need to get NAL units how can I use this parse_nal_units from my main function ?

  3. What is av_parse_Parse2() function do ? does it return decoded NAL units ?

  4. OR FFMPEG has -vbsf h264_mp4toannexb switch to dump raw NAL units, Can somebody help me understand how I can use the same from my main function ?

  Please help me out here...

• 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.
