• ffmpeg when asked to map a .mov file's streams 0,1,3 actually maps streams 0,1,2

  15 septembre 2023, par user2258729

  I'm trying the following :

  


  Start with in.mov which has 4 streams 0:0 - 0:3.

  


  Audio, Video, Data (unknown), and mJpeg.

  


  Trying to map 0:0, 0:1, and 0:3 into out013.mov.

  


  ffmpeg -i in.mov -map 0 -map -0:2 -c copy out013.mov

  


  or

  


  ffmpeg -i in.mov -map 0:0 -map 0:1 -map 0:2 -c copy out013.mov

  


  ffmpeg tells me that 3 streams are mapped :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:3 -> #0:2 (copy)


  


  ffprobe disagrees. According to it what really happened was :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:2 -> #0:2 (copy)


  


  "Who needs a thumbnail image anyways, screw it !" I said. "Let's just get rid of the data."

  


  ffmpeg -i out013.mov -map 0:0 -map 0:1 -c copy out01.mov

  


  ffmpeg tells me that 2 streams are mapped :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)


  


  ffprobe disagrees. According to it what really happened was :

  


    Stream #0:0 -> #0:0 (copy)
  Stream #0:1 -> #0:1 (copy)
  Stream #0:2 -> #0:2 (copy)


  


  Seems like I can't rid myself of that data stream (0:2).

  


  Below is the output from the ffprobe and ffmpeg for the first scenario.

  


  Any ideas ?

• 8 Best Tools to Analyse Website Traffic

  12 septembre 2023, par Erin — Analytics Tips, Marketing

  Do you want to analyse your website traffic ?

  Maybe you want to know how well you’re converting your traffic. Or maybe you’re looking to track the performance and ROI of your marketing campaigns. Regardless, you won’t get far without relying on a dependable web traffic analysis platform.

  In this article, we’ve compiled a list of the top web analytics tools available (including the pricing for each one).

  Let’s dive in.

  What is website traffic analysis ?

  Curious about what it means to analyse website traffic ?

  

  Simply put, it involves collecting and examining data about your website visitors and the actions they take. Marketers, analysts and website owners can then take this data and use it to optimise their strategy to improve site traffic, conversion rates and ROI.

  A website analytics tool is software that tracks and measures various visitor activities and behaviours on your website. Common metrics include pageviews, traffic source, bounce rate and average time on page. Using a web analytics solution can give you insights into what’s working (and what’s not working) so you can optimise your website, campaigns or marketing strategy.

  Advantages of using a website traffic analysis tool

  1. Performance measurement and optimisation

  Tracking the success of your marketing efforts is a challenging task. The primary benefit of using a web analytics tool is implementing effective performance measurement. If you don’t know how to measure your efforts, you won’t know what’s working and what’s not with your campaigns and content. 

  A web analysis tool can give you the insights you need to understand whether your marketing initiatives have been successful or if they need to be improved.

  For instance, your new web design facelift may seem beautiful, but if visitors aren’t staying on your site as long and it is resulting in lower conversions, then it’s time to go back to the drawing board.

  2. Audience insights to improve the user experience

  Web traffic analysis platforms don’t just show you what your visitors are doing. It shows you who your audience is. A powerful website analytics tool will give you in-depth audience data, including demographics like geographical location (e.g., city, state or country), to help you better understand your audience.

  Additionally, you can learn more about your audience by seeing how they interact with different content on your site. You’ll start to see that certain content performs better than others, giving you a greater understanding of your audience’s needs and wants. This means you’ll be able to tailor your website content and marketing efforts to your audience to improve the overall user experience.

  3. Improve SEO

  In the first two advantages, we touched on how insights can help you craft better content for the visitors already coming to your site to improve the user experience and improve conversions. But did you know that using a website analytics tool can also help improve how much traffic you’re getting to your site ?

  Since a web analytics tool can help you craft better content, one side effect is an increase in traffic from organic search through SEO. Additionally, your platform will likely show you other traffic sources that your visitors are coming from (i.e., another website is referring traffic to you) so you can tap into those high-performing sources and optimise your incoming traffic over time.

  Top 8 Tools to Analyse Website Traffic

  Here’s a breakdown of the top eight web analytics platforms to help you analyse each tool’s unique features, price, advantages and disadvantages so you can make the best decision.

• FFMPEG error submitting a packet to the muxer

  27 juillet 2024, par Badgio10177

  I am attempting to stream video frames to a RTSP server using FFMPEG. I instantiate an ffmpeg pipeline in c++. There are times when the process works perfectly and other times I get the error Error submitting a packet to the muxer : Broken pipe. Error muxing a packet. What uis strange is that there are times when the stream works and times when it does not which leads me to believe that the FFMPEG parameters that I set are not necessarily incorrect.

  


  I am using a mex function within MATLAB to take in a frame and stream it.

  


  // Global variables&#xA;FILE* openPipeLine = NULL;&#xA;&#xA;void mexFunction(int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[], int frameWidth, int frameHeight)&#xA;{&#xA;&#xA;    Ptr<mat> inputFrame = ocvMxArrayToImage_uint8(prhs[0], true);&#xA;    Mat processedFrame = *inputFrame;&#xA;&#xA;    // Check if FFMPEG process has been started&#xA;    if (!openPipeLine)&#xA;    {&#xA;        openPipeLine = _popen("ffmpeg -report -f rawvideo -r 10 -video_size 1280x720 -pixel_format bgr24 -i pipe: -vcodec libx264 -pix_fmt yuv420p -f rtsp rtsp://localhost:8554/mystream 2> log.txt", "wb");&#xA;&#xA;    }&#xA;&#xA;    // Write the frame data to the pipeline&#xA;    fwrite(processedFrame.data, 1, frameWidth * frameHeight * 3, openPipeLine);&#xA;    mexAtExit(exitFcn);&#xA;}&#xA;</mat>

  


  Below is the full report from the ffmpeg process. Do my operating system variables change from time to time which cause the stream to work at times and break at others ? I am using Windows 10.
