• Grow your business and understand your conversion funnel with Funnels for Piwik

  14 décembre 2016, par InnoCraft — Plugins

  Hi, this is Tom from InnoCraft. The company of the makers of Piwik.

  No matter what type of website or app you have, whether you are trying to get your users to sign up for something or sell products, there is a certain number of steps your visitors have to go through. I bet the same applies to you.

  Have you ever wondered if your visitors or users actually follow that path in your website or app ? And wondered where you lose your visitors ? Where they maybe get confused ? Want to see when something is not working anymore ? Maybe you have a multi step signup form or onboarding process ? On every step you lose visitors and therefore potential revenue and conversions. It’s critical to know how well your visitors go through these steps, where they originally came from and where they go to when they drop off.

  If you are wondering about such things like we do, or want to drive your conversions and sales, we have something for you.

• ffmpeg QSV hardware encoder with x11grab screen capture

  11 janvier 2020, par Toby Eggitt

  I believe I have built ffmpeg with support for my motherboard’s Intel graphics processor chip, but I have not succeeded in showing this working in any way. My goal is to use it for screen capture (the ffmpeg I built does capture screen successfully using the software encoding, but this is far too slow to be useful—it manages about 12fps at a very modest quality).

  My main problem—I think—is that I don’t know how to use these encoders, the examples I found all fail, which makes me suspect that what I’ve built is broken in some way. However, I also have no idea how I can verify that I built this correctly, but the following are true :

  • The five components that I built to get to this all compiled without
    errors (they were libva, gmmlib, intel-media-driver, libmfx, and
    ffmpeg
  • The output of ffmpeg -encoders includes four encoders with _qsv in
    their names including h264_qsv
  • Most of the commands I have tried result in output of this form :

      [h264_qsv @ 0x55ef1dc72040] Low power mode is unsupported
  
      [h264_qsv @ 0x55ef1dc72040] Current frame rate is unsupported
  
      [h264_qsv @ 0x55ef1dc72040] Current picture structure is unsupported
  
      [h264_qsv @ 0x55ef1dc72040] Current resolution is unsupported
  
      [h264_qsv @ 0x55ef1dc72040] Current pixel format is unsupported
  
      [h264_qsv @ 0x55ef1dc72040] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.
  
      Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  I have the impression this thing might be fussy about many parameters of this sort but have no idea where to find out what it would like. Any suggestions at all, how to verify it, or better yet, how to issue a command that captures screen and encodes with the hardware, would be most welcome.

• Combine .dash video and audio segments to .mp4

  11 décembre 2019, par Mike Stevens

  I was able to download some dash video segments (youtube-dl was apparently blocked from downloading the .mpd and just downloading, concatenating as normal) and was hoping to combine/concatenate them so I could watch in VLC, perhaps using ffmpeg. I was able to download the relevant .mpd and .ismc files, so I have all of the DASH video and audio segments, as well as the .mpd and .ismc downloaded and in one folder.

  The video files are labelled as such

  video=869000.dash
  
  video=869000-0.dash
  
  video=869000-600.dash
  
  video=869000-1200.dash

  and the audio in a similar fashion

  audio=96000.dash
  
  audio=96000-0.dash
  
  audio=96000-96225.dash

  Would anyone know of a way to combine all of these into one watchable video file ? AdobeHDS used to work great for combining fragments, and youtube-dl cleary has some sort of method to do it, but neither works with this particular .mpd. I don’t believe concatenate in ffmpeg will work, when I try to do that, it initializes the first .dash file (audio or video), but stops there.

  When I try to put the .mpd file through ffmpeg, it returns "Failed to open an initialization section in playlist 0". I would’ve assumed this initialization was the video=869000.dash file though (which is the one segment file that ffmpeg does recognize) ?
