• How I can receive MJPEG stream via RTSP with resolution more than 1080p

  21 septembre 2018, par chuchuchu

  There is a problem :
  When I get a video stream with a resolution of 1080 and below - everything is fine.
  But if I select a stream with a resolution higher than 1080 on the camera, an error occurs.
  FFMPEG :

  [mjpeg @ 0x7f5488003e40] [IMGUTILS @ 0x7f5494acb4f0] Picture size 0x0 is invalid

  If I open a stream in the player I get a disparate image :

  [mjpeg @ 0x7fd9f8043b20] error y=91 x=16
  
  [mjpeg @ 0x7fd9f8043b20] error dc

  I repeatedly recompiled and reinstalled various versions of the ffmpeg, the problem is not solved.

  I suspect that there is a restriction for video stream over 1080p, but I can not find any description or solution.
  And I found next string in rfc "RTP Payload Format for JPEG" :

  The maximum width is 2040 pixels.

  but it is dated 1998. I know for certain that this stream on the RTSP receives in the resolution I need, but I can not understand how.

  Please, tell me the way to the solution. I’m using Ubuntu 16.04 amd64.
  Perhaps there is an alternative way to receive a rtsp-stream without using a ffmpeg ?? Since all ways known to me are using ffmpeg.

• How do I fix HTTP 404 error message using FFMPEG command ? [on hold]

  18 décembre 2018, par Noob

  I am trying to download a video from this site (https://ffmovies.ru/film/night-school.kk6y4/16qmpp) and have tried using ffmpeg but it always returns an "HTTP Error 404 Forbidden." I’ve also tried using the wget command to consolidate all the ts files but that didn’t work either (I get the same error message). I am not on expert in this and was hoping someone out there can help me fix this problem. Here is the ffmpeg code that I inputed :

  ffmpeg -i https://cdn.mcloud.to/stream/sf:i0:q2:h5:p23:l1/vtYB9rGpyklG1sxXqgdmXg/1545238800/g/9/b/pj11w4/hls/480/480.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

  I have also attached a picture of the error message for reference. I really appreciate someone showing me what I am doing wrong.

  Cheers.

• The ultimate solution to knowing how your business is performing overall

  8 janvier 2018, par InnoCraft — Community, Plugins

  Would you like to know how your business is performing overall at a glance ? Guess what, you can now do this easily with Roll-Up Reporting.

  What is Roll-Up Reporting about ?

  Roll-Up Reporting is a premium feature which you can acquire through the Piwik Marketplace. Developed by InnoCraft, the professional company behind Piwik, this plugin will :

  1. Save you heaps of time and gives you completely new insights
  2. Make this process easy as pie
  3. Reflect the structure of your business or organization

  1 – Roll-Up Reporting does the maths for you

  Yes, you read it right. Compared to having to sum reports of multiple websites manually, you can get aggregated results for your business or departments instantly with a single click directly in Piwik. Not only does this save you heaps of time compared to doing this complicated work in a spreadsheet, you also avoid human errors. With this feature, you get a clear overview over all your websites, apps, and shops performances.

  For example, if you want to know which referrers bring you the most value across all websites, then you will get the answer in a report. Same results for e-commerce reports, actions, and other metrics.

  2 – Easy as pie, no tracking code involved

  The best part of this feature is that you do not need to push data through additional tracking code. The setup is simple and made through the UI of the plugin.

  3 – Roll-Up Reporting meets even the hardest requirements

  You can also create “nested roll-ups”. This feature allows you to create a roll-up consisting of several other roll-ups. With a nested roll-up, you can create a roll-up for each department in your company (and assign all the websites of a department to that roll-up), then group several departments easily into a new roll-up simply by assigning several department roll-ups to this new roll-up.

  

  For example, a company with multiple brands can assign multiple websites to each brand, and then get aggregated results for each brand and for the business overall. As a roll-up is basically the same as a website, you can give users access to a roll-up without having to give them access to each site, and the other way around.

  How does it work ?

  As with all premium features, this plugin is straightforward to use. Once activated in your Piwik administrator panel, you will notice that when you add a website, you have the choice between two possibilities :

  

  When you select the “Roll-Up” option, a new window will appear asking you which websites and mobile apps you would like to aggregate into a roll-up :

  

  The created roll-up will then be shown just like any other website that you have in Piwik. You can create as many roll-up entities as you want.

  

  Features, such as custom alerts, segments, and e-mail reports work for a roll-up just like for any website.

  Real-Time reports

  One of the most interesting features of Roll-Up Reporting is, that you can view all the Real-Time reports, such as the “Visitors in Real-Time” widget, the “Real-Time Map”, and the “Visitor Log” across several websites making it much easier to keep an eye on your business :
