• Problem using -to, combining -to with framerate change

  21 avril 2019, par LLL

  I have a question regarding the use of the -to option :

  In FFmpeg version 3 (at least 3.2.12 included in Debian 9), -to was an output only option. In more recent version it seems to be accepted as an input option as well (as written here https://www.ffmpeg.org/ffmpeg.html#Main-options) but I run into limitations when using in conjunction with -r.
  What I expect, if I increase the framerate of the input, is that the output will be shorter. But it is not the case if I’m not using the whole input :

  ffmpeg -r 30 -to 10 -i my18fpsFile.avi out.mp4

  out.mp4 will be 10 seconds long, so the input has been read further than 10 seconds in.
  In other terms, even as an input option, it seems to behave like an output option.

  Tested with ffmpeg version N-48102-g7cab5471b2-static https://johnvansickle.com/ffmpeg/ on Debian Stretch.

  Thanks for your advice or confirmation that this is not normal.

  Edit : Thank you Gyan for your reply and your explanation.

  While it seems to work, some testing makes me remember why I wasn’t satisfied with this solution :
  Stating -r as an input option forces the framerate for the reading of the input and ensures one frame in the input is one frame in the output. This is what I want.

  Using yours solution with the filter on the output does cause dropped frames sometimes (which I have never had with -r).
  However, some more testing draws me to the conclusion that the dropped frames problem happens only with an mkv container ! Your solution works fine with other containers (as far as I have tested), but with mkv (and various video codecs, it doesn’t seem to make a difference), I get a lot of dropped frames.
  Using -r with mkv causes no dropped frames.

  In conclusion, I’m not sure how to generalize this solution, as avoiding mkv is annoying for me.
  But thank you, and if anyone has some more experience or ideas, please chime in.

  Adding logs :
  Note the line :
  [avi @ 0x6cf6880] parser not found for codec rawvideo, packets or times may be invalid
  I guess it is the cause of the problem ? Is there a solution if the files are raw avi with no index ?

  Although the warning is the same, I don’t get dropped frames if I use the exact same command only with f.mov instead of mkv.

  ffmpeg -v 40 -to 10 -i f.avi -vf setpts=N/30/TB -r 30 f.mkv

• Mkv to Mp4 Converion using ffmpeg giving error

  17 avril 2019, par ashok patel

  I recently started to use Sony Vegas 13 which doesn’t accept MKV(mkv source file :-https://www.appsloveworld.com/2018/10/sample-mkv-video.html) file types so I decided to install FFMPEG to convert a MKV to MP4 which people say has almost no loss in quality, etc. However, when I try to convert a 900MB MKV file it returns a 0kb MP4 file.Image

  The line of code I use is "ffmpeg -i set.mkv -codec copy set.mp4"

  This is the error ? message I get

• How to install a Matomo premium feature

  31 janvier 2018, par InnoCraft

  You may have noticed over the last few months that many fantastic new features have been launched on the Matomo Marketplace. As some of them are paid premium features, you may wonder if the process to install them is straightforward, if you can test them before, and whether there is any support behind it. No worries – we’ve got you covered ! This blog post will answer some questions you may have about getting your first premium plugin.

  So why are there some premium features ?

  Researching, building, documenting, testing and maintaining quality products take years of experience and months of hard work by the team behind the scenes. When you purchase a premium plugin, you get a fully working product and you directly help the Matomo core engineers to grow and fund the new Free Matomo versions and cool features.

  However, it is important for us to mention that Matomo will always be free, it is a Free software under GPLv3 license and it will always be the same.
  Want to know more about this ? Check out our FAQ about why there are premium features.

  Can I test a premium feature before a purchase ?

  Absolutely. There are two ways in order to do that :

  1. InnoCraft Matomo Cloud
  2. Matomo Marketplace

  1. InnoCraft Matomo Cloud

  The easiest way is to create a free trial account (one minute of your time) on our Matomo cloud service. You will then have the possibility to test all the premium features during a 30-day trial period. No credit card is required.

  

  Every premium feature can be trialled for free on the Matomo Cloud

  2. Matomo Marketplace

  The second way is to get the premium feature from the Matomo Marketplace. We have an easy and hassle-free 30-day money back guarantee period on each feature. This means that if you are not happy with a premium feature and you are within the 30-day period, then you will get a full refund for it. Guaranteed !

  How to purchase and install a premium feature ?

  Step 1 : Purchasing the feature

  In order to get a premium feature, just add it to the cart :

  

  Once done, go to your cart and complete the checkout process to confirm the order.

  When the order is confirmed, you immediately get your license key on the order confirmation page. You also receive the license key by email.

  Step 2 : Activating the feature in your Matomo

  Now that you have received the license key, it is time to activate the plugin in your Matomo :

  • Log in to your Matomo and go to “Administration => Marketplace
  • Copy / paste the license key into the license field at the top of the page and click “Activate”

  

  • The key will now be activated and you will see a couple of new buttons.

  

  • To install the premium feature(s) you just purchased in one click, simply click on “Install purchased plugins”. Alternatively, you can scroll down in the Marketplace to the premium feature you purchased and click on “Install”. You can also download the ZIP file on https://shop.matomo.org/my-account/downloads

  And that’s it. The installation of a premium feature is as easy as copy/pasting the license key and clicking a button. Because one license key is linked to all purchased premium features, you only need to enter the license key once. The next time you purchase a premium feature, you simply click on “Install” to have it up and running.

  Updating a premium feature

  Updates for premium features work just like regular plugin updates. When there is a new update available, you will see a notification in the Matomo UI and also receive an email (if enabled under “General Settings”). To upgrade the feature simply click on “Update” and you’re done.

  Which support is provided for each of those premium features ?

  Premium features represent most of our day to day activity, so you can be 100% sure that we will do our maximum in order to answer any of your questions regarding them. To be 100% transparent, we often receive answers from our customers telling us how impressed they are by the quality of the service we are offering.

  Have any questions ?

  We are happy to answer any questions you may have so feel free to get in touch with us.

  Thanks !
