  • Extract motion vectors from x265 (HEVC) encoded video with ffmpeg/libavcodec ?

    28 mars 2018, par John Allard

    I know that one can extract the motion vectors from an h264 encoded via by first setting the flag

    av_dict_set(&opts, "flags2", "+export_mvs", 0);

    then you can query the side-data for the motion vectors by doing this

    sd = av_frame_get_side_data(frame, AV_FRAME_DATA_MOTION_VECTORS);

    When I looked online to see if you can do something similar with HEVC encoded videos, I wasn’t able to find any information. All I found was this by the definition of "AV_FRAME_DATA_MOTION_VECTORS"

    Motion vectors exported by some codecs (on demand through the
    export_mvs flag set in the libavcodec AVCodecContext flags2 option).

    The data is the AVMotionVector struct defined in
    libavutil/motion_vector.h.

    but there was no information on exactly which codecs export this motion vector information. How would I go about finding this out ?

  • How to track WooCommerce orders in Matomo

    3 janvier 2018, par InnoCraft

    According to several sources (datanyze.com, builtwith.com, …) 20% of all online stores are using the WooCommerce WordPress solution. As a result, we thought some of you would be interested in knowing how you can track WooCommerce orders in Matomo (Piwik) without getting a headache.

    What is WooCommerce ?

    Logo WooCommerceSome of you may not be familiar with WooCommerce. It is one of the most popular WordPress plugins allowing you to transform your website into an online store with a few clicks.
    The main advantages of WooCommerce are :

    • free of charge
    • highly customizable
    • easy to install
    • huge community

    The WooCommerce Analytics plugin for Matomo

    Tracking e-commerce websites is always challenging as there are so many things to be taken into consideration. However, the InnoCraft team (the professional branch of Matomo) has developed a premium feature in order to track all orders into Matomo (Piwik).

    The Matomo (Piwik) WooCommerce premium feature is straightforward and easy to install and configure. You can find the plugin settings in WooCommerce under “WooCommerce => Settings => Matomo” :

    WooCommerce Matomo (Piwik) settings

    Once done, you will see the data appearing in your Matomo (Piwik) when an order is completed :

    The InnoCraft team made sure the plugin will record all completed orders 100% correctly (eg. ignoring failed orders, not missing any completed orders). The plugin will even track orders of customers who use an ad blocker thanks to a server-side tracking technique.

    Is the WooCommerce Analytics plugin an alternative to my current Matomo tracking code ?

    No. The WooCommerce Analytics plugin only records orders and abandoned carts made through the WooCommerce plugin. It will not record any page views, events or other actions. If you are looking for a great WordPress plugin to insert the Matomo (Piwik) tracking code into your WP website, we strongly recommend WP-Piwik.
