DATV: How to encode in h.265 with an external HDMI encoder

Intro

In my last article dedicated to amateur digital television, I had the opportunity to present step by step how to make your first DATV picture broadcasts. In this new article, I propose to focus on the implementation of a small box, an H.265/H.264 video encoder. It offers the possibility to those who are equipped with a computer without a “modern” graphics card unable to encode in H.265 to still be able to transmit with this H265 “compression”.

In this article, and as usual, we will go step by step through all the operations described as precisely as possible. This article is “multi-page”, to browse from one page to another or directly from the contents page to the desired page.

  1. Merci pour ce guide.
    Concernant la mise à jour des fichiers système par la clé USB, il faut un hub dit “OTG”, dans mon cas j’utilise un HAMA Hub USB 2 OTG (ou un hub standard + un câble OTG). Il semble également que le disque USB se monte pas automatiquement forcément sous /media/sda… Sur mon Pluto, il apparaît sous /media/sda1.

  2. Greetings from New Zealand.

    I notice that you have done some work with this inexpensive h264 encoder.
    I have been trying to find out if it can encode 1080i50 as well as 1080p50
    Would this be something you could test? It seems to be very difficult to find.

    Best Regards,
    Stuart.

    Salutations de la Nouvelle-Zélande.

    Je remarque que vous avez fait un peu de travail avec ce codeur h264 peu coûteux.
    J’ai essayé de savoir s’il pouvait encoder aussi bien le 1080i50 que le 1080p50
    Serait-ce quelque chose que vous pourriez tester ? Il semble très difficile à trouver.

    Bonne chance,
    Stuart.

    1. Stuart,
      Here is a capture where we see that the output is indicated 1080p. Concerning the input I have no way to test the variant. I use a notebook, and I have no other source available. Sorry for the poor help.

      Stuart,
      Voici une capture où l’on voit que la sortie est indiquée 1080p. Concernant l’entrée je n’ai pas moyen de tester la variante. J’utilise un notebook, et je n’ai pas d’autre source disponible. Désolé pour le peu d’aide.
