• FFMPEG inside conda shell , running c++

  20 novembre 2018, par albert1905

  I’m trying to run a c++ program that depends on ffmpeg library.
  Important to mention, I’m working on a distance computer, so I don’t have the entire permissions.
  So I created a conda shell, download ffmpeg-dev, so far so good.
  I’m trying to run the c++ I want and he doesn’t recognize the "libav*" libraries (which are part of ffmpeg).
  I read that the libraries suppose to sit in "/usr/include" (or soemthing like that), in order that

  # include <>

  will recognize the library, but I don’t have permissions to write to this directory, so I had to think about something else, so I copied all the libav directories from "anconda3/include" to my dir and manually changed all the #includes to the realpath.

  But now I’m getting this error :

  g++ mpegflow.cpp -o mpegflow -O3 -D__STDC_CONSTANT_MACROS -lswscale
  -lavdevice -lavformat -lavcodec -lswresample -lavutil -lpthread -lbz2 -lz -lc -lrt -Idependencies/include -Ldependencies/lib /nfs/iil/itools/em64t_SLES11/pkgs/gcc/4.7.2/.bin/../lib64/gcc/x86_64-suse-linux/4.7.2/../../../../x86_64-suse-linux/bin/ld :
  cannot find -lavdevice collect2 : error : ld returned 1 exit status
  make : *** [mpegflow] Error 1

  I understand the problem, But I have no Idea how to solve it.
  I’ll be happy for your help.
  Thanks.

• Customizing HomeKit (using HomeBridge plug-in or building custom app ?)

  5 mai 2019, par Fréderic Cox

  I am running HomeBridge on a RBPi3 and displaying my home accessories through an iPad hub running the Home app.

  I really like it but I’m missing some things like a big clock (The iPad is hanging on my kitchen wall with screen-on display most of the day), a summary of my Google Calendar and some other nice widgets. It is not possible to add those widgets to the Home app (typically so with Apple software .. :-)) but I’m looking for a solution to achieve this.

  I have two options (at least that’s what I think) :

  1) Build my own iPad using the HomeKit API where I can then customize the app appearance and add the widgets the way I want.

  2) Using HomeBridge FFMpeg camera plugin and creating a video stream containing a big clock and some calendar item titles.

  Option 1 is the most work but also provides the flexibility. Option 2 is easier but limited in functionality. Option 2 might also be a performance overkill to have a video stream ? The video stream would provide me with the advantage that the camera widget in HomeKit is pretty big and clearly visible from distance (the clock at least).

  What do you think is the best option and how would option 2 be achieved ? How can I set up a video stream from for example a SWF file created in Adobe Animate ? Or how to achieve this dynamic info inside a video stream ?

  Any tips are most welcome ! Thanks

• Evolution #4184 (Nouveau) : Ajuster le défilement de $.positionner(), notamment dans le cas d’un h...

  29 septembre 2018, par placido .

  Le repositionnement des fomulaires ajax est inadéquate si la partie publique dispose d’un header en position fixed. (le haut du bloc est masqué)

  Une solution souple serait de prendre en compte la valeur d’une variable (Jquery.spip.positionner_delta ?!) dans le calcul de la distance de scroll.

  Sa valeur par défaut reste à 0, donc ne change pas l’existant, mais ouvre la porte à des ajustements avec une simple affectation en javascript :
  

  Jquery.spip.positionner_delta = 60;
