  I am trying to figure out how to fix these errors :

  Error while filtering: Cannot allocate memory
  
  Failed to inject frame into filter network: Cannot allocate memory
  
  Error while processing the decoded data for stream #2:1

  Observation #1

  If I run the following command on stream #2:1 by itself :

  ffmpeg -i video1c.flv -vcodec libx264 -acodec aac video1c.mp4

  The files is converted fine with no errors.

  Observation #2

  Running MediaInfo on video1c.flv (stream #2) shows the following :

  Format: Flash Video
  
  Video Codecs: On2 VP6
  
  Audio Codecs: Nellymoser

  Any help would be appreciated in resolving this error.

  Update #1

  I have tried splitting the filter graph into two as requested but I receive the same errors :

  Error while filtering: Cannot allocate memory
  
  Failed to inject frame into filter network: Cannot allocate memory
  
  Error while processing the decoded data for stream #1:1

  However, I did discover something, if I try to bring up stream #1:1 mentioned above (video1b.flv) using VLC Media Player, I can hear the audio file but I cannot see the video and I receive this error message :

  No suitable decoder module:
  
  VLC Does not support the audio or video format "undf".
  
  Unfortunately there is no way for you to fix this.

  Update #2

  The above error was with the 32bit version of ffmpeg. I switched to a 64 bit machine and am now running the 64 bit ffmpeg version ffmpeg-20180605-b748772-win64-static.

  Now I no longer receive the following error :

  Error while processing the decoded data for stream #1:1

  But, I have a new error. About an hour into running it, I receive the following error :

  av_interleaved_write_frame(): Cannot allocate memory
  
  [mp4 @ 000000000433f080] Application provided duration: 3327365388930198318
  
  / timestamp: 17178820096 is out of range for mov/mp4 format

  I also tried first remuxing all the files as suggested and using those files to run the above command and that did not help. I still get the same error.

• Programming Language Levels

  20 mai 2011, par Multimedia Mike — Programming

  I’ve been doing this programming thing for some 20 years now. Things sure do change. One change I ponder from time to time is the matter of programming language levels. Allow me to explain.

  The 1990s
  When I first took computer classes in the early 1990s, my texts would classify computer languages into 3 categories, or levels. The lower the level, the closer to the hardware ; the higher the level, the more abstract (and presumably, easier to use). I recall that the levels went something like this :

  • High level : Pascal, BASIC, Logo, Fortran
  • Medium level : C, Forth
  • Low level : Assembly language

  Keep in mind that these were the same texts which took the time to explain the history of computers from mainframes -> minicomputers -> a relatively recent phenomenon called microcomputers or "PCs".

  Somewhere in the mid-late 1990s, when I was at university, I was introduced to a new tier :

  • Very high level : Perl, shell scripting

  I think there was some debate among my peers about whether C++ and Java were properly classified as high or very high level. The distinction between high and very high, in my observation, seemed to be that very high level languages had more complex data structures (at the very least, a hash / dictionary / associative array / key-value map) built into the language, as well as implicit memory management.

  Modern Day
  These days, the old hierarchy is apparently forgotten (much like minicomputers). I observe that there is generally a much simpler 2-tier classification :

  • Low level : C, assembly language
  • High level : absolutely every other programming language in wide use today

  I find myself wondering where C++ and Objective-C fit in this classification scheme. Then I remember that it doesn’t matter and this is all academic.

  Relevancy
  I think about this because I have pretty much stuck to low-level programming all of my life, mostly due to my interest in game and multimedia-type programming. But the trends in computing have favored many higher level languages and programming paradigms. I woke up one day and realized that the kind of work I often do — lower level stuff — is not very common.

  I’m not here to argue that low or high level is superior. You know I’m all about using the appropriate tool for the job. But I sometimes find myself caught between worlds, having the defend and explain one to the other.

  • On one hand, it’s not unusual for the multitudes of programmers working at the high level to gasp and wonder why I or anyone else would ever use C or assembly language for anything when there are so many beautiful high level languages. I patiently explain that those languages have to be written in some other language (at first) and that they need to run on some operating system and that most assuredly won’t be written in a high level language. For further reading, I refer them to Joel Spolsky’s great essay called Back to Basics which describes why it can be useful to know at least a little bit about how the computer does what it does at the lowest levels.
  • On the other hand, believe it or not, I sometimes have to defend the merits of high level languages to my low level brethren. I’ll often hear variations of, "Any program can be written in C. Using a high level language to achieve the same will create a slow and bloated solution." I try to explain that the trade-off in time to complete the programming task weighed against the often-negligible performance hit of what is often an I/O-bound operation in the first place makes it worthwhile to use the high level language for a wide variety of tasks.

    Or I just ignore them. That’s actually the best strategy.

• Evolution #4468 : Unification des CSS pour les boutons et les icônes

  14 septembre 2020

  Noté pour ajouter un a.bouton

  Il y a déjà des variantes .principal et .secondaire dans cette prop, donc il suffit de les reprendre (cf. captures et description messages précédents).

  Par contre la classe .bouton est déjà utilisée dans le bandeau d’ajout rapide :

  • .
    Donc pour les liens boutons, il faudrait soit limiter à la balise <a></a> → a.bouton { … }, mais c’est un peu sale. Ou alors trouver une autre classe pour le bandeau.

    Un dernier truc à régler aussi : dans les styles actuels il semble être prévu de pouvoir utiliser les classes .icone.horizontale sur les boutons d’action, c.à.d #BOUTON_ACTION{…, …, …, icone horizontale s-24}.
    Mais je n’arrive pas à voir quel résultat est censé être obtenu avec cette combinaison. Actuellement, ça à l’air pété, cf. captures.

    
    

    D’une part ça n’est mentionné nulle part dans la charte (du plugin dev), et de l’autre ça semble n’être utilisé qu’une seule fois dans la dist, dans la page controler_urls. Ailleurs je n’ai vu ça utilisé que dans la Fabrique (les boutons de suppression d’objet).

    Je suppose que le but c’était d’essayer d’afficher un bouton d’action comme une |icone_horizontale.
    Mais |icone_horizontale ça produit un markup très différent de #BOUTON_ACTION, essayer de finir de porter la classe .icone.horizontale sur ce dernier ça va être bien compliqué.

    Mais en fait dans cette prop, on peut déjà avoir des icônes facilement dans les boutons d’action, soit en utilisant une des variantes new, add, del, config, ou alors en mettant une image/icône à la main dans le label tout bêtement.

    Donc au final ça me semble plus simple d’arrêter de supporter la combinaison #BOUTON_ACTION + classe .icone : en l’état ça marche à moitié, c’est inutile avec cette prop, et ça fait un truc compliqué en moins à maintenir.
