La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...) -

FFMPEG and MSA1 Codec Issues when Converting WMV to MP4 Video
30 décembre 2023, par user136819I have a WMV video file (around 60 MB size, 01:23:00 length) and I'm running a Windows Server 2016 64-bit machine for testing.

As far as I know, this video file was recorded using Microsoft Live Meeting 2007 back in April 2010 and there is also an associated audio file (which I'm able to play).

I tried to play the video file on my machine using VLC player (latest update), however, I always see this weird MSA1 codec error :




So I tried to resolve this problem by downloading and installing the Combined-Community-Codec-Pack-64bit-2015-10-18, and using its MPC-HC 64-bit player to play the video...
I still couldn't get it to play ! Here are the logs shown by the MPC player :

Since that didn't work, I tried installing the Microsoft MPEG-4 V1/2/3 VKI Codec for ASF files and still couldn't get the players to play the video and saw the same errors as above !


As a final attempt, I tried to convert this video to MP4 format using FFMPEG (version from 2020). Even this failed. Here are the logs :

I wish to know, is there any other way I can convert this video to a more modern format so that I can play it on a modern machine and modern video player ?

What other codecs am I missing here ? (if so, where can I get them ?)

FYI, as mentioned earlier at the top, I'm only able to play the associated audio file...

I'm fairly new to all this stuff, so any help is appreciated.


Thanks in advance ! :)

Can't obtain information with ffmpeg to Smooth Streaming Manifest file
4 mars 2015, par AlbertoI’m trying to get details for a stream of protocol Microsoft Smooth Streaming, with ffmpeg tools (ffprobe and ffplay) but when I run the next command :
ffprobe -i http://b31282.cdn.telefonica.com/31282/Manifest
I obtain this :

what codec to specify to accessing my HDMI-to-USB adaptor, under Linux ? [closed]
14 mai 2022, par DavidA week or so ago,I bought a HDMI-to-USB adapter, to use to capture video
TV content from my TV's set-top box. (Xfinity, if it matters. Box generically is :
"XiD X1"...I have both the Pace and the Cisco models available here in this house.)


Specifically, here's the adapter I bought,from Amazon :
https://www.amazon.com/gp/product/B09FLN63B3


So, I'm fluent in both Windows (Win-11) and Linux (Debian 'Bullseye', on my chromebook).


The adapter does not come with any recommendations for what software/drivers to (try to) use, but I was prepared for that.
After some google searches, I decided to first try using the cmd-line
'ffmpeg' program, because I'm
quite familiar with that (excellent !) piece of open-source software !


So, after a day or two of (mostly) success recordings under Win-11, using
ffmpeg's Microsoft-based 'dshow' (aka 'DirectShow'), I decided to attempt to get
up to the same level of accomplishment on my Chromebook, under Linux, also
using 'ffmpeg'.


[Ok...a very brief explanation of 'mostly' successful. I'll
post another separate question here, about the specifics of my glitches,
using 'dshow' on Windows. But, essentially, when I try to record to a MP4
file, I get 2 scenarios of glitch : #1 : Suddenly, dropped packets surges up,
and I get "1000 dropped' yellow msg #2 : On other trials, I get '...contains
no image...'.) So, I figured I should first give a Linux a chance,
before spending more effort trying to resolve the glitches on Windows.]


My first snag, was learning that 'dshow' seems to be specific to 'Windows',
and thus ffmpeg is getting 'unknown' for my reference to 'dshow'. After more hours of 'guessing', I've finally learned/concluded that there are other things
(something call "DeckLink" is one such alternative ?) for Linux, but I'm unclear
what extra Linux packages might exist for ffmpeg support, or whether I will need to built a more complete 'ffmpeg' (e.g. from source code), to get things going under Linux ?


Is my device able to be accessed from some tools other than 'ffmpeg' ?
(e.g. VLC or Handbrake or whatever ?) more easily, on the Linux platform ?


[If I had to, I'd probably invest another $20-$50 in some other hardware
device that goes from HDMI-to-USB (USB-A/B), if it were ]


All ideas are welcome...(TIA)
