Demande de création d’un canal
12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...) -

Issues with processing media on windows Azure
23 septembre 2015, par Ahmed MujtabaI have a website built on ASP.NET web forms that works as a media portal for users to upload videos. I’m using ffmpeg encoders to produce video contents to be streamed in the browser. I’m using the web deploy method to publish the site on the Azure server. The website get’s deployed properly however I get following issues in the live site.
-
Video never get’s encoded and published. I get some sort of error.
-
Video get’s published but the process of uploading and encoding the video is way too slow on the web server.
My project solution contains upload.ashx that handles the upload requests and makes the call to encode.ashx which is responsible for the encoding and publishing of the videos. I tried to remotely debug the site but the debugger never get’s to encode.ashx.
I was wondering if these issues can be resolved by having the website deployed with a VM ?
Script that uploads the video file :
var filesuploaded = 0;

python ff-mpeg not working on VM
2 août 2013, par BobI have two Windows 2008 R2 64 bit servers with two different host providers (GoDaddy and company B). My python script runs successfully on GoDaddy's server. It doesn't run successfully on the server with company B.
I installed the same software on both servers :
- Python 2.7 for Windows 32 bit
- NumPY module
- SetupTools
- EchoNest API for Windows
The company B server is giving me an error related to an executable called en-ffmpeg.exe that uses the python ff-mpeg module. The exact error message is
[dv @ 0x1449690]Can't determine profile of DV input stream.
C :\Music\song1.mp3 : Error while opening fileThe song.mp3 file exists. I installed the latest Windows updates on the server with Company B but still I get the error. I believe the error is because something is not configured properly on this server (missing libraries or drivers ?). However, I don't know what that is !
Please help :)

Cannot save animation in matplotlib : Windows permission denied
13 mai 2015, par VladimirI’ve been trying for a day long to sort this out, checking similar threads but with no success.
Stretch’s Cannot save matplotlib animation with ffmpeg helped with previous errors (I had ffmpeg path wrong), but I kept getting Access denied after fixing it.My ffmpeg binary is on
C:\ffmpeg\bin
A nice alternative would be to able to export gif files, but I keep getting an ascii error with imagemagick. I think both problems are related, so I wanted to sort out the ffmpeg first.
I think the problem might have to do with the fact I’m working with Canopy (in Windows 8 64bit), which pretty much hegemonized my path variable and broke some things along the way (e.g. I can’t open IDLE since I installed Canopy, didn’t tried to fix that yet). As I fixed things along the way I found at least 3 distinct path variables, all of which I updated : windows advanced settings path (set manually), windows console path (set via console with setx), and sys.path (set or checked at runtime), adding
";C:\ffmpeg\bin"
, where ffmpeg effectively is. Regardless I sort out the problem or not, I would like to learn which of these environment variables are relevant for what, I find it very confusing.The code is the following :
# -*- coding: utf-8 -*-
