20 septembre 2011, par albanxWith my server I encode videos from any format to mp4 with ffmpeg, for making play them with flowplayer on the web site. The problem is that videos buffering is not working. Video plays once it has been fully buffered (downloaded).

I have IIS7 web server with php. Any suggestions ?

Music Video Idiosyncrasies
18 juin 2011, par Multimedia Mike — GeneralSo I’m watching a fairly recent music video for a song named "XXXO" from an artist named M.I.A. when I’m suddenly assaulted by this imagery :
... and I enter nervous convulsions. You see, while this might seem to be an odd video effect to the casual viewer, to a multimedia hacker, it appears to be deliberately antagonistic. To anyone who has written a video codec, this scene looks like an entire casserole of video bugs, combining creeping plane offsets errors, chroma problems, and interlacing havoc. The craziest part is to realize that this is probably some kind of standard video effect / filter type. Upon a repeat viewing, I realized that the entire video sort of looks like an amateur video editor’s first week using video software.
Elsewhere in the video, a YouTube-style video frame vortex highlights the proceedings. I guess I need to come to terms with the fact that the ubiquitous player frame is just part of the digital Zeitgeist now :
Vintage Video Strangeness
I’m a long-time music video junkie but I have a tendency of examining them entirely too closely. I first saw Paula Abdul’s video for "Cold-Hearted" when I was just starting to understand multimedia technology and how it interacted with emerging home computers. Imagine how confused I was when I tried to make sense of the actions performed by our eMaestro "Chuck" whom Paula has instructed to "hit it". First, he hits a key followed by 3 quick strikes on a second key :
Then, the "start music" action is apparently bound to a particular key on the electronic keyboard :
Which kicks off the electronic metronome on the computer. Each identical-sounding beat quizzically maps to a different frequency transform :
a one...
and a two...
and a three...
I had no trouble believing things up to this point. But even though I didn’t understand what was going on with that frequency transform, I knew that it must have had something to do with the audio. And if the audio was the same, the visualization ought to be the same. Though, to be fair, I will concede that the first and third ticks pictured bear some mutual resemblance.
Anyway, the software is probably real even if the keyboard interaction was stylized. Can anyone identify the software ? What about the computer ? This is perhaps the best view the video gives us :
So, remember, don’t base your understanding of technology — or anything, really — on stylized media representations. Don’t even get me started on the movie "Sneakers." That had me confused about cryptography and computer security for many years.

How to get correct video dimensions
21 septembre 2011, par David542I've been using
ffmpeg -i
andmediainfo (CLI)
to get the dimensions of a video. Unfortunately, neither have been very good at returning the correct dimensions. This is especially true if the video has been modified since its initial export.What is the best way to get the correct dimensions of a video file ?
