mplayer Video File Properties

michael — Fri, 16 Apr 2010 16:33:15 +0000

I was looking for some native 1080/720p HD media files and also comparing some lower resolution files played back on a new HDTV. Many times you can get some quick info on media file properties with the ‘file’ utility:

mshuler@gaea:~$ file Life.Of.Brian.1979.avi
Life.Of.Brian.1979.avi: RIFF (little-endian) data, AVI, 640 x 336, 25.00 fps, video: XviD, audio: MPEG-1 Layer 3 (stereo, 48000 Hz)

or not..:

mshuler@gaea:~$ file Three.Days.of.the.Condor.1975.mkv
Three.Days.of.the.Condor.1975.mkv: Matroska data

A quick look at the ‘mplayer’ man page gave me the options I needed to get all the properties without playback of the file:

mshuler@gaea:~$ mplayer -identify -frames 0 Three.Days.of.the.Condor.1975.mkv
MPlayer SVN-r30656 (C) 2000-2010 MPlayer Team

flickr!

I have grown tired of maintaining my gallery software locally (and lazy with uploading images..), so got myself a Pro Account and migrated all the existing images to the wonderful flickr. I will update the gallery link and tinker with blog integration – there are a few flickr widgets that might be just perfect

Valid XHTML YouTube Embedding

michael — Wed, 07 Mar 2007 20:33:14 +0000

I was checking validation on my pages and found the only XHTML errors were from the suggested YouTube embedding code. A quick search revealed several XHTML valid code examples, and here is what I am using to center the frame under XHTML 1.0 Transitional (this fails 1.0 Strict validation – to make this validate under Strict, just remove align=”center”..):

Update:
I am now using div’s to solve page formatting issues..:

Someone posted an article about Team Hoyt on Digg – this is truly inspirational, and I have not had a good cry like that in a while..

Old Photos

I stumbled across a photo CD that I had not uploaded to the gallery, so I put it in about the right place, based on the date. It was about August 2002, since we were in San Antonio, but had not bought our house, yet, and it was it was Emma’s birthday party.

Gallery Migration Done!

michael — Tue, 21 Sep 2004 08:53:25 +0000

The site and photo gallery have been migrated to a new server, and Gallery upgraded to the latest stable version. This is kind of fun for me because I am no longer on a shared server, but my very own. I have a couple of rolls of film to get developed, and will get them uploaded as soon as I can!

Words

Roxane,

Busy – busy! I have not had much time to write, here, but life is good! Roxane will be talking soon – she already has a good grasp of “bye, bye,” “no,” “mama,” “papa,” and mumbles a lot to us – she will repeat things, like we are supposed to understand. Mom and Dad were here last weekend, and Dave and Mel came down to eat dinner Friday night, then stay up late chatting, and waiting for Roxane to go to sleep… Here she comes, running into the office! I have spent a good bit of spare time installing a new server, and compiling PHP, netpbm and all the libraries needed for image manipulation, to run Gallery. I will get some time to update the text, sometime, unless there are any creative volunteers Let me know if you want a login, so you can upload images to the server, or if you want to help update the album and image tags. This is currently on DynDNS, so go to http://www.pbandjelly.org/gallery/ (now on this server) to see the gallery. Again, please let me know if you want a login to post to your own albums – the more the merrier!

Michael
