on MacOS Lion, using the heads of the trees, with direct encoding support for:
x264
vpx / WebM

A nice recent update to ffmpeg is the ability to decode/read Apple ProRes, too!

• x264
• ffmpeg
• mplayer

here, i’m making sure that i compile in static version of libvpx (Webm) and libx264 (h.264) video packages so that the ffmpeg can easily make hiqh quality h.246 and webm transcoded videos.

http://www.archive.org/~tracey/downloads/macff.sh

So we can make nice (2 pass video) ~768 kb/sec 640×480 derivatives like so (alter “-r ” as appropriate):

# make WebM
ffmpeg -deinterlace -y -i 'camels.avi' -vcodec webm -fpre libvpx-360p.ffpreset -vf scale=640:480 -r 20 -threads 2 -map_meta_data -1:0 -pass 1 -an tmp.webm


ffmpeg -deinterlace -y -i 'camels.avi' -vcodec webm -fpre libvpx-360p.ffpreset -vf scale=640:480 -r 20 -threads 2 -map_meta_data -1:0 -pass 2 -acodec libvorbis -ab 128k -ac 2 -ar 44100 tmp.webm


mv tmp.webm 'camels.webm'

# make h.264

ffmpeg -deinterlace -y -i 'camels.avi' -vcodec libx264 -fpre libx264-IA.ffpreset -vf scale=640:480 -r 20 -threads 2 -map_meta_data -1:0 -pass 1 -an tmp.mp4


ffmpeg -deinterlace -y -i 'camels.avi' -vcodec libx264 -fpre libx264-IA.ffpreset -vf scale=640:480 -r 20 -threads 2 -map_meta_data -1:0 -pass 2 -acodec aac -strict experimental -ab 128k -ac 2 -ar 44100 tmp.mp4


qt-faststart tmp.mp4 'camels.mp4'


our preset files:
http://www.archive.org/~tracey/downloads/libvpx-360p.ffpreset
http://www.archive.org/~tracey/downloads/libx264-IA.ffpreset

Nice things about the h.264 derivative:

• plays on all iphones and ipads
• browser video tag and/or flash plugin compatible
• starts immediately, seeks immediately even before entire video is downloaded

hope this may be useful!

I got this supercute mini-laptop last year

I had been using Ubuntu linux Lucid (10.4) and just upped to Meerkat (10.10). (Both were Netbook Edition).
I’d never gotten video acceleration to work before and was stuck w/ ~1-5 fps video most of the time.

Doing the widely suggested:

sudo add-apt-repository ppa:gma500/ppa && sudo add-apt-repository ppa:gma500/fix && sudo apt-get update && sudo apt-get install poulsbo-driver-2d poulsbo-driver-3d poulsbo-config


bricked my vaio 8-( well, i mean, it gave me root login w/o X/windows ability but… 8-p)
but 2-3 apt-get remove, reinstalls, hunting google later, found the apparent saviour (I did 1000mb from 2000mb recommended here):

sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash mem=1000mb acpi_osi=Linux"
sudo update-grub

booted clean! *immediately* got ability to use proprietary vaio accessory to output VGA to external monitor (a first!) and brightness up/down hotkeys working. (brightness to work even at all!)
but best of all, video and appearance *and everything* (moving windows, starting applications) was *so much faster* visually!

cmd-line video playback with:
sudo apt-get remove mplayer
sudo apt-get install gnome-mplayer gecko-mediaplayer

so this is *all* i have done, aside from starting w/ vanilla install (with just a few changes to help w/ SSD instead of HD) of lucid upgraded to meerkat.
(personally, i’m still working on getting suspend/resume to work (seems to work but the display doesn’t come back on — been like this the whole time) and to get hibernate to work — prolly will go with some kinda memory stick to dump to)

UPDATE!

suspend/resume working now with change to suggested “gma500 fix”

sudo add-apt-repository ppa:gma500/ppa && sudo add-apt-repository ppa:gma500/fix && sudo apt-get update && sudo apt-get install poulsbo-driver-2d poulsbo-driver-3d poulsbo-config

I think this additional suggestion may have fixed sleep/resume (but it’s possible it was just the gma500/fix related packages in live above:

sudo mv /usr/lib/pm-utils/sleep.d/99video /usr/lib/pm-utils/99video

So after over a year of owning this site w/ little more than 10 posts and pages geared towards AIDS LifeCycle fundraising and training, I’ve finally merged my personal site into this site and updated it.  So now this is the

New home of Tracey Jaquith and Dumb Bunny Productions.

I’ve got new a new navigation layout and structure, updated CSS and style, and about 20 main info pages added.  I’ll be tweaking it a bit, but the biggest changeover is now live!  This site aims to blend blogging with a more traditional website.
