Well gentoo needs you to chose ffmpeg or libav for update deep worlds to work. My system was moaning that libav + ffmeg were blocking each other.

The error is something like this :

[blocks B ] media-video/ffmpeg ("media-video/ffmpeg" is blocking
media-video/libav-0.8.2)

* Error: The above package list contains packages which cannot be
* installed at the same time on the same system.

(media-video/ffmpeg-0.10.2::gentoo, ebuild scheduled for merge)
pulled in by media-video/ffmpeg required by @selected

(media-video/libav-0.8.2::gentoo, ebuild scheduled for merge) pulled
in by
>=media-video/libav-0.8.1[X,encode,-jpeg2k,-mp3,-sdl,-theora,-threads,-truetype,-vaapi,-vdpau,-x264]
required by (virtual/ffmpeg-0.10.2-r1::gentoo, ebuild scheduled for
merge) 

I decided to use libav. Which appears to be the more active and stably developed.

I simply added -ffmpeg to my USE flag in /etc/portage/make.conf.

E.g :

USE="$USE -ffmpeg" #use libav

Then I removed ffmpeg from my system

sudo emerge -C media-video/ffmpeg
sudo emerge -C virtual/ffmpeg

Next was the big emerge

sudo emerge -avuDN world

which now no longer moans about blocking packages.

I used to have all my videos on my website as divx or xvid encoded AVI. This is a pain as you have to download the files to play them.

I found FlowPlayer and it works really well. I used to use flvtool to encode videos as flv files but it is not part of gentoo and I had to keep manually downloading and building it all the time to get the updates.

I recently found this article which shows how to use ffmpeg to encode videos as flv files.

ffmpeg -i video.avi -ar 22050 -ab 32 -f flv -s 320x256 video.flv

I then use the flv with FlowPlayer like this

<object type="application/x-shockwave-flash"
    data="/include/FlowPlayer.swf"
    width="320"
    height="284"
    id="FlowPlayer1">
  <param name="allowScriptAccess" value="sameDomain" />
  <param name="movie" value="/include/FlowPlayer.swf" />
  <param name="quality" value="high" />
  <param name="scale" value="noScale" />
  <param name="wmode" value="transparent" />
  <param name="allowNetworking" value="all" />

  <param name="flashvars" value="config={
		autoPlay: false,
		loop: false,
		initialScale: 'scale',
		showLoopButton: false,
		showPlayListButtons: false,
		playList: [
			{ url: '/media/tux_07.flv' }
		]
		}" />
</object>

See Hintertux 2007 for an example.

Well, this is crazy. We are back from Hintertux and now its time to start processing the video. My new Helmet cam means that I have loads of footage. 57Gb of raw dv files.

I have started watching the clips and chopping them up into little clips in Cinelerra. Its really a very good application. In my opinion its better than most. The motion tracking and stabilisation is really good.

download hard boiled online download bug s life a movie I did have one problem and it didn’t really like using the XVID AVI files which my helmet camera made so I converted all the files to raw DV files. I used ffmpeg to do this.

fairytale a true story dvdffmpeg -i video.avi -target pal-dv video.dv

I’ve been processing for days already and I still haven’t processed half of the footage.
