Hi all,
2 questions:
- Is there a way to load bitmap images into a patcher as a background image?
no idea how to do this, but it would be a nice thing to have.
- Using Gem with a Linux System I try to play back an Apple Quicktime Movie. I get the following eror:
the quicktime4linux lib really doesn't handle most quicktime codecs. 'rpza' or road pizza is the code for cinepak codec originally used by quicktime. it's now mostly deprecated in favor of faster higher quality codecs.
i'm not sure why you would want to use mpeg2 with GEM as it's a really not a good choice for real-time use. interframe compression kills frame rates, and try playing any mpeg backwards sometime. on the other hand it's great for low bandwidth delivery. there is a quicktime6 plugin that does mpeg2 conversion if you really want to go that way.
here are some good codecs for real-time video: photo-jpeg - low bandwidth and low cpu usage animation - if you are using RGB for processing then animation saves yuv->rgb conversion DV - actually works quite well on faster machines
ok codecs: motion-jpeg - large files and slow to decompress. there are some cards that do hardware mjpeg uncompressed - if you have the bandwidth (up to 36MB/sec) you can get decent performance
not so good: mpeg1,2,4 sorenson 1,3 anything with keyframes
unfortunately you don't have a very good selection to choose from on linux. i tried to get decent performance from quicktime4linux and was always fairly disappointed with the results.

It might be a misconfiguration as I found out that rpza is the standard Apple Quicktime codec and Gem's docs say this format is supported. If I can't get this to work: Does anybody know of any way to convert a quicktime Movie to Mpeg2 on a Linux machine or a Mac?
