What are the available codecs for recording with jit.qt.vcr?

i want my client to be able to choose which codec he wants to record video (using umenu and sprintf). Last year i had a problem that h264 is not available but it was listed in the helpwindow. To avoid including unsupported codecs I would like to know what codecs are supported.

a ‘getcodeclist’ message to jit.vcr should dump out a complete list of all valid codecs with a functioning compressor component.

The list shows h264 while cycling says it is not supported at the moment. So I cannot use this list. Isn’t there a list on the site?

My apologies, indeed h264 is not supported, as the API we use doesn’t support multipass compression, frame reordered codecs, etc. Here is a little more info on the topic:

Down the road we will be updating to a newer API.

What I would suggest regardless is coming up with a list of codecs that are actually useful and filling a umenu with those. IMO using h264 in realtime is not one of them.

Sorry for the inconvenience in the meantime,

The project I am doing, I will send to somebody who does not have MaxMSP and lives far away. The only way to change the video settings will thus be with umenus. He needs to experiment what codec is going to give the best results. I do not have sufficient knowledge to say which codec to use, so I want him to decide (what seems good to me, may seem bad to him). So I ned to have a list that I can put in the umenu with the available codecs.
