Linux Movies Group Meeting

Recap of meeting #4, Wednesday, May 1, 2002, 7pm
by Robin (rower@movieeditor.com)

Thanks to everyone who came and helped make the meeting a success! Headcount was 12: Robin,Gabrielle, Greg, Michael, Jason, Ramona, Drew, Kelsi, Dado, Stuart, Jim, Beth. As usual these are just highlights of my recollection of conversations -- not complete or necessarily accurate. This recap is more fuzzy than usual because I was too busy to write up my notes right away, and can hardly make them out now.

Jason and Ramona talked about Linux at NAB. They are working on a Linux driver for the AJA HD 10-bit YUV (only) card and demonstrated their editing technology in their booth. Piranha has a Linux port. Discreet Combustion 2 had a Linux demo at NAB.

Stuart the acting chair for the San Francisco SIGGRAPH mentioned their meetings.

Greg and Michael talked about Shake.

Robin talked about how his company had been founded to develop software for P2P video editing, but ended up writing codecs instead.

Drew talked about a plug-in for RAYZ he is working on using DV2 format in libdv. Drew mentioned something about Ming, which seems to be a Flash C library. He and Jason talked about a new HD camera from Thompon being designed to output a Cineon-like log format.

Michael talked about RAID and striping across NFS. He mentioned that Rythym and Hues (Film Gimp) worked on Spider-man. I later confirmed that it was the Spider-man commercials (such as the popular spot by Cingular), and not the movie itself that R&H worked on.

Beth said she liked that Python is portable across Linux, Mac, Irix, and NT; and that you don't have to compile it. Jim mentioned that you can share byte-compiled Python code (sort of like Java), that ytou don't have to provide source code. Dado talked about space/tab confusion caused by the feature of Python that indentation is syntax. Python uses whitespace rather than braces like Java or C. Drew said he likes that he can use Python as a command-line calculator. Jerry said how much he likes GetAddr() in Python.

From the Python library reference:

getaddr (name) -- function of module rfc822

Return a pair (full name, email address) parsed from the string returned by getheader(name). If no header matching name exists, return None, None; otherwise both the full name and the address are (possibly empty )strings.

 

Example: If m's first From header contains the string* 'jack@cwi.nl (Jack Jansen)', then m.getaddr('From') will yield the pair ('Jack Jansen', 'jack@cwi.nl'). If the header contained 'Jack Jansen <jack@cwi.nl>' instead, it would yield the exact same result.
