Looks like you need to get avifile. It's on SourceForge. I grab it from CVS rather than using snapshots. > Is anyone interested in trying to put together a 'distribution' > of an integrated set of these things for newbies? Well, kinda. I have been thinking of starting an OpenPVR[1] project on SourceForge if nothing else, just to get the (seems like) hundreds of people all doing this together and sharing their ideas. I have brought together a bunch of stuff for downloading television programming so that scheduling can be done by program title rather than by date/time. I also wrote a scheduler that takes all of the programs you want to record from the downloaded programming and tries to schedule it all so that you record as much as possible. It does not scale well right now I'm afraid due to it's is a brute-force search methodology for the schedule that allows for the most recording. It needs a com-sci hacker to attack the algorithm looking for decompositions, etc. > Maybe a best > of breed player for TV/DVD/MPEG/NET plus a capture utility/net > server and a streamer, so that people can download a single file, > make, make install, and have working video? Well the problem is that best-of-breed is a moving target based on what hardware you have available, what quality you demand from your recordings, etc. Some people have lots of CPU so they can save on diskspace by using CPU intensive encoders. Some peple demand higher resolutions and better quality than others. I am fairly happy with 320x240 at about 1800kbps but I am just casually watching and I don't have the processor for a lot more (only an Athlon 800). I am sure there are lots of people here for whom that is just unacceptable. I have started working on a single wrapper for the various encoders that basically takes a single set of recording parameters (chock full of defaults) and an encoder to use and it converts the single set of parameters to the native parameters for that encoder. Right now it supports DIVXrec and mp1e. The command switches are only what I have needed to cover so far. It does right now support "end capture time" specification (assumes start time is "now" for now) which is a "natural date" type of specification (i.e. --end 3:30pm) and calculates the number of frames needed to capture for the encoders that want a frame count rather than a time specification. No more having to figure out "x fps * y num_secs * z num * minutes == n frames to capture". > I'm a professional > programmer, and I have a hard time, I suspect that my mother > won't be doing any video under linux for a long time. <G> No, not likely. :-) 1. Maybe LinuxPVR is more appropriate as most of this stuff is tied to Linux in terms of being tied to V4L[2] -- maybe if there is enough interest some non-linux porting will happen and then OpenPVR would be more appropriate again b. -- Brian J.
