dv file from minidv camera - interlaced. small dv created by imported jpeg images - not interlaced. seems that when I use ffmpeg2theora with deinterlace switch and reduce size, it works. But when the only reduction I am doing is to width (720x480 -> 640x480) the encoder ignores the naturally interlaced bit and uses the last de-i...

...g to reverse engineer hardware and produce something useful and featureful. I wish to make a change to the nouveau source. You might say I am considering becoming a nouveau developer. I am one of those crazy nutters who connects my nvidia card directly to a television via a vga2scart cable using interlaced video modes. As you are probably aware, interlaced video signals generate two alternating half frames or 'fields', which the interlaced display cleverly weaves together to form a full picture. DVD playing software typically works by generating a progressive video stream by combining two...

Right now, we make the mistake of allowing interlacing on all connectors. Nvidia hardware does not always support interlacing with DP though, so we need to make sure that we don't allow interlaced modes to be set in such situations as otherwise we'll end up accidentally hanging the display HW. This fixes some hangs with Turing, which would be caused by attempting to set an interlaced mode on hardware that doesn't support it. This patch likely fixes other hardware hanging in the sam...

We advertise being able to set interlaced modes, so let's actually make sure to do that. Otherwise, we'll end up hanging the display engine due to trying to set a mode with timings adjusted for interlacing without telling the hardware it's actually an interlaced mode.

I want to interlace two vectors. This I can do: > x <- 1:4 > z <- x+0.5 > as.vector(t(cbind(x,z))) [1] 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 but this seems rather inelegant. Any suggestions? Murray -- Dr Murray Jorgensen http://www.stats.waikato.ac.nz/Staff/maj.html Department of Statistics, Univ...

Can anyone tell me if it is possible to encode music in an "interlaced" format.. perhaps I should explain what I mean by this. Say I'm getting 1k/sec off some guy's modem on opennap. It would be sweet if I could listen to the song as it is downloading but obviously the quality is gunna suck. So suppose the song was encoded in this interlaced fashion,...

Currently, nouveau doesn't actually bother to try probing whether or not it can actually handle interlaced modes over DisplayPort. As a result, on volta and later we'll end up trying to set an interlaced mode even when it's not supported and cause the front end for the display engine to hang. So, let's teach nouveau to reject interlaced modes on hardware that can't actually handle it....

as per yesterday's discussion at #theora -- It has been suggested that we devise a method such that we will be able to add certain features to the bitstream (interlace, exotic color subsampling, clip length flag for download, etc), in such a way as to not obsolete streams encoded previously. Rillian's suggestion, which is pretty much standard practice, is to add a bitstream revision number. Another suggestion was to move to a tag structure, where parameters...
