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-interlaced frame. Since the small bit made from jpegs is a dv

Taking a look ahead at your QT (OSX version) work, you have Theora Encoding and Decoding on the list. This could be very beneficial as many times the only way to get a constant frame-rate out of QT is to export (and for DV video recorded in QT, this can be a large issue). Another major issue is that the video coming from DV (at least the sources I have used) is almost always

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, I would be able to

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 ran into this issue on a gm204 GPU with a display reporting interlaced modes. Nvidia dropped those modelines for DP, but not HDMI. We should do the same on hardware where interlaced modes aren't supported via DP.

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.

Hi, Intel has recently open sourced otion compensation code (XvMC) for their i915/i945 integrated graphics chips. See: http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=blob;hb=xvmc-i915;f=src/xvmc/I915XvMC.c XvMC API was intended for MPEG{2,4} class of codecs - so it can not be used for Theora as-is. However, could at least some parts of it such as hardware accelerated

Mesa only supports the non-spatial temporal deinterlace (deint=3). I'm guessing that due to some unfortunate issues, you're no longer getting hw accelerated video decoding. Check in vdpauinfo to make sure that it's indeed showing the relevant codec as supported. If not, you can turn that back on by updating to mesa 11.2.2, or downgrading your kernel to 4.2 or earlier.

I like the posibiliti to add a metode for compress interlaced video in theora, and I think three metodes and are this: 1. compres the filed at separates frane streams, is the worst metode. 2. assort the first field of the frame to display in the top of the frane and the other in the boton for obtain one frame and make a frame whithot problem to compress whith all of the interlazed data but this

Adds H.264 and MPEG2 codec support via VP2, using firmware from the blob. Acceleration is supported at the bitstream level for H.264 and IDCT level for MPEG2. Known issues: - H.264 interlaced doesn't render properly - H.264 shows very occasional artifacts on a small fraction of videos - MPEG2 + VDPAU shows frequent but small artifacts, which aren't there when using XvMC on the same
