[Mjpeg-users] perl bindings for LAV-Tools and SDL
Hi, i just uploaded the C++ wrapper and the perl bindings for lavtools: http://www.s.netic.de/tmohr/lavperl-0.3.0.tar.bz2 This one: - fixes a bug that prevented the previous version from working. - contains a pach for SDL_perl-1.20.0 that adds the a functionality to return a Surfaces data as a perl string. - contains an example perl code that loads an AVI, lets one single step through the frames, shows each frame in an SDL window and writes each frame into an output stream. It is also possible to write an animation directly from SDL Surfaces. Best regards, Torsten. --- This SF.net email is sponsored by: SF.net Giveback Program.

Re: [Mjpeg-users] YUV Image type
> Starting to dig a little bit deeper than the passive use of mjpegtools, I'd > like to know what kind of image is a YUV image once piped ? > Does it fit into scalar, color or vector type of images (or none of them). The "yuv4mpeg" format is a binary stream that starts with a text formated header describing the content (image size, aspect ratio, frame rate and interlacing information). The header is followed by frames, which all begin by "FRAME\n" followed by the frame data. The frame data are raw pixels in YUV planar format. Each pixel is described by 3 independant values: Y (luminance), U (blue chrominance) and V (red chrominance). Those values are split in 3 independant planes (you can think of a plane as an image carrying only part of the pixel - one plane for Y, one plane for U and one plane for V). The U and V planes are downsized by a factor 2 in each direction, and the 3 planes are output one after the other in the byte stream. For a 320x240 image, you get Y(0,0) Y(0,1) ... Y(0,319) Y(1,0) ... Y(239,319) U(0,0) U(0,2) ... U(0,318) U(2,0) ... U(238,318) V(0,0) V(0,2) ... V(238,318) This is called YUV4:2:0 planar format. For more information about the different YUV formats, have a look at http://www.fourcc.org. Laurent Pinchart --- This SF.net email is sponsored by: SF.net Giveback Program.

Ugh... no, it's not so simple. Some clarifications: 1) For the sake of precision, the colorspace is "Y'CbCr", not "YUV". 2) The chroma channels are not at the same resolution as the luma channel (4:2:0 subsampling) and to make them the same resolution requires upsampling. The yuv4mpeg(5) manpage describes the YUV4MPEG2 stream format. See http://www.mir.com/DMG/ for additional information on colorspaces and subsampling standards, and links to even more information on the same. -matt m. --- This SF.net email is sponsored by: SF.net Giveback Program.

[Mjpeg-users] mplex -O
Can someone explain to me how's mplex -O supposed to work?
I'm using the current (sunday nov 23, in the evening) mjpegtools CVS
tree.
I'm doing this:
mplex -f 8 -S 150 -O 500 ${proj}.m2v ${proj}.ac3 -o 1.vob
mplex -f 8 -S 150 -O -500 ${proj}.m2v ${proj}.ac3 -o 2.vob
Then i compare the sync info on the two VOBs like this:
[EMAIL PROTECTED] stnem]$ tcprobe -H 100 -i 1.vob
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for 1.vob, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 16:9 (*)
frame rate: -f 23.976 [25.000] frc=1 (*)
PTS=0.2008, frame_time=41 ms, bitrate=9800 kbps
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x2000
[0x2000]
PTS=0.1780, bitrate=448 kbps
-D 0 --av_fine_ms 22 (frames & ms) [0] [0]
[EMAIL PROTECTED] stnem]$ tcprobe -H 100 -i 2.vob
[tcprobe] MPEG program stream (PS)
[tcprobe] summary for 2.vob, (*) = not default, 0 = not detected
import frame size: -g 720x480 [720x576] (*)
aspect ratio: 16:9 (*)
frame rate: -f 23.976 [25.000] frc=1 (*)
PTS=0.1780, frame_time=41 ms, bitrate=9800 kbps
audio track: -a 0 [0] -e 48000,16,2 [48000,16,2] -n 0x2000
[0x2000]
PTS=0.2008, bitrate=448 kbps
-D 0 --av_fine_ms -22 (frames & ms) [0] [0]
As you can see, the PTS A/V differences on the two VOBs, while
symmetrical, are a lot smaller than the projected 500 ms difference that
i was trying to enforce with mplex -O.
tcprobe suggests a +/- 22 ms difference (-D 0 --av_fine_ms 22) between
audio and video.
Just in case tcprobe does not report correctly, i verified the two VOBs
with xine, and the A/V sync is more like what tcprobe said (the A/V sync
difference is so small it cannot be detected) than what mplex was
supposed to do (half a second difference, which is very big and easily
detectable).

[Mjpeg-users] Problems loading zoran-driver for Pinnacle DC10+
