[Mjpeg-users] generate a DVD? prepare data for dvdauthor?
Hi, i try to burn a DVD made with some material that i've cut and edited. Nearly every page i've found describes how to get the data _from_ a DVD, not how to generate it _for_ a DVD. Also in the MJPEG-Howto there is only described how to create a VCD or SVCD, not for DVD. I'd like to prepare an MPG (Video and Audio) so i can use this file as an input for dvdauthor. From the man-page and some examples in the internet i already found out that i need to mplex the data with: mplex -f 8 -o final.mpg video.m2v audio.mp2 But how can i create video.m2v and audio.mp2 with either transcode or mencoder?

[Mjpeg-users] creating a YUV stream from PNGs, distorted output with garbage
Hi everybody,
i try to generate an MPEG that is suitable for a background menu for a DVD.
So i used a Perl script to generate some pictures:
#! /usr/bin/perl -w
use GD;
my $n = 25;
for(my $i = 0; $i $n; $i++) {
my $img = GD::Image-new(720, 576);
my $white = $img-colorAllocate(255, 255, 255);
my $black = $img-colorAllocate(0, 0, 0);
# $img-transparent($white);
$img-rectangle(10, 10, 10+2*$i, 10+3*$i, $black);
save_png(sprintf(pic/img%02i.png, $i), $img);
}
sub save_png {
my ($fname, $im) = @_;
local *FH;
open FH, $fname or die can't write-open '$fname'\n;
binmode FH;
print FH $im-png();
close FH;
}
Then i used mogrify * on all the images. before that i got
some complaints from png2yuv:
png2yuv -v 2 -f 25.00 -I t -L 1 -n 24 -j pic/img%02d.png menu.yuv
INFO: [png2yuv] Parsing checking input files.
--DEBUG: [png2yuv] Analyzing pic/img00.png to get the right pic params
INFO: [png2yuv] Image dimensions are 720x576
INFO: [png2yuv] Movie frame rate is: 25.00 frames/second
INFO: [png2yuv] Interlaced frames, top field first.
INFO: [png2yuv] Frame size: 720 x 576
INFO: [png2yuv] Now generating YUV4MPEG stream.
**ERROR: [png2yuv] mpegz: UNKNOWN COLOR FORMAT 3 in PNG transformation !
So after mogrifying the pictures i can create a YUV stream.
png2yuv -v 2 -f 25.00 -I t -L 1 -n 24 -j pic/img%02d.png menu.yuv
... lots of debug stuff ...
But when i use MPlayer to show the stream i get lots of garbage output.
In the output i can see the generated pictures, but they are heavily
distorted and garbage is added.
Can anybody tell me what is going wrong?
Do i use incorrect parameters?
Best regards,
Torsten.

Re: [Mjpeg-users] Driver installation?
Hi, thanks for the hint. But it looks like my card is damaged. As i think about replacing it now i thought i'd first ask here for recommendations. What card should i buy for digital video editing under Linux? i got the hint by private mail to clean the contacts of the PCI card. That actually worked, now the card is recognised and modprobing saa7110, adv7175 and zr36067 gives correct entries in /var/log/messages. (First capturing failed, but that may be a problem of the cables). Best regards, Torsten. --- SF.Net email is sponsored by: Tame your development challenges with Apache's Geronimo App Server.

Re: [Mjpeg-users] Driver installation?
Hi, Your card appears somewhat broken, the correct id is 0x7efe, not 0x7e7e (note how the highest bit of the last byte is missing). Try modprobe zr36067 card=2 to workaround failing autodetection; it may work, but it may just bail out randomly elsewhere if the card really is damaged. thanks for the hint.

[Mjpeg-users] how to encode an MPEG from an AVI?
Hi, i did not encode any MPEGs from an AVI for a longer time. I used to use mp2enc for that, but it seems it is not in the latest distribution i use any more.

[Mjpeg-users] Error initializing Audio: Audio task died.
Hi, thanks for the hints to get the mjpeg tools to compile, now it works. I still have the problem that glav dies immediately because it can't open ALSA audio on my 2.6.7 with onboard sound-intel8x0. I took a look int audiolib.c to see what the problem could be. The message i get is: **ERROR: [lavplay] Error initializing Audio: Audio task died. \ Reason: Error mapping audio buffer - Input/output error I think this is related to line 805 in audiolib.c if (audio_capt) buf=mmap(NULL, tmp, PROT_READ , MAP_SHARED, fd, 0); else buf=mmap(NULL, tmp, PROT_WRITE, MAP_SHARED, fd, 0); if (buf==MAP_FAILED) 806: system_error(mapping audio buffer,fd, 1); So maybe this is rather a problem of my shared memory subsystem in the kernel?

Re: [Mjpeg-users] Build VDR, Tuner needed
Hi, thanks for that hint. Yes, i'm in Germany. I also had the idea to use my Sony VCR as a tuner and control it via its S-input (not S-Video but S-Control) to change to a certain channel.

[Mjpeg-users] Announce: some effect tools
Hi, i just wrote some tools that use liblav to do some effects on AVI video streams that are captured with lavrec. Thay are available at: http://www.s.netic.de/tmohr/lavfilter.tar.bz2 The name is kind of misleading. The tools can do: - pngblend: blend two streams into a final one. - pngoverlay: overlay some PNG pictures over a video stream - pngtrans: do some transitions between several AVI streams I'd be glad to hear any comments on those tools. Best regards, Torsten. Here's an example on how to start them: #! /bin/bash # These tools are slow, because the convert the AVI streams to RGB # values. This takes some time... # This one takes a stream from left side -l file and a stream from # right side -r file outputs it to -o file. the left side of the # output stream (0 to -n xvalue) comes from the left stream, the # right side (-m xvalue to maximum width) comes from the right stream. # All values between -n x1 to -m x2 are mixed. # No sound at the moment. # ./pngblend -l ../lav_examples/file1.avi -r ../lav_examples/file2.avi \ # -n 354 -m 414 -o qq.avi # This one works like the example above, except that a -p picture.png # is used to decide from where a value comes (black:left - white:right). # Inbetween values are interpolated. # No sound at the moment. # ./pngblend -l ../lav_examples/file1.avi -r ../lav_examples/file2.avi \ # -o qq.avi -p ../lav_examples/bfile.png # These examples take an input stream and overlay a PNG file that comes # from -p mask. An offset (-a) can be set to a offset (where the # overlay starts). # Sound is just copied to the output stream. # ./pngoverlay -p ../lav_examples/in/%04d.png -b 1 -e 15 \ # -i ../lav_examples/in.avi -o out.avi -a 1 #./pngoverlay -p ../lav_examples/in/%04d.png -b 1 -e 15 \ # -i /vid/volltreffer1.avi -o out.avi -a 1 #./pngoverlay -p ../lav_examples/in/%04d.png -b 1 -e 15 \ # -i ../lav_examples/peanuts.avi -o out.avi -a 1 # This one puts the output into -o res.avi. # The order of the command line parameters matters. # There are parameters that describe an input stream: # -f input file name # -b begin frame number # -e end frame number (negative values are counted from the end) # # There are parameters that describe a transition from one stream to # another (or to/from video:black / sound:quiet): # -v number: video transition lasts number frames # -s number: sound transition lasts number frames # -a number: video offset # -b number: sound offset # # Example: file1 has frames 1 to 50, file2 has frames 1 to 70. If the # video transition between those two is 15, the resulting video sequence # is like this: # frames 1 to 34 from file1 # frames 35 to 50 are mixed with frames 1 to 15 from file2 # frames 51 to 105 from file2 # # If a video offset is given, e.g. 7 it all looks like this: # frames 1 to 41 from file1 # frames 42 to 57 are mixed with frames 1 to 15 from file2 # frames 58 to 105 from file2 #./pngtrans -o res.avi \ #-v 50 -s 50 \ #-f ../lav_examples/peanuts.avi -b 13 -e 150 \ #-a 50 -v 20 -s 20 \ #-f ../lav_examples/cc1.avi -b 26 -e 150 \ #-v 50 -s 50 --- This SF.net email is sponsored by: Scholarships for Techies!

[Mjpeg-users] lav_read_audio: how many samples for ONE frame?
Hi, i try to do some video and audio effects on some AVI streams, i have some questions related to that, it would be great if someone could give me some hints. I just sampled an AVI stream with lavrec, audio in 16 bits, 1 channel, audio rate is 11025. When i open that stream and read out the informations in it i get: Video frames: 438 Video rate: 25.0 frames per second Audio channels: 1 Audio Bits: 16 Audio Rate: 11025 Audio Samples: 192413 I try to check the audio sample number now: 438*11025/25 is 193158, that's higher than the number in the stream. 437*11025/25 is 192717, that's still too high, though i took one frame less. I'd like to mix two (or more) streams (video works!) but when i try to figure out how many samples are related to a video frame it gets annoying. I only work with frames with matching audio/video parameters, so rate, bits, channels are the same. As in the example above, it seems i can't just try to read the (audio_rate/video_rate) samples. So i tried it a different way: audio_pos = video_frame * audio_samples / all_video_frames; audio_pos = ~1; I calculate the size of the data as: size = audio_pos(frame+1) - audio_pos(frame); But this leads to differing sizes, sometimes 438, sometimes 440. (Also, for large number of frames there can be an overflow.) So when i read in video frames from TWO streams, the audio size of the first one may be 438, the second one 440. This leads to complicated algorithms for mixing the audio data. Has anybody got an idea of how to read in the audio chunks related to a frame? I'd like to use a fixed buffer size, this would make things much easier.

[Mjpeg-users] reading an AVI file, how to get the sound?
Hi, in /usr/include/mjpegtools/lav_io.h there are several functions declared to access/read/write a file recorded with lavrec. I have used these functions to read/write lavrec files. But how do i access the samples that are related to a picture? As i understand it, there is video information and sound information mixed in the file. I can read every frame i'd like with e.g. lav_read_frame. I assume it can be seen like this: PIC1...PIC2...PIC3...PIC3 soundsoundsoundsoundsoundsoundsoundsoundsound How can i read the samples that are related to this frame? To read out the audio info, do i do it like this? - read the audio information (bits, channels, rate, number of samples) - read a video frame N - set audio position N (lav_set_audio_position) - read that audio sample (lav_read_audio) If i do it like this, is video frame N in sync to the audio data then?
