[linux-dvb] Re: burning SVCD
Hello all,
I viewed a recorded stream on my DVD Player! Here is my complete success
story and every used version:
I checked out the DVB module yesterday and tried your remux program with
a stream (from SuperRTL) generated already before by the latest driver
package (siemens_dvb-0.8.tar.gz plus gVideo/record) but this should not
make a big difference to the newest of the CVS module... I have a
Hauppauge DVB-s.
I used streamcutter0.92 (java2/v1.3) to get a clean start and end of the
stream.
Next I used remux (head of output below):
wolfi@wolfis:/home/wolfi > DVB/apps/mpegtools/remux
Ppanter.pva_cut_33.41 2324 2 > Ppanter.pva_remux
Reading Ppanter.pva_cut_33.41
Package size: 2324
Videostream: ASPECT: 4:3 Size = 480x576 FRate: 25 fps BRate: 15.00
Mbit/s
Audiostream: Layer: 2 BRate: 192 kb/s Freq: 48.0 kHz
Video start PTS = 4949.240822s
Audio start PTS = 4948.527389s
Difference Video - Audio =
0.713433s
The result was approx. 770MB in size.
To use vcdimager-0.5.9alpha1 I patched libvcd/vcd.c at line 364:
if (end < 0)
end = begin+(23*60)+16;
/*end = vcd_mpeg_get_timecode (buf);*/
So the endtime was fixed to begin plus 23min 16sec, otherwise vcdimage
always told me that the end was before begin. This is a brute-force
hack, just because I wanted to continue....
I started vcdimager:
vcdimager -t svcd Ppanter.pva_remux
Now I had a image (820MB in size) which I burned with cdrdao 1.1.4 and a
TEAC CD-R56S on a 80min CD with a little bit overburning....
My first tries on the PC failed (e.g. WinDVD) - then I just put it just
in my DVD Player (Cyberhome AD-N212).
The player wrote 'PBC ON CHAOJI VCD' and played it - with good A/V
sync and quality!
Some small problem - the time counter on the player was completely wrong
... it seems that vcdimage just used the timeinfo of the original
stream... Maybe a feature in the remux to overwrite the time information
starting at 0:00 would be very useful. But for this I have too less
knowledge of MPEG2.
Thanks for this great tool!
Next I try channels using 720x576 or other resolutions with my player...
Bye,
Wolfgang
