Hello all!Hmmm. Haven't seen this one before I don't think. If this file was not multiplexed for SVCD it probably has to be re-multiplexed at a minimum so that the pack size is 2324. I'd have to look at the code but the vcdimager may assume (rightfully so) that it can just read in 2324-byte blocks at a time and each will be one pack. The pack header is the 32-bit value 0x000001BA and is at the beginning of each pack.
Im new to this list and video processing in general so please excuse me if my questions seem stupid, thanks.
I have a mpeg-file and want to create a svcd-image with vcdimager, but it tells me the following:
<[EMAIL PROTECTED] ~>vcdimager -t svcd -l 'Good Bye Lenin CD1' -v -p input.mpg --DEBUG: initializing libvcd 0.6.2 [linux-gnu/i686]
INFO: scanning mpeg track #0 for scanpoints...
**ERROR: mpeg scan: pack header code expected, but 0x00000000 found (buflen = 2324)
The SVCD spec limits the overall data rate of the program stream to <=150 sectors per second ==> 2324 * 150 = 2907600 bits/sec. According to the above info you're a little over that but if that's the peak rate than you man be ok. Note that the rate I've mentioned is for the program stream as a whole so you'll have some overhead above the separate video and audio rates.According to the information mplayer prints on stdout, the format of the file seems to be suitable for a SVCD:
VIDEO: MPEG2 480x576 (aspect 2) 25.00 fps 2875.0 kbps (359.4 kbyte/s) AUDIO: 44100 Hz, 2 ch, 16 bit (0x10), ratio: 28000->176400 (224.0 kbit)
So I googled for information on MPEG, (S)VCD and Linux and ended up here at mjpegtools, which seems to be the right tool for the task of SVCD-creation. I will try to reencode the file with mpeg2enc but I wanted to ask some experts first if this is really necessary because I think the deconding/encoding procedure will reduce the quality of the video, won't it?
It sounds like maybe all you need is a re-multiplexing of the files.
