If you'll take a look at the table 7.4 in ANSI/SCTE 57, you'll see that the stream type 0x80 is DigiCipher2 video and 0x81 is used for AC-3: http://www.scte.org/documents/pdf/standards/ANSISCTE572003DVS507.pdf IMO, the current "channel->IsAtsc()" check in pat.c should be replaced with a stream identification via the registration descriptor. Then it's back to working out why my pvr-hd ac-3 (h264 and ac3 @ 720p) don't work in vdr-xine and xbmc/vnsi.. (although do work in vdr-xineliboutput and xbmc/streamdev..) I guess XBMC/VNSI is using their own PMT parser, so you'll have to add these same hacks into them. BR, -- rofa ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
[vdr] New ATSC Video Type 0x80?
I am trying to get my head around ATSC / AC3 and have discovered some ATSC Clear Qam channels disappear when update channels is on. Some playing around with pat.c and the isyslog command, I have discovered they appear to have a different type than normal.. Normally Mpeg2 is type 2, but these are 0x80? I notice they do the same thing with AC-3 (0x81 instead of 6) so probably something similar is going on. Sep 2 23:11:29 oac vdr: [5815] pat.c stream type = 80, pid = 2240 Sep 2 23:11:29 oac vdr: [5815] pat.c stream type = 81, pid = 2241 Sep 2 23:11:29 oac vdr: [5815] pat.c wants to update channel Sep 2 23:11:29 oac vdr: [5815] changing pids of channel 355 from 0+0=0:0;22...@106:0:0 to 2240+2240=128:0;22...@106:0:0 If hard coded with vpid and pid of 2240=2 and update channels of, then the picture shows.
