V4L2 multistream support

V4L2 multistream support

Postby crazycat » Sat Oct 29, 2011 2:43 am

I add multistream support for latest linux TBS V4L sources - http://crazycat69.narod.ru/sattelite/li ... upport.zip.

modified dvbsnoop - https://bitbucket.org/CrazyCat/dvbsnoop
modified scan-s2 - https://bitbucket.org/CrazyCat/scan-s2
modified szap-s2 - http://crazycat69.narod.ru/sattelite/linux/szap-s2.tar.bz2

* core patch - new demod property DTV_DVBS2_MIS_ID (alias for DTV_DVBT2_PLP_ID).
* stv090x demod driver patch - setup MIS filtering from DTV_DVBS2_MIS_ID
* modified scan-s2, szap-s2 utils:
- added -m switch for MIS selection
- additional field in transponder info files for MIS (used by scan-s2)
- additional flag Pnum in VDR channel info (generated by scan-s2 and used by szap-s2)

Multistream supported for all STV0903BAC, STV0900BAC, STV0900AAB/AAC devices, which use stv090x demod driver. In current V4L-sources this is TBS6925, 6992, TBS5980 and another devices like Techisat SkyStar HD USB, Omicom S2 PCI (with my patch to budget.c, included)

So - unpack my archive to dir with linux-tbs-drivers, run patch.sh. Next build as described in README from linux-tbs-drivers.

P.S. Some transponder info for scan-s2 with well-known multistreams on 31.5E:
Code: Select All Code
S2 11914000 H 27500000 AUTO AUTO 8PSK 2
S2 11914000 H 27500000 AUTO AUTO 8PSK 3
