As mr Pullan said! - for whoever is interested (apart from me I mean :) ) there are now patches to the driver available agaimst 2.6.14, courtesy of Peter Beutner, that clear up all of the anomalous dec behaviour. Peter is submitting these so they should eventually end up in the standard driver. Wrt to myth the dec still needs a section reader as the driver doesn't support PES_OTHER filtering - though the test can now be simpler as a request to set a PES_OTHER filter now fails. Obviously I don't know if any of the other USB drivers will support a simpler test. Basically with these driver patches the dec works quite happily with the current svn (ca 7897 to at least 8154) - for recording, livetv and scanning(using tuned full scans, simple full scan's seem to change the dec too frequently and it eventually gets upset) The main patch is available at: http://www.linuxtv.org/pipermail/linux-dvb/2005-July/003237.html The following patch, (also from Peter), additional to the above is needed to ensure failure of PES_OTHER filtering is reported consistently to myth and hence that the section tracker gets invoked. --- linux/drivers/media/dvb/ttusb-dec/ttusb_dec.c.orig +++ linux/drivers/media/dvb/ttusb-dec/ttusb_dec.c @@ -965,8 +965,8 @@ static int ttusb_dec_start_ts_feed(struc case DMX_TS_PES_TELETEXT: dec->pid[DMX_PES_TELETEXT] = dvbdmxfeed->pid; - dprintk(" pes_type: DMX_TS_PES_TELETEXT\n"); - break; + dprintk(" pes_type: DMX_TS_PES_TELETEXT(not supported)\n"); + return -ENOSYS; case DMX_TS_PES_PCR: dprintk(" pes_type: DMX_TS_PES_PCR\n"); @@ -975,8 +975,8 @@ static int ttusb_dec_start_ts_feed(struc break; case DMX_TS_PES_OTHER: - dprintk(" pes_type: DMX_TS_PES_OTHER\n"); - break; + dprintk(" pes_type: DMX_TS_PES_OTHER(not supported)\n"); + return -ENOSYS; default: dprintk(" pes_type: unknown (%d)\n", dvbdmxfeed->pes_type); Finally - if you want to use eit guide data with the dec then the mask and filter values need to be set in the eit pid setup - as follows - (this is a myth change but this time I think the dec is just about behaving as it should - the mask in the patch picks up all eit sections - you may want to cut out the 4E/4F current-next tables by changing the filter and mask eg to + Table[EVENTS]->AddPid(0x12,0x7D,0x82,true); Index: mythtv/libs/libmythtv/siparser.cpp =================================================================== --- mythtv/libs/libmythtv/siparser.cpp (revision 8142) +++ mythtv/libs/libmythtv/siparser.cpp (working copy) @@ -1293,7 +1294,7 @@ // TODO: This is temp Table[EVENTS]->DependencyMet(SERVICES); - Table[EVENTS]->AddPid(0x12,0x00,0x00,true); + Table[EVENTS]->AddPid(0x12,0x7F,0x80,true); } /** \fn GetLanguagePriority(const QString&) _______________________________________________ mythtv-dev mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-dev
