The mercury repository is on linuxtv, so presumably one of you can do it :-). It is wierd that (1) those numbers are swapped between fc17's vs upstream, (2) the numbers also change between runs.... > > - 'scandvb' segfault at the end on its own. > > I didn't see that. This is fc17's - it does so in a string function (v*printf) - probably easy to fix if/when I get the debuginfo package, if it isn't fixed upstream already. > > - "scandvb /usr/share/dvb/dvb-t/uk-SandyHeath" > (supposedly where I am) got a few "WARNING: >>> > tuning failed!!!" and no list. This is where it gets confusing - /usr/share/dvb/dvb-t/* and /usr/share/doc/dvb-apps-1.1.2/channels-conf/dvb-t/* have similiar names, but different content, and no explanation which is which. The latter seems to be in the correct format you wrote below, but does not work. One thing would be nice to do would be write up a description of those formats, and say which is which. > > - 'w_scan -G -c GB' > > have a few curious > > WARNING: received garbage data: crc = 0xcc93876c; > expected crc = 0xb81bb6c4 > > > > return a list of 26, with entries like (which seems to > be vaguely correct): > > > > BBC > ONE;(null):522000:B8C23D0G32M64T8Y0:T:27500:101=2:102,106=eng:0:0:4173:9018:4173:0:100 w_scan is the only one which seems to be able to scan, but its output format isn't correct.

I just found a dvbv5-scan on my harddisk (fc17) also, and dvbscan is in locate.db but gone. Apparently one might be 'scan' but too confusing and got its name changed during packaging. > > So I just put it in ~/.mplayer:channels.conf > > > > Took me a while to figure out that mplayer wants: > > > > mplayer 'dvb://BBC ONE;(null)' > > > > rather than anything else - curious about the ';(null)' > part. > > > > -------- > > Playing dvb://BBC ONE;(null). > > dvb_tune Freq: 522000 > > ERROR IN SETTING DMX_FILTER 9018 for fd 4: ERRNO: > 22ERROR, COULDN'T SET CHANNEL 8: Failed to open > dvb://BBC ONE;(null). > > ---------- > > Typical channels.conf entry looks like that: > MTV3:714000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_AUTO:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:305:561:49 > > And tuning to that channel using mplayer: > mplayer dvb://MTV3 Well that at least clear up something - I tried this form (from /usr/share/doc/dvb-apps-1.1.2/channels-conf/dvb-t/* ) but did not get anything either - the error message seemed worse so I didn't go further. I guess I should try getting w_scan to do this form. > However, I prefer VLC. Just open channels.conf to VLC and > should show playlist.

There seems to be at least two channels.conf formats (one for mplayer/vlc/gstreamer, one for vdr?), and unfortunately both seems to have the same name conventionally, but different content. I can't find documentation about either, or even examples :-). I am also surprised by the checksum failed message with w_scan, and that it does not change output format with adding options, etc. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
