Channelscanner misses some transponder
| Reported by: | buehlmann@… | Owned by: | stuarta |
|---|---|---|---|
| Priority: | minor | Milestone: | 0.25 |
| Component: | MythTV - Channel Scanner | Version: | head |
| Severity: | medium | Keywords: | |
| Cc: | Ticket locked: | yes |
Description
I'm using the 0.22-fixes branche in a dvb-c system.
If I do a tuned full-scan, the scanner misses all channels of some transponders. If I explicity scan one of the missed transponders, all channels are found but some other transponders get missed. I don't think it's a signal problem as it always misses the same transponders.
There is another issue with the channel scanner. Not sure if this belongs into a separate ticket: If I start the channel scan a second time without restarting mythtv-setup, it gets lots of conflicting channels and asks me to asign numbers to them. This does not happen if I restart mythtv-setup after every scan.
Tell me if you need additional information for this?

I have the same problem and attached a log from 'mythtv-setup -v channelscan'. MythTV does find all transports but it seems to search for channels only on the first twelve that were found in the first part of the NIT.

The following patch fixes this issue for me. The patch allows the setting of the NIT-ID from the GUI. The setting is available from the videosource settings page.

Added a version of the above patch without the schema change. This is integrated into the GUI and still seems to function. I'm not however sure if this should be done in different classes.

- Status changed from assigned to started
- Milestone changed from 0.23 to 0.24
Bumping this one to 0.24 as we have frozen 0.23 for new strings for translations. As this patch adds a new translatable string it needs bumping.

The attached patch does not seem to work. Scanning here I get two multiplexes inserted for every freq, one with the correct networkid and one without any networkid, none with the networkid I specified.

For whats it's worth. I applied the 2nd patch to my 0.23 branches and it works perfect voor DVB-C from Ziggo The Netherlands

I've applied the patch to mythbuntu 10.10. Besides one single line in dvbstreamdata.h the patch does still apply without other problems. This line could easy be added manually. The patched mythbuntu backend does find all channels without any problems in the Cablecom network in Switzerland. There have been some channels that where reported as duplicate, but all other channels are working. Let me know if you'd like to have further infos.

The patch can be applied on trunk svn 26882 with manual editing of dvbstreamdata.h. It works OK on cable network Ziggo in the Netherlands.

Too bad this got bumped to 0.25
Klaas, which of the 2 patches did you apply to 0.24 trunk? With or without the DB schema change? Could you post your amended patch here, or elaborate on your manual edit. I, and probably many others, will be using the patch on the 0.24 fixes until 0.25 arrives.
Thanks Guys, it works great.

This issue is over 4 years old (it replaced an older issue for some reason). It prevents me from using MythTV, since it cannot tune all my programs in Denmark. I really hope to see this in 0.25
