Bug #1385
US ATSC Transport error indicator
0%
Description
I'm attempting to use tvheadend git rev aecded7c4e on a raspberry pi with an Elgato EyeTV Hybrid. The hardware appears to be working but no Service names appear in the GUI and moreover attempts to "Play" a channel result in "Transport error indicator." I'd like to help debug but I'm not sure where to go next.

I can use azap to tune a channel:
$ azap -r OPB
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 195000000 Hz

I can then successfully play the resulting mpeg transport stream with omxplayer (a video player specific to the raspberry pi that uses its onboard hardware acceleration):

This goes for a while until "Map DVB services to channels..." is no longer greyed out. I click it.
The following screenshots show the results: no Service/Channel name information even though this does show up in the w_scan output.

Updated to 03f7bc1... and set "Full mux reception" to "Off", deleted .hts directory and rescanned as described before. Still no service names in the Services tab, and no channels are created. However, MuxIDs are present. I can begin streaming a channel to VLC using the Play link. However, after a few minutes of (somewhat choppy) streaming, I get:

Any suggestions on how to debug? Thanks for your help so far.

At the moment I'm stumped. We've been having all sorts of probelms with HDHR devices though 
But this looks somewhat different to other reports. It looks to me like something is going wrong with the signal, though I could be wrong.
Just to confirm you get the transport error constantly outputting after the point where the stream stops? That definitely suggests something wrong in the stream (OR tvh has done something very wrong indeed).

Updated by Christopher Mason about 12 years ago
Correct: if I get any streaming at all, then very quickly I see Transport error indicator and the stream freezes. I don't think this is a problem in the stream. I've been experimenting with sending using VLC in order to confirm that reception and networking works.
cvlc -I ncurses ~/.azap/channels.conf --sout "#standard{access=http,mux=ts,dst=:8081}"
The DVB reception seems to be perfect. If I use VLC and an ethernet cable between the raspberry and my mac, I can stream perfectly, every time. Using http and an unloaded wireless network (150Mbit or 300Mbit 802.11n) usually also works. Interestingly, vlc also complains about some stream problems, but it seems to recover better. Early in the stream, VLC often says:
libdvbpsi error (PSI decoder): TS discontinuity (received 14, expected 0) for PID 0
libdvbpsi error (PSI decoder): PSI section too long
libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 15) for PID 0
libdvbpsi error (PSI decoder): TS discontinuity (received 13, expected 0) for PID 48

However, vlc seems to recover, and continue to stream. I only see these messages very early in the stream, and after that it works perfectly.
In tvheadend, whenever I see "Transport error indicator" or "Continuity counter error" the stream stops playing and it basically never recovers. Often this happens immediately on starting to stream so I never get any video. For example this case:

[Hangs, no video streams.]
I stop tvheadend, fire up the vlc command above, connect to port 8081 and it streams flawlessly.
I'm guessing maybe tvheadend isn't recovering gracefully from whatever TS discontinuity happens early in the stream. Total guess but maybe the receiver produces some garbage early in the stream? vlc (really, libdvbpsi, I guess) recovers from this but tvheadend does not?
Finally, I still never see any Service names in tvheadend and no channels are mapped; I never get any program guide information. Is this expected?

I might having a similar problem. I'm in Quebec, Canada and I have the same behavior with TVH / HDHR3. After scanning the mux, I have 27 services but they are unnamed exactly like your screenshot. And then mapping dvb services to channels just does nothing

Can you please confirm whether this is still happening. I really never got my head around what could be causing this. TVH should properly handle problems with sync in the TS stream these days.
The only other thing I can think is that TVH is somehow passing the incorrect tuning parameters? Or possibly there is a problem with DVBv3 commands and the VLC stuff is using v5.

Allright, I just redid my setup with HDHR and TVH and the channels are there, finally!!! Now I have problems with EPG, there is nothing working for EPG Grabber, or I don't know what to do. I'm with a OTA HDTV antenna, i've tried to checked all the OTA grabber but it's doing nothing.
Thanks

I don't think that most US providers are using standard EIT, somebody did start putting together some stuff to process some US provider tables but I've never actually received any updates.
You're best bet is probably XMLTV (I think schedules direct provide US listing, though I don't think its a free service). Might be worth asking on the general forum.
