Bug #5500
Recordings wrong when using Fritz!Box's DVB-C tuners
0%
Description
(This might be quite long, but it's a strange problem I've encountered, so please bear with me).
I've got recently a Fritz!Box 6490 and tried to make the DVB-C tuners works (in addition to my USB tuners). At first it looked like it would work, no problems were reported, however, the recordings (in mkv format) had some serious issues - apperently the indexes were screwed. For example:
1.) One recording had a runnimg time of about 1:30 minutes, the movie in question was longer - it had a correct beginning and the credits were OK too, yet the running time was wrong
2.) Even though the recording went OK, the other movie just ended at the last third.
3.) Now it's getting really bizarre: Two other recordings had serious forwarding/rewinding issues. For example, if I forward to 5 minutes suddenly I'm at the end of the recording (although the time index says 5 minutes). A little bit further forwarding will go to the approx right position, I'm trying to rewind (say 30 seconds) I'm getting forwarded, and similar odd effects
Note that when using the USB Tuners, there's no such strange behaviour - only when using one of the Fritz!Boxes DVBC-Tuners.
Has anyone encountered something similar?

Updated by Do you have some data errors for the DVR entries or continuity errors in the logs?
Updated by Mark Nowiasz almost 6 years ago
Updated by Yes, but varying - from 0 errors to 20, one of the "odd" recording had none, the other one only two. THe USB tuners also report roughly the same continuity errors without the effects mentioned above, these are strictly limited to the Fritz!Box DVB-C streams.
However, I do get some odd messages in the logfile:

Updated by Does the 6490 have firmware 7.01? Did you assign different ip adresses for each tuner? I also use 6490 and have no problems with recording on a E2 Box (TVH running on Pi2)
Updated by Mark Nowiasz almost 6 years ago
Stephan Gradl Mees: Nope, 06.87 (this is a Vodafone/KD Box). About the different addresses: I tried it out (DVB-4, using a different address). If worked at first.. however, when I tested the setup by recording 4 different channels (on 4 diffeent muxes), suddenly all 4 tuners where having serious data errors, so I switched it back to the default setup - 2 tunes, one IP.
Where do you set up this payload? Haven't found a setting in the DVB-C-tuners..

Updated by The issue with 4 Tuners at the same time having issues is known by AVM and has been fixed in 7.0 (I was the one who was constantly bothering them for one year straight until they finally fixed it), it is due to the completely weird way the cableinfo daemon which sends the data behaves. You can not watch more than 2 HD channels at the same time (or more specific, if you exceed 25Mbit/s you will experience packet loss). In 7.0 this issue has been completely resolved and 4HD Channels work perfectly fine.

Oh I forgot: You can not have multiple tuners on one IP, that will not work with the box. Use 2 tuners on 2 IPs, that should work.

You find payload under
General/Sat>IP Server/RTP over TCP Payload
With the default value 7896 i also had several stream abortions.

Not exactly. This is true if you manually select "DVB-C 4", but if you revert/leave it the way it was ("Auto"), both tuners work fine using one IP (apart from the problems I mentioned, but these also occured in DVB-4 mode)
Updated by Flole Systems almost 6 years ago
The "problems" involve that the second stream drops and only one of them is sending data, this is not what I would call "2 streams working". If the channels are on the same frequency it will work, but that is not a second stream so that doesn't really count.
