Stuttering on LiveTV (4 Viewers)

[mrkk]

Hi

tested romadd64's tsreader.ax its better than before, but not as good as on RC1 19228 build...

Tested on Vista 32-bit with RC2.

Don't know if I'm suffering of the same problem (See my thread: Hauppauge HVR 1300 - analog TV stutters - MediaPortal Forum), but I have installed the TSReader Patch and the stuttering is more or less on the same level...

If anybody had an idea how to fix our problem I would be very thankful! Because I am desperating at the moment -.-"

tested the patched tsreader: no more stutterings, only a few, nearly not remarkable pixel-errors, much better than original RC2-tsreader.

Hi all

Sounds like i might have to make the time to make the jump to RC2 this weekend and see how it goes as well.

Non SVN version

Will the modified TS reader work with the 1.0 RC2 non SVN version? Or will it only work with 19778?

Im having the same trouble, but just with channels I have poor reception for.

Cheers

Current TsReader version drops those packets that are determined to contain discontinuities. This is done to make sure that MPEG2 decoders arent crashing (there are many cases that partly corrupted stream is crashing the MPEG2 decoders & MP).

Only correct way to solve the issue is to try to find the real cause for those discontinuity errors.

Tourettes,

I know that it’s correct to remove packets containing discontinuities, but could be fine to introduce a choose in the configuration for tsreader behavior (to drop or not to drop). Who chooses to not drop packets with discontinuities does it at own risk (it could be remarked in the configuration page).
I have a Skystar2 that has discontinuities on some channels and I have not found a solution (and it's not a low signal problem, with its sw it has no problems)
Should I change the SS2 with another product, or wait for a sw fix (TVE3 or SS2 drivers - who knows ?), or is it better to permit to relax the tsreader behavior ?
As you can see, there are other guys with the same problem.
I have tried my modified tsreader (very little change in the source code for not drop discontinuities) for days with MPV/MPA with no crashes.

Just my two cents.

Thanks,
romadd

I'd like to second that. If the new behaviour (dropping whole frames) would be the default one and the config option would be visible only in expert mode, everyone could be pleased very well. Newcomers wouldn't be bothered by possible crashes and long time useres would have the chance to decide for themselves whether they prefer maximum stability even with faulty codecs or less stuttering.

Hi All

Yet Again...

Ok, sadly now i am more confused than ever and back on RC1-19228.

Made the jump to the latest build (rc2+SVN) with the expected result of stutters on several channels especially the ABC which for me seems to suffer worst from this. I then changed the tsreader for romadd64's fixed one. This has helped. Especially for the channels that weren't too badly affected but my ABC is still totally unwatchable (sometimes).

Now, the bit that has totally confused me is that it is not doing this all the time! If i tune to the ABC once it may be ok. If I then go to another channel and come back and it will be unwatchable. Away and back ... maybe unwatchable who knows. About every third time or so i tune to the worst channel (ABC) it is perfect and every other time it is rubbish. Go figure?

Just in case anybody has any bright ideas, i have attached some logs. In this case I;
#tuned once to the ABC = Stutters (unwatchable)
#went away and back to ABC = Stutters
#went away and back a third time to the ABC = A perfectly fine picture

The other weird thing is if i hit pause for a second or so and then play, it is then ok???

Anyway, as I said I'm a bit confused now, maybe I have something else stupid going on. At lest I'm getting better at the whole uninstall and reinstall process. Have rolled back to 19228 and all is ok again.

Keep up the good work all!
Regards

ps. I also would support the configurable option of dropping dirty packates.

So I had a chance to do a quick test last night with the new TSReader. I apologize as I think this needs (at least on my part) some thorough trial and error, but I just haven't been home. I might have some time this weekend, so I'm hoping to try the new SVN or roll back to the RC1 SVN from may that some are saying has been stable.

For me, this new TSReader is better while actually watching the channel/recording, but I get a crash when a new recording starts.

I had several recordings setup last night, and here's what I did.

Attempt #1... At about 8:43pm I got home and started to watch a recording that was still recording (TV > Recorded TV > chose the show) from 8 to 9pm an SD channel. This was fine for a few minutes (RC1 this worked, RC2 this did not) until the next recording started at 8:45pm from an HD channel. MP just froze up. I gave it a while to see if it would recover (tons of "TsReaderPlayer: OnVideoFormatChanged" messages), but it didn't so I started pushing buttons and eventually had to forcequit. I think CPU usage was up, because the fan came on (it normally doesn't). And then there are a bunch of exceptions in the log.

Attempt #2... I went to recorded TV and started playing the recording that started at 845pm (in HD). This I watched no problem at all (again, RC1 was able to do this, RC2 was not) until the next recording started at 9:58pm (actually 10pm with 2min pre-record setting) on an SD channel. Same thing again. MP froze up. This time i immediately hit stop and after a minute or two it came back, but MP was all slow so I had to close it and open again.

I don't remember which time (or maybe both), but TVService crashed and had to be restarted.

Logs are attached.

======
@everybody - When you guys see stuttering, do you get the "TsReaderPlayer: OnVideoFormatChanged" message? or is it only continuity errors? I occasionally get continuity errors, but pretty few and I want to make sure we all have the same problem so as not to throw the devs in circles looking for one fix to multiple problems.

I'll try the new SVN this saturday (I'll make the time, darnit! ) and if that doesn't do it, I'm going to roll back to that RC1 SVN.

Yep, same problem here in germany for me with "Pro7" :-( This evening i will try a new channel-scan and i will report, if it helped.

Sorry, no, never sen this message here before / after stuttering.
