Experimental TsReader development (2 Viewers)

[IanJ]

V34 solid here.....glitch free on channel changes.....well impressed!

Have tried a bunch of channels and no corruption seen thus far (1hr).
PS. Am using MS codecs for TV/Video, and FFD for audio. I'm using SAF5.

Sometimes I still have this problems, when tuning a channel the 1st time: no video/audio for a while, after 10sec audio appears.
Using UNC, tsreader0034.

Re: AW: Experimental TsReader development

As promised two trials with logs, just 5 mins as I could quickly reproduce the (video) corruptions with worst case scnenario Discovery HD of German SKY.

v34, roughly from 1845-1850
Video corruption the whole way through also stuttering, skipping gave a short relief at best, CPU was hovering around 75%.

v33, roughly from 1900-1905
Some corruption starting around the 3 minute mark on and off, CPU at around 85-90%

As I said worst case Discovery HD, I can watch other 1080i channels like ESPN America HD without a single corruption or stutter (besides a few cases when changing channels) with v33 and LAV software decoding. With v34 I had corruption on those channels as well.

I'm surprised it's actually watchable (there are huge numbers of late video samples in TsReader logs) - is the audio in sync with the video ?

Can you do a set of logs using the standard MP 1.2.1 TsReader.ax (with Discovery HD) please ?

Just wondering why you don't use a DXVA video decoder ?

Haven't had this in 33 or 34 at all yet but it was rife before then. Trick for me is to tune an FTA SD channel first if you've just booted or restarted the TV server or had it idle for some period of time.

I'm using Argus with md***plus. No, that's something else...using rtsp doesn't cause such a thing.

There are some 10 sec timeouts in the code in various places, so next time it happens can you grab a TsReader log and I'll take a look ?

To make Tony's job easier, please use only TVE3 and FTA to rule out any 3rd party caused issues.

Hi Tony,

Question1: I have seen some corruption ones in a while. No freeze or problem just some corruption. I think it's because of some discontinuities. What i am seeing is that audio is not in sync anymore after the corruption. Mostly it's ok and the tsreader can survive some distortion. But in case of harder curruption audio/video sync is solved by stepping back -15s.
I believe the video stream is continuesly monitored for audio/video sync or not?

Question2: Are discontinuities always comming from tswriter/cam or is it possible that the optimalisations the developers make to mediaportal could generate some?

Greetings,

Wouter

Q1. Is this a new problem with v34 ? Which video/audio decode filters and audio renderer are you using ?

Q2. The TsWriter log should show received signal discontinuities. Client/Server systems using RTSP can also have discontinuities caused by lost network packets.

Tony

Microsoft video codecs, ffdshow audio codecs, mpaudiorenderer. Maybe it's because of the last one. I hope Tourettes will pick up developing it. Can you?
I'll try to figure out which one gives the best results 33 or 34.

I'm pretty sure it's Mediaportal Client related - I'll post some logs tomorrow.

I did some tests on another computer today with v34. On this computer, TV video sometimes freezes after 1 second, audio continues. This only seems to happen with channels where the CI modules is used. Please note that I had some strange behaviour with the CI module already in the past, but the same problem does not seem to happen with TsReader from MP 1.2.1. Perhaps you can see something from the logs (happened at last channel change in the logs). Thank you very much.
