Great. many thanks frodo.

I can confirm the stream continues since I keep VLC running side-by-side and when MP freezes, VLC continues displaying video. I'll check with VLC if theres any PMT errors or something like that.

As for the other problems on #step3. any suggestions on how to try to identify them?

thanks again.

Frodo, some extra info:

Running MP and VLC side-by-side, I enabled VLC messages and checked some advanced options ( skip-frames and drop late frames).

Here's what happens when I change the channel.

Another interesting point is that I can't really navigate the stream with VLC. If I ask to go to the end of the stream, it gives me lots of messages and en-up with this 2:

main warning: dts != current_pts (-1312818)
main warning: vout synchro warning: pts != current_date (-33367)

And reset's back to the beginning of the stream.

Could this give you some hint?

joboehl frodo

can you make a short look here

At weekend I have made some tests with vlc

Important: You must simulate a channel-change with the tve-timeshift-control, then VLC freezes too.

[josu]

I have looked in details of 1 TV-channel, which makes problems.

ASTRA 19.2, N24, 12480.00 V - Txp:104
PMT 107 !!!!!!!!!!!!!!! from kingofsat


If I timeshift this channel, you can see a wrong PMT of 68

At first look I have problems with the complete transponder 104 and a some others.


Forgot it, I can remind me, that are HEX-values, SORRY

 

[josu]

Why there are different channels in the ts-file, if I rewind ??????

 

[Koschel]

Should be fixed with todays build (12886). Working here nearly perfect

hello koschel,

I am testing it since a few hours and looks good.
Only if you have one client running and the second get connection to the server,
the picture freezes. You must switch up/down and then run the clients again.

- After a channel change, Planescene.presentimage stops being called, and as such framecount is not updated. Framecount in 0 makes code goes down to a path where the "repaint - 0" that most people report as being the last thing before image freezes being called.

Thats normal
Normally what happens is:
1. rtsp filter receives raw data from the server
2. mpeg-2 demultiplexer demultiplexes the stream into seperate audio/video streams
3. audio/video codecs decode the audio/video stream
4. codecs deliver (uncompressed) video/audio frames to the video renderer / audio renderer
5. audio/video renderer present the frame to the user

Now when in step #3 the video (mpeg-2) decoder does not decode anything anymore then it will not deliver uncompressed video frames to the video renderer (VMR9)
MP detects this and will start 'repainting' the last video frame received in step #4 by the VMR9 until the decoder starts to deliver new frames again

So this is the result and not the cause of the freeze problems
The problem is why the process stops in step #1 - #3

It could be
- step #1) rtsp filter does not receive any data anymore (could be checked with network sniffing)
- step #3) video codec does not receive any packets anymore from the demultiplexer
- step #3) video codec does receive packets from the demultiplexer, but with the wrong timestamp
E.g. the video codec expects a packet with timestamp 100.00 but it receives an packet with timestamp 55.00 . In this case the codec drops the packets until it receives packet with timestamp 100.00 and then continues decoding and delivering video frames again

Even worse:
The video codec expects a packet with timestamp 100.00 but it receives an packet with timestamp 200.00 . In this case the codec waits until the current time is 200.00 and then continues decoding and delivering video frames again

Now about the seeking, if you seek fwd/bkwd the entire directshow graph is 'reset' in terms of timing. All filters flush their (internal) buffers and start all over again.. This probably explains why this causes video to re-appear again...

Frodo

Frodo, thanks for that insight.

I raised another thread already, because I am experiencing the exact some problem. I have FloppyDTV, DVB-C, Nvidia gfx, Nvidia pure video codec.

The problem here appears also in normal playback of the recorded movies. E.g. when I play the video from "my videos".

It hangs after a while, and from what you are writting I understand that something in the pipe up to #3 fails.
I could imagine that the recorded movie is broken (maybe due to errors whern recording, put DVB stream should be expected to have errors).

So it hangs from time to time. I observed some occasions where it did restart after a while, maybe the "right" timestamp came around...!?

What can be done to improve this (beside of improving signal quality, I already exchanged al may wiring here)?!

Are the codecs or demultiplexers we use not that robust?! Do we need some preprocessing of the stream?

Maybe the codecs/multiplexers where not designed to handle DVB-streams which come in via antenna and might have errors inside?!
