No video/audio detected (3 Viewers)

[Fredd_1001]

If tried your suggestion, but nope. Still NO video/Audio error.

Allso with the latest SVN builds where we have the possibility to configure the waiting time for timeshifting/unscrambled the problem persists. I've tried different settings, but I see no effect at all. I can set the time for timeshift as long as possible, but at the end of that time still the NO video/audio message.

well, setting those values to something higher is only meant to help people out with slower CAM's etc.
If this is not your problem, then all it does to you is making the client wait that longer for the "no AV err. msg."

My "No audio/video detected" problems seem to be gone after changing timeshift files folder to harddisk with quite enough space (tens of gigs).

The problem is still that sometimes Mediaportal creates too many (more than allowed in configuration) timeshift buffer files but it doesn't cause any problems because there is enough free disk space. I haven't bothered to check out log files if there are any reports of failed deletion of buffer files but I guess some locking prevents those to be deleted sometimes.

Perhaps I have found a reason for this error on software-encoding analog cards. Sometimes it's very important to use the encoder that it is delivered with your card. For example my HVR-900 only works with Hauppauge encoder and not with the Cyberlink encoder which is also installed on the system. Therefor I have created a feature where you can specify the priority of the encoders to ensure that you are using the right encoder.

I tried MisterD's suggestion above, and bumped up the priority of the Hauppauge encoder over the Cyberlink's ones. Unfortunately, it didn't get rid of the "no video/audio detected" error which was popping up when I first started My TV.

The later builds of TVServer may have changed something for the better, because after getting the above error after starting My TV, if I click OK to close the error box, then go to start TV again, everything would work fine, until I restart MP.

I can't be absolutely sure, but MisterD's patch seemed to speed up channel changing.

I reverted back to bumping up the Cyberlink encoders, since the Hauppauge ones (Mainconcept) were producing a pretty bad audio/video sync problem.

Since trying MisterD's patch, I have uninstalled TVServer and installed the next build, which presumably overwrote the patched files. I also assume that whatever changes were made by MisterD's MSSQL script remain.

My error problem did disappear, BTW. I had seen a message from someone here about resolving this by adding an external drive. I tried it with my NAS, but it didn't get rid of the error. Yesterday I plugged in a 250GB external drive, set TVServer to record and time-shift to it, and the error went away!

It may be a combination of the drive and MisterD's MSSQL script, or who knows.... What does the script modify, BTW?

The issue now is, that after turning on the TV everything is good, but once I change channels, the audio and video go out of sync. Changing decoders around helps a little, but it doesn't make it perfect. The only way to resync, is to stop TV, then start it again while at the new channel, and then it's perfect.

Any ideas how to fix this?

(I am using Hauppauge PVR-950 with Vista.)

audio video synch issues are often b/c audio renderer isn't setup as "default directsound device."
try that.

Thanks, gibman.

In my case, the audio renderer isthe default directsound device, so who knows what the problem is (I am trying to figure out if the MSSQL script may have changed something.)

Also, my "no audio/video detected" error is back at the start of My TV:-( It seemed to come back as soon as the guide populated. As before, if I click OK to dismiss the error box and then go and turn on TV again, it starts working (but with the sync issue after channel changes.)

Just in case it shows something useful, here are my logs.

I'm, everything is really quicker here!

I reverted back to bumping up the Cyberlink encoders, since the Hauppauge ones (Mainconcept) were producing a pretty bad audio/video sync problem.

Where you found the Cyberlink encoders ? I'm not able to downlaod them from the wifi page link...

It only create a new table, so it cannot be of any help/trouble...

Can you wait for let's say 10 seconds after a switch and ses if audio goes ok ?
It sometimes happen to me too, but I'm quite sure that it's a codec issue...

My MSSQL script just adds a new table to the db where the encoder filters with their priorities are stored. When you switch back to the original file the old behavior is also restored, because the priority is hard coded in the code. So the script has no affect, if you switch back to the original files.
