[confirm] Why oh Why :( Read() no open file (1 Viewer)

[pilehave]

The change i'm making is to create the next timeshifting file before the previous one is completely filled. This should allow plenty of time for the next file to be ready on the network share before it is needed.

At the moment a new file is only created the instant the previous one is completely filled and (i'm guessing) it sometimes takes a little while to be 'seen' on the share which is why it sometimes fails to open.

To ensure that the file is visible on the network, perhaps it could be accessed by the client ie. 10 seconds before it should be visible? This should ensure that Windows has the path cached, right?

Maybe this is already your idea

Hopefully a similar change won't be needed for tsreader, but we'll see how it goes Shouldn't be difficult if needed

OK,

Seems timeshifting to a ram drive does not make a difference with my setup

Hopefully V4 of the patch will be ready soon

mylle, thanks for reporting this!

Iv seen the same thing at my setup for version 1.1.2

Hi,

Unfortunately i've not been able to replicate this problem so can't confirm this will help. V4 of the attached patch contains the code that creates the next buffer file in advance. Would anyone mind testing it to see if it helps and post back either way?

Thanks

Hi applied that patch
and now im geting stops of live tv (using unc)
tsreader log contains new errors

Thanks Romuz, i'll try again

Would everyone mind posting what their network setup is like? Mine's all fully wired 1gbps which might be why i'm not seeing these problems.

Does anyone use wireless or homeplug/powerline adaptors?

 

[romuz]

Mine 1gbps wired too

this errors happens even right after skip back for 15 sec so it is not related with network files caching

BUT imho my main issue related to that tsreader are too close to the end of the buffer
because after skiping back logs like this

it is not produce any visual issues

Would everyone mind posting what their network setup is like? Mine's all fully wired 1gbps which might be why i'm not seeing these problems.

Does anyone use wireless or homeplug/powerline adaptors?

In my case its a 100Mbs wired network. What I have seen is thats its only happens on one of my clients (not tested yet with 1.2a), so I think its due to that NIC.
Could that be the case?
