NextPVR on Raspberry PI 4 having issues with mycloud

[DavidD]

Hi there,

I am using the latest version of Raspberry OS 32 bit and the latest version of NextPVR. I am trying to record and watch tv using my WD Mycloud as a recording storage/mycloud. I have successfully mounted a wd mycloud share using the following line on my fstab file -


//192.168.0.118/NextPVR /home/pi/wdmycloud cifs username=pi,password=*******,workgroup=WORKGROUP,file_mode=0777,dir_mode=0777,uid=pi,gid=pi,forceuid,forcegid 0 0

This is a public share.

It works fine as I can write to the share no problem from the raspberry pi. When I try to watch a channel though I get a Failed to start requested them error.  Here is the error that shows up in the log.

021-06-07 19:26:31.761 [ERROR][24] Unexpected error creating TSWriter map: System.UnauthorizedAccessException: Access to the path '/live-CBOT-DT-603-1.ts.map' is denied.

I cannot record anything either.

I also tried in accordance to another thread that I saw on the NextPVR blog to change the credentials under which the service runs from user nextpvr to user pi group pi - but that never worked. I got some kind of internal error on the screen and here is the type of error I received in the log.

If I do not use the wd mycloud to record/watch tv, NextPVR performs fine. I even tried unmounting the wd mycloud from the pi and tried to write to the same directory to which the wd mycloud was mounted and it worked.


I am far from an expert in Linux. I have spent way too many hours on this issue and am just about ready to give up on it. Anyways, any help you can give me would be greatly appreciated. Thanks.

It feels like your live buffer folder is incorrect, possibly set just to / Please upload you zipped logs and I can have a look.

Thank you for your quick response

I could not record to / . I got some kind of transcode error. So, I unmounted my wdmycloud and tried to record to the directory to which I normally mount the wdmycloud. This worked except I could not watch tv and record at the same time which could be because I am on a low powered Raspberry PI 4. I can live with that. I am afraid I cannot attach a zip file. Everytime I drag and drop the file, the browser would like to open the file for some strange reason. I have tried the latest version of Chrome, Edge and Internet Explorer. Is there an alternative way to send you a log or do you know what I am doing wrong.

Thanks,
Dave.

Instead of dragging and dropping click that region of the forum and you will get a dialog to attach a zip file. Failing that use cloud storage (Dropbox, Goggle Drive, and OneDrive)

You shouldn't be able to record to / on linux,

Don't expect to watch anything in the web browser using the RPi, you would need a direct play client for that. That would be Kodi, or dedicated apps for Apple, Android or Roku.

Thank you once again. Here is my log.

[mvallevand]

That's not really what I wanted. I asked for the zipped logs which you get from the Settings page as explained on the wiki for support.

However I can see another issue, it doesn't look like CBOT (I live in Ottawa BTW) was mapped to any available tuners perhaps because of the failed attempt to write to / so that would have been on problem for a while. I figure tuner1 was locked and you would have needed to restart the server to free it.

As expected transcoding is bad. 1/3 real time for CBOT and CJOH will be worse. You need a direct play client.

AFAIK you should be able to recording to a properly mounted share. I suspect if you find the gid for the video group and use that in your fstab you will be ok.

Ohhhh, another Ottawanian - good to hear. Thank you again for your response.

Here is my zipped file again. I am not sure if it has what you want to look at though because I deleted some of the .1 and .2 logs just to try and simplify what you were looking at because I had been trying so many different combination of things.

How do I go about finding the gid for the video group and are you talking about finding the gid on the pi or the wdmycloud? Do I replace it the gid=pi in the /etc/fstab file. The directory that I am using in the WD mycloud is designated as Public.

I had this same setup working (at least I thought it was the same) on a previous version of NextPVR without the video gid. I know I did have it working without the video gid. Unfortunately, I do not know what version it was.

Thanks,
Dave.

I was only throwing that out there (with the example command to find it) if it worked before it will work again, the file system has nothing to do NextPVR. In fact I have a policy about not support users with Linux and I've already gone further then I should. The RPi is a learning device for a reason.

Also I have yet to see a log where you actually used that folder with a share or used direct play client (Kodi on Raspbian is not great BTW) so I think my work here is done.

Hi,

Thanks for your help anyways. I have spent many thought this might be out of a lot of people's domain of responsibility. But I was kind of desperate. As I said, I have spent several hours trying to save this issues.

I did not send you the logs with me trying to share the drive because I had tried so many different things and thought it would be confusing to troubleshoot. So, I was only giving you what I thought you were asking for. I thought you wanted to troubleshoot one step at a time by just trying one simple operation at a time and then looking at the log.

But I do not blame you for spending more time on this case as I have already wasted way too much time. I am thinking of just buying a drive to attach directly to the pi to simplify things instead of recording to a NAS.

Thanks again for attempting to help,
Dave.

Maybe I'm confused since I thought the only issue now recording to the share.
