Error streaming channels with channel name containing international characters(v5)

[fwpvr789]

Hi,

This issue has been there since the very first v5 release I installed and it doesn't exist in v4. Basically if the channel name contains international characters (e.g. Chinese), the server has issue to parse the *.ts.map file which in turns fails the streaming process. I have changed all the names to English letters and have been living with it hoping this will be resolved in a couple releases. However, until now it seems no one else has reported the issue. I think it's the time I bring it up.

I have a channel named "CCTV-1综合HD", you would notice two Chinese letters in it, when I start streaming the channel, NextPVR runs into the following error in the nrecord.log. further investigation revealed that it tried to parse a file called "live-CCTV-1综合HD-20688-4.ts.map" but failed. However if I removed the Chinese letters from channel name, the error went away and the streaming was fine. I believe it's an encoding support issue. Hope Sub and/or Martin can address it. Thanks a lot!

I don't think we've got many non-English users here, so no one has probably notice the problem before.

Are you using xmltv for you guide? If you can supply a sample EPG file, I check it here.

[fwpvr789]

Yes, I am.

here is the sample EPG file including a few programs for the channel I mentioned. and the Chinese names work in v4 but not in v5.

<?xml version="1.0" encoding="UTF-8"?>
<tv generator-info-name="****" generator-info-url="****">
  <channel id="cntv_cctv1">
    <display-name>CCTV-1综合HD</display-name>
  </channel>

You typically need to zip any files you want to attach.

Actually - sorry, I misread. I thought you meant it was the characters in the EPG. I now see you mean it was the channel name. I'm checking.

It's funny google is now show me adverts with Chinese characters...

I've found the cause. The attached updated NShared.dll fixes the issue.

[fwpvr789]

Wonderful! The issue is fixed. Really appreciate your quick response and hard work!

BTW, I liked all the features that NextPVR provides, particularly how it can be customized to stream and record all kinds of IPTV sources. I have created quite a few tricks to use your software to get what I want and I haven't found any other PVR software that can replace it yet. that being said, if you can implement the channel import/export feature as discussed in the following thread, it will be perfect (or is there alternative way to do it in v5?) but no hurry, it's surely not the highest priority for you. thanks again!
