Watch now issue

[bader77uk]

Installed Version: 5.0.6.200614
Ubuntu 16.04 LTS

NextPVR running properly and TV Guide with EPG loaded fine.

there is channels i can watch now (live streaming) and its playback properly in NextPVR

issue #1
some channels when click 'Watch now' i get error: Failed to start requested stream
Note: i have tested the streaming links in VLC and its playback properly so its not the provider issue

issue #2
Recorded streams stored in default path but unable to playback in NextPVR i also get error: Failed to start requested stream
Note: when i downloaded ts file its playback properly in VLC

looks like issue with ffmpeg argument command line

i have attached logs.zip with two log files regarding the issues

Appreciated you help!

You turned on h/w transcoding and are getting ffmpeg errors. Do they work with just s/w transcoding.

Normally you need to attach the zipped logs from the web browser, you shouldn't typically get this stdout on linux unless you are running in a command line.

Thanks for your reply. i think ffmpeg arguments needs correction for playback recordings. also i hope to add an option to playback recordings in original without transcoding. am awaiting for developers reply

[mvallevand]

I am used to people installing as a service and using the deb installer but I suspect there could be another issue, since your file doesn't need transcoding. Perhaps you missed installing some of the required linux requirements when you did a manual install.

Also many users prefer direct play clients like Kodi to avoid extra processing.

If you must use transcoding you can override the command line in config.xml until sub can look at it. The default is mainly tested for mpeg2 to h264 and not cases when transcoding isn't a requirement.

First thanks for your quick response.
actually my user privilege in Linux server doesnt have sudo permission so I am limited on installing and running such program like Kodi I have tried many hours to get it running but too much missing libs so I gave up on it.

now NextPVR is much simple to install and run in the Server

I have upgraded to latest version and now one of the issues has been solved

I am still unable to playback recordings due to ffmpeg transcode argument and I have checked the config.xml and found that Is possible to override the argument command line but I'm not sure what exactly I need to edit so I prefer a developer advise on this matter and also I'm afraid if the same argument is also using for live streaming

[mvallevand]

Without sudo are you able to install all the requirements here https://forums.nextpvr.com/showthread.ph...#pid523886 The mediainfo binaries are going to be required and will help you out a lot. Also are you sure your ffmpeg is update to date?

You could change TranscodeHLS from default to your custom setting to see how it work. It will be used for live streaming. too.

However as @shspvr pointed out your file may not have audio can you play your file other ways, perhaps
