LiveTv Channels - Streaming Failed (transcoder exited)

[groenator]

I am using nextPVR in a docker container with the official nextPVR image.

The docker container runs inside Ubuntu 18.4 LTS. 

Before I start explaining, this behaviour only happens with some channels. Other channels are working fine. 

The behaviour I am having is as follow:

Whenever I start playing a channel (Boomerang) from my IPTV via the NextPVR Web UI I am getting the following error:

Code:

Streaming Failed (transcoder exited)

If I am playing the same channel using Emby, the channel at first stops for about 10-30 seconds, then it starts playing as normal. 

I played the same channel with Kodi, the behaviour is the same as with Emby. 

When I played the same channel with Android TV or Mobile I am getting the same streaming failed error. 

Another issue I am having is with recording. When I record from this channel the recording is broken. I can only play the recording with Emby and Kodi but not with any other players, like VLC. At the moment I am not sure if the recording issue is related to my main issue.

I uploaded the logs from Emby and NextPVR.

From the previous discussion we had, you said this has to be something related to FFMPEG. 

I also tried using HW encoding, I thought maybe it will help to transcode but it didn't help. I remember you saying that this is nothing to do with HW. 

If you need more logs or investigation please let me know. 

Thanks again for your help.

Sorry those are edited logs you need to send all the logs for a real look but going back to the last thread did you confirm

/buffer/ is setup correctly?

If you want to PM an example url that doesn't work, I'll check it here. It's not uncommon for IPTV providers to do weird stuff that needs special handling.

Hi, 

I attached all the logs. I configured buffer based on the documentation. 

Code:

version: '2.4'
services:
  nextpvr:
    container_name: nextpvr
    image: nextpvr/nextpvr_amd64:stable
    restart: always
    privileged: true
    devices:
      - /dev/dri:/dev/dri
    network_mode: "container:app"
    volumes:
      - /nfs/recordings:/recordings
      - /nfs/recordings/buffer:/buffer
      - /data/media/nextpvr:/config

Thank you!

Ok it seems that you aren't able to connect to all the URLs

2020-10-04 16:20:34.061 [DEBUG][46] WebException: System.Net.WebException: The remote server returned an error: (403) Forbidden.
at System.Net.HttpWebRequest.GetResponse()
at NShared.IPTVRecorder.ConnectToURL(String url, Int32 depth)

and at least one worked SuperSport Variety 2 seemed to work which I don't believe you mentioned.

So it isn't the buffer, it seem like it is your URL's but the PM to sub will help

Hi Martin, 

This issue happens only with some channels, other channels are working fine. But one thing I don't get It why the channel is playing well in Emby, Kodi and not in NextPVR?

Have you checked the Emby Logs? The channel I am talking about is Boomerang UK. Please have a look at these logs.

If I would have issues with the URL's then my other 3rd party IPTV players won't work. I am using this playlist with other non-nextpvr clients and all the links are working fine. 

What do you mean "the PM to sub will help"?

As I offered above - if you can PM me the url for Boomerang UK, I'll check it for you (and fix if necessary)

It probably would have worked fine in nextpvr.exe and other clients that didn't need to transcode. Playback in the web app has more things that can go wrong, and it could just be a case of your IPTV provider using some codec or encoding setting that ffmpeg didn't like with the default settings.

Yeah! It does look like that. This is not the first time I see this issue. I know that some clients like android don't support AAC codec. 

Is there a way to tweak the FFmpeg settings? Emby and Kodi seem to play well this type of content, are you able to tweak FFmpeg settings like Emby or Kodi?

The channel is broken now from my provider. I had a chat with my provider, once the source is updated it I will try it out with NextPVR and if I get the same issue I will PM you the URL.
