Hi All,

I need some help here. I installed Nextpvr. Everything is working perfectly. I can record fine.

However when i trie to play something that i recorded in the webui of Netxpvr it always tells me "Failed to start requisted stream"

If i play the same with vlc its working fine. (so the files are fine)

What could be the problem?? I would love to watch my recorded items true Nextpvr webui.

The web playback is only really useful if you have a PC powerful enough to transcode in the background of if the source files are compatible with a browser. It could also be that you have tried to turn on h/w trancoding and your PC's video card don't support that. If the linux your are using is on an RPi you wouldn't be able to use the web player for playback.

Upload you zipped logs and we can have a look.

Hi Martin,

Thanks for your reply. First of all i am a starter with Nextpvr. I will try and explain wat my setup is.
I am running nextpvr on debian inside a lxd container. I use the videocard with hardware passtrugh. i can see the videocard inside the lxd container so that should be fine.

The videocard i am using is NVIDIA Corporation GK208B [GeForce GT 710] (rev a1)
I also attached the log file.

So you are trying VAAPI not software transcoding and that is definitely failing, maybe software decoding will work.

Also consider playing with this command line to see if you can find the error. You could use an override.

Code:
sudo -u nextpvr ffmpeg -y   -vaapi_device /dev/dri/renderD128 -i file:"/home/records/Gordon Ramsay Oorlog In De Keuken/Gordon Ramsay Oorlog In De Keuken_20211007_18301930.ts" -map_metadata -1 -threads 0 -ignore_unknown -map 0:v:0? -map 0:a:0 -map -0:s -vf "format=nv12,hwupload,scale_vaapi=w=1920:h=1080:format=nv12" -codec:v:0 h264_vaapi -max_muxing_queue_size 2048 -b:v 8000000 -maxrate 8000000 -bufsize 16000000 -codec:a:0 aac -strict experimental -ac 2 -ab 192000 -hls_time 5 -start_number 0 -hls_list_size 0 -y "/var/opt/nextpvr/web/temp/Gordon Ramsay: Oorlog In De Keuken-06395a260ad445f59f2b91e175a99a67.m3u8"


I am not sure why this is even being transcoded, but that is a different question for sub.

On the Settings->Transcoder page in the web app, make sure you have ''Video Encoder'' set to CPU

It's complaining it doesn't like something about the file. Are you able to put a sample recording somewhere like onedrive or googledrive and let me know the download link so I can check it out here.
