NextPVR Forums

Hi,
I just set up NextPVR on a Raspberry Pi 4B, HDHomerun Duo and Roku TV. I am so impressed by how much nicer the NextPVR interface is than the HDHomerRun app. However. When I'm watching a channel with marginal reception (a little pixelated but totally viewable) The Stream stops and displays the error: "-5 malformed data" then goes back to the NextPVR menu. I think this might be just with the Roku App. But it could be more general. 

Here is the NextPVR log:

Please post in the appropriate sub-forum and attach the zipped logs not snippets. The error seems to match the scenario though, the Roku player is not very sophisticated and even on the Silicon Dust forum they note issues using Roku player. If you had a more powerful server you could turn on timeshifting since the m3u8 transcoding might smooth out small rough areas but you don't have that luxury. Any followups should be in the Roku sub forum here.

Do you only get this when trying to watching Live TV? Or does it also happen on recordings from the same channel? (There are several things behind the scenes that work differently between playing a recording and watching live.)

Also, have you set up NextPVR to do a remux to an .mp4 container in your postprocessing script file? The Roku handles the .mp4 container better than the native .ts container that NextPVR records.

@mvallevand Thanks for the quick reply. Sorry for the long dump. I'll do zips if logs are needed again. Searching through the forums the -4 error didn't show up, but I'll look for specific SiliconDust subs.

My current setup is with RPi 4b 32 Gb SD card. Tried a 64G USB SSD Drive and mapped "recordings" folder there, but the performance with that was worse. I ordered a 1T M.2 with USB3 adapter to give that a try for recordings. I also ordered a new Rock Pi 4B with built-in M.2 adapter which should be much faster. I'll try doing the timeshift when I get that. But it'll take a while to get here. Do you know if enabling the Video Codec (small fee from to Rpi) would help with the transcoding?

A quick look at htop seamed to indicate that the RPi was only using less than 20% of the 4 cores. While playing back live TV.

@BrettB Thanks for the suggestions. I tried a little playback and it seemed OK. But, I need to wait until I get more storage before I can do a real test, 32G SSD isn't cutting it. Is the remux to .mp4 the same solution as @mvallevand with timeshifting? Sorry, still new to NextPVR.

That is a Roku error with bad video files so the only solution is providing a cleaner source

The speed I am talking about is the optional timeshfited play. I expect your CPU would be much higher transcoding to h264 but it does help to fix some stream errors. I don't expect the Rock 4B to be much better then the Odroid N2 which isn't fast enough. I didn't order 4B yet but I do have the $5 pre order coupon.

Also make sure you pay attention the other threads on Roku sunsetting private channels like the NextPVR channel.

I saw the Roku thread. I feel bad for you! You put all that work into it and they just squash it. Jerks. I'm a developer too. Doing something similar to replace the iOS app for my car because Ford can't write software. But they could just change one little thing and completely deny me access to their api. I have a Roku TV and TV w/ roku stick RN. But might look for the TVo 4k thing and jump ship before I sink too much time into this thing. Roku has been getting on my nerves with the adds etc anyway.
I'll post on Roku's form but I feel like it's shouting into the wind sometimes dealing with these companies.
I'll post a review with the Rock 4B after I try it.

The TiVo has a great remote because of the number keys and it is on sale right now, but don't expect much in the way of firmware upgrade. The remote will be good in the future.
