Possible to record in different format than .ts files?

[mvallevand]

That only changes how NextPVR handles it for LiveTV. That is not the issue, it is your h/w player. I don't think you can get away without remuxing your files. Your file is marked 1080p which is unusual for broadcast but I do remember years ago we had problems with the BBC using a mix of interlaced and progressive video and indeed check with ffprobe this file is a mix. I wonder if this remux creates a playable file?

ffmpeg.exe -y -i filename.ts -vcodec h264 -profile:v high -acodec copy -vf yadif progressive.ts

If so transcoding is slow I'd think about a better player.

Thanks, check out this link for a 1m21s long .ts file https://drive.google.com/file/d/10tZyb6o...sp=sharing
The blackouts are these locations: 31s, 43s, 46s, 49s, 59s, 1m3s, 1m7s, 1m14s.

To follow up on the progressive/interlaced post here are the transitions between the two in your file which do match your blackouts

Code:

"pkt_pts_time": "61382.400789", 0.00
"pkt_pts_time": "61413.640789", 31.24
"pkt_pts_time": "61425.200789", 42.80
"pkt_pts_time": "61428.480789", 46.08
"pkt_pts_time": "61431.160789", 48.76
"pkt_pts_time": "61441.240789", 58.84
"pkt_pts_time": "61445.480789", 63.08
"pkt_pts_time": "61449.600789", 67.20
"pkt_pts_time": "61456.120789", 73.72

Clearly not a NextPVR issue. Maybe there is a way to tell your tv not to choose an auto frame rate?

Well that seems pretty conclusive Martin. So, the blackouts occur where the transmission changes between progressive and interlace?
I'm just running the remux now but, as you say, it is a slow process ~1.2 x realtime.

I presume there is no way to make NextPVR record in a single framerate?

NextPVR always just records an exact copy of whatever your broadcaster sent.

I looked through the ffprobe docs but couldn't find how to reproduce that output. Could you advise please?

That remux works fine - no blackouts. Like you say though, really slow.

Actually this was more than a remux. This was re-encoding the video (to make it the same format all the way through).

This action is particularly hard on CPUs, which is one of the reasons NextPVR records the native broadcast format, which it is much easier on the CPU.

The native format is usually absolutely fine, since ultimately that's what the broadcaster wanted your TV to display, but for whatever reason it sounds like the players you're using on your TVs don't like the stream your broadcaster is producing.

Some of it was manual searching and the math but this should get you started

ffprobe -v quiet -print_format json -show_entries "frame=pkt_pts_time,interlaced_frame" -i "TEST TS.ts"

OK, right, no wonder I couldn't find it in the docs. Thanks again I really appreciate the help.

I know this is an old post, but I have been able to record in a different container other than .ts with ffmpeg and NextPVR v.4 on Win 10
with NextPVR client enabled I use ffmpeg -i  http://localhost:8866/live?channel=the channel you wish to record -c copy file.mp4 or file.mkv whatever you wish.
you can use all the filters or tweeks of ffmpeg to do whatever you wish. If the computer is powerfull enough you might be able to pipe the results to ffplay to see what is being recorded.
Personally, I mostly just use ffplay and this script to get a full screen in NextPVR and a second full screen to watch two games at once.
I hope this could help
