EXPERIMENTAL: New MPEG-TS Rewriter for HLS (TVE)

History, all 3 hallmarks, tastemade, so far. Will test more later.

Update

Add
Sundance channel
AMC

I just tested with and without the experimental feature. The dropped frame count on the show stats menu slowly increases over time and follows when the experimental feature is turned on. Seen this on

History channel
AMC
Wired to fish (a m3u freebie)
Discovery

I havent see any count increase on OTA stations with the experimental feature.

In my case these dropped frames are not noticeable and i havent obseved studdering , pixalations, etc.

The count just slowly increases over time.
Im seeing the count increase to around 8 after of a minute or so depending on the channel.

btw - When I turn the show stats, whether the experimental feature is enabled or not, there are always a few dropped frames when the stats window pops up. Ive seen this before many moons ago and chalked it up to a startup condition and ignored the low count (between 2 and 4)

What i observe is that when the experimental feature is enabled, the count increase slowly over time. Does not increase when experimental feature turned off

If you watch carefully you will see a momentary hitch in picture, like a 3:2 pull-down.

@eric I'm also seeing this on a TVE recording from the history channel. Ive got the stats page up and I'll get a burst of about 3 frames dropped and a visible "hitch" in the video. Not sure if this helps but I also noticed that the audio bitrate disappears from the stats while i am dropping the frames. Weird thing is that the dropped frame counter keeps resetting itself and starting over at 0. All of this was on my iPad connected to an external display. Hope this helps.
edit: video bitrate disappears too

I think the frame counter disappears where there is a commercial skip. Or at least that was what I thought I was seeing when that happened.

Thanks for all the reports, everyone. It doesn’t look like this is ready to roll out yet. We’ll have to do more work to get it there.

This works fine for nat geo wild.
Only used for a couple hrs so far on my livingroom tv that uses a Nvidia Shield Pro.
Played History and the other channels other say have issues, plays fine for me.
Have not tried a recording yet.

Hi Eric,
I promised feedback on Tuesday... While I'm aware of the feedback that you've recently been provided on the live viewing, watching and processing recorded shows is 100% better with the new rewriter.

The recordings from Disco last night were 100% of their expected length, and were good enough quality for my normal process to cut, then re-encode. It even worked with a couple of the 4 hour recordings that I was having trouble with.

Hi, how do I get the pre release builds?

I tried it for a week or so then disabled it because my NBC TVE feed began to stutter. The audio played fine, but the video would pause briefly every few seconds making it really annoying to watch.

Yup that was the same issue I was running into. Video drops but audio played fine through it.

Is this something we should resume testing again now?

Nope, not yet.

We've published a new pre-release that contains a rewritten rewriter that is ready for testing again.

In the testing I've done, it performs much better than the last attempt in all of the scenarios I tested. Please let us know if you run into any issues.

As always, please remember this warning when enabling the experimental feature:

I will update and enable the option as soon as I get the chance.

Does this have any effect on OTA HDHomerun?

No. It says TVE/M3U in the title.

I figured that was the case but HDHR also uses MPEG-TS.

Running version 2023.02.19.2355 now and option enabled.

First recording in progress and I have more than a dozen recordings scheduled in the next 24 hours.
I will keep an eye on it and report any issues.

If you don't hear from me again, that's a good sign. :wink:
