I'm sure I'm missing something silly, but how do I set trans coding profiles?

Backin69

Hi,

So I basically just want two codec profiles. The pass one and a mobile streaming one.

I don't care if these get configured by username or whatever, just that I can set them.

I've set the pass profile and my mobile streaming profile to be the only two enabled.

I've only found two Android mobile clients that work. Sparkle and Dream Client. Neither have an option to set what codec they're using and appear to default to the pass profile.

Is there a way in TV headend to change what stream is served by user? Like can I set Tom to only be able to get the mobile stream?

After you define a user 'Tom' in Configuration > Users > Access Entries.
Any user has one setting in Advanced Settings (maybe you have to enable View level: Expert on top right side of the page): Streaming Profiles is a list of profiles that will be advertised for that client. If you want a particular profile you have to check the check box for that profile.
Alternative client (I don't use it so I can't comment how well works): rsiebert/TVHClient --> https://play.google.com/store/apps/details?id=org.tvheadend.tvhclient&hl=en_US

OK, there's more to this.

I've set Toms profile to only have access to the MobileStream format. However this still causes the full pass stream to show up on the client side. It actually says he's getting the MobileStream profile in the subscription section of TVheadend.

I removed toms HTSP access as I presumed this is what was causing this, and set his streaming settings to Basic only.

This causes the video not to load on the client...

Thanks for the reply! I see it now!
Knew I was just missing it from somewhere.
Yeah, TVHclient was one of the first I tried. It just complains it can't connect and gives no other error.

Actually, I got confused by the ports on TVHclient. I have it working now. That 9981 and 9982 difference wasn't apparent to me when I tried it yesterday.

OK, the actual stream isn't starting (got debug logs enabled now).

AVBSFContext: Codec 'mpeg2video' (2) is not supported by the bitstream filter 'h264_mp4toannexb'

Not sure what lib i'd need to install to make this work, I just switched to another .264 option and it works now!

I also stupidly had it set to only transcode certain formats and had to unselect that so it would transcode everything.

Sucking diesel now! However audio is slightly out of sync. Not sure if it's worth wrecking my head over as it's not bad.

Backin69 can you check the CPU loading (I assume you don't use HW encoding)? maybe the CPU load is too high and is generating this out of sync.

I actually have been looking at the CPU load to make sure it wasn't going to cause any issues if I added a few users. Using the "faster" preset, HTOP shows the process as using 35%. Since I've 16 threads on that machine, I believe total CPU usage goes up to 1600%, or to put it another way, the reencoding is using like 2% of the CPU.

Regardless, it's not struggling anyway 😃

Originally I had the audio set as pasthrough and just reencoded the video. That was very out of sync. Now I'm reencoding both, it's not nearly as bad. Probably a few 100 ms?
I haven't ruled out that the issue isn't on the client side either actually, but I don't believe it is.

Backin69 if you are interested on HW encoding (personally I tested with Intel) you can check the tutorial: https://docs.tvheadend.org/documentation/development/compiling/compiling-tvh-with-vaapi-support/for-lubuntu-24.04

I've no hardware encoder on that system, but the CPU churns through it easily, so not worried.
