HDMI 2nd stream not working (TBS2603)

[Alegpl]

I've tried 1.0.26 with your settings plus:
- source 1920x1080
- HDMI main same as you, with h264 and 1920x1080, 8 Mbit vbr
- HDMI 2nd h265 and 1280x720, 1 Mbit vbr
The result is impossible to use, continuous glitches and slow moving.
It's really frustrating. At the end 95% of the settings can't be used, only 1 stream and with certain parameters.

Try to reduce the main stream to 4mbps, it may help with glitches.

But there areglitches also with 1280x720 and 1 Mbit. I have to try if the problem is using h264 and h265 together or the different resolution.

[DrCool]

h265 tends to have more glitches with static images than h264, otherwise picture quality is clearly better with h265.

I tried the firmware posted on another topic (1.0.49) and the situation is much better. It is still a bit unstable (I had to reboot sometimes) but it worked with 2 streams, also h264 and 265 together.
h264 worked good also with high profile preset that I noticed it's much better with heavy streaming like sports.

Unfortunately version 1.0.49 tends to freeze frequently with my setup, and it has the same audio glitches of version 1.0.26 in my case when it works. Going back to 1.0.26.

Yes there are some glitches but I don't know, maybe it depends on the player or the source. In my case they are not so frequent and, moreover, 1.0.49 has two big advantages:
1. the video-audio sync keeps being ok not like previos firmwares (I had seconds out of sync) after some hours of streaming
2. hdmi main and 2nd work together

Problems:
1. audio glitches (pretty rare in my case but they exist)
2. crash of HDMI main after some hours while the 2nd keeps working

This is my configuration:

HDMI main
H265
frame rate 30
vbr
key 60
size auto
minQp 4
maxQp 45
bitrate 11000

HDMI 2nd
H265
frame rate 30
vbr
key 60
size auto
minQp 4
maxQp 45
bitrate 512
Audio
96000
left
AAC

I tried also main with H264 with high profile (necessary for fast sport images) and the problems are the same.

[DrCool]

Thanks. The problem may be audio 96000, I use never less than 160000, any less it's unbearable to me. I'll need to test it again to confirm, but source may also play a role, mine is 1080p from an IPTV box.

[Alegpl]

Me too 1080p

[DrCool]

OK, version 1.0.49 is the best available up to now. A few quirks however: the most stable audio stream bitrates are 96k and 160k. Other audio bitrates produce audio glitches much more frequently. In my setup any video rate above 3000k for h.265 or h.264 leads to audio glitches and sometimes to video glitches or frequent freezes. I found that at 3000k video and 160k audio I have a very watchable, quite satisfactorily 1080p experience, with few glitches and rare freezes.
