Big resolutions performance

[RavNowak]

Hello,
I'm using Broadway to live streaming. There are no problems when sending video of resolution 1366x768 - all works perfect. Problems begin when trying render 2560x1440 - big delays appear.

I'm using Player API. Worker and webgl are on.

I wonder if this is due to decoder or renderer performance.

Thanks for your answers/suggestioons.

hi!
hard to say. the rendering with webgl works on the gpu and is highly parallelized. so i would guess your performance bottleneck is in the decoding itself.

there might be ways to boost decoding with slices. let me get back to you about that

Thanks for your fast reply @soliton4 .

"there might be ways to boost decoding with slices" - seems very interesting.
Currently I'm feeding Player instance with single NALu units (one by one).

I'm curious how could this slicing process looks like.
Waiting for yours ideas, so be in touch.

Hi,
@soliton4 , could you say something more about that decoding with slices ?

i have not forgotten you, just being busy with other stuff.
i would like to know some numbers, what time difference are we talking about comparing the 2560x1440 stream with lets say a 1024x720 stream
can you measure the time it takes to decode one frame and post your measurements here please?

i need both numbers for small and high res stream to get a picture of your problem

@myjimmy and @soliton4 :
Was any conclusion reached on this issue, I think we are also observing similar issues.
