Hope you are doing well.

Hi,

I used DiviSuite 20.4 for analyzing the stream. ETR290 (Priority 1 and Priority) is clean.

What kind of errors do you see?

Please take a look at my config file as I am getting video source from Decklink SDI in SD (PAL) and upscaled to HD (1080i50).

I just discovered that when not using scale filter all errors gone and it is working fine with SD PAL output.

Hi, In the screenshot above, I don't see any flow related issues, just a loss of TS sync which is usually when packet loss. You are sure that the stream does not packet lost. What is the number of CC errors? How loaded is the CPU on your transcoder?

or You could try to find a stable operation in the ffmpeg, after which I will make changes to the code

Can you provide me the json config example to generate HD video using scale filter as I am working with PAL source need to convert into HD.
