Bug Report The broken picture in case of record, why?

[santer]

Hello,
I record video, in case of reproduction there are broken frames.
In write time there is no message that the encoder is overloaded.

Additional tests and a log are necessary?

You should always include logs if you're having a problem

I applied a log in the first post

No overloading, but broken frames...
┃ ┣download_frame: min=0 ms, median=0.001 ms, max=12.182 ms, 99th percentile=0.003 ms

What do you think about it?

You are overtuning the Quicksync encoder. LA_ICQ is tricky and not the most stable, and quality 1 is very unusual. Use ICQ rate control instead and use quality of 15..20. Smaller values than 15 only produce enormously huge files but not visibly better footage, and they strain the encoder very much.

As alternative, try NVENC as encoder. If you require it, NVENC has an explicitly lossless mode. At least with Pascal GPUs, I don't know if your slightly older GPU supports this.

NVENC lossless log, and No overloading, but broken frames...
And ┃ ┣download_frame: .... - best in quick sync
