In many use-cases, you want them to be frame-accurate. Final rendition to the viewer is only one use-case of FFmpeg (to be fair, the likely use-case of QSV) And you don't want errors accumulating across encode cycles. > Do you have an idea where/how I could find such stream? > You would need to record them off various television services as they use a wide range of encoder manufacturers. Ideally, you could also inject them into various encoders and force them to build complex reordering patterns and check they are frame accurate.
