How enable the WPP encoder in Vvenc

[Ivann11-Carretero]

I am performing tests with the vvenc encoder and I need for one of them to enable only the WPP technique, I am using the following sequence .\vvencFFapp.exe -c . \c ...\cfg\randomaccess_medium.cfg -c ...\cfg\randomaccess_medium.cfg -t 4 --TileParallelCtuEnc 0 --FppLinesSynchro 0 --IFPLines 0 --IFP 0 --EnablePicPartitioning 1 --WppBitEqual 1
With this sequence then the summary provided by the encoder itself comes out as disabled, i.e. it says WPP: 0

You mean WPP as in the normative WPP? For us, the default parallelization is a WPP-like, but encoder-only, concept. That is what WppBitEqual stands for (but also, its only really needed when threads is 0, otherwise its always active).

If you want the normative WPP (line-wise context propagation and reduced upper-right neighbor availability), you need to use --WaveFrontSynchro=1.

Okay, thank you.
