Different AV1 Decoder DLLs (Version 1.0 and 1.2.1) in XnViewMP

Post by masterjp »

Today I looked for a new AV1 decoder DLL from VideoLAN and saw, that version 1.4 is released. The AV1 decoder DLL in XnViewMP is from 2022.

I checked the version from XnViewMP and found out, that XnViewMP use 2 different AV1 decoder dLLs from VideoLAN in Version 1.0 and 1.2.1.
One of them is used by the video playback function of XnViewMP (folder XnviewMP).
The other DLL (XnviewMP - Plugin folder) should be part of the HEIF/HEIC or JPEGXL encoder.

I tried the latest DAV1D Decoder plugin DLL from VLC Player 3.2 in XnViewMP 1.7.1 and the CPU usage is smaller than the currently used version 1.x.
Maybe you want to replace the older one for better video playback performance. In the changelog of the AV1 decoder from VideoLAN I can see, that they have optimized their code for Intel CPUs with AVX extensions and other optimizations.

Thank you!
