Hi @puligclone , Could you try SVT-HEVC ffmpeg plugin directly? https://github.com/OpenVisualCloud/SVT-HEVC/tree/master/ffmpeg_plugin

no issues with ffmpeg plugin. but it has fewer options and cant pass hdr parameters like cll and master display.

Glad to know no A/V sync issue with plugin. Yes, the plugin doesn't expose all the interfaces.
