From e0f5d6ae76423ec5b6f97c7c3e1f02187b988afd Mon Sep 17 00:00:00 2001 From: Benjamin Gaignard Date: Tue, 24 Jun 2025 14:29:38 +0200 Subject: [PATCH] media: verisilicon: Export only needed pixels formats Some pixel formats can only be produced if the decoder outputs reference pictures directly. In some cases, such as AV1 film-grain, the use of the post-processor is strictly required. In this case, only enumerate the post-processor supported formats. The exception is when V4L2_FMTDESC_FLAG_ENUM_ALL is set, in this case, we enumerate everything regardless of the state.
