Subject: [FFmpeg-devel] [PATCH v2 05/10] lavc: add generic-encode-layer private data
Date: Mon,  3 Jul 2023 21:32:24 +0200
Message-ID: <20230703193229.8593-6-anton@khirnov.net> (raw)
In-Reply-To: <20230703193229.8593-1-anton@khirnov.net>

Move AVCodecInternal.intra_only_flag to it, should should not be visible
outside of encode.c.
