Subject: [FFmpeg-devel] [PATCH 2/5] fftools/ffmpeg_filter: provide hwctx when probing graph
Date: Fri,  9 Feb 2024 15:53:46 +0100
Message-ID: <20240209145349.104511-2-ffmpeg@haasn.xyz> (raw)
In-Reply-To: <20240209145349.104511-1-ffmpeg@haasn.xyz>

From: Niklas Haas <git@haasn.dev>

Otherwise, filters that depend on a hw_device_ctx being present at
init() time would fail configuring under the semantics outlined in the
previous commit.
