Subject: [FFmpeg-devel] [PATCH 2/2] avformat/imfdec: inherit opaque from parent AVFormatContext
Date: Sat, 17 May 2025 05:50:29 +0200
Message-ID: <20250517035029.202-2-kasper93@gmail.com> (raw)
In-Reply-To: <20250517035029.202-1-kasper93@gmail.com>

io_open and io_close2 callbacks may use opaque pointer stored in the
context. They are already inherited, so opaque should also be passed
through.

Fixes IMF playback in mpv.
