Subject: [PATCH] chromium-93: fix building with system-ffmpeg
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The version of ffmpeg bundled in Chromium changed ABI a little, which
affected the code in that the type of the last parameter of
av_packet_get_side_data() is now size_t instead of int.

This causes Chromium to fail to build with system-ffmpeg if the system
ffmpeg's version does not yet have this ABI change.

Fix the code to be able to compile with older ffmpeg as well.
