+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.
+
