+Subject: [PATCH 1/5] cap_ffmpeg: drop support for very old libav* versions
+
+All relevant distros now ship the equivalent of Libav 0.8 or newer, so
+drop support for everything older as it is a maintenance burden.
+

+Subject: [PATCH 4/5] cap_ffmpeg: do not use AVStream.r_frame_rate
+
+r_frame_rate is a guessed number defined as "the least common multiple
+of all framerates in the stream". It has been deprecated and removed in
+new Libav releases.
+
+Use avg_frame_rate instead, which is the average framerate of the
+stream.
+
+(cherry picked from commit 0c8faf17694baaf62ad120b6b3103b5d022e04ed)
