Subject: [PATCH 13/13] add public version of ff_read_frame_flush
We need this since we sometimes seek on the
input stream behind ffmpeg's back. After this
all data need to be flushed completely.

[ffmpeg] Speed up wtv index creation
The index creation is O(N^2) with number of entries (typically thousands).
On a Pi this can take more than 60 seconds to execute for a recording of a few hours.
By replacing with an O(N) loop, this takes virtually zero time
