[FFmpeg-devel] [PATCH]lavc/h264dec: Improve "Increasing reorder buffer" message loglevel

[Carl Eugen Hoyos]

Hi!

Currently "Increasing reorder buffer" - that is important if the buffer is 
increased mid-stream - is always shown, the patch tries to improve this.

Please comment, Carl Eugen

Subject: [PATCH] lavc/h264dec: Improve "Increasing reorder buffer" message
 loglevel.

Do not show the message for the first frame by default, show a
warning if increasing is necessary in the middle of the stream.
