Hello,
I have recently install ffmpeg version 2.3.3 from source on Redhat linux
6.5.I am getting the below error while trying to convert a .tif file to
.mp4 file using the below syntax. If I remove "-flags2 +mixed_refs" option
from the below syntax the command just works fine and produce a .mp4
file.We are using the same syntax on an older version of ffmeg running
Redhat 5.7 and the command works fine.
Is there any different option which needs to be used in place of "-flags2
+mixed_refs" in the newer version of ffmpeg?Please advise.

Codec AVOption b (set bitrate (in bits/s)) specified for output file #0
(rain-26Aug2011_0Z.mp4) has not been used for any stream. The most likely
reason is either wrong type (e.g. a video option with no video streams) or
that it is a private option of some encoder which was not actually used
for any stream.
No pixel format specified, yuv444p for H.264 encoding chosen.
Use -pix_fmt yuv420p for compatibility with outdated media players.
