[PATCH] choose ME method in MEncoder

Hi there,
Here's a small patch for MEncoder that adds the option "me" that allows
the selection of dia (=1), hex (=2) and full(=3) ME search.
Please comment, review and consider for inclusion.

Regards,
Guillaume

While I'm at it, is there any reason why x264's CLI "--merange"
(Maximum motion vector search range) hasn't been ported to MEncoder
too?

I can add it needed...

What format do you use for streaming?  What player?  There's been talk
on the VLC lists recently about playing H.264 over RTP.  You might
want to check the archives, in case it applies to you.

No, the archive of "vlc-devel".  It think there may be something
relevant there.  Look the thread starting at
http://www.via.ecp.fr/via/ml/vlc-devel/2005-04/msg00235.html

Weighted Prediction?; Which profiles supported?

Can anyone briefly describe which 264 profiles are supported by the 
current x264? Also, is Main Profile / weighted prediction not currently 
implemented? I've done some test encodes where fade-type fluctuations 
caused by camera iris, don't seem to compress very well - I'm assuming 
this is because my test encode doesn't have weighted prediction in it?

Thanks,
Ken

HIgh profile

Hi

Is there any work or plan to include support for the FRExt High profile
in x264?

best regards

question regarding mb prediction support

Hello,

I'm a master's student interested in using your h.264 motion model
implementation as part of my research. I have been studying your code
for some time now and would like to say that you are all doing an
impressive job!

I have been looking at the functions x264_slicetype_analyse(),
x264_slicetype_frame_cost(), and x264_slicetype_mb_cost(). I was
wondering if someone could please confirm my understanding for me:

- a slice consists of one frame
- that the encoder currently uses the same MB mode for all MBs in a given frame
- sub-MB modes and 16x8, 8x16, etc... are all to be implemented 

Thank you for your time.
