The current version is r10e, is there a reason 
you are compiling with an old version?

 PIBUILD appears to be undefined.  CCPREFIX appears to be

 to check your environment or just type out the values.

I'd like to add that it is much better imo not to 
use these variables but just pass a valid --cross-prefix.

Re: [FFmpeg-user] incorrect fps and tbr

 Obviously, the fps and tbr are still wrong, 

Why do you think so?

 I posted the file  here: http://pan.baidu.com/s/1eQIY63o

This file contains 43044 frames and is a little over 43 
seconds long.
That makes 1000fps afaict...

 I may be on the wrong track here, but it sounds a 
 bit like my experience with Windows Media, i.e. 
 WMV files: The container says 1000 fps, because 
 the format is inheritantly (?) vfr.

That is (at least to some degree) correct for asf  
but the file in question is avi which is inherently 
cfr.
(At least for the given file.)

Please test the following:
$ ffmpeg -i /dev/video0 out.avi

 Moreover with alsa, this command was working few 
 months ago and not working now :

Then please run git bisect to find the change 
introducing the issue.

[FFmpeg-user] how to build ffmpeg in armv8a phone?

2015-07-19 Thread wqmffmpeg 
Dear all
how to build ffmpeg in armv8a phone?
I want to optimize ffmpeg decoder in armv8a, this will improve docoder 
efficiency
Another question, when optimized ffmpeg source code with armv7a run on armv8a 
phone, decoder efficiency is same?
