[x264-devel] How to display encoding time for every frame?

[Xue Victor]

Seems a rather silly question, hacked a few lines and seems to be worked.
Put a quick note on this, I am not sure whether it is correct but it at
least works..

steps:
include time.h file in x264.c,
down scrolling till Encode function, declear a struct timeval as start_t and
end_t(struct timeval start_t, end_t;),
also initial three variables to record the time(long seconds, useconds,
fr_time;).
down scrolling till see the loop with a comment saying /*Encode Frames*/,
look into the loop and find i_frame_size = Encode_frame( h, opt->hout,
&pic);
add two lines, one in front of them, the other right after this line, like
the following:
gettimeofday(&start_t, NULL);
i_frame_size = Encode_frame( h, opt->hout, &pic );
gettimeofday(&end_t, NULL);

time are calculated as follows:
seconds = end_t.tv_sec - start_t.tv_sec;
useconds = end_t.tv_usec - start_t.tv_usec;
fr_time = ((seconds)*1000 + useconds/1000.0) + 0.5;

use the same lines in the /* Flush delayed frames */ while loop.

Best,
Yuanyi
