Hi
It gives the same problem. Actually my code compiles properly in a previous
version of ffmpeg but gives problem in this version. The problem is not with
coding as is clear below. There is some bug in the SVN version I downloaded.
I tried this command:
g++ -Wall -Wconversion -g -fPIC api-example.c -o api-example -lavformat
-lavcodec -lavutil -lswscale -lz -lbz2 -lm
This is what I get:
In file included from /usr/local/include/libavutil/avutil.h:81,
from /usr/local/include/libavcodec/avcodec.h:30,
from api-example.c:38:
