Hi,
Thanks for your response.

I have now checked out the latest SVN and compiled my program again and
I get the same warning. Checking avcodec.h the warnings indeed make
sense (note that I am compiling with -Wall):
2316: typedef struct ImgReSampleContext ImgReSampleContext
attribute_deprecated;
2337: attribute_deprecated void img_resample(struct
ImgReSampleContext *s, ...
Additionally, after checking out the latest svn I get this error when
compiling my application:
avcodec.h:2933: error: ‘av_malloc_attrib’ does not name a type
I don't know why this error suddenly popped up, but av_malloc_attrib
wasn't being used anywhere so I commented the line and the application
compiled (still with warnings).
I tried running the application and I get the same output i.e. wmv2
decoding errors every second or so. Oh, I think I forgot to mention that
video is streaming and playing just fine, but will suddenly get
distorted frames now and then.
So, I'm a bit confused. I am using the most recent checkout yet I'm
getting warnings that you don't see. And again, if I compile with system
headers (i.e. #include <ffmpeg/avcodec.h> instead of my own #include
"libav/avcodec.h", etc) my application gets no warnings and output shows
no wmv2 errors.
> This is not surprising: system headers have nothing to do with libavcodec...
What do you mean? By system headers I mean the ffmpeg headers that are located
in /usr/include/ffmpeg/.

1) Done
2) How would I do that? ffmpeg seems to compile and run just fine.

I agree :) I tried removing them and everything fails. As video decodes
perfectly with the same extradata and system headers, I wouldn't think
they could be the problem..?
Does anyone know more about extradata, particularly with wmv2?
Thanks,
Ola
