I realised although I was linking my own lib files, I was still using the dlls provided by zeranoe. When I replaced these, my application now works
-----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Matthew Einhorn Sent: 26 July 2011 20:55 To: This list is about using libavcodec, libavformat, libavutil, libavdevice and libavfilter. Subject: Re: [Libav-user] Documentation FYI, you're more likely to get help from the zeranoe user forum on his website because this problem isn't likely ffmpeg related but related to the dll that zeranoe builds or your use thereof. Note, I'm using the same dlls with the same git number and I can call the av_get_pix_fmt_name function without any issues. Also, you should include your example code, otherwise it's hard to know what's going wrong.
