[FFmpeg-devel] AAC-HE problem

Thanks guys. I installed the latest version of MinGW/MySys and rebuilt my source, without any special changes to the environment, and it worked perfectly. The variable is now aligned properly and I no longer get the crash.

Thanks again,

P.S. I have made a few minor changes to the source which might be of interest to the project. How would I go about submitting those?

Basically I have two. I fixed a small bug in the MP4 muxer that was causing an issue with some files. And I modified the h264_annexb filter so that it applies the sps/pps header to I frames as well as IDR frames. This was needed because in our product we see a lot of files coming out of Europe that do not use IDR frames at all (they use I frames with SEI entry points instead) and we need an annexb header to open the files properly
