[Ffmpeg-devel] [PATCH] Fix infinite loop when decoding asf/wma packet

[Patrice Bensoussan]

Well, it seems that when the first byte is not 0x82, we continue to  
decode the packet although I don't know what the implications are for  
decoding... According to the doc below, most packets are using v82  
header. So I guess we should do something else when it's not 82...  
but it's better to do nothing than actually doing something wrong.

The file showing the issue is definitely decoded with this fix. Do  
you have any ftp I can use to upload the file? (it's about 12mb).
