Although applied, I tested it again using ffmpeg for transcoding the 
corepng.avi into yuv format.

This revealed a bug in my ffmpeg.c patch, but this bug breaks CorePNG 
decoding only, since this is the only one using more information of the 
provided packet than .data and .size attributes.

FFplay is not broken as it uses no local AVPackets but the "original" one.

I attached a little patch for the time being, but I would propose to add 
a "av_copy_packet" function into libavcodec/avpacket.c as future codecs 
will also use more attributes of the avpacket and even others than just 
the .flags attribute.
