ffmpeg | branch: master | Andreas Rheinhardt <andreas.rheinhardt at gmail.com> | Thu Mar 18 19:11:40 2021 +0100| [3750390edee4b5b205de09d5539f9f881f80511e] | committer: Andreas Rheinhardt

avformat/asfdec_f: Avoid stack packet

Replace it by using AVFormatInternal.parse_pkt which is otherwise unused
when reading a header.
