[FFmpeg-devel] [PATCH 04/11] avformat/apngdec: Return error when header incomplete

[Andreas Rheinhardt]

When an incomplete header is encountered, apng_read_header would under
certain circumstances only return the return value of the last
successfull call. So override this by returning AVERROR_EOF manually.
