possible fix

This patch makes gnash build against ffmpeg-0.6.90_rc0. But I am not sure whether it is the correct solution.

your fix is correct but this function not being available indicates a bug in ffmpeg, I'll send a patch upstream for it
(at least ffmpeg-0.6 supports av_parser_parse2, didnt check older versions)

[Comment 5 Alexis Ballier 2011-04-12 14:34:08 UTC]

ah, this is already fixed in git, I'll backport it and push a -r1

[Comment 6 Chí-Thanh Christopher Nguyễn 2011-07-02 21:09:05 UTC]

In ffmpeg-0.8 this was removed for good. I added patches to gnash so it no longer uses the deprecated symbols.
