Bug 128767 – xine-lib-1.1.1-r5 fails with compiler error in h263.c : mpeg4_decode_partition_a regarding unimplemented function: mpeg4_decode_dc

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Aakash 2006-04-04 06:39:36 UTC]

The same issue (except with a different rev of xine-lib - thus the new bug report) as bug 119014 occurs with xine-lib 1.1.1-r5 and the following static inlined functions: mpeg4_decode_dc and mpeg4_decode_block. It's been a really, really long time since I've written anything in C but I believe it may have to do with a change in where the compiler expects to find the definition (not declaration) of the functions. Currently, the definition of the functions are located after calls are made to them. If I move the definition of the functions up in the source code (i.e. before calls to the functions are made), the issue is resolved. 

I'll include a patch file once I remember how to create one. (PS apologies if this should have been piggy backed on bug 119014).

Well, I think this is best handled with a single bug. Looks like ffmpeg issue, not  xine-lib.
