[MPlayer-dev-eng] [PATCH] Problem using libavcodec.so

[Panagiotis Issaris]

Hi,

For some time now, mencoder CVS failed to link dynamically to libavcodec.so:

cc -I../libvo -I../../libvo -I/usr/X11R6/include -fno-PIC -O4
-march=pentium4 -mcpu=pentium4 -pipe -ffast-math -fomit-frame-pointer
-D_REENTRANT -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64  -I.
-I/usr/include/freetype2   -I/usr/X11R6/include    -o mencoder

libmpcodecs/libmpencoders.a(ae.o)(.text+0xb9): In function
`new_audio_encoder':
: undefined reference to `mpae_init_lavc'
collect2: ld returned 1 exit status

This seems to be caused by libmpencoders.a not containing ae_lavc.o.

The attached patch contains a fix for this.

With friendly regards,
Takis
