Compiling ffmpeg with some extra options sounds like an interesting track to work around the h263 crash problem.
However, with the recent ffmpeg opal 3.6.8 refuses to build H263/H263-1998 and H264. This is some output from the 
configure run:

checking for LIBAVCODEC... yes
configure: libavcodec stack align hack disabled

I installed a really recent version of libavcodec, 0.6.201102261447git from packman. Any idea what's going wrong?

ffmpeg -codecs delivers following output about the interestin codecs:
 DEV D  h261            H.261
 DEVSDT h263            H.263 / H.263-1996
 D VSD  h263i           Intel H.263
  EV    h263p           H.263+ / H.263-1998 / H.263 version 2
 D V D  h264            H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
 D V D  h264_vdpau      H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10 (VDPAU acceleration)
so they basically seem to be supported.
