ffmpeg 0.30 crashes on SMK input (0.29 runs fine)

[timfelgentreff]

According to this bug report (https://github.com/Wargus/wargus/issues/163), ffmpeg 0.30 segfaults when converting smk video/audio files. 0.29 did not have this problem.

[Marty Plummer (ntzrmtthihu777)]

Also affects me in the same manner, arch linux and ffmpeg2theora 0.30

[Karl Palsson (ubuntu-tweak)]

Affects me on fedora 23, with master, 0.30-1-ga54a035 0.30 wouldn't build (libm not linked)
0.29 doesn't build either: src/ffmpeg2theora.c:1071:40: error: 'AVCODEC_MAX_AUDIO_FRAME_SIZE' undeclared (first use in this function)) nor would 0.29

Both master and patched 0.30 have the following bt. Input test video is a raw file from a canon 500d. ffmpeg2theora --info at the bottom...
