#64 closed defect (fixed)

Crash when change resolution

Description

Using latest version from GIT I try to decode H.264 file and FFmpeg crashes every time. The file contains several frames with ~900x700 resolution and one frame 1920x1080 (which does not to contradict to H.264 specification).

Some time ago there was similar issue (issue2393 in old tracker) and it was successfully fixed. The bug was introduced again after git revision aecd0a4 (probably with ffmpeg-mt merge). If it is required I'll find the exact revision when the bug was introduced.

Platform is WIN32.

The command line is:
ffmpeg -i all_filese_together.264 -f null out.raw

Input file and FFmpeg information:
