[FFmpeg-devel] [PATCH 2/2] Use av_fast_malloc instead of av_realloc. This should be faster, is less code and fixes issue 2524 (allocation error would lead to crash). (cherry picked from commit e7b95918fca1c3d057d35f77ba58ee2d00d03151)

av_fast_malloc does set it;

void av_fast_malloc(void *ptr, unsigned int *size, FF_INTERNALC_MEM_TYPE
