[FFmpeg-devel] [PATCH 1/2] dvdsubdec: reset buffer size on invalid over-large packets

[wm4]

Otherwise it will never be reset, and remain "stuck" in this state
forever. Can happen when seeking: the decoder will receive fragments
from different file positions, which triggers the condition easily.

These patches basically fix seeking.
