            Bug ID: 43253
           Summary: AVI compression with builtin avifil32.dll is corrupt
           Product: Wine
           Version: 2.9
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org

TinyAVI executions with WINEDEBUG=+avifile showing the difference between the
builtin and native avifil32 library.

AVI files being compressed into TAVI files using the program TinyAVI (version
4.12) are corrupted and cannot be read by the appropriate video player
(DV_ADAS).  If the avifil32.dll is replaced with the native Windows version
(Windows 7) compression produces the same result as it does on native Windows.

Whenever Wine tries to read in AVI data it appears to be reading something in
wrong or incompletely (just a guess). No errors are thrown, but some
incriminating warnings led me to try the native avifil32 library.

Example warning:
warn:avifile:AVIFILE_LoadFile : found extra chunk 0x504C4544

These warnings do not appear in the log when running with the native avifil32
library.
