Subject: [PATCH 6/7] wavparse: Fix clipping of size to the file size
|
|
|
|
The size does not include the 8 bytes tag and length, so an additional 8 bytes
|
|
must be removed here. 8 bytes are always available at this point because
|
|
otherwise the parsing of the tag and length right above would've failed.
|
|
|
|
Thanks to Antonio Morales for finding and reporting the issue.
