vaapi: Fix infinite loop in encrypted sample parsing If we ended up with a subsample that started in the middle of a block, but did not complete that block, then we'd end up with an integer overflow. The consequence of it is only that it then increments the the lower 32 bits of the IV 2^64 times (infinite loop for practical purposes). While it is an integer overflow, it doesn't create an actual security issue.

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.
The project's web site is https://www.chromium.org.
To check out the source code locally, don't use git clone! Instead, follow the instructions on how to get the code.
Documentation in the source is rooted in docs/README.md.
Learn how to Get Around the Chromium Source Code Directory Structure .
For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
