-## 1. Core Directives for AI Assistant
-
-> **IMPORTANT:** These are the most critical rules. Follow them strictly.
-
-1.  **Memory Management is Paramount:**
-    - **ALWAYS** use `Handle(ClassName)` for any class inheriting from `Standard_Transient` (e.g., `Geom_*`, `Poly_*`, `AIS_*`, `V3d_*`). This is for reference-counted objects.
-    - **NEVER** use raw pointers (`ClassName*`) for these types, as it will cause memory leaks.
-    - **Correct:** `Handle(Geom_Circle) aCircle = new Geom_Circle(...);`
-    - **Wrong:** `Geom_Circle* aCircle = new Geom_Circle(...);`
-
-2.  **Check Operation Status:**
-    - After using an API that performs a geometric operation (e.g., `BRepAlgoAPI_Fuse`, `BRepBuilderAPI_MakeEdge`), **ALWAYS** check if the operation was successful using the `IsDone()` method before accessing the result.
-    - **Correct:**
-      ```cpp
-      BRepAlgoAPI_Fuse aFuser(theShape1, theShape2);
-      if (aFuser.IsDone()) {
-          auto aResult = aFuser.Shape();
-      } else {
-          // Handle error
-      }
-      ```
-
-3.  **Strict Naming and File Conventions:**
-    - Adhere to the strict `Package_ClassName` convention.
-    - Place new files in the correct directory: `src/Module/Toolkit/Package/`.
-    - After adding a file, **ALWAYS** update the corresponding `src/Module/Toolkit/FILES.cmake` file.
-
-4.  **Use Modern C++ Idioms:**
-    - Prefer `auto` for variable declarations where the type is clear, especially with iterators.
-    - Use range-based `for` loops and structured bindings where applicable.
-    - Use the modern `TopExp_Explorer` constructor style.
-    - **Correct:** `for (TopExp_Explorer anExp(theShape, TopAbs_FACE); anExp.More(); anExp.Next()) { ... }`
-    - **Wrong:** `for (TopExp_Explorer anExp; anExp.Init(theShape, TopAbs_FACE); anExp.More(); anExp.Next()) { ... }`
-
-5.  **Safe Type Casting:**
-    - When downcasting topological shapes, **ALWAYS** use the `TopoDS` helper functions to avoid errors.
-    - **Correct:** `auto aFace = TopoDS::Face(anExp.Current());`
-    - **Wrong:** `auto aFace = (const TopoDS_Face&)anExp.Current();`
-
-6.  **Handle Downcasting:**
-    - Use `Handle(DerivedClass)::DownCast(BaseHandle)` to safely downcast handles.
-    - **Correct:**
-      ```cpp
-      Handle(Geom_Circle) circ = Handle(Geom_Circle)::DownCast(someCurveHandle);
-      ```
-    - **Wrong:**
-      ```cpp
-      // Do not use C-style casts on handles
-      Geom_Circle* circ = (Geom_Circle*)someHandle.Get();
-      ```
-
-7.  **Validate Handles for Null Safety:**
-    - **ALWAYS** check that a `Handle(ClassName)` is not null before dereferencing it:
-      ```cpp
-      if (!theHandle.IsNull()) {
-          // use theHandle
-      }
-      ```

-## 2. Project Overview
-
-Open CASCADE Technology (OCCT) is a comprehensive C++ software development platform for 3D surface and solid modeling, CAD data exchange, and visualization. It's a modern C++17+ library providing services for CAD/CAM/CAE applications.
-
-### Architecture & Source Organization
-
-- **`src/`**: Source code, organized by a `Module/Toolkit/Package` hierarchy.
-- **`tests/`**: Draw Harness test files, organized by functionality.
-- **`adm/`**: Administrative and build configuration files (CMake).
-- **`samples/`**: Example applications.
-

-## 3. Code Conventions
-
-### Naming Patterns
-
-| Element Type                | Pattern                      | Example                          |
-| --------------------------- | ---------------------------- | -------------------------------- |
-| **Classes**                 | `Package_ClassName`          | `TopoDS_Shape`, `BRep_Builder`   |
-| **Public Methods**          | `MethodName`                 | `IsDone()`, `Shape()`            |
-| **Private Methods**         | `methodName`                 | `myInternalMethod()`             |
-| **Method Parameters**       | `theParameterName`           | `theShape`, `theTolerance`       |
-| **Local Variables**         | `aVariableName`              | `aBox`, `anExplorer`             |
-| **Class Member Fields**     | `myFieldName`                | `myShape`, `myIsDone`            |
-| **Struct Member Fields**    | `FieldVariableName`          | `Point`, `Value`                 |
-| **Global Variables**        | `THE_GLOBAL_VARIABLE`        | `THE_DEFAULT_PRECISION`          |
-
-### Type Mappings
-
-| OCCT Type           | C++ Equivalent | Notes                               |
-| ------------------- | -------------- | ----------------------------------- |
-| `Standard_Real`     | `double`       | Use for all floating-point numbers. |
-| `Standard_Integer`  | `int`          | Use for all integer values.         |
-| `Standard_Boolean`  | `bool`         | Use for `true`/`false` values.      |
-
-### Modern C++ Encouraged
-This is a C++17+ codebase. Proactively use modern features to improve code quality:
-- `auto`
-- Range-based `for` loops
-- Structured bindings: `for (const auto& [key, value] : aMap)`
-- `std::optional` for optional return values where appropriate.
-- `if constexpr` for compile-time conditions.

-## 4. Step-by-Step Workflow Example: Adding a New Class and Test
-
-This example demonstrates the end-to-end process for adding a new class `BRepTest_MyNewClass` to the `TKTopAlgo` toolkit and creating a corresponding GTest.
-
-**1. Create Header and Source Files:**
-Navigate to the correct package directory and create the files.
-```bash
-# Navigate to the BRepTest package in the ModelingAlgorithms module
-cd src/ModelingAlgorithms/TKTopAlgo/BRepTest
-touch BRepTest_MyNewClass.hxx BRepTest_MyNewClass.cxx
-```
-
-**2. Implement the Class:**
-Add content to `BRepTest_MyNewClass.hxx` and `.cxx`, following all code conventions.
-
-**3. Add Files to CMake:**
-Edit the toolkit's `FILES.cmake` to register the new files.
-```bash
-# Edit the CMake file for TKTopAlgo
-vim src/ModelingAlgorithms/TKTopAlgo/FILES.cmake
-```
-Add the new files to the `OCCT_<PackageName>_FILES` list:
-```cmake
-# In FILES.cmake
-...
-set (OCCT_BRepTest_FILES
-    ...
-    BRepTest_MyNewClass.hxx
-    BRepTest_MyNewClass.cxx
-    ...
-)
-```
-
-**4. Create a GTest:**
-Navigate to the GTest directory for the toolkit and create a test file.
-```bash
-# Navigate to the GTest directory for TKTopAlgo
-cd src/ModelingAlgorithms/TKTopAlgo/GTests
-touch BRepTest_MyNewClass_Test.cxx
-```
-Write the test implementation in the new file.
-
-**5. Add GTest to CMake:**
-Edit the same `FILES.cmake` to add the test file.
-```cmake
-# In FILES.cmake
-...
-set (OCCT_TKTopAlgo_GTests_FILES
-    ...
-    GTests/BRepTest_MyNewClass_Test.cxx
-    ...
-)
-```
-
-**6. Build and Run Test:**
-From the `build` directory, build the project and run the tests.
-```bash
-# Navigate to build directory
-cd build
-
-# Re-run CMake to pick up new files (usually not needed, but good practice)
-cmake .. -DBUILD_GTEST=ON
-
-# Build the project
-cmake --build . --config Release
-
-# Run the tests
-./bin/OpenCascadeGTest --gtest_filter=*MyNewClass*
-```

-## 5. Build and Test System
-
-### Build System (CMake)
-- **Primary build system:** CMake 3.16+ recommended.
-- **Build Directory:** Always build in a separate directory (e.g., `build/`).
-- **Quick Build:**
-  ```bash
-  mkdir -p build && cd build
-  cmake .. -DCMAKE_BUILD_TYPE=Release -DBUILD_GTEST=ON
-  cmake --build . --config Release --parallel
-  ```
-- **Environment:** Before running any OCCT executable (including tests), you **must** source the environment script: `source build/env.sh` (or `build\env.bat` on Windows).
-
-### Testing Frameworks
-- **Draw Harness:** Tcl-based framework for interactive testing. Located in `tests/`. Run with `build/DRAWEXE`.
-- **GTest:** C++ unit testing framework. Tests are located in `src/.../GTests/`. Enable with `-DBUILD_GTEST=ON`.
-
----
-
-## 6. Common Patterns & Key Packages
-
-### Common Operations
-
-- **Shape Creation:** Use `BRepPrimAPI_` classes (`MakeBox`, `MakeCylinder`).
-- **Boolean Operations:** Use `BRepAlgoAPI_` classes (`Fuse`, `Cut`, `Common`).
-- **Shape Exploration:** Use `TopExp_Explorer`.
-- **Transformations:** Use `gp_Trsf` and `BRepBuilderAPI_Transform`.
-
-### Key Packages
-
-| Package     | Purpose                               | Module                |
-| ----------- | ------------------------------------- | --------------------- |
-| `gp`        | Geometric Primitives (Points, Vecs)   | FoundationClasses     |
-| `Geom`      | Geometric entities (Curves, Surfaces) | ModelingData          |
-| `TopoDS`    | Topological Data Structures (Shapes)  | ModelingData          |
-| `TopExp`    | Exploring topological shapes          | ModelingData          |
-| `BRepAlgoAPI` | High-level modeling algorithms      | ModelingAlgorithms    |
-| `BRepPrimAPI` | Geometric primitives creation       | ModelingAlgorithms    |
-| `AIS`       | Application Interactive Services      | Visualization         |
-
-### Common Headers
-```cpp
-#include <Standard_Failure.hxx>
-#include <Handle_Geom_Circle.hxx>
-#include <gp_Pnt.hxx>
-#include <gp_Trsf.hxx>
-#include <TopoDS.hxx>
-#include <TopoDS_Face.hxx>
-#include <TopExp_Explorer.hxx>
-#include <BRep_Builder.hxx>
-#include <BRepAlgoAPI_Fuse.hxx>
-#include <BRepBuilderAPI_Transform.hxx>
-#include <BRepPrimAPI_MakeBox.hxx>
-```

-## 7. Key Files & Platform Notes
-
-- **`adm/MODULES`**: Defines all modules and toolkits.
-- **`src/*/FILES.cmake`**: Lists all source/header files for a toolkit. **You must edit this when adding/removing files.**
-- **`build/env.sh/bat`**: The crucial environment script.

+Subject: [PATCH] lavc/h264_ps: always include the stop bit in [s|p]ps->data
+
+The VideoToolbox hwaccel needs the entire NAL (including the stop bit),
+but ff_h2645_packet_split may remove it. Detect this case by looking for
+bit counts divisible by 8 and insert a stop-bit-only 0x80 byte.
