C API for Video Generation

[sgonorov]

Context

The Text2VideoPipeline C++ class (src/cpp/include/openvino/genai/video_generation/text2video_pipeline.hpp) currently has no C API bindings. Other pipelines like LLMPipeline already have a working C API — the goal is to follow the same pattern and expose video generation functionality through a C interface.

What to do:

• Add a new header src/c/include/openvino/genai/c/text2video_pipeline.h following the conventions in src/c/include/openvino/genai/c/llm_pipeline.h
• Implement the C wrapper in src/c/src/ — see src/c/src/llm_pipeline.cpp for reference
• Expose at minimum: pipeline creation/destruction, generate(), and config get/set
• Add a sample under samples/c/ similar to existing C samples in samples/c/text_generation/
• Add corresponding tests

Hi @sgonorov

I’d like to take this up. I’ve reviewed the existing llm_pipeline C API bindings and can follow the same pattern to expose Text2VideoPipeline via C (header, wrapper, sample, and tests).

Please assign this issue to me if it’s still available. Thanks!

Hi @vhhoang2003, thanks for the interest! Just a heads-up that I am currently assigned to this issue and have already submitted the implementation PR for it (#3331), which is currently under review by the team. You might want to check out the other good first issues for your prerequisite task. Best of luck with your GSoC application!
