Video compression has been developed since the 2002 in France Telecom spin off called Envivio.
At that moment the most attractive video compression algorithm was considered to be video codec H.264 including both video compression and audio codecs parts.
This company was the pioneer in France in the field of video compression. For its solution the research results and cooperation with France Telecom have been widely used.
Technical realization of project.
The following features have been developed in the project:
- H.264 video codec implementation in C/C++
- Optimization of video codec under DSP TI target: video and audio parts (unrollment of cycles, parallelization, etc)
- encoder development(C++, COM objects)
- MPEG4 implementation
- Video card development
My participation in project:
I’ve carried ou the following tasks:
- Optimization of H.264 video codec under DSP TI target: video parts (unrollment of cycles, parallelization, etc)
- encoder development (C++, COM objects)
- Encoder features development: cropping, resizing, etc
Environment and techniques used in project:
Environment: TI DSP, assembly, C, profilng, Code Composer Studio, COM objects, C++, Sony Vegas Pro Studio
Techniques : profiling, MIPS optimization, transformation some code C to assembly
Main results:
- MIPS performance improvement in 3..8 tims for some functions in assembly
- Realisation of different encoder functions in C++/COM
- Video clips production
