libde265 is an open source implementation of the H.265 (HEVC) video codec written from scratch in C++ with a plain C API for easy integration. It supports WPP and tile-based multithreading, SSE optimizations, and includes example programs dec265 and sherlock265.
Use cases
- decode h.265/hevc video streams in my application
- integrate an HEVC decoder into a media player via a C API
- play raw h.265 bitstream files
- visually inspect h.265 bitstream structures like CU trees and intra prediction modes
- decode 4K HEVC video with multithreaded performance
- add HEVC decoding to a GStreamer pipeline
When to choose
- you need an open-source HEVC decoder with a simple C API
- you need high-performance multithreaded decoding of Main profile streams
- you want to embed HEVC decoding in C/C++ software without heavy dependencies
- you need to debug or visualize h.265 bitstream internals
When to avoid
- you need HEVC encoding rather than decoding
- you need a full-featured video player or transcoding framework
- you need profiles or features beyond the Main profile
- you prefer a hardware-accelerated decoder over a software implementation
