As our internal fork became increasingly outdated, we collaborated with FFmpeg developers, FFlabs, and VideoLAN to develop features in FFmpeg that allowed us to fully deprecate our internal fork and rely exclusively on the upstream version for our use cases. Using upstreamed patches and refactorings we’ve been able to fill two important gaps that we had previously relied on our internal fork to fill: threaded, multi-lane transcoding and real-time quality metrics.
