Detailed Description

Abstract decoder implementation (factory).

A VideoDecoderFactory is a factory that advertises which codecs it can decode, whether it is usable on the current system, and creates decoder instances.

Member Function Documentation

IsAvailable()

virtual bool ifm3d::rtsp::VideoDecoderFactory::IsAvailable ( ) const

pure virtual

Whether this implementation can actually be used on the current system.

Implementations that depend on optional runtime libraries (e.g. the ffmpeg decoder needs libavcodec) return false when those are missing.

Name()

virtual std::string ifm3d::rtsp::VideoDecoderFactory::Name ( ) const

pure virtual

Stable, human-readable name (e.g.

"ffmpeg", "null").
