 The base class for platform-specific implementations of TextureConverter One of two virtual methods, createTextures and createTextureHandles, must be overridden. If the implementation operates with QRhiTexture under the hood, overriding of createTextures is prefferable, otherwise expose texture handles of native textures by createTextureHandles. More...
class  TextureConverter
 The TextureConverter class implements conversion of AVFrame hw textures to textures for rendering by the specified QRhi. Any instance of TextureConverter matches the pair of FFmpeg hw frames context + QRhi. More...

◆ adjustFrameTimeBase()

AVRational QFFmpeg::adjustFrameTimeBase ( QSpan< const AVRational > supportedRates,

adjustFrameTimeBase gets adjusted timebase by a list of supported frame rates and an already adjusted frame rate.

Timebase is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented. For fixed-fps content (non-null supportedRates), timebase should be 1/framerate.

For more information, see AVStream::time_base and AVCodecContext::time_base.

The adjusted time base is supposed to be set to stream and codec context.
