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...

AVPacketSideData * QFFmpeg::addStreamSideData ( AVStream * stream,
AVPacketSideData sideData )

Definition at line 104 of file qffmpeg.cpp.

◆ adjustChannelLayout()

ChannelLayoutT QFFmpeg::adjustChannelLayout ( QSpan< const ChannelLayoutT > supportedLayouts,
const ChannelLayoutT & requested )

Definition at line 71 of file qffmpegaudioencoderutils.cpp.

◆ adjustFrameRate()

AVRational QFFmpeg::adjustFrameRate ( QSpan< const AVRational > supportedRates,
qreal requestedRate )

adjustFrameRate get a rational frame rate be requested qreal rate. If the codec supports fixed frame rate (non-null supportedRates), the function selects the most suitable one, otherwise just makes AVRational from qreal.

Definition at line 244 of file qffmpegvideoencoderutils.cpp.

◆ adjustFrameTimeBase()

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

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.
