Detailed Description

Defines a video renderer that renders frames to the given SDL window when specified by the app. The app is expected to periodically call Render to render the frame. This allows the app to draw the frames as part of their normal render loop.

Definition at line 38 of file sdl_video_renderer.h.

Constructor & Destructor Documentation

§ SdlManualVideoRenderer()

shaka::media::SdlManualVideoRenderer::SdlManualVideoRenderer ( SDL_Renderer * renderer = nullptr )

Creates a new renderer that renders using the given renderer object.

Parameters

renderer The renderer object used to create textures. If not given, apps must call SetRenderer before calling Render.

Definition at line 125 of file sdl_video_renderer.cc.

§ ~SdlManualVideoRenderer()

shaka::media::SdlManualVideoRenderer::~SdlManualVideoRenderer ( )

override

Definition at line 127 of file sdl_video_renderer.cc.

Member Function Documentation

§ Attach()

void shaka::media::SdlManualVideoRenderer::Attach ( const DecodedStream * stream )

overridevirtual

Attaches to the given stream. This object will now pull full-frames from the given stream to play content. The stream will live as long as this object, or until a call to Detach.

Parameters

stream The stream to pull frames from.

Implements shaka::media::Renderer.

Definition at line 143 of file sdl_video_renderer.cc.

§ Detach()

void shaka::media::SdlManualVideoRenderer::Detach ( )

overridevirtual

Detaches playback from the current stream. The current stream will no longer be used to play content.

Implements shaka::media::Renderer.

Definition at line 146 of file sdl_video_renderer.cc.

§ GetRenderer()

SDL_Renderer * shaka::media::SdlManualVideoRenderer::GetRenderer ( ) const

Returns: The current renderer used to draw frames.

Definition at line 132 of file sdl_video_renderer.cc.

§ Render()

double shaka::media::SdlManualVideoRenderer::Render ( const SDL_Rect * region = nullptr )

Renders the current video frame to the given sub-region of the current renderer.

Parameters

region The region to draw the video to. If not given, video will take up the entire window.

Returns: The suggested delay, in seconds, before the next call to Render; this uses the framerate and current time to suggest the next delay.

Definition at line 136 of file sdl_video_renderer.cc.

§ SetPlayer()

void shaka::media::SdlManualVideoRenderer::SetPlayer ( const MediaPlayer * player )

overridevirtual

Sets the MediaPlayer that is controlling this renderer. This will be used by the Renderer to query the current time and playback state.

Parameters

player The MediaPlayer instance controlling this object.

Implements shaka::media::Renderer.

Definition at line 140 of file sdl_video_renderer.cc.

§ SetRenderer()

void shaka::media::SdlManualVideoRenderer::SetRenderer ( SDL_Renderer * renderer )

Sets the renderer used to create textures. Changing the renderer during playback causes performance loss since internally-cached textures are invalidated. It is assumed this renderer will live as long as this object or to another call to SetRenderer.

Parameters

renderer The renderer used to create textures.
