Member Function Documentation

height()

int gnash::media::gst::VideoDecoderGst::height ( ) const

virtual

Get the height of the video.

Returns

The height of the video in pixels or 0 if unknown.

Implements gnash::media::VideoDecoder.

peek()

bool gnash::media::gst::VideoDecoderGst::peek ( )

virtual

Check whether a decoded frame is ready to be popped.

This method will never block.

Returns

true if there is a frame ready to be popped.

Implements gnash::media::VideoDecoder.

References SwfdecGstDecoder::queue.

pop()

std::unique_ptr< image::GnashImage > gnash::media::gst::VideoDecoderGst::pop ( )

virtual

Pop a decoded frame from the decoder. THIS METHOD MAY BLOCK.

Returns

The decoded video frame, or a NULL-containing unique_ptr if an error occurred.

Implements gnash::media::VideoDecoder.

References swfdec_gst_decoder_pull().

push()

void gnash::media::gst::VideoDecoderGst::push ( const EncodedVideoFrame &  buffer )

virtual

Push an encoded video frame into the decoder.

Parameters

buffer

the video frame to decode

Implements gnash::media::VideoDecoder.

width()

int gnash::media::gst::VideoDecoderGst::width ( ) const

virtual

Get the width of the video.

Returns

The width of the video in pixels or 0 if unknown.

Implements gnash::media::VideoDecoder.
