Detailed Description

An implementation of the Demuxer type that uses FFmpeg to demux frames. This produces FFmpegEncodedFrame objects.

§ Demux()

bool shaka::media::ffmpeg::FFmpegDemuxer::Demux	(	double	timestamp_offset,
		const uint8_t *	data,
		size_t	size,
		std::vector< std::shared_ptr< EncodedFrame >> *	frames
	)

overridevirtual

Attempts to demux the given data into some number of encoded frames.

If the data contains multiple streams (i.e. multiplexed content), then all frames will be given and they will be separated based on their stream_info field.

This may be given segments from a different source after starting. This will be first given the init segment for the new stream then the new segments. This should support this case and reinitialize the demxuer if needed. The resulting frames should have different stream_info fields from before, even if they are of the same type and codec.

Parameters

timestamp_offset	The current offset to add to the timestamps.
data	The data to demux.
size	The number of bytes in data.
frames	[OUT] Where to insert newly created frames.

Returns: True on success, false on error.

Implements shaka::media::Demuxer.

§ Reset()

void shaka::media::ffmpeg::FFmpegDemuxer::Reset ( )

overridevirtual

Resets the demuxer to parse a new stream. This may be called when adapting before parsing a new stream. This should reset any partial reads and should prepare to read from a new stream. This may not be called during adaptation, so the demuxer should still handle getting a new init segment without calling Reset first.
