stream parsing decide keyframedist based on samples from remote encoder

watching recording:

initial fill from db
incremental from remote encoder, until it finishes recording
then db again (which should be the final time)
stream parsing decide keyframedist based on which table in db

watching prerecorded:

initial fill from db is all that's needed

◆ GetBestVideoFormat()

AVPixelFormat DecoderBase::GetBestVideoFormat	(	AVPixelFormat *	Formats,

static

Find a suitable frame format that is mutually acceptable to the decoder and render device.

Note: Most hardware decoders will only provide one software frame format.; Currently only the OpenGL renderer supports anything other than FMT_YV12/AV_PIX_FMT_YUV420P

◆ AutoSelectTrack()

int DecoderBase::AutoSelectTrack ( uint Type )

protectedvirtual

Select best track.

In case there's only one track available, always choose it.

If there is a user selected track we try to find it.

If we can't find the user selected track we try to picked according to the ISO639Language[0..] settings.

In case there are no ISOLanguage[0..] settings, or no preferred language is found, the first found track stream is chosen

Returns: track if a track was selected, -1 otherwise

◆ DoFastForwardSeek()

void DecoderBase::DoFastForwardSeek	(	long long	desiredFrame,

	)

protectedvirtual

Seeks to the keyframe just before the desiredFrame if exact seeks is enabled, or the frame just after it if exact seeks is not enabled.

The seek is not made if framesPlayed is greater than the keyframe this would jump too. This means that frame-by-frame seeking after a keyframe must be done elsewhere.

If the seek is made the needflush parameter is set.
