Capture timestamps in frames and rtp packets #544

Closed baranovmv closed 10 months ago

baranovmv commented 10 months ago

Add unit timestamp fileds in nanoseconds to audio::Frame and packet::RTP.

Following components were modified to forward timestamps:

ChannelMapperReader
ChannelMapperWriter
Depacketizer
Packetizer
ResamplerReader
ResamplerWriter

Added CaptureTsFiller class (packet reader) that gets a pair of a unix timestamp and a correspondent rtp timestamp and fills capture_timestamp field in rtp packet.

Summary from matrix:

[x] add sender counterpart for CaptureTsFiller
[x] add pipeline::ReceiverStats (maybe to roc_pipeline/stats.h) with end_to_end_latency and local_latency
[x] add pipeline::ReceiverSession::stats()
[x] implement pipeline::ReceiverSource::latency() to return same value as local_latency in stats
