2009-12-20	RTP Proxy: Fix RTP sequence number and timestamp in case of dropped frames	Harald Welte	1	-0/+35
	During handover, we will not send RTP frames for quite some time. However, the way the rtp_send code is structured, it will increment the timestamp with a fixed amount every time we send a frame, independent how much wallclock time has actually passed. This code is a hack to update the sequence number and timestamp in case it seems to be wrong. It makes handover much more reliable.
2009-12-19	Add RTP support for EFR	Harald Welte	1	-0/+9
	This is just the minimal support to receive and send EFR codec RTP frames. We are missing the code to convert TRAU frames in EFR format!
2009-12-19	RTP-enable MNCC API for LCR + ip.access	Harald Welte	1	-5/+222
	Instead of passing TRAU frames down the MNCC API to the call control application like MNCC, we now decode the TRAU frame into the actual codec frame. We do the same with the RTP packets in case of ip.access and thus have a unified format of passing codec data from the BTS to an application, independent of the BTS type. This is only implemented for V1 full-rate at the moment, and needs to be fixed.
2009-12-17	logging: introduce log levels at caller site	Harald Welte	1	-1/+1
	This introduces a new LOGP() macro together with LOGL_* definition to support multiple log levels (severities) throughout the codebase. Please note that the actual logging system does not use them yet, in this patch we simply introduce the new macros at the caller site.
2009-08-10	rtp_proxy: Add two case and a DEBUG statement..	Holger Hans Peter Freyther	1	-1/+6
	Handle the case values to make the compiler happy and a runtime warning... This is similiar to other places of the code
2009-07-29	Merge commit 'origin/master'	Harald Welte	1	-1/+1

2009-07-29	fix typo when using sizeof() to determine the size of the RTCP header	Harald Welte	1	-1/+1
	This was spotted by zecke, thanks.
2009-07-29	rtp_proxy.c: Spelling fix, kook -> look	Holger Hans Peter Freyther	1	-1/+1

2009-07-28	add RTP proxy mode for ip.access	Harald Welte	1	-12/+176
	Up until now, we only supported direct RTP streams between ip.access BTS. With this commit, the user can specify '-P' to the command line to enable a RTP/RTCP proxy inside OpenBSC. The nanoBTS will then send all their voice data to OpenBSC, which will relay it to the respective destination BTS (which can be the same BTS). The default behaviour remains unchanged. Without '-P' on the command line, RTP/RTCP is exchanged directly.
2009-07-28	add new rtp_proxy code, but not use it yet	Harald Welte	1	-0/+282
	The rtp_proxy.[ch] code is intended to be used as a transparent RTP/RTCP proxy, relaying the media streams from one ip.access BTS to another. In an 'ideal' network, this is obviously not needed, since the BTS's can send those streams directly between each other. However, for debugging, 'lawful interception', transcoding or interfacing a TRAU/E1 based BTS, we actually need to process those RTP streams ourselves.
