2012-01-22rtpdec: Use our own SSRC in the SDES field when sending RRsMartin Storsjö
The s->ssrc field is the sender's SSRC, we use ssrc + 1 to get a collision free "unique" SSRC for ourselves in the RR part. The SDES block in the RTCP packet should describe ourselves, not the sender. This was fixed for the RR part in 952139a3226b, but wasn't fixed for the SDES part until now. This could cause some Axis cameras to send RTCP BYE packets to us due to the SSRC collision. Signed-off-by: Martin Storsjö <martin@martin.st>
2011-11-30rtpdec: Add support for G726 audioMiroslav Slugeň
This requires using a separate init function, since there isn't necessarily any fmtp lines for this codec, so parse_sdp_a_line won't be called. Incorporating it with the alloc function wouldn't do either, since it is called before the full rtpmap line is parsed (where the sample rate is extracted).

2011-11-18rtpdec: only use RTCP for PTS when synchronizing multiple streamsJohn Brooks
RTCP timestamps are only necessary to synchronize time between multiple streams. For a single stream, the RTP packet timestamp provides more reliable timing. As a result, single-stream RTP sessions should now have accurate and monotonic PTS. Signed-off-by: Martin Storsjö <martin@martin.st>

2011-11-06Replace all usage of strcasecmp/strncasecmpReimar Döffinger
All current usages of it are incompatible with localization. For example strcasecmp("i", "I") != 0 is possible, but would break many of the places where it is used. Instead use our own implementations that always treat the data as ASCII. Signed-off-by: Martin Storsjö <martin@martin.st>

2011-10-12rtpdec: Read the packet length for all RTCP packet typesJohn Brooks
This allows skipping past unsupported RTCP packet types, as RFC 3550 section 6.1 mandates. Currently this only has any practical effect if a sender puts an unrecognized type before RTCP_BYE in a compounded packet, or (incorrectly) does not put RTCP_SR first.

We actually read 20 bytes of these packets. Signed-off-by: Martin Storsjö <martin@martin.st>

2011-05-12configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS.Diego Biurrun
Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.

2011-01-06rtpdec: Don't set RTP timestamps if they already are set by the depacketizerMartin Storsjö
For MS-RTSP, we don't always get RTCP packets (never?), so the earlier timestamping code never wrote anything into pkt->pts. The rtpdec_asf depacketizer just sets the dts of the packet, so if the generic RTP timestamping is used, too, we get inconsistent timestamps. Therefore, skip the generic RTP timestamp algorithm if the depacketizer already has set something. This fixes "Invalid timestamps" warnings, present since SVN rev 26187. Originally committed as revision 26241 to svn://svn.ffmpeg.org/ffmpeg/trunk
2011-01-02rtpdec: Emit timestamps for packets before the first RTCP packet, tooMartin Storsjö
Emitted timestamps in each stream start from 0, for the first received RTP packet. Once an RTCP packet is received, that one is used for sync, emitting timestamps that fit seamlessly into the earlier ones. Originally committed as revision 26187 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-12-16rtsp: Don't set the RTP time base from the sample rate if no sample rate is setMartin Storsjö
This also reverts SVN rev 26016, which incorrectly overwrote the time base with 90 kHz for all streams, regardless of what was set by the SDP parsing. The stream that triggered the fix in 26016 still works after this commit. Originally committed as revision 26022 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-12-15Reinstate default time_base for rtp streamsLuca Barbato
The generic default is 0/0 and that obviously triggers once the value is used. Originally committed as revision 26016 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-12-07rtsp/rtpdec: Set the AVStream time_base directly in rtsp when it is knownMartin Storsjö
This fixes cases where the RTP time base and the sample rate of the stream differ. Previously, the AVStream time_base was unconditionally set to the sample rate (which initially was set to one value when parsing the rtpmap field in the SDP, but later overridden by an a=SampleRate field). Additionally, this makes the code actually use the stream time base set in rtpmap for video codecs, instead of hardcoding it to always be 90 kHz. Originally committed as revision 25908 to svn://svn.ffmpeg.org/ffmpeg/trunk

2010-10-16rtpdec: Return AVERROR(EAGAIN) for mpegts parsing errorsMartin Storsjö
This indicates that there was no error that needs to be reported to the caller, so we can move on to parse the next packet immediately, if available. The only error code that ff_mpegts_parse_packet can return indicates that there was no packet to return from the provided data, for which it returns -1.
