* rtpdec: Allow setting the need_parsing field in RTPDynamicProtocolHandlerMartin Storsjö2015-02-24
| | | | | | | | | | This allows getting rid of quite a bit of boilerplate in depacketizers. The default value (initializing need_parsing to 0, aka AVSTREAM_PARSE_NONE) is the same as it is initialized to by default in AVStream. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Change enc_name to a pointer instead of a fixed-size bufferMartin Storsjö2015-02-24
| | | | | | | This avoids allocating space for a too large buffer for all the name strings. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: pass an AVFormatContext to ff_parse_fmtp()Anton Khirnov2014-07-09
| | | | Use it for logging, instead of NULL or the stream codec context.

* rtpproto: Move rtpproto specific function declarations to a separate headerMartin Storsjö2013-07-31
| | | | | | | Mixing these with the rtp depacketizer functions in rtpdec.h is no good. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Increase max rtp packet size to 8192Andrew Van Til2013-04-09
| | | | | | This fixes connecting to "Ceton InfiniTV4 PCIe & USB". Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Split mpegts parsing to a normal depacketizerMartin Storsjö2013-01-20
| | | | | | | This gets rid of a number of special cases from the common rtpdec code. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtsp: Support decryption of SRTP signalled via RFC 4568 (SDES)Martin Storsjö2013-01-15
| | | | | | | | | | | | | | This only takes care of decrypting incoming packets; the outgoing RTCP packets are not encrypted. This is enough for some use cases, and signalling crypto keys for use with outgoing RTCP packets doesn't fit as simply into the API. If the SDP demuxer is hooked up with custom IO, the return packets can be encrypted e.g. via the SRTP protocol. If the SRTP keys aren't available within the SDP, the decryption can be handled externally as well (when using custom IO). Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Make variables that should wrap unsignedMartin Storsjö2013-01-14
| | | | | | | This makes the behaviour defined when they wrap around. The value assigned to expected_prior was a uint32_t already. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Send a valid "delay since SR" value in the RTCP RR packetsMartin Storsjö2013-01-12
| | | | | | | | | | | Previously, we always signalled a zero time since the last RTCP SR, which is dubious. The code also suggested that this would be the difference in RTP NTP time units (32.32 fixed point), while it actually is in in 1/65536 second units. (RFC 3550 section 6.4.1) Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Support sending RTCP feedback packetsMartin Storsjö2013-01-08
| | | | | | | | | | | | | | | | | | | | | This sends NACK for missed packets and PLI (picture loss indication) if a depacketizer indicates that it needs a new keyframe, according to RFC 4585. This is only enabled if the SDP indicated that feedback is supported (via the AVPF or SAVPF profile names). The feedback packets are throttled to a certain maximum interval (currently 250 ms) to make sure the feedback packets don't eat up too much bandwidth (which might be counterproductive). The RFC specifies a more elaborate feedback packet scheduling. The feedback packets are currently sent independently from normal RTCP RR packets, which is not totally spec compliant, but works fine in the environments I've tested it in. (RFC 5506 allows this, but requires a SDP attribute for enabling it.) Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Store the dynamic payload handler in the rtpdec contextMartin Storsjö2013-01-08
| | | | | | | This allows calling other dynamic payload handler functions if needed. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtsp: Add support for depacketizing RTP data via custom IOMartin Storsjö2013-01-03
| | | | | | | | | | | | | | | | | | To use this, set sdpflags=custom_io to the sdp demuxer. During the avformat_open_input call, the SDP is read from the AVFormatContext AVIOContext (ctx->pb) - after the avformat_open_input call, during the av_read_frame() calls, the same ctx->pb is used for reading packets (and sending back RTCP RR packets). Normally, one would use this with a read-only AVIOContext for the SDP during the avformat_open_input call, then close that one and replace it with a read-write one for the packets after the avformat_open_input call has returned. This allows using the RTP depacketizers as "pure" demuxers, without having them tied to the libavformat network IO. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpdec: Improve some commentsMartin Storsjö2012-12-12
| | | | | | | The previous comment about the buffer was wildly inaccurate and misleading. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec: Remove unused context variablesMartin Storsjö2012-12-12
| | | | | | | These stem from back when both the rtp muxer and rtp depacketizing shared the same struct. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpdec: Emit timestamps for packets before the first RTCP packet, tooMartin Storsjö2011-01-01
| | | | | | | | 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

* Revert svn rev 21857, readd first_rtcp_ntp_time in RTPDemuxContextMartin Storsjö2010-04-20
| | | | | | | | | | | In order to sync RTP streams that get their initial RTCP timestamp at different times, propagate the NTP timestamp of the first RTCP packet to all other streams.
