* Fix memleak caused by the fact that url_open_buf() allocates a contextRonald S. Bultje2008-11-17
| | | | | | | | | | | when calling, but url_close_buf() doesn't free it. The better solution is to not allocate it at all, init it with init_put_byte() and then not have to close it at all. In the case where we do need to hold it around for longer than within the function context, we allocate it with av_alloc_put_byte() and free it with av_free() instead.

* Implement RDTDemuxContext, which contains RDT-specific data (similar toRonald S. Bultje2008-10-04
| | | | | | | RTPDemuxContext for RTP) for these streams where the transport protocol is RDT (as served by Realmedia servers). Originally committed as revision 15544 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change function prototype of RTPDynamicPayloadHandler.parse_packet() toRonald S. Bultje2008-10-04
| | | | | | | | | not use RTPDemuxContext, but rather take a pointer to the payload context directly. This allows using payload handlers regardless over the transport over which they were sent, and prepares for the introduction of a future RDTDemuxContext. See discussion in "RDT/Realmedia patches #2" thread on ML. Originally committed as revision 15541 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | the use of rdt_parse_packet(). See "RDT/Realmedia patches #2" thread on ML. Originally committed as revision 15497 to svn://svn.ffmpeg.org/ffmpeg/trunk
* This patch refactors RDT packet header parsing so that it can be used inRonald S. Bultje2008-10-01
| | | | | | | | rtsp.c to detect the ID of the packet source also in case of TCP streams. This allows proper playback of RDT streams with multiple stream types, e.g. audio + video. Accepted by LucaB in "RDT/Realmedia patches #2" thread on ML. Originally committed as revision 15496 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove access to rdt_data struct in functions called outside of theRonald S. Bultje2008-09-30
| | | | | | | | | DynamicProtocol* context. Doing so could lead to problems if we're accessing Real servers serving non-RDT data (or the other way around). Temporarily, this patch adds a _subscribe2() function which will soon be removed in one of the subsequent commits. OK'ed by Luca in "Realmedia patch" thread on ML. Originally committed as revision 15483 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement RDT-specific data parsing routines. After these changes, simpleRonald S. Bultje2008-09-07
| | | | | | | playback of RTSP/RDT streams should work. See discussion in "Realmedia patch" thread on ML. Originally committed as revision 15237 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement a RDT-specific SET_PARAMETER command that subscribes to theRonald S. Bultje2008-09-07
| | | | | | | first stream in a RTSP/RDT session. See discussion in "Realmedia patch" thread on ML. Originally committed as revision 15235 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add dynamic payload handlers to rdt.c. These follow the same API as the onesRonald S. Bultje2008-09-07
| | | | | | | | | | | | | | | | | | in rtpdec.c, so that they can be shared and used in the same way in rtsp.c. The handlers, since they are specific for RDT, are registered in rdt.c and a new registration function is thus called from allformats.c. The dynamic payload handler also implements RDT-specific SDP-line parsing for OpaqueData and StartTime, which are specific for RDT and needed for proper playback. OpaqueData contains one or a list ("MLTI") of "MDPR" chunks that can be parsed by the rmdec.c function ff_rm_read_mdpr_codecdata(). To use this function, we create a new rdt_demuxer, which has the same private data as the rm_demuxer. The resulting AVFormatContext created with _open_stream() can thus be used to call functions in the RM demuxer. See discussion in "Realmedia patch" thread on ML.

* Implement Realmedia/RTSP-compatible SETUP command. This includes calculationRonald S. Bultje2008-09-03
of the "RealChallenge2" response, which is some sort of authentication. See discussion in "Realmedia patch" thread on ffmpeg-devel. Originally committed as revision 15170 to svn://svn.ffmpeg.org/ffmpeg/trunk
