Ronald S. Bultje 1a45a9f4c0 Add "AVFormatContext *ctx" (that being the RTSP demuxer's) as first argument
to the parse_packet() function pointer in RTPDynamicProtocolHandlers. This
allows these functions to peek back and retrieve values from the demuxer's
context (or RTSPState). The ASF/RTP payload parser will use this to be able
to parse SDP values (which occur even before the payload ID is given), store
them in the RTSPState and then retrieve them while parsing payload data. See
"[PATCH] RTSP-MS 13/15: add RTSP demuxer AVFormatContext to parse_packet()
function pointer (was: transport context)" mailinglist thread.

Ronald S. Bultje 7c68a17754 Parse the OpaqueData field for every AVStream represented by this "set of
streams" (a single RTSPStream / RDTDemuxContext can represent several
AVStreams, that's just how Real/RDT was designed...). This will fill in
most of the AVStream/AVCodecContext header fields, similar to reading a
RM file header would. See "[PATCH] multi-stream MDPR parsing" thread on
mailinglist.

Ronald S. Bultje 530bca9439 Parse the bitrate field in the ASMRuleBook ("AverageBandwidth") to fill in
the AVStream->AVCodecContext->bit_rate field, which is not in the MDPR block
(the "OpaqueData" SDP field). This allows clients to choose streams based
on their bitrate, which is what most network-players base stream selection
on. (Of course, it is also possible to select based on anything else, that
is entirely up to the client.) See "[PATCH] rdt.c: ASM rulebook bitrate
reading" thread on mailinglist.

Ronald S. Bultje 3ca45429fe Parse the ASMRuleBook SDP line to dynamically create one new AVStream for
each "rule" described in the ASMRuleBook. Each rule represents a stream
of identical content compared to other streams in the same rulebook, but
with a possibly different codec/bitrate/etc. See "[PATCH] rdt.c: ASM
rulebook parsing and AVStream creation" thread on mailinglist.

Ronald S. Bultje 886e89d0d0 Add RMStream object as function argument to public functions so that non-.rm
AVStreams can be used to call these public rmdec.c functions as well, as is

Ronald S. Bultje a15ebf34c7 Don't access RMContext directly in rdt.c. Rather, use the return value of
ff_rm_parse_packet() to indicate whether more audio packets are available
in the demuxer from the last RM frame, and save that in the RDT parsing
context. See patch/discussion in "[PATCH] rdt.c: don't access RMContext"
on ML.

Ronald S. Bultje 7b2a070800 Change function prototype of the sdp_parse_a_line in DynamicProtocolHandler.
This function is called in rtsp.c for each a= line in the SDP of the Describe
response after m= RTSP stream descriptors. The function prototype used to
take an AVStream argument. For RDT, however, every RTSPStream represents
a set of streams of identical content, and can thus represent multiple
AVStreams. Therefore, it should not take an AVStream as argument. This
patch modifies it to accept a AVFormatContext (of the RTSP/SDP demuxer)
instead. See discussion in "[PATCH/RFC] change function prototype of
parse_sdp_a_line" thread on ML.

Ronald S. Bultje a4b8cb3c55 Fix memleak caused by the fact that url_open_buf() allocates a context
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. Discussed in ML
thread "[PATCH] fix small memleak in rdt.c".

Ronald S. Bultje 985b05d3c9 This patch refactors RDT packet header parsing so that it can be used in
rtsp.c to detect the ID of the packet source also in case of TCP streams.

audio + video. Accepted by LucaB in "RDT/Realmedia patches #2" thread on ML.

Ronald S. Bultje ab63fb0360 Remove access to rdt_data struct in functions called outside of the

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.

2008-09-07 01:22:18 +00:00
Ronald S. Bultje ff13ba92fd Add dynamic payload handlers to rdt.c. These follow the same API as the ones
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.
