void ff_rm_free_rmstream ( RMStream rms)

int ff_rm_read_mdpr_codecdata ( AVFormatContext s,
AVIOContext pb,
AVStream st,
RMStream rst,
int  codec_data_size,
const uint8_t mime 
)

Read the MDPR chunk, which contains stream-specific codec initialization parameters.

Parameters
scontext containing RMContext and AVIOContext for stream reading
pbcontext to read the data from
stthe stream that the MDPR chunk belongs to and where to store the parameters read from the chunk into
rstreal-specific stream information
codec_data_sizesize of the MDPR chunk
Returns
0 on success, errno codes on error

int ff_rm_parse_packet ( AVFormatContext s,
AVIOContext pb,
AVStream st,
RMStream rst,
int  len,
AVPacket pkt,
int *  seq,
int  flags,
int64_t  ts 
)

Parse one rm-stream packet from the input bytestream.

Parameters
scontext containing RMContext and AVIOContext for stream reading
pbcontext to read the data from
ststream to which the packet to be read belongs
rstReal-specific stream information
lenpacket length to read from the input
pktpacket location to store the parsed packet data
seqpointer to an integer containing the sequence number, may be updated
flagsthe packet flags
tstimestamp of the current packet
Returns
<0 on error, 0 if a packet was placed in the pkt pointer. A value >0 means that no data was placed in pkt, but that cached data is available by calling ff_rm_retrieve_cache().

int ff_rm_retrieve_cache ( AVFormatContext s,
AVIOContext pb,
AVStream st,
RMStream rst,
AVPacket pkt 
)

Retrieve one cached packet from the rm-context.

The real container can store several packets (as interpreted by the codec) in a single container packet, which means the demuxer holds some back when the first container packet is parsed and returned. The result is that rm->audio_pkt_cnt is a positive number, the amount of cached packets. Using this function, each of those packets can be retrieved sequentially.

Parameters
scontext containing RMContext and AVIOContext for stream reading
pbcontext to read the data from
ststream that this packet belongs to
rstReal-specific stream information
pktlocation to store the packet data
Returns
the number of samples left for subsequent calls to this same function, or 0 if all samples have been retrieved.
