[suite recv_cmd]
caption = receivers
[subcommand afh]
purpose = make an audio stream from a local file
[description]
The afh (audio format handler) receiver extracts selected parts of
the given audio file without decoding the file. Only complete chunks
with respect to the underlying audio format are extracted.
[/description]
[option filename]
short_opt = f
summary = file to open
typestr = filename
arg_info = required_arg
arg_type = string
[option begin-chunk]
short_opt = b
summary = skip the beginning of the file
typestr = chunk_num
arg_info = required_arg
arg_type = int32
[help]
The argument must be an integer between -num_chunks and num_chunks -
1, inclusively, where num_chunks is the total number of chunks. If
chunk_num is negative, the given number of chunks are counted backwards
from the end of the file. For example --begin-chunk -100 instructs
the afh receiver to start at chunk num_chunks - 100. This is useful
for cutting off the beginning of an audio file.
[/help]
[option end-chunk]
short_opt = e
summary = only write up to chunk chunk_num
typestr = chunk_num
arg_info = required_arg
arg_type = int32
[help]
For the chunk_num argument the same rules as for --begin-chunk
apply. The default is to write up to the last chunk.
[/help]
[option just-in-time]
short_opt = j
summary = use timed writes
[help]
Write the specified data chunks 'just in time', i.e., delay the write
until data is needed by the decoder/player for an uninterrupted audio
stream. This may be useful for third-party software.
[/help]
[option no-header]
short_opt = h
summary = do not write an audio file header
[help]
Some audio formats store information about the audio file in
a format-specific header which is needed to decode any part of
the file. For such formats the afh receiver generates a suitable
header. This option changes the default behaviour, i.e. no header
is written.
[/help]
[subcommand http]
purpose = receive an audio stream over HTTP
m4_include(host.m4)
m4_include(port.m4)
[subcommand udp]
purpose = receive an audio stream over UDP
[option host]
short_opt = i
summary = IP address or hostname
typestr = host
arg_info = required_arg
arg_type = string
default_val = 224.0.1.38
[help]
The default address resolves to DANTZ.MCAST.NET and activates
multicast.
[/help]
m4_include(port.m4)
[option iface]
summary = receiving udp multicast interface
typestr = iface-name
arg_info = required_arg
arg_type = string
