# for instance, the HTTP FLV stream clients.
|
|
play {
|
|
# the minimal packets send interval in ms,
|
|
# used to control the ndiff of stream by srs_rtmp_dump,
|
|
# for example, some device can only accept some stream which
|
|
# delivery packets in constant interval(not cbr).
|
|
# @remark 0 to disable the minimal interval.
|
|
# @remark >0 to make the srs to send message one by one.
|
|
# @remark user can get the right packets interval in ms by srs_rtmp_dump.
