Pad Properties

Parameter Name	Description	Value Type	Available Values [range]	Default	Flags
connect-timeout	Specifies the timeout for connection to the source by setting the curl option (CURLOPT_CONNECTTIMEOUT). If the value is 0, the timeout will be equal to the default curl value of 300 seconds.	Range	[0 – 2147483647]	10	readable, writable
current-playlist-bitrate	Indicates the bitrate (bit/s) of the currently used media playlist specified in the master playlist.	String		null	readable
data-timeout	Specifies the timeout between two subsequently downloaded segments. If during the timeout the next segment doesn’t become available for downloading, the EOS will show up. If the value is set to 0, the component will be continuously waiting for data. In this case, EOS will not come up, except when the #EXT-X-ENDLIST tag is found or if the maximum number of attempts to update the playlist (the max-playlist-updates parameter) is achieved before the playlist changes.	Range	[0 – 2147483647]	10	readable, writable
download-rate	Indicates the current data download rate in bit/s.	String		0,00 bps	readable
download-timeout	Specifies the time frame in seconds for the download of the segment and playlist to finish. If they don’t make it in time, the data is discarded. If the value is set to 0, there will be no limit on segment download time.	Range	[0 – 2147483647]	10	readable, writable
license-state	Indicates the license state.	String		evaluation	readable, writable
location	Specifies the URL or local path to the playlist’s .m3u8 file.	String		“”	readable, writable
max-download-buffer-size	Specifies the input buffer size as the number of segments that will be accumulated and kept if the download rate is sufficient. If the download rate is higher than the data output speed, this parameter limits the number of downloaded segments in this sequence and will download new segments only if there is space available in said sequence.	Range	[0 – 2147483647]	2	readable, writable
max-download-rate	Specifies the download rate limit in bit/s. If the value is set to 0, there will be no limit.	Range	[0 – 2147483647]	0	readable, writable
max-playlist-updates	Specifies the number of attempts to update the media playlist and get a new playlist (different from the current one). If set to 0, the number of attempts is infinite.	Range	[0 – 2147483647]	0	readable, writable
name	Specifies the name of the object.	String		hlssrc0	readable, writable
oem-name	Indicates the OEM name.	String			readable
parent	Specifies the parent of the object.	Object of type GstObject			readable, writable
real-stream-bitrate	Indicates the actual bitrate of the downloaded stream.	String		“0,00 bps”	readable
reinitialization-interval	Specifies the reinitialization interval in seconds. It is a frequency for the source to attempt to download the playlist for the first time. If the value is set to 0, there will be only one initialization attempt. If the playlist is not downloaded, the graph start-up will fail.	Range	[0 – 4294967295]	10	readable, writable
start-position	Specifies the starting point (in %) in the playlist that the source will start downloading segments from. If set to 0, the download will start with the oldest segments. When the value is 100, the newest segments will be downloaded.	Range	[0 – 100]	50	readable, writable
user-agent	Indicates the part of the HTTP request header that is required for client application identification by a server or network node. If this field is empty, the option is not used, and the header part is not inserted in the HTTP request.	String		Elecard HLS client	readable, writable
