gstout-buffer-duration

[antonellocaroli]

Hi,

I cannot understand what values this setting accepts (min and max)
and what it actually does...
could someone please clarify this for me, thank you!!!

The usage should be documented under the --help-gstout option.

gmrender-resurrect/src/output_gstreamer.c

Lines 399 to 400 in 4ac7d89

	{ "gstout-buffer-duration", 0, 0, G_OPTION_ARG_DOUBLE, &buffer_duration,
	"The size of the buffer in seconds. Set to zero to disable buffering.",

In summary, it accepts a decimal number of seconds to buffer the network stream before playback. The value is scaled to nanoseconds and provided to the gstreamer playbin.

gmrender-resurrect/src/output_gstreamer.c

Lines 515 to 522 in 4ac7d89

	gint64 buffer_duration_ns = round(buffer_duration * 1.0e9);
	Log_info("gstreamer",
	"Setting buffer duration to %" PRId64 "ms",
	buffer_duration_ns / 1000000);
	g_object_set(G_OBJECT(player_),
	"buffer-duration",
	buffer_duration_ns,
	NULL);

The minimum value is 0, or no buffer. The maximum value is probably the maximum value of a gint64 (approax 9.2x10e18 ns, or about 292 years).

I did a test by setting:

--gstout-buffer-duration=300.0

in fact the use of ram changes...and sometimes the play, of course, starts with a certain delay...

so I thought of unplugging the LAN cable to see if the playback would continue (thinking that the stream is stored in RAM), but as soon as I unplugged the cable the playback stops immediately ...

perhaps it would be more functional if there were an input buffer and an output buffer.

Playback and buffering are all handled by gstreamer. This project has no control of how the buffering is implemented.
