gstout-buffer-duration #247

Open antonellocaroli opened 2 years ago

antonellocaroli commented 2 years ago

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.
https://github.com/hzeller/gmrender-resurrect/blob/4ac7d8914dc089651ae9d6c421ecda8f4d0ab5e3/src/output_gstreamer.c#L399-L400

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. https://github.com/hzeller/gmrender-resurrect/blob/4ac7d8914dc089651ae9d6c421ecda8f4d0ab5e3/src/output_gstreamer.c#L515-L522

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.
