Gst 1.22 gst-play.c looping a video

[Arnaud Loonstra]

Hi all,

I'm trying to use gst-play.c from 
https://github.com/GStreamer/gstreamer/blob/1.22/subprojects/gst-plugins-base/tools/gst-play.c 
as a base for looping a video. I am using gstreamer 1.22 on a Linux 
x86_64 Debian trixie machine.

At first I thought I'd use the play_about_to_finish callback to issue a 
play_do_seek to 0. However that didn't really work.

https://github.com/GStreamer/gstreamer/blob/a89f33c86c8ba6731a8177721de90b6e07dbc25c/subprojects/gst-plugins-base/tools/gst-play.c#L819

Second attempt was to use GST_MESSAGE_EOS to issue the `play_do_seek 
(play, 0, play->rate, play->trick_mode);`

https://github.com/GStreamer/gstreamer/blob/a89f33c86c8ba6731a8177721de90b6e07dbc25c/subprojects/gst-plugins-base/tools/gst-play.c#L451

This works a bit better but still not very reliable. Some files just 
freeze at the end and if it does work it sometimes freezes randomly. 
Stracktrace points to play_timeout being handled.

But what would be the best approach to loop the playing video preferably 
gapless/seamless?

Any pointers appreciated.

Rg,

Arnaud
