media player (gtk-play)

[Gary Thomas]

Ross,

Do you know if there is a way to tell gtk-play what gstreamer
back-end(s) to use?  In particular, for my i.MX6 board, it is
not choosing the video plugin I think it should and it would be
nice to test if it does the right thing if the correct plugin
is used.

by video plugin, you mean the decoder or the video sink?

if it's the sink:

gst-play --videosink <foo> --audiosink <bar>

if it's the decoder, you can't choose on the command line, the
application will just rely on playbin, so you need to configure your
plugins (and their priorities) so that playbin would pick the most
appropriate plugin.

cheers.

This is what I'm looking for except I need to send these to gtk-play,
the GUI front-end.

I guess there's a few solutions:

1) Patch gst-player (upstream is very responsive!) to add options to pass
these hints to the playbin
2) Delete the plugins you don't want it to use
3) Use gst-launch directly to do these tests (gst-launch playbin
video-sink=foosink uri=...)

For (1) this should be a fairly simple matter of passing the sink name,
then constructing that element and passing it as the audio-sink/video-sink
property on the playbin.

You can try

export GST_DEBUG=GST_ELEMENT_FACTORY:3

then run gstreamer. Log indicates which elements are being used.
