Some mobile distros seem to be under assumption that playbin3 is required to
get HW accel and setting this env by default is good idea. Both are wrong.
Check this env presence to avoid problems as factory will always return
playbin3 if set (even if playbin2 was requested).
Someone might be holding a copied media info in which case tag
list ref count is not 1. Use gst_tag_list_make_writable to
assure that ref count is 1, so we can insert more tags into the list.
There is no guarantee that received later tags also contain values from
earlier ones, as they might come from different element.
Combine them instead while replacing old values with newer ones.
The video/audio decoder changed signal was not working correctly in case of
multiple streams with multiple decoders in single file.
We need to listen to the current-(video/audio) signal, when it changes find
corresponding "input-selector", get stream ID from its active pad and then
find the decoder in the pipeline that handles this stream ID. Similarly for
playbin3, but use stream ID from the "streams-selected" signal.
We change few default plugin ranks during init to whitelist them, but we do not update
their values from GST_PLUGIN_FEATURE_RANK env afterwards, so do that.
The ENV should be preferred over default config.
Add missing PiP icons from web devel kit. Also add play/pause
icons at the right size and remove all workarounds/scaling
implemented or these two.
Playback icons are always two bars for pause and triangle for play,
so hopefully this will not be problematic, as this guaranties the
right size for them that Adwaita unfortunately cannot provide.
Initializes GStreamer library and tweaks some of its defaults to our liking.
This also allows usage of GstClapper API alone without importing GStreamer on the implementation side.
It changes preferred hardware acceleration order (depending on plugins versions) into:
v4l2sl -> nv -> va -> vaapi -> v4l2
If for some reason GTK ended up with using EGL with GLES instead of OpenGL and user
did not specify anything other, use it by default in gstreamer part of the app too.
Before playback starts our video display size is zero, no point in sending navigation events in such case.
Latest gstreamer git prints criticals in such case.
Also do not send mouse navigaion when element is paused and skip keypresses when below paused state.
Instead of using PulseAudio sink and making a round way through pipewire-pulse,
access and use PipeWire directly for audio output when user sets env var
GST_CLAPPER_USE_PIPEWIRE=1
Not much benefit from using this function and unlike g_idle_add_full it
does not allow to skip a frame when previous one was not finished (slow HW).
This reverts commit f8a7abe195.
