Add support for premultiplied alpha flag detection when creating GdkMemoryTextures.
Also check if overlays have premultiplied alpha and if they do set this flag for
their video info, so it will be detected when creating a GdkMemoryTexture out of them.
Fixes performance issues with karaoke subtitles, as now GTK does not have to perform
unnecessary multiplication.
Make GL base importer class and all its subclasses that access parent props,
use a different mutex lock then the main importer class.
This way main importer class can continue processing buffers without waiting for
GL-based subclasses, as most GL operations (e.g. upload) are time consuming.
We cannot compile app as a whole on MS Windows yet, but with those changes it is now possible to compile and run our new video sink alone on Windows OS
We do not want to build GL-based importers when GTK GL windowing support is missing,
which might happen because of missing deps or on unsupported platform
Too many problems with VAAPI decodebin, meanwhile VA works fine and there is already
a pending MR on GStreamer to enable it by default, so we do that a little early.
We also do promise working HW accel out of box, so enable all common NVDEC elements too.
They can always be disabled back in player preferences window if any problems do happen.
We can now remove the alternations of v4l2codecs as those are PRIMARY+1 by default and we
now require GStreamer 1.20+ so no need for version checking there too.
Fixes#236
No need to auto build rawimporter if we are building gluploader as it
will be always loaded on startup, but never used.
Skip the build of it when its meson option is set to "auto".
Add "clappergluploader" module which uses "glupload" and "glcolorconvert" internally,
allowing either uploading RAW system memory into GPU with GL colorspace conversion or
importing DMABufs into GL memory and making a GdkTexture out of them at one go.
Add new GStreamer plugin with custom video sink for Clapper video player.
The main difference is that unlike the old one, this does not operate using `GtkGLArea`
anymore, but processes and displays `GdkTextures` directly through `GtkPicture` widget.
Also this one is installed like any other GStreamer plugin, thus can be used via
`gst-launch-1.0` binary or even by other GTK4 apps if they wish to integrate it.
In order to not depend on GL stuff at build time, this plugin uses seperate GModules
called "importers" in order to import different kind of memories into GdkTexture. This
allows expanding its capabilities further then we were able to do before.
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.
