Similarly as with other properties, we should aim to make this into user config option.
For the time being remove, as our outdated default user-agent seems to be breaking
few HLS streaming services.
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
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.
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
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
Implement a working MPRIS DBus connection with a separate API to control it. Right now only player playback state is reflected and Play/Pause/PlayPause calls work.
Autoplay was causing some racy conditions when loaded with subtitle uri. Make it play after uri loaded signal, but still prevent going from stopped to play 2nd time.
Emit media info updated signal only when media info is initially created and when number/format of tracks changes later. This is needed for GUI to detect resolution change (adaptive streaming) or when user adds external subtitles to current video.
