* Add HasHdrContent to QMediaMetaData::Key enumerationJøger Hansegård6 days1-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | The HasHdrContent metadata key can be used to determine if a video track potentially contains HDR video. QMediaMetaData::value(QMediaMetaData::HasHdrContent) will return true when the decoder reports that the video uses ColorTransfer_ST2084 or ColorTransfer_STD_B67. These are color transfers used with Dolby Vision videos, for example HDR video recorded with an iPhone. Note that even if HasHdrContent is true, the video may still not utilize the extended dynamic range. This simplified approach is chosen because it is fast, and does not require decoding video frames to determine the actual range being used. Qt Multimedia still does not support proper display of HDR content, but the new metadata key can be used to determine if the video is a SDR video that will be presented correctly. Supported on FFmpeg media backend only.

* Fix next/previous buttons issue in Media Player app exampleJakub Wincenciak2023-11-151-2/+2
| | | | | | | | | | | | | | | | If we loaded several videos, clicking on the next button moved on to the next video, but if we did this on the last video, the app would select an 'empty' video and only on the second click would it move to the front of the list. The same was happening with the previous button. The problem was the function that determines the index of the next preceding video, so I fixed it.

* Media Player Example: Set volume slider minimum width to default sizeLars Sutterud2023-11-141-0/+3
| | | | | | | | | | | | | | | | This change fixes a design bug where decreasing the window width would decrease the volume slider width gradually down to zero. A volume slider needs a certain width to be useful, therefore the default slider width from QSlider::sizeHint() is now used as its minimum size. This is done by changing its horizontol QSizePolicy to MinimumExpanded. As a result the volume slider now has a constant width, which is the same apprach used in e.g. Apple Music and VLC player.

* Let examples show up in Qt Creator againKai Köhne2022-09-0518-0/+2760
Fix an issue where the relative paths in the generated examples-manifest.xml did miss the parent directory, effectively blocking the examples from being shown in the Qt Creator Welcome screen. This broke in commit c403e775f60a, where the exampledirs path was changed from "../../../examples" to "../../../examples/multimedia" and "../../../examples/multimediawidgets". This made qdoc miss the "multimedia" and "multimediawidgets" directories in the generated paths. To fix this, the patch * moves all the multimediawidgets examples to multimedia * sets examplesinstallpath to "multimedia" The unification of directories is needed because there can be only one examplesinstallpath per qdoc project.
