* Camera example: Remove exposure sliderBror Wetlesen Vedeld2025-09-031-7/+0
| | | | | | | | | | | | | | QCamera API has no way of checking whether the "exposureCompensation" property is supported. This means the slider has no effect, and we have no mechanism for hiding it. This patch removes the slider from the example.

* Add HasHdrContent to QMediaMetaData::Key enumerationJøger Hansegård2024-05-141-5/+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.

* Improve ffmpeg camera formats selection on darwin OSArtem Dyomin2023-03-201-21/+0
| | | | | | | | | | | | | | | | | | Handled a bunch of corner cases, briefly they are: - handle the case when ffmpeg videotoolbox doesn't support format. From now, it's optionally available to use sw frame or choose another format. Both approaches are working, but for now, the first one is prefferable. - handle the rare case when device output formats don't contain camera format. - improve the best camera format selection, it'll take into account an opoortunity to use hw acceleration for the format. - improve logging.

* Adjust multimedia examples to use new QPermission APIIvan Solovev2023-02-081-0/+44
| | | | | | | | | | | | | | | | Now when the library itself does not request permissions, that needs to be done on the user application level. This patch updates all examples to query the required permissions. As there is no QML API yet, the QML examples do it directly from main. Note: the WRITE_EXTERNAL_STORAGE Android permission is not handled by this patch, because it's currently not supported by the QPermission API.

* Let examples show up in Qt Creator againKai Köhne2022-09-051-0/+387
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.
