* media: Documentation: media: *_DEFAULT targets for subdevsRicardo Ribalda Delgado2019-11-101-1/+3
| | | | | | | | | | | | | Some sensors have optical blanking areas, this is, pixels that are painted and do not account for light, only noise. These special pixels are very useful for calibrating the sensor, but should not be displayed on a DEFAULT target.

* media: uapi: h264: clarify expected scaling_list_4x4/8x8 orderJonas Karlman2019-11-091-2/+6
| | | | | | | | | | | | | | | | | Clarify that the expected order of scaling lists should follow the order they are listed in the H264 standard. The expected scaling list order, for 4x4: Intra Y, Intra Cb, Intra Cr, Inter Y, Inter Cb, Inter Cr, for 8x8: Intra Y, Inter Y, Intra Cb, Inter Cb, Intra Cr, Inter Cr. Also clarify that the values in a scaling list should be in matrix order, the same value order that vaapi, vdpau and nvdec use.

| | | | | | | | | | | | | | | | Add mean window size parameter for debayer filter as a control in vimc-debayer. vimc-debayer was patched to allow changing mean window parameter of the filter without needing to reload the driver. The parameter can now be set using a v4l2-ctl control(mean_window_size).

* media: v4l: Add definitions for HEVC stateless decodingPaul Kocialkowski2019-10-244-3/+580
| | | | | | | | | | | | | | | | | | | | | | | | | | This introduces the required definitions for HEVC decoding support with stateless VPUs. The controls associated to the HEVC slice format provide the required meta-data for decoding slices extracted from the bitstream. They are not exported to the public V4L2 API since reworking this API will likely be needed for covering various use-cases and new hardware. Multi-slice decoding is exposed as a valid decoding mode to match current H.264 support but it is not yet implemented. The interface comes with the following limitations: * No custom quantization matrices (scaling lists); * Support for a single temporal layer only; * No slice entry point offsets support; * No conformance window support; * No VUI parameters support; * No support for SPS extensions: range, multilayer, 3d, scc, 4 bits; * No support for PPS extensions: range, multilayer, 3d, scc, 4 bits.

| | | | | | | | | | | | | | | | | | Since the uapi does not contain the num_ref_idx_active_override_flag, drivers for decoders that do not parse slices themselves don't know how to choose between the num_ref_idx_l[01]_default_active and the num_ref_idx_l[01]_active override fields. Instead, userspace must set the override fields to the default values if the slice does not have the num_ref_idx_active_override flag set. The drivers will then always enable the override internally and ignore the default fields completely. Clarify this requirement in the API documentation.

These include capability enumeration, initialization, decoding, seek, pause, dynamic resolution change, drain and end of stream. Specifics of the above have been discussed during Media Workshops at LinuxCon Europe 2012 in Barcelona and then later Embedded Linux Conference Europe 2014 in Düsseldorf. The de facto Codec API that originated at those events was later implemented by the drivers we already have merged in mainline, such as s5p-mfc or coda. The only thing missing was the real specification included as a part of Linux Media documentation. Fix it now and document the decoder part of the Codec API.

This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected.

If this flag is set, then this pre-parsing step is not required (but still possible, of course).

Note that this is independent of the H264 decoding mode, which specifies the granularity of the decoding operations. Either in frame-based or slice-based mode, this new control will allow to define the start code expected on H264 slices.

While this was a practical choice at the time, it necessitates choosing which one of the many parallel mbus pixel codes to use, for on the serial busses these formats are effectively all equivalent. The practice has always been to use the pixel code that describes a bus that transfers a single sample per clock. Document this.
