| 41 | * |
| 42 | * @{ |
| 43 | * |
| 44 | * The video processing API uses the same paradigm as for decoding: |
| 45 | * - Query for supported filters; |
| 46 | * - Set up a video processing pipeline; |
| 47 | * - Send video processing parameters through VA buffers. |
| 48 | * |
| 49 | * \section api_vpp_caps Query for supported filters |
| 50 | * |
| 51 | * Checking whether video processing is supported can be performed |
| 52 | * with vaQueryConfigEntrypoints() and the profile argument set to |
| 53 | * #VAProfileNone. If video processing is supported, then the list of |
| 54 | * returned entry-points will include #VAEntrypointVideoProc. |
| 55 | * |
| 56 | * \code |
| 57 | * VAEntrypoint *entrypoints; |
| 58 | * int i, num_entrypoints, supportsVideoProcessing = 0; |
| 59 | * |
| 60 | * num_entrypoints = vaMaxNumEntrypoints(); |
| 61 | * entrypoints = malloc(num_entrypoints * sizeof(entrypoints[0]); |
| 62 | * vaQueryConfigEntrypoints(va_dpy, VAProfileNone, |
| 63 | * entrypoints, &num_entrypoints); |
| 64 | * |
| 65 | * for (i = 0; !supportsVideoProcessing && i < num_entrypoints; i++) { |
| 66 | * if (entrypoints[i] == VAEntrypointVideoProc) |
| 67 | * supportsVideoProcessing = 1; |
| 68 | * } |
| 69 | * \endcode |
| 70 | * |
| 71 | * Then, the vaQueryVideoProcFilters() function is used to query the |
| 72 | * list of video processing filters. |
| 73 | * |
| 74 | * \code |
| 75 | * VAProcFilterType filters[VAProcFilterCount]; |
| 76 | * unsigned int num_filters = VAProcFilterCount; |
| 77 | * |
| 78 | * // num_filters shall be initialized to the length of the array |
| 79 | * vaQueryVideoProcFilters(va_dpy, vpp_ctx, &filters, &num_filters); |
| 80 | * \endcode |
| 81 | * |
| 82 | * Finally, individual filter capabilities can be checked with |
| 83 | * vaQueryVideoProcFilterCaps(). |
| 84 | * |
| 85 | * \code |
| 86 | * VAProcFilterCap denoise_caps; |
| 87 | * unsigned int num_denoise_caps = 1; |
| 88 | * vaQueryVideoProcFilterCaps(va_dpy, vpp_ctx, |
| 89 | * VAProcFilterNoiseReduction, |
| 90 | * &denoise_caps, &num_denoise_caps |
| 91 | * ); |
| 92 | * |
| 93 | * VAProcFilterCapDeinterlacing deinterlacing_caps[VAProcDeinterlacingCount]; |
| 94 | * unsigned int num_deinterlacing_caps = VAProcDeinterlacingCount; |
| 95 | * vaQueryVideoProcFilterCaps(va_dpy, vpp_ctx, |
| 96 | * VAProcFilterDeinterlacing, |
| 97 | * &deinterlacing_caps, &num_deinterlacing_caps |
| 98 | * ); |
| 99 | * \endcode |
| 100 | * |
| 101 | * \section api_vpp_setup Set up a video processing pipeline |
| 102 | * |
| 103 | * A video processing pipeline buffer is created for each source |
| 104 | * surface we want to process. However, buffers holding filter |
| 105 | * parameters can be created once and for all. Rationale is to avoid |
| 106 | * multiple creation/destruction chains of filter buffers and also |
| 107 | * because filter parameters generally won't change frame after |
| 108 | * frame. e.g. this makes it possible to implement a checkerboard of |
| 109 | * videos where the same filters are applied to each video source. |
| 110 | * |
| 111 | * The general control flow is demonstrated by the following pseudo-code: |
| 112 | * \code |
| 113 | * // Create filters |
| 114 | * VABufferID denoise_filter, deint_filter; |
| 115 | * VABufferID filter_bufs[VAProcFilterCount]; |
| 116 | * unsigned int num_filter_bufs; |
| 117 | * |
| 118 | * for (i = 0; i < num_filters; i++) { |
| 119 | * switch (filters[i]) { |
| 120 | * case VAProcFilterNoiseReduction: { // Noise reduction filter |
| 121 | * VAProcFilterParameterBuffer denoise; |
| 122 | * denoise.type = VAProcFilterNoiseReduction; |
| 123 | * denoise.value = 0.5; |
| 124 | * vaCreateBuffer(va_dpy, vpp_ctx, |
| 125 | * VAProcFilterParameterBufferType, sizeof(denoise), 1, |
| 126 | * &denoise, &denoise_filter |
| 127 | * ); |
| 128 | * filter_bufs[num_filter_bufs++] = denoise_filter; |
| 129 | * break; |
| 130 | * } |
| 131 | * |
| 132 | * case VAProcFilterDeinterlacing: // Motion-adaptive deinterlacing |
| 133 | * for (j = 0; j < num_deinterlacing_caps; j++) { |
| 134 | * VAProcFilterCapDeinterlacing * const cap = &deinterlacing_caps[j]; |
| 135 | * if (cap->type != VAProcDeinterlacingMotionAdaptive) |
| 136 | * continue; |
| 137 | * |
| 138 | * VAProcFilterParameterBufferDeinterlacing deint; |
| 139 | * deint.type = VAProcFilterDeinterlacing; |
| 140 | * deint.algorithm = VAProcDeinterlacingMotionAdaptive; |
| 141 | * vaCreateBuffer(va_dpy, vpp_ctx, |
| 142 | * VAProcFilterParameterBufferType, sizeof(deint), 1, |
| 143 | * &deint, &deint_filter |
| 144 | * ); |
| 145 | * filter_bufs[num_filter_bufs++] = deint_filter; |
| 146 | * } |
| 147 | * } |
| 148 | * } |
| 149 | * \endcode |
| 150 | * |
| 151 | * Once the video processing pipeline is set up, the caller shall check the |
| 152 | * implied capabilities and requirements with vaQueryVideoProcPipelineCaps(). |
| 153 | * This function can be used to validate the number of reference frames are |
| 154 | * needed by the specified deinterlacing algorithm, the supported color |
| 155 | * primaries, etc. |
| 156 | * \code |
| 157 | * // Create filters |

| 1379 | * \brief 3DLUT filter parametrization. |
| 1380 | * |
| 1381 | * 3DLUT (Three Dimensional Look Up Table) is often used when converting an image or a video frame |
| 1382 | * from one color representation to another, for example, when converting log and gamma encodings, |
| 1383 | * changing the color space, applying a color correction, changing the dynamic range, gamut mapping etc. |
| 1384 | * |
| 1385 | * This buffer defines 3DLUT attributes and memory layout. The typical 3DLUT has fixed number(lut_size) |
| 1386 | * per dimension and memory layout is 3 dimensional array as 3dlut[stride_0][stride_1][stride_2] (lut_size |
| 1387 | * shall be smaller than stride_0/1/2). |
| 1388 | * |
| 1389 | * API user should query hardware capability by using the VAProcFilterCap3DLUT to get the 3DLUT attributes |
| 1390 | * which hardware supports, and use these attributes. For example, if the user queries hardware, the API user |
| 1391 | * could get caps with 3dlut[33][33][64] (lut_size = 33, lut_stride[0/1/2] = 33/33/64). API user shall not |
| 1392 | * use the attributes which hardware can not support. |
| 1393 | * |
| 1394 | * 3DLUT is usually used to transform input RGB/YUV values in one color space to output RGB values in another |
| 1395 | * color space. Based on 1) the format and color space of VPP input and output and 2) 3DLUT memory layout and |
| 1396 | * channel mapping, driver will enable some color space conversion implicitly if needed. For example, the input of |
| 1397 | * VPP is P010 format in BT2020 color space, the output of VPP is NV12 in BT709 color space and the 3DLUT channel |
| 1398 | * mapping is VA_3DLUT_CHANNEL_RGB_RGB, driver could build the data pipeline as P010(BT2020)->RGB(BT2020) |
| 1399 | * ->3DULT(BT709)->NV12(BT709). Please note, the limitation of 3DLUT filter color space is that the color space of |
| 1400 | * 3DLUT filter input data needs to be same as the input data of VPP; the color space of 3DLUT filter output data |
| 1401 | * needs to be same as the output data of VPP; format does not have such limitation. |
