Negotiate a mutually acceptable configuration with the server to lock 122 down profile, entrypoints, and other attributes that will not change on 123 a frame-by-frame basis. 124 - Create a decode context which represents a "virtualized" hardware decode 125 device 126 - Get and fill decode buffers with picture level, slice level and macroblock 127 level data (depending on entrypoints) 128 - Pass the decode buffers to the server to decode the current frame 129 130 Initialization & Configuration Management 131 132 - Find out supported profiles 133 - Find out entrypoints for a given profile 134 - Find out configuration attributes for a given profile/entrypoint pair 135 - Create a configuration for use by the decoder 136 137 */ 138 139 typedef void* VADisplay; /* window system dependent */ 140 141 typedef int VAStatus; /* Return status type from functions */ 142 /* Values for the return status */ 143 #define VA_STATUS_SUCCESS 0x00000000 144 #define VA_STATUS_ERROR_OPERATION_FAILED 0x00000001 145 #define VA_STATUS_ERROR_ALLOCATION_FAILED 0x00000002 146 #define VA_STATUS_ERROR_INVALID_DISPLAY 0x00000003 147 #define VA_STATUS_ERROR_INVALID_CONFIG 0x00000004 148 #define VA_STATUS_ERROR_INVALID_CONTEXT 0x00000005 149 #define VA_STATUS_ERROR_INVALID_SURFACE 0x00000006 150 #define VA_STATUS_ERROR_INVALID_BUFFER 0x00000007 151 #define VA_STATUS_ERROR_INVALID_IMAGE 0x00000008 152 #define VA_STATUS_ERROR_INVALID_SUBPICTURE 0x00000009 153 #define VA_STATUS_ERROR_ATTR_NOT_SUPPORTED 0x0000000a 154 #define VA_STATUS_ERROR_MAX_NUM_EXCEEDED 0x0000000b 155 #define VA_STATUS_ERROR_UNSUPPORTED_PROFILE 0x0000000c 156 #define VA_STATUS_ERROR_UNSUPPORTED_ENTRYPOINT 0x0000000d 157 #define VA_STATUS_ERROR_UNSUPPORTED_RT_FORMAT 0x0000000e 158 #define VA_STATUS_ERROR_UNSUPPORTED_BUFFERTYPE 0x0000000f 159 #define VA_STATUS_ERROR_SURFACE_BUSY 0x00000010 160 #define VA_STATUS_ERROR_FLAG_NOT_SUPPORTED 0x00000011 161 #define VA_STATUS_ERROR_INVALID_PARAMETER 0x00000012 162 #define VA_STATUS_ERROR_RESOLUTION_NOT_SUPPORTED 0x00000013 163 #define VA_STATUS_ERROR_UNIMPLEMENTED 0x00000014 164 #define VA_STATUS_ERROR_SURFACE_IN_DISPLAYING 0x00000015 165 #define VA_STATUS_ERROR_INVALID_IMAGE_FORMAT 0x00000016 166 #define VA_STATUS_ERROR_DECODING_ERROR 0x00000017 167 #define VA_STATUS_ERROR_ENCODING_ERROR 0x00000018 168 /** 169 * \brief An invalid/unsupported value was supplied. 170 * 171 * This is a catch-all error code for invalid or unsupported values. 172 * e.g. value exceeding the valid range, invalid type in the context 173 * of generic attribute values. 174 */ 175 #define VA_STATUS_ERROR_INVALID_VALUE 0x00000019 176 /** \brief An unsupported filter was supplied. */ 177 #define VA_STATUS_ERROR_UNSUPPORTED_FILTER 0x00000020 178 /** \brief An invalid filter chain was supplied. */ 179 #define VA_STATUS_ERROR_INVALID_FILTER_CHAIN 0x00000021 180 /** \brief Indicate HW busy (e.g. run multiple encoding simultaneously). */ 181 #define VA_STATUS_ERROR_HW_BUSY 0x00000022 182 #define VA_STATUS_ERROR_UNKNOWN 0xFFFFFFFF 183 184 /* De-interlacing flags for vaPutSurface() */ 185 #define VA_FRAME_PICTURE 0x00000000 186 #define VA_TOP_FIELD 0x00000001 187 #define VA_BOTTOM_FIELD 0x00000002 188 189 /* 190 * Enabled the positioning/cropping/blending feature: 191 * 1, specify the video playback position in the isurface 192 * 2, specify the cropping info for video playback 193 * 3, encoded video will blend with background color 194 */ 195 #define VA_ENABLE_BLEND 0x00000004 /* video area blend with the constant color */ 196 197 /* 198 * Clears the drawable with background color. 199 * for hardware overlay based implementation this flag 200 * can be used to turn off the overlay 201 */ 202 #define VA_CLEAR_DRAWABLE 0x00000008 203 204 /* Color space conversion flags for vaPutSurface() */ 205 #define VA_SRC_BT601 0x00000010 206 #define VA_SRC_BT709 0x00000020 207 #define VA_SRC_SMPTE_240 0x00000040 208 209 /* Scaling flags for vaPutSurface() */ 210 #define VA_FILTER_SCALING_DEFAULT 0x00000000 211 #define VA_FILTER_SCALING_FAST 0x00000100 212 #define VA_FILTER_SCALING_HQ 0x00000200 213 #define VA_FILTER_SCALING_NL_ANAMORPHIC 0x00000300 214 #define VA_FILTER_SCALING_MASK 0x00000f00 215 216 /* 217 * Returns a short english description of error_status 218 */ 219 const char *vaErrorStr(VAStatus error_status); 220 221 /* 222 * Initialization: 223 * A display must be obtained by calling vaGetDisplay() before calling 224 * vaInitialize() and other functions.
