| 188 | This document is a user manual describing usage of reference software |
---|
| 189 | for the HEVC project. It applies to version 16.6 |
---|
| 190 | of the software. |

| 198 | \section{General Information} |
---|
| 199 | Reference software is being made available to provide a reference |
---|
| 200 | implementation of the HEVC standard being developed by the Joint |
---|
| 201 | Collaborative Team on Video Coding (JCT-VC) regrouping experts from |
---|
| 202 | ITU-T SG 16 and ISO/IEC SC29 WG11. One of the main goals of the |
---|
| 203 | reference software is to provide a basis upon which to conduct |
---|
| 204 | experiments in order to determine which coding tools provide desired |
---|
| 205 | coding performance. It is not meant to be a particularly efficient |
---|
| 206 | implementation of anything, and one may notice its apparent |
---|
| 207 | unsuitability for a particular use. It should not be construed to be a |
---|
| 208 | reflection of how complex a production-quality implementation of a |
---|
| 209 | future HEVC standard would be. |
---|
| 210 | |
---|
| 211 | This document aims to provide guidance on the usage of the reference |
---|
| 212 | software. It is widely suspected to be incomplete and suggestions for |
---|
| 213 | improvements are welcome. Such suggestions and general inquiries may be |
---|
| 214 | sent to the general JCT-VC email reflector on |
---|
| 215 | \url{jct-vc@lists.rwth-aachen.de} (registration required). |
---|
| 216 | |
---|
| 217 | \subsection*{Bug reporting} |
---|
| 218 | Bugs should be reported on the issue tracker set up at |
---|
| 219 | \url{http://hevc.kw.bbc.co.uk/trac/} |
---|
| 220 | |
---|
| 221 | \section{Installation and compilation} |
---|
| 222 | The software may be retrieved from one of the following SVN servers |
---|
| 223 | (mirrored): |

| 252 | For encoding large picture sizes (like UHDTV) it is strongly advised to build 64-bit |
---|
| 253 | binaries and to use a 64-bit OS. This will allow the software to use more than 2GB of RAM. |

---|
| 282 | |
---|
| 283 | Sample configuration files are provided in the cfg/ folder. |
---|
| 284 | Parameters are defined by the last value encountered on the command line. |
---|
| 285 | Therefore if a setting is set via a configuration file, and then a subsequent |
---|
| 286 | command line parameter changes that same setting, the command line parameter |
---|
| 287 | value will be used. |

| 288 | |
---|
| 289 | \subsection{GOP structure table} |
---|
| 290 | \label{sec:gop-structure} |
---|
| 291 | Defines the cyclic GOP structure that will be used repeatedly |
---|
| 292 | throughout the sequence. The table should contain GOPSize lines, |
---|
| 293 | named Frame1, Frame2, etc. The frames are listed in decoding |
---|
| 294 | order, so Frame1 is the first frame in decoding order, Frame2 is |
---|
| 295 | the second and so on. Among other things, the table specifies all |
---|
| 296 | reference pictures kept by the decoder for each frame. This |
---|
| 297 | includes pictures that are used for reference for the current |
---|
| 298 | picture as well as pictures that will be used for reference in |
---|
| 299 | the future. The encoder will not automatically calculate which |
---|
| 300 | pictures have to be kept for future references, they must |
---|
| 301 | be specified. Note that some specified reference frames for |
---|
| 302 | pictures encoded in the very first GOP after an IDR frame might |
---|
| 303 | not be available. This is handled automatically by the encoder, |
---|
| 304 | so the reference pictures can be given in the GOP structure table |
---|
| 305 | as if there were infinitely many identical GOPs before the |
---|
| 306 | current one. Each line in the table contains the parameters used |
---|
| 307 | for the corresponding frame, separated by whitespace: |
---|
| 308 | |
---|
| 309 | \begin{itemize} |
---|
| 310 | \item[]\textbf{Type}: Slice type, can be either I, P or B. |
---|
| 311 | |
---|
| 312 | \item[]\textbf{POC}: Display order of the frame within a GOP, ranging |
---|
| 313 | from 1 to GOPSize. |
---|
| 314 | |
---|
| 315 | \item[]\textbf{QPOffset}: QP offset is added to the QP parameter to set |
---|
| 316 | the final QP value to use for this frame. |
---|
| 317 | |
---|
| 318 | \item[]\textbf{QPFactor}: Weight used during rate distortion |
---|
| 319 | optimization. Higher values mean lower quality and less bits. Typical |
---|
| 320 | range is between |
---|
| 321 | 0.3 and 1. |
---|
| 322 | |
---|
| 323 | \item[]\textbf{tcOffsetDiv2}: In-loop deblocking filter parameter tcOffsetDiv2 |
---|
| 324 | is added to the base parameter LoopFilterTcOffset_div2 to set the final tc_offset_div2 |
---|
| 325 | parameter for this picture signalled in the slice segment header. The final |
---|
| 326 | value of tc_offset_div2 shall be an integer number in the range $-6..6$. |
---|
| 327 | |
---|
| 328 | \item[]\textbf{betaOffsetDiv2}: In-loop deblocking filter parameter betaOffsetDiv2 |
---|
| 329 | is added to the base parameter LoopFilterBetaOffset_div2 to set the final beta_offset_div2 |
---|
| 330 | parameter for this picture signalled in the slice segment header. The final |
---|
| 331 | value of beta_offset_div2 shall be an integer number in the range $-6..6$. |
---|
| 332 | |
---|
| 333 | \item[]\textbf{temporal_id}: Temporal layer of the frame. A frame cannot |
---|
| 334 | predict from a frame with a higher temporal id. If a frame with higher |
---|
| 335 | temporal IDs is listed among a frame's reference pictures, it is |
---|
| 336 | not used, but is kept for possible use in future frames. |
---|
| 337 | |
---|
| 338 | \item[]\textbf{num_ref_pics_active}: Size of reference picture lists L0 |
---|
| 339 | and L1, indicating how many reference pictures in each direction that |
---|
| 340 | are used during coding. |
---|
| 341 | |
---|
| 342 | \item[]\textbf{num_ref_pics}: The number of reference pictures kept for |
---|
| 343 | this frame. This includes pictures that are used for reference for the |
---|
| 344 | current picture as well as pictures that will be used for reference in |
---|
| 345 | the future. |
---|
| 346 | |
---|
| 347 | \item[]\textbf{reference_pictures}: A space-separated list of |
---|
| 348 | num_ref_pics integers, specifying the POC of the reference pictures |
---|
| 349 | kept, relative the POC of the current frame. The picture list shall be |
---|
| 350 | ordered, first with negative numbers from largest to smallest, followed |
---|
| 351 | by positive numbers from smallest to largest (e.g. \verb|-1 -3 -5 1 3|). |
---|
| 352 | Note that any pictures not supplied in this list will be discarded and |
---|
| 353 | therefore not available as reference pictures later. |
---|
| 354 | |
---|
| 355 | \item[]\textbf{predict}: Defines the value of the syntax element |
---|
| 356 | inter_ref_pic_set_prediction_flag. A value of 0 indicates that the |
---|
| 357 | reference picture set is encoded without inter RPS prediction and the |
---|
| 358 | subsequent parameters deltaRIdx$-1$, deltaRPS, num_ref_idcs and |
---|
| 359 | Reference_idcs are ignored and do not need to be present. A value of 1 |
---|
| 360 | indicates that the reference picture set is encoded with inter |
---|
| 361 | prediction RPS using the subsequent parameters deltaRIdx$-1$, deltaRPS, |
---|
| 362 | num_ref_idcs and Reference_idcs in the line. A value of 2 indicates that |
---|
| 363 | the reference picture set is encoded with inter RPS but only the |
---|
| 364 | deltaRIdx$-1$ parameters is needed. The deltaRPS, num_ref_idcs and |
---|
| 365 | Reference_idcs values are automatically derived by the encoder based on |
---|
| 366 | the POC and refPic values of the current line and the RPS pointed to by |
---|
| 367 | the deltaRIdx$-1$ parameters. |
---|
| 368 | |
---|
| 369 | \item[]\textbf{deltaRIdx$-1$}: The difference between the index of the |
---|
| 370 | curent RPS and the predictor RPS minus 1. |
---|
| 371 | |
---|
| 372 | \item[]\textbf{deltaRPS}: The difference between the POC of the |
---|
| 373 | predictor RPS and POC the current RPS. |
---|
| 374 | |
---|
| 375 | \item[]\textbf{num_ref_idcs}: The number of ref_idcs to encode for the |
---|
| 376 | current RPS. The value is equal to the value of num_ref_pics of the |
---|
| 377 | predictor RPS plus 1. |
---|
| 378 | |
---|
| 379 | \item[]\textbf{reference_idcs}: A space-separated list of num_ref_idcs |
---|
| 380 | integers, specifying the ref idcs of the inter RPS prediction. The value |
---|
| 381 | of ref_idcs may be 0, 1 or 2 indicating that the reference picture is a |
---|
| 382 | reference picture used by the current picture, a reference picture used |
---|
| 383 | for future picture or not a reference picture anymore, respectively. The |
---|

| 385 | the predictor RPS. The last ref_idcs corresponds to the predictor |
---|
| 386 | picture. |
---|
| 387 | \end{itemize} |
---|
| 388 | |
---|
| 389 | For example, consider the coding structure of Figure~\ref{fig:gop-example}. |
---|
| 390 | This coding structure is of size 4. The pictures are listed in decoding |
---|
| 391 | order. Frame1 shall therefore describe picture with $\textrm{POC}=4$. It |
---|
| 392 | references picture 0, and therefore has $-4$ as a reference picture. |
---|
| 393 | Similarly, Frame2 has a POC of 2, and since it references pictures 0 and |
---|
| 394 | 4, its reference pictures are listed as \verb|-2 2|. Frame3 is a special |
---|
| 395 | case: even though it only references pictures with POC 0 and 2, it also |
---|
| 396 | needs to include the picture with POC 4, which must be kept in order to |
---|
| 397 | be used as a reference picture in the future. The reference picture list |
---|
| 398 | for Frame3 therefore becomes \verb|-1 1 3|. Frame4 has a POC of 3 and |
---|
| 399 | its list of reference pictures is \verb|-1 1|. |

---|
| 408 | Inter RPS prediction may be used for Frame2, Frame3 and Frame4, hence |
---|
| 409 | the predict parameter is set to 1 for these frames. Frame2 uses Frame1 |
---|
| 410 | as the predictor hence the deltaRIdx$-1$ is 0. Similarly for Frame3 and |
---|
| 411 | Frame4 which use Frame2 and Frame3 as predictors, respectively. The |
---|
| 412 | deltaRPS is equal to the POC of the predictor minus the POC of the |
---|
| 413 | current picture, therefore the deltaRPS for Frame2 is $4 -2 = 2$, for |
---|
| 414 | Frame3 is $2 - 1 = 1$ and for Frame4 is $1 - 3 = -2$. |
---|
| 415 | |
---|
| 416 | In Frame2, reference pictures with POC 0 and 2 are used, so the |
---|
| 417 | reference idcs for Frame2 are \verb|1 1| indicating that the reference |
---|
| 418 | picture, $-4$, in Frame1 is still a reference picture in Frame2 and |
---|
| 419 | Frame1 is also a reference picture in Frame2. The reference idcs for |
---|
| 420 | Frame3 are \verb|1 1 1|. The first and second “1”s indicating that |
---|
| 421 | the reference pictures "$-2$ $2$" in Frame2 are still reference pictures in |
---|
| 422 | Frame3 and the last “1” indicating that Frame2 is also a reference |
---|
| 423 | picture in Frame3. In Frame 4, the reference idcs are \verb|0 1 1 0|. |
---|
| 424 | The first “0” indicates that the reference pictures “-1” in Frame 3 is |
---|
| 425 | no longer a reference picture in Frame4. The next two “1”s indicate that |
---|
| 426 | the reference pictures “$1$ $3$” are now reference pictures of Frame4. |
---|
| 427 | The final “0” indicates that Frame3 is not a reference picture. |

| 2770 | \subsection{Using the decoder analyser} |
---|
| 2771 | If the decoder is compiled with the macro RExt__DECODER_DEBUG_BIT_STATISTICS defined as 1 (either externally, or by editing TypeDef.h), the decoder will gather fractional bit counts associated with the different syntax elements, producing a table of the number of bits per syntax element, and where appropriate, according to block size and colour component/channel. |
---|
| 2772 | The Linux makefile will compile both the analyser and standard version when the `all' or `everything' target is used (where the latter will also build high-bit-depth executables). |
