1 General Information

Reference software is being made available to provide a reference implementation of the draft HEVC

standard being developed by the Joint Collaborative Team on Video Coding (JCT-VC) regrouping experts

1 Date saved: 2013-04-23

from ITU-T SG 16 and ISO/IEC SC29 WG11. One of the main goals of the reference software is to

provide a basis upon which to conduct experiments in order to determine which coding tools provide

desired coding performance. It is not meant to be a particularly efﬁcient implementation of anything,

and one may notice its apparent unsuitability for a particular use. It should not be construed to be a

reﬂection of how complex a production-quality implementation of a future HEVC standard would be.

This document aims to provide guidance on the usage of the reference software. It is widely suspected

to be incomplete and suggestions for improvements are welcome. Such suggestions and general in-

quiries may be sent to the general JCT-VC email reﬂector on jct-vc@lists.rwth-aachen.de

(registration required).

3 Using the encoder

TAppEncoder [-h] [-c config.cfg] [--parameter=value]

Option Description

-h Prints parameter usage.

-c Deﬁnes conﬁguration ﬁle to use. Multiple conﬁguration ﬁles

may be used with repeated –c options.

--parameter=value Assigns value to a given parameter as further described below.

Some parameters are also supported by shorthand “–opt value”.

Sample conﬁguration ﬁles are provided in the cfg/ folder.

3.1 GOP structure table

Deﬁnes the cyclic GOP structure that will be used repeatedly throughout the sequence. The table should

contain GOPSize lines, named Frame1, Frame2, etc. The frames are listed in decoding order, so Frame1

is the ﬁrst frame in decoding order, Frame2 is the second and so on. Among other things, the table

speciﬁes all reference pictures kept by the decoder for each frame. This includes pictures that are used

for reference for the current picture as well as pictures that will be used for reference in the future. The

encoder will not automatically calculate what pictures that has to be kept for future references, they

have to be speciﬁed. Note that some speciﬁed reference frames for pictures encoded in the very ﬁrst

GOP after an IDR frame might not be available. This is handled automatically by the encoder, so the

reference pictures can be given in the GOP structure table as if there were inﬁnitely many identical GOPs

before the current one. Each line in the table contains the parameters used for the corresponding frame,

separated by whitespace:

Type: Slice type, can be either I, P or B.

2 Date saved: 2013-04-23

POC: Display order of the frame within a GOP, ranging from 1 to GOPSize.

QPOffset: QP offset is added to the QP parameter to set the ﬁnal QP value to use for this frame.

QPFactor: Weight used during rate distortion optimization. Higher values mean lower quality

and less bits. Typical range is between 0.3 and 1.

tcOffsetDiv2: In-loop deblocking ﬁlter parameter tcOffsetDiv2 is added to the base parameter

LoopFilterTcOffset div2 to set the ﬁnal tc offset div2 parameter for this picture signalled in the

slice segment header. The ﬁnal value of tc offset div2 shall be an integer number in the range

−6..6.

betaOffsetDiv2: In-loop deblocking ﬁlter parameter betaOffsetDiv2 is added to the base parame-

ter LoopFilterBetaOffset div2 to set the ﬁnal beta offset div2 parameter for this picture signalled

in the slice segment header. The ﬁnal value of beta offset div2 shall be an integer number in the

range −6..6.

temporal id: Temporal layer of the frame. A frame cannot predict from a frame with a higher

temporal id. If a frame with higher temporal IDs is listed among a frame’s reference pictures, it is

not used, but is kept for possible use in future frames.

num ref pics active: Size of reference picture lists L0 and L1, indicating how many reference

pictures in each direction that are used during coding.

num ref pics: The number of reference pictures kept for this frame. This includes pictures that

are used for reference for the current picture as well as pictures that will be used for reference in

the future.

reference pictures: A space-separated list of num ref pics integers, specifying the POC of the

reference pictures kept, relative the POC of the current frame. The picture list shall be ordered,

ﬁrst with negative numbers from largest to smallest, followed by positive numbers from smallest

to largest (e.g. -1 -3 -5 1 3). Note that any pictures not supplied in this list will be discarded

and therefore not available as reference pictures later.

predict: Deﬁnes the value of the syntax element inter ref pic set prediction ﬂag. A value of 0

indicates that the reference picture set is encoded without inter RPS prediction and the subsequent

parameters deltaRIdx−1, deltaRPS, num ref idcs and Reference idcs are ignored and do not need

to be present. A value of 1 indicates that the reference picture set is encoded with inter prediction

RPS using the subsequent parameters deltaRIdx−1, deltaRPS, num ref idcs and Reference idcs

in the line. A value of 2 indicates that the reference picture set is encoded with inter RPS but only

the deltaRIdx−1 parameters is needed. The deltaRPS, num ref idcs and Reference idcs values

are automatically derived by the encoder based on the POC and refPic values of the current line

and the RPS pointed to by the deltaRIdx−1 parameters.

deltaRIdx−1: The difference between the index of the curent RPS and the predictor RPS minus

deltaRPS: The difference between the POC of the predictor RPS and POC the current RPS.

num ref idcs: The number of ref idcs to encode for the current RPS. The value is equal to the

value of num ref pics of the predictor RPS plus 1.

reference idcs: A space-separated list of num ref idcs integers, specifying the ref idcs of the inter

RPS prediction. The value of ref idcs may be 0, 1 or 2 indicating that the reference picture is

a reference picture used by the current picture, a reference picture used for future picture or not

a reference picture anymore, respectively. The ﬁrst num ref pics of ref idcs correspond to the

Reference pictures in the predictor RPS. The last ref idcs corresponds to the predictor picture.

For example, consider the coding structure of Figure 1. This coding structure is of size 4. The pictures

are listed in decoding order. Frame1 shall therefore describe picture with POC = 4. It references picture

0, and therefore has −4 as a reference picture. Similarly, Frame2 has a POC of 2, and since it references

pictures 0 and 4, its reference pictures are listed as -2 2. Frame3 is a special case: even though it

only references pictures with POC 0 and 2, it also needs to include the picture with POC 4, which must

be kept in order to be used as a reference picture in the future. The reference picture list for Frame3

therefore becomes -1 1 3. Frame4 has a POC of 3 and its list of reference pictures is -1 1.

Decode Order

Inter RPS prediction may be used for Frame2, Frame3 and Frame4, hence the predict parameter is set

to 1 for these frames. Frame2 uses Frame1 as the predictor hence the deltaRIdx−1 is 0. Similarly for

Frame3 and Frame4 which use Frame2 and Frame3 as predictors, respectively. The deltaRPS is equal

to the POC of the predictor minus the POC of the current picture, therefore the deltaRPS for Frame2 is

4 − 2 = 2, for Frame3 is 2 − 1 = 1 and for Frame4 is 1 − 3 = −2.

In Frame2, reference pictures with POC 0 and 2 are used, so the reference idcs for Frame2 are 1 1

indicating that the reference picture, −4, in Frame1 is still a reference picture in Frame2 and Frame1

is also a reference picture in Frame2. The reference idcs for Frame3 are 1 1 1. The ﬁrst and second

1s indicating that the reference pictures “−2 2” in Frame2 are still reference pictures in Frame3 and the

last 1 indicating that Frame2 is also a reference picture in Frame3. In Frame 4, the reference idcs are

0 1 1 0. The ﬁrst 0 indicates that the reference pictures -1 in Frame 3 is no longer a reference picture

in Frame4. The next two 1s indicate that the reference pictures 1 3 are now reference pictures of Frame4.

The ﬁnal 0 indicates that Frame3 is not a reference picture.

In order to specify this to the encoder, the parameters in Table 2 could be used.

Here, the frames used for prediction have been given higher quality by assigning a lower QP offset.

Also, the non-reference frames have been marked as belonging to a higher temporal layer, to make it

possible to decode only every other frame. Note: each line should contain information for one frame, so

this conﬁguration would be speciﬁed as:

Frame1: P 4 1 0.5 0 0 0 1 1 -4 0

Frame2: B 2 2 0.5 1 0 1 1 2 -2 2 1 0 2 2 1 1

Frame4: B 3 3 0.5 2 0 2 1 2 -1 1 1 0 -2 4 0 1 1 0

The values of deltaRIdx−1, deltaRPS, num ref idcs and reference idcs of FrameK can be derived from

the POC value of Frame

and the POC, num ref pics and reference pictures values of Frame

, where

K is the index of the RPS to be inter coded and the M is the index of the reference RPS, as follows.

deltaRIdx

− 1 ← K − M − 1 ;

deltaRPS

← POC

− POC

;

num ref idcs

← num ref pics

+ 1 ;

for j ← 0 to num ref pics

for i ← 0 to num ref idcs

if reference pictures

then

if reference pictures

;

else reference idcs

K,j

= 2 ;

else

reference idcs

[j] = 0 ;

end

reference pictures

M,num ref pics

does not exist and is assumed to

be 0

Note: The above (automatic) generation of the inter RPS parameter values has been integrated into the

encoder, and is activated by the value of predict = 2 followed by the value of deltaRIdx−1, only, as

described above.
