We offer our Scalable Video Coding (SVC) dataset for Dynamic Adaptive Streaming over HTTP (DASH),
including the MPD files and
SVC Sequences
under the following locations:
Quick Links
In SVC, a video is split into multiple interdependent layers at varying qualities. The base
layer (BL) is the layer which all other layers depend on, though enhancement layers (EL) can also
depend on other enhancement layers.
The following three encoding variants, each offering several layers/representations, are available
(the target video bitrates listed are the cumulative bitrates for SVC):
- 3 Representations in Variant I (3 BL + 9 EL) - [Config]:
- 640x360: 600 kbps (BL), 990 kbps (EL 1), 1500 kbps (EL 2), 2075 kbps (EL 3)
- 1280x720: 1500 kbps (BL), 2750 kbps (EL 1), 4800 kbps (EL 2), 7800 kbps (EL 3)
- 1920x1080: 4000 kbps (BL), 5500 kbps (EL 1), 7200 kbps (EL 2), 10400 kbps (EL 3)
- 3 Representations in Variant II (3 BL + 6 EL) - [Config]:
- 480x360: 180 kbps (BL), 242 kbps (EL 1), 444 kbps (EL 2)
- 1280x720: 780 kbps (BL), 1100 kbps (EL 1), 1800 kbps (EL 2)
- 1920x1080: 2000 kbps (BL), 3190 kbps (EL 1), 5040 kbps (EL 3)
- 1 Representation in Variant III (1 BL + 3 EL) - [Config]:
- 640x360: 600 kbps (BL)
- 1280x720: 2200 kbps (EL 1)
- 1920x1080: 4800 kbps (EL 2), 10400 kbps (EL 3)
- 1 Representation in Variant IV (1 BL + 4 EL) - [Config]:
- 640x360: 600 kbps (BL)
- 1280x720: 2200 kbps (EL 1)
- 1920x1080: 4800 kbps (EL 2), 6760 kbps (EL 3), 11200 kbps (EL 4)
In addition, all representations are available with temporal scalability (6, 12 and 24 FPS).
The target video bitrates were only approximated, unfortunately they are not always met due to
restrictions of the encoder.
We used a segment size of 48 frames (2 seconds at 24 fps).
The following videos are part of our dataset:
| Name and Source |
Length |
Variant I (360p/720p/1080p) |
Variant II (480x360/720p/1080p) |
Variant III (spatial+quality) |

Config Files
Config files for Variants I, II and III are provided for both, MainConcept and JSVM: [Config]. Config files for Variant III are provided only for MainConcept.
We used the MainConcept SVC encoder in Variable Bitrate Mode, therefore allowing us to target very specific bitrates (see Variants I,II and III above). Unfortunately, the JSVM Reference Encoding Software does not support Variable Bitrate Mode, nor more than 3 layers (hence we omit config files for Variant IV), therefore configuration files provided for JSVM do not offer appropriate bitrate settings and are only for experimental purpose.
It is not necessary, but recommended to downscale the YUV videos to the appropriate resolutions before encoding them, for both, MainConcept and JSVM.

Pseudo Signal-to-Noise-Ratios (PSNR) and Structural Similarity (SSIM) values were calculated using the open source available psnr tool of libyuv.
The PSNR/SSIM values were calculated per layer per frame for Variants I, II and III (@ 24 fps). They are available for Big Buck Bunny, Elephants Dream and Tears of Steel.

For decoding, we recommend using the JSVM Reference Software, which includes the H264AVCDecoderLibTestStatic tool. The usage is as follows:
H264AVCDecoderLibTestStatic SvcFile.264 SvcOutFile.yuv
Example:
# download H.264/SVC file
wget http://concert.itec.aau.at/SVCDataset/svcseqs/I/BBB-I-360p.264
# extract the base layer and all 3 enhancement layers (the 3rd EL is the actual file)
BitStreamExtractorStatic BBB-I-360p.264 BBB-I-360p-L0.264 -l 0
BitStreamExtractorStatic BBB-I-360p.264 BBB-I-360p-L1.264 -l 1
BitStreamExtractorStatic BBB-I-360p.264 BBB-I-360p-L2.264 -l 2
# decode all layers
H264AVCDecoderLibTestStatic BBB-I-360p-L0.264 BBB-I-360p-L0.yuv
H264AVCDecoderLibTestStatic BBB-I-360p-L1.264 BBB-I-360p-L1.yuv
H264AVCDecoderLibTestStatic BBB-I-360p-L2.264 BBB-I-360p-L2.yuv
H264AVCDecoderLibTestStatic BBB-I-360p.264 BBB-I-360p-L3.yuv
We provide a toolchain at our github repository (
DASH SVC Toolchain @ Github), which includes the python script
svc_merge.py, which has the following purpose:
Given the init-file (init segment), the base layer of segment $x$ and multiple enhancement layers of segment $x$ in the right order, it creates a decodeable H.264/SVC segment, which can be decoded with
H264AVCDecoderLibTestStatic.
DASH SVC Toolchain @ Github
By using JSVMs BitStreamExtractorStatic tool with the given H.264/SVC Bitstream, you can extract the following information from the SVC sequences (e.g., for BBB):
Note: JSVM calculates the resolution wrong and sometimes displays +8 more than it should (e.g., 368 means 360, 1088 means 1080). Bitrate information is incorrect as-well.
