- SVC Reference Software (JSVM software) which focuses on functionality rather than performance. Most of the people use this for research purposes as the reference codec.
- The P2P-Next consortium provides its SVC software (encoder/decoder) as open source under LGPL which comprises an optimized version of the JSVM for both encoding and decoding.
- The Open SVC Decoder has been released recently - also under LGPL - and provides an alternative to the above mentioned implementations. Interestingly, it provides an integration for the Core Pocket Media Player (TCPMP) and Mplayer. Further information can be found on their Wiki.

Open Source Scalable Video Coding (SVC) Software
After DVB and ATSC announced to consider Scalable Video Coding (SVC) within their standards, I thought it would be interesting to blog about SVC software that is publicly available, especially because SVC has found its way already into video conferencing products (e.g., Vidyo, RADVISION, GIPS, SPIRIT DSP). Currently, I'm aware of the following open source SVC software:

Hi Christian,
Thanks for sharing this. You mentioned that P2P-Next provides the source code for their optimized implementation. Do you have a link for that? I can't find anything about this on their Web site.
Thanks..
Hi A!
I think you need to check the deliverables under the publications' section of http://www.p2p-next.org/. WP-4 deliverables provide the NextShare, the P2P engine based on tribler.org. WP-6 and WP-7 provide the PC and STB integration respectively.
Best regards,

Hello Cristian,
i wonder if you know of any progress in the open source software
in svc,
thanks and i hope you could respond as soon as possible.
Hi Anonymous,
currently, I'm not aware of any further SVC implementations that are (or will be) available to the public.
Cheers,

Hi Christian,
First, thank you for sharing this.
I wonder if there is another way to download latest version of the JSVM.
I am looking forward your response.
http://sites.google.com/site/pengjungwu/using-h-264-svc-reference-software--jsvm--on-macos is the only reference I've found so far...
thanks, however I have an XPOS, so what can I do?
thanks
I would suggest setting up a c/c++ environment and trying to compile the code on XPOS. However, I'm not sure that works on XPOS....
Dear Christian,
It seems great, really. SVC has great promise. Do you any software support SVC over TCP/IP.
I mean that SVC Video communication over IP because I have seen that RTP didn't support yet for SVC codec.
You recommendations are definetely appreciated
Thanks,
Here's the RTP Payload Format for SVC Video http://tools.ietf.org/html/draft-ietf-avt-rtp-svc-20 which is, I think, what you're looking for
Dear Christian,
thanks a lot for the links . I was not able to access the source code provided by the P2P-Next. Kindly advise.
i know the link below too gives SVC..

thanks.
Hi Christian,
Another Open Source SVC decoder implementation: Open SVC Decoder
Hi Christian,
Another Open Source SVC decoder implementation: Open SVC Decoder
@P2P-Next: I've updated the link, seems that p2p-next.eu is not working for the moment. Please search for deliverables under WP-6 which shall contain the SVC stuff.
Open SVC Decoder is mentioned, it's the last bullet in the list ;-) Thanks anyway for the comments!!!
Hi Christian Timmerer,
Thank you for the reply.
Your earlier post mentioned about the WP6 package.
Does it contain the optimized JSVM software? is the code in C++?
Thank you.
I think it's optimized JSVM written in C++ but you may check yourself
Hi,
I am unable to access the code for SVC encoder and decoder in the WP6.
Kindly advise.
thank you.
1. http://www.p2p-next.org/
2. "Publications"
3. "WP6"
4. Look for the deliverables you can find there for download.
I am trying to download jsvm. It says, first register and pay 0.99 dollars. It is not the question of the amount involved which is not much. But it is the method of payment. In a third world country, where we do not use credit cards, it becomes difficult to make payment. And we are deprived of download. Cant you make the download a little simpler.
Thanks.
Shiraz, the link for JSVM download points to a site which is not mine! This site provides download instructions using CVS and I'm not aware that CVS supports (micro-)payment. Thus, I don't know what you're talking about and I'm probably the wrong person to ask this question since I'm not maintaining/providing JSVM.
Christian,
Great list, thx for posting this resource.
cheers
Hi Christian,
i wonder if you have any idea if any of these implementation of svc has multi-thread features? Also, do they allow to control number of threads to be used? Thanks in advance.
Dear Christian Timmerer,
I have been trying to access the website of the "SVC Reference Software (JSVM software)", referred in your blog. Unfortunately, it seems that such material is no longer available at that address. Do you know where I can find it?
Best regards,
Nuno Roma
Hallo,
furthermore to what @Nuno said, the link to the reference software is definitely dead. However I could find the page archived. JVSM is stored on a CVS server, and the repository doesn't work ..
do you have any idea ?!
Sorry, but http://www.hhi.fraunhofer.de/en/departments/image-processing/image-video-coding/scalable-video-coding/svc-scalable-extension-of-h264avc/ points to the same link which seems to be broken. I will try to reach somebody from HHI to provide an update.
Concerning multithreading, I don't think that is optimized in this direction as usually reference software is concerned about functionality rather than performance.

hi,
I am new to multimedia transport, I am looking to transport individual layers of svc extracted from the jsvm software in a point to point communication. Do i need svc enabled streaming servers and decoders to do that? or existing players can work? (like packing the .264 files in container like mp4 and stream). IF i need svc enabled streaming and decoder players can you suggest any (preferably open source )?? please help me.
Thanks..
br,
boys21.
I downloaded JSVM software and builded the exe file.I modified the configuration files( encoder, layer 0 and layer 1 and placed them along with exe files in bin folder.I placed the input file also in the same folder.When i run the exe file of the encoder in command prompt , i am not getting the output file in bin folder. why ? whether the output file in some other folder ? please help me
Abhilash
ramu, yes, you need a special server for your use case but I'm not sure it is supported by open source tools as SVC is not supported there...
Abhilash, you need to contact the JSVM people, i.e. from where you've downloaded the software
Dear all,
I have not found P2P-NEXT source code yet. where can i find it?
Thank you in advance..
If it's not on the P2P-Next Web site, it's probably no longer there and won't come back as the project is over. Sorry for that ...
Dear christian,
i have a project in which i have to modify RTP in VLC so that it supports SVC files. Can you please help me with this?
i have very basic knowledge about this.
Well Ashish, I think it would be great if you could add SVC support to VLC but which codec did you have in mind? I think it depends a lot on the codec, not so much on the transport protocol....
Well, to be frank , I don't have much idea about codecs or transport protocols . I'm studying about it . What we have to do is that we have to add SVC support to RTP in VLC . As of now RTP cant transfer SVC videos in VLC. So if you could tell me where to start it would be great . Thanks
Hi Christian,
We need to add SVC support to H.264 while using RTP to stream videos in VLC. can you help me with this?
Anonymous, please contact me through some other channel, e.g., email. Thank you.
hi all, i am new in svc streaming .. i try to download the source code from JSVM repository but failed .. can any one tell me how to download different versions JSVM software..
thanks,
sibaji
Here is JSVM 9.17 you can download:

Hi All,
Actually, I am doing my researches on codec H.264/SVC under windows7 and I need to download the code source of codec H.264/SVC. But, I don't find the link which will allow me to do that. Really, it's so urgent to me. So, if anyway can help me, I will be so grateful to him/her..
Best regards
Hi,
the link above about the reference jsvm doesn't work:
http://ce.sharif.edu/courses/91-92/1/ce712-1/resources/root/kierank-jsvm-da983ce.zip
I don't known where is the problem :(,please, could you help me?
kind regards
@Anonymous: It works! or examine it step by step. First go to http://ce.sharif.edu then Courses part and then ...
Hi,
please please Milad, tell me exactly what kind of file should I find? Because, I am supposed to do some changes in the code, but, I don't find the files .hpp et .cpp. Also, each time I try to open my project, the visual studio ask me to do the conversion, really, I need your help,if you understand my problem.
kind regards
hi,
I'm having some doubts please clarify me...
how to get the network bandwidth and how to insert our own algorithm in the open svc decoder or whether it is possible to insert our own algorithm in open svc decoder
@Amal You are talking about JSVM software? explain more about what you want to change? the files' name in JSVM usually illustrates its function.
The conversion message is because of the version of your project does not conform to the version of VS. I think it is possible to build JSVM with VS v8, 9 or 10.
Hi, @Milad,
I will explain to you :).In fact, I had to download the open source JSVM software. I want to be able to change some parameters and do my own configuration (Number of pictures in the GOP, the number of resoltion layers...) to obtain the desired results.
Thanks in advance
Hi all,
I have downloaded the JSVM software, but, I couldn't open it as a project under visual studio. Because, I have to be able to access the code source,modify it then compile it.
I want to test something urgent in my research.
please could you help me?Really, I am blocked
I will be grateful for you.
Best regards
hello sir ....i have to use the jsvm software ....for my project to trnsmi a stefan video sequence hw will i use it
Hi all
any one help me to download current and stable version of JSVM software
I found it but its not work properly
thanks
Dear christian,
What are the changes to be made in the encoder configuration file of JSVM to get a better/same psnr with REDUCED bit rate in the video sequence, for a rate controller in h.264 encoder, kindly help i am looking forward your response
