[theora-dev] FOSS Codecs for Online Video: Usability, Uptake and Development - First Draft
Dear Theora/Xiph folk, * FOSS Codecs for Online Video: Usability, Uptake and Development - First Draft* A review of available tools for the creation, playback and embedding of online video using Free and Open Source Software video codecs and a look at the most pressing areas for development to enhance their adoption by social change video projects on the web. http://wiki.transmission.cc/index.php/FOSS_Codecs_For_Online_Video:_Usability%2C_Uptake_and_Development I have been writing this report into FOSS Video Codecs for the last few months for the Transmission network of online video projects for social change. http://transmission.cc A version in PDF (see below) is also available for reading offline here: http://www.engagemedia.org/Members/anna/FOSS_Codecs_For_Online_Video_1_1.pdf I would rather have feedback into a second draft from the Transmission network before distributing the report too widely, to ensure the report benefits from all our knowledge and reflects the needs of the network. But I thought people on this list might like to take a look at the draft and let me know what is missing or pitch in with some different opinions. It is a set of practical recommendations for projects within our network and beyond, rather than an academic report. The recommendations cover codecs and containers, player and transcoding software, server-side transcoding, embedded playback, support of FOSS codecs in popular CMSs and the development of a transcoder/uploader client. The report PDF has some formatting errors and I'd prefer to distribute it in an open format - but I can't find a good solution for exporting from MediaWiki - please let me know if anyone has any ideas on this. Cheers, Anna http://EngageMedia.org http://Plumi.org

Hi Ken, Thanks for that :) I had heard of JMF but really not the FMJ project. Sounds very interesting, I'll take a look. I have added your notes to the wiki. There are a couple of places to add info - to the next version of the report or to the input page if you'd rather not have to format it / slot it in and I can do that for you. Version 1.2 of the document on the wiki here to be added to: http://wiki.transmission.cc/index.php/FOSS_Codecs_For_Online_Video:_Usability_Uptake_and_Development_1.2#Input Input page here for notes and additions: http://wiki.transmission.cc/index.php/FOSS_Codecs_For_Online_Video:_Input This is where I've copied your text - I'll let you know if we need further details in particular or feel free to post them there (as goes for anyone else).

That is totally awesome! It's not totally complete - I seem to be missing xine and the OggCodecs windows tools. But it is a pretty damned good report! Cheers, Silvia.

On the topic "Future of Web Video" You say: "Mobile devices often use hardware decoders rather than software decoders to playback video due to the relatively smaller capacity of the processor." "Ogg Theora/Vorbis does have the potential to be supported by mobile devices using the software decoder, but it remains to be seen what the degree of uptake of this will be." Actually, we are developing a Theora Hardware decoder solution aimed to mobile/embedded devices. The solution already works using our open source hardware design integrated with the LEON processor (an open source processor). We are capable to decode Theora streams in real-time (20 FPS) up to 600 Kbps running on an FPGA at 50 MHz. The video resolution is still very limited, but we are hard-working to improve the resolution using a different memory hierarchy in our hardware decoder. I believe that we will be able to decode high resolution video streams in the near future, with a complete open source hardware platform. The hardware theora source code are located on the Xiph SVN: http://svn.xiph.org/trunk/theora-fpga/theora_hardware/ Cheers, Felipe On 9/18/07, anna@engagemedia.org <anna@engagemedia.org> wrote:> Dear Theora/Xiph folk, > * > FOSS Codecs for Online Video: Usability, Uptake and Development - First > Draft* > A review of available tools for the creation, playback and embedding of > online video using Free and Open Source Software video codecs and a look > at the most pressing areas for development to enhance their adoption by > social change video projects on the web. > http://wiki.transmission.cc/index.php/FOSS_Codecs_For_Online_Video:_Usability%2C_Uptake_and_Development > > I have been writing this report into FOSS Video Codecs for the last few > months for the Transmission network of online video projects for social > change. > http://transmission.cc > > A version in PDF (see below) is also available for reading offline here: > http://www.engagemedia.org/Members/anna/FOSS_Codecs_For_Online_Video_1_1.pdf > > I would rather have feedback into a second draft from the Transmission > network before distributing the report too widely, to ensure the report > benefits from all our knowledge and reflects the needs of the network. > But I thought people on this list might like to take a look at the draft > and let me know what is missing or pitch in with some different > opinions.

Hi, Thanks everyone for your input on and offlist, I have included these as notes on our wiki and will develop some info on each area in the coming weeks.
