Wednesday, February 25. 2009Camp KDE videos: Come and get 'emAfter a month's delay, they're done. In the interim (after the delays mentioned in my last post on this topic), my poor, underpowered desktop machine has endured transcode after transcode (from the original source material) and my Internet connection upload after upload as I tried to figure out just why Blip.tv wouldn't work with X or Y. (In fact, I can quantify these: X is Vorbis/Theora, which produced awful audio and very desynchronized audio/video upon their conversion to .flv; Y is a lot of things related to the original anamorphic encoding of the videos, which Blip.tv can't handle, and finding the right combination of settings and flags and adjustements to make the aspect ratios come out so that everyone didn't look like Gumby®.) This was followed by a few days of uploading; Blip seems to max out uploading speeds somewhere between 100kbit and 200kbit, so uploading almost 6GB of data, one chunk at a time, took a bit. The end result is thirteen videos, each Xvid-encoded (at least it's OSS, although patent-encumbered...see Vorbis/Theora problems above) with a Matroska container. You can get to them through my show or to individual videos directly (these might not be in strict as-presented order): Enjoy!Trackbacks

Thanks for the videos. I just watched the CMake/CTest/CPack talk and it was very interesting. The audience seemed a bit tired though. Perhaps it was too hot over there?
I was looking for these videos again and here they are.... Thanks a lot! This will give a good bed time "reading".

Who gives a darn? We want the downloadable ogv, we couldn't care less about the FLV crap.
To elaborate on that: patent-encumbered video codecs suck, and those files don't play at all on many popular GNU/Linux distributions (nor does Flash/FLV for that matter). Please upload the ogv files too, even if they don't convert properly.
You're the first person to tell me that opinion; everyone else I've talked to before uploading the Xvid versions said they didn't care.
Feel free to download the Xvid ones and convert them if you want to watch them offline and care about the format.
Then you didn't talk to the right people (who actually care about freedom).
Who cares about the crappy proprietary FLVs? Sacrificing freedom (using encumbered codecs) for the sake of those is really counterproductive.
You clearly haven't read my earlier post that was linked above, or even this one carefully.
1) Kdenlive has a known problem exporting to Theora/Vorbis, which is why they were in Xvid/MP3 in the first place 2) Transcoding to Theora/Vorbis after the fact was giving me horrible audio quality, even though it shouldn't have been an issue...maybe it was my version of encoder or something, but who knows 3) In addition to 2), blip.tv wasn't correctly transcoding to flv from Theora/Vorbis, plus was also having horrible audio quality problems In short, someone else is welcome to transcode these, but as I have spent a month working on them and don't have more time to spend trying to figure out WTF is up with transcoding to Theora/Vorbis, I will not be doing so.
Oh, and the people who cannot watch Xvid or FLV obviously also cannot convert it, you need a decoder for both.
 Aw, my dearest illogic-al. Thank you for taking the time to read my "blog-post".
thanks for your work! it's much appreciated, even for people who care about freedom and are not satisfied with the proprietary formats. there's no perfect world, there's no pure way.
i loved to watch those very interesting videos! |
