Slashdot Mirror

mrcgran asks: "I have been trying to find the best solution to transfer VHS tapes to a digital format using Free Software only. I would like to lose as little as possible in the conversion, sampling optimally, minimizing noise and being in control of every step of the process. Storage is not a problem. I'm expecting to use around 5GB+ for each hour of raw captured footage." If you were going to build a VHS capture system using Free Software, how would you do it?

The software part seems promising: VLC and mencoder for conversion of raw footage, Cinelerra and many others for video editing.

However, the hardware is being tricky. Most try to bloat the device adding functions like TV/compression/edition instead of focusing on the raw A/D conversion. Chipsets are hidden, and parameters like signal-to-noise, sampling rate etc are unavailable for comparison. Information is scattered and very difficult to find.

Which chipsets/products should I look for, specially for use with Linux and BSD? Which ones allow oversampling of pixel resolution and number of frames (in order to average the values and reduce the noise)? Which setup should I use: S-Video/Composite, sampling rate/oversampling, suggestions on high-quality VHS players/heads/tape cleaning processes, etc? Has anyone tried to use scaling algorithms such as hq/scalenx to upscale video and sound resolution? Pitfalls?"

h2g2bob writes "VideoLAN yesterday released a new version of VLC media player. A shout out goes to ffmpeg for many of the codec improvements." From the blurb: "Building on feedback from the 29 million downloads of VLC media player 0.8.5, we bring you version 0.8.6 with many bugfixes, as well as a couple of new features we think you will truly enjoy. Most prominent are probably Windows Media Video 9 and Flash Video. Other important changes are improved H.264 decoding, better Windows Unicode support, a Fullscreen controller, and Apple Remote support for Mac OS X."

CaptScarlet22 writes " VideoLAN is seriously threatened by software patents due to the numerous patented techniques it implements and uses. Also threatened are the many libraries and projects which VLC is built upon, like FFmpeg, and the other fellow Free And Open Source software multimedia players, which include MPlayer, xine, Freevo, MythTV, gstreamer."

ccdotnet asks: "I look after a small web site for a rising sports star. We have a small number of short videos in .WMV (9) format available for download. These .WMV files are typically 3-5 MB in size (we do a "low res" and a "hi res" version). Each video is typically 1-2 minutes and 320x240. The site gets maybe 100 visitors per day. Our outbound hosting bandwidth is _very_ limited, so although we are keen to cater for non-Windows users (around 7% of our visitors), I've struggled to find a suitable video format which doesn't blow the size of the file right out. Ideally I would like to keep these files at a similar size but at the same time want to maintain a reasonable video quality. Are users of other platforms just out of luck? What non-Windows/Mac video formats can people recommend so that I can deliver this content to people who can't play .WMV for one reason or another?" A few years ago, playing .WMV files might have been problematic for users who didn't use either a Macintosh or a Windows-based operating system. Now, with MPlayer and its derivatives making strides, it's not as much of an issue. Of course, there are still .WMV files that don't play well in Mplayer, but what suggestions would you have for creating Mplayer-safe .WMVs as well as other, more cross-platform friendly formats?

Ravalox writes "AA Helper Library, which is a set of libraries to assist in the development of AA-Lib games/applications, has made its initial release. It currently provides a few graphics primitives and a render-to-frame function so you can get a normal image out of AA-Lib. If like me you are an ascii video fan another helpful ascii library is libcaca which is currently supported in Video Lan Media Player and Mplayer."

p80 writes "The Xiph foundation announced today that the 'Theora I bistream format is now frozen,' even though Beta 1 is not out yet and encourage people to try it as 'there's no reason to delay adopting a free alternative any more!' Mplayer and Xine both support Theora. For Windows users, Directshow filters for Ogg Vorbis, Speex, Theora and FLAC are available here. You can get test cases here and transcode Quicktime movies to theora on that page." This freeze, as an anonymous reader puts it, "means that all future versions will support the format as it is now. It will be interesting to see if there is as much uptake for this as there was for the Vorbis sound format."

Snaller writes "Recently, MPlayer claimed that KISS Technology were violating the GPL by using parts of their MPlayer movie playback code in proprietary software. Now The Danish National Radio has interviewed the managing director of Kiss Technology, Peter Wilmar Christensen. He denies all claims of wrongdoing and suggests that if the pieces of code are the same, perhaps they were leaked from Kiss Technology and were then used by the Mplayer group. He also adds that the GPL is a weak license which has never been tested in court. Gabucino from the Mplayer team is furious, and accuses the director of outright lying."

bfree writes "Not for the first time, the people at MPlayer think they have found their code being distributed binary only, this time in at least one of KISS Techologies products. In their traditional quiet style the full story is now the first piece of news on their homepage including string comparisons between the player ROM and MPlayer. The 'evidence' presented relates to subtitle identification, where the KISS ROM includes the same list, in order, of subtitle formats as MPlayer (including their own format mpsub) and MPlayer's patterns for each of the formats are also there identically."

altaic asks: "Today I was looking for a container format to store my anime collection (multi-language audio and subs), and I discovered popular media containers actually suck. AVIs are a hacked mess and don't even support multiple audio tracks. OGMs are catching on, but they don't have an index, nor do they support variable framerates (the fps value is stored in the header). I found some info on the Matroska container, which looks really cool (it supports multiple subtitle streams, multiple audio streams, a slew of other nice features), as well as the very young MPCF (mplayer container format). I'd really like to hear about other people's experiences with newer, more useful media containers."

bfree writes "Now on your favourite mplayer mirror you can find the 1.0Pre1 release of Mplayer! While work is underway on a second-generation version of Mplayer, I have already fired off emails to my Windows-based friends to let them now that the one player to rule them all now has (preview) support for their OS (I've only looked at a precompiled command line version on Windows but it handled everything I threw at it so far except DVDs). Big changes include Windows (via mingw32 and cygwin) ports, as well as Mac OS X (with extra-accurate Darwin timers). Now if only all those legal questions would go away, perhaps we could have a new killer Free Software application to save people installing Real, Quicktime and Windows Media Player (on Linux!?) or perhaps it's the one application to finally tell the **AA where the world wants to go today!"

An anonymous reader writes "Following on from the recent spate of reverse engineering articles, there is an interesting summary of the reverse engineering of a binary only Linux driver. The driver is for the integrated MPEG decoder on VIA's popular EPIA-M boards. At the moment VIA has not publicly released the source code for the MPEG chipset on these boards and will only make the code available under NDA saying that "Typically, only requests from companies developing product for sale will be approved." As a result this is holding back development of open source tools (e.g. xine, mplayer, vdr) that would be able to make use of the interesting hardware on these boards."

Viqsi writes "459 days after the previous stable release, the MPlayer folks have finally released stable version 0.90. With this done, A'rpi (th head maintainer) is leaving the project, citing too-much-free-time-forever-lost issues, and the team is looking closely at revising the way the project is managed as a result. Here's hoping some improvements come out of this."

why-not-now asks: "Recently there's been a lot of talk about open source/free software that enables your PC to act as a DVR, all-purpose media player, DVD player, CD player, MP3 player, etc... not to mention the ability to play all sorts of video games (if you know where to look). The idea of the set top MAME console is nice, but with a little TV/Audio out, a little know how and the right software, are we currently able to put together a free version of the big convergence media center others are trying to do?"

Slashback with words on the demise of TIPS, MPlayer's newest add-in, Revolution OS on DVD, Wal-Mart blinking first in their fight with FatWallet, and more. Read on for the details.

Facts is facts, Ma'am. joebeone writes "WalMart has backed down [AScribe.org] from it's DMCA claim in the FatWallet case[1] after FatWallet countered that facts are uncopyrightable (at least in the US). Let this be a lesson to those who would use the DMCA to unjustly intimidate websites into removing content. I definitely think that Boalt Hall's Samuelson Law, Technology and Public Policy Clinic deserves some major credit for sticking up for the little guys who don't have the litigatory resources that companies like WalMart have.

[1] WalMart claimed that their day-after-thanksgiving sale prices were copyrightable."

Maybe they just changed the drop location. An anonymous reader writes "There was one small ray of light in the Homeland Security Act. A provision inserted in the bill killed the Justice Department's TIPS initiative. You'll recall that TIPS was the DoJ's proposal to create a domestic spy network using ordinary citizens. And I was hoping to join up and inform them that John Ashcroft wears women's underwear. Oh well ..."

Best way to play back "L.A. Confidential." An anonymous reader writes "The best media player for *nixes, MPlayer, has just gotten better with the ability to play Windows Media Player 9 (WMV9 and WMA9) files. When Sorensen playback was added the only remaining codecs were the Window Media Player ones. Now that this is complete, Linux finally seems to have a complete solution for multimedia playback. It just remains for the mainstream distros to include this gem."

Measure three or four times at least, cut once. jdevons writes "The Owner-Builder Book that I reviewed a while ago has been updated. The author reads slashdot regularly and included many of the ideas and suggestions offered in the slashdot comments ..."

Jeff, Rob and Chris in their Hollywood makeup. updog writes "The film Revolution OS, which has been discussed on Slashdot here and here, is now available on DVD at Netflix (btw, it's interesting to note that this Netflix version is sub-licensed under the guise of pay-per-view television, and the director J.T.S. Moore wasn't even aware of its existence until recently.)

A 2 Disc Special Edition DVD will be available in January 2003, and will include additional interviews, bonus material, and better video quality over the Netflix version. You can make sure that you're notified when it's released by requesting info here. Finally, I've written a review of the Netflix version of the DVD, which you can read here."

Next year's stocking stuffer, maybe? An anonymous reader writes "nvmax.com is running a story/press release explaining how Dynamism.com is teaming up with the Zaurus Open Source development community to bring the Sharp Zaurus SL-C700 to English!. I need to get one!"

What I want is C-64 style Aztec. retro128 writes "For all of your old schoolers out there, Tierra Entertainment has released a re-make of King's Quest II, which includes original art, completely redone music, and a few extra things not seen in the original game (some early screen shots hinted at a town, which did not exist in the original). What's remarkable is that Tierra has no affiliation with Sierra whatsoever, and is driven by two developers who wish to remain anonymous. I've played their re-make of KQ1 and it's up to snuff. Check out the main page or go straight to the good stuff."

Slashback with news on ATI drivers for non-ATI branded cards, the viewer-led movement to save Farscape, wearable computing from MIT, text-to-facial-expression software, and more. Read on for the details

Maybe customer service isn't dead. On November 28th, we posted a report that OEM cards using ATI chips had trouble with the official drivers from ATI. Terry Makedon (Senior Product Manager, Software for ATI Technologies) writes "Last week we posted a set of unified Linux drivers. These drivers were only loading up on 'Built by ATI' cards. Through our various feedback mechanisms we have determined that there is a large community of 'Powered by ATI' Linux users that did not benefit from our Linux drivers. At this point we are happy to announce an update to our Linux driver (ver. 2.5.1) which will work on both 'Powered by' and 'Built by.' ATI's driver and software strategy is firmly based on responsiveness and we greatly appreciate the feedback our Linux users have provided. Please use http://apps.ati.com/linuxDfeedback/ for a direct feedback line to ATI.

Thanks again for the feedback."

But what if we put the show into this Interdimensional Fungubulon, and then jumped through this here "wormhole"? xagon7 writes "David Kemper, the producer/writer of Farscape, mentioned that it would be theoretically and legally possible for a group to set up a non-profit organization for fans to donate money to, in order to finance an episode and make Farscape all that much tastier to Sci-Fi for the 5th season. They have done just that. They have $200,000 worth of pledges and only need $800,000 total....I hope this gets Slashdotted. Read the story here and you can pledge here."

You're getting less happy to see me? man_of_mr_e writes "Check out MIThril, the next generation research platform for context aware wearable computing. It's been about 18 months since this was last talked about here on Slashdot, and it's kind of cool to see how far the technology has come since then. For those that aren't aware of what it is, it's essentially a project to prototype human wearable computers, complete with schematics, pictures, and a cvs repository for software. Now you too can be like that guy in the IBM commercials trading stock while feeding the pigeons."

Flattening the slope to entry. Catskul writes "You don't need the libwine hack, mentioned in the previous news entry. Just follow the New QT Howto, download the codecs and start MPlayer."

Don't look at me in that tone of voice! 1010011010 writes "On Nov. 26, you ran a story on SpeechView, 'software that translates the voice on the other side of the line into a three dimensional animated face on the computer.' The North Carolina State University Department of Computer Science's 'Voice IO Group' is also working on that problem. Their software looks like it might be better. Read about it here. Includes quicktime movies of the results."

Victory, or a reprieve? A non moose cow writes "Just noticed that a couple of my favorite "Killed by the RIAA" webcast stations are back... like Soma-FM and Monkey Radio (get the streams at Shoutcast). The saving grace came via the recent passage of HR5469 [PDF] by the US Legislature. Thank you to all that sent letters and/or money to fix this problem. If you have been yearning for the resurrection of your favorite stream, go check, it might be back. If you would like to trace the chronology of this mess, check out the Soma-FM news page."

Tonight's Slashback includes updates on the state of MPlayer, Google's API release, DIY backyard transportation, and (thanks to politech) the "hidden camera" bill. Oh, and apparently, Mars is not the lush, green paradise you thought it might be. Read on for the details.

But what about the nude Russian girls who apparently need me? happyclam writes: "The text of the "hidden camera" bill has been posted at politechbot.com. Although we have already beat this one to death, I found the actual bill worth reading. One thing that had not been mentioned is that it allows for civil and criminal liability for spammers who email sexual advertisements without proper markings. Although I still prefer positive labeling (e.g. "kid-safe(tm)") to negative labeling (e.g. "socially questionable"), this bill does, I think, have a few good points to it. Read it."

DVDs want to be free. An Anonymous Coward writes: "According to this email and the latest news the mplayer source code is finally 100% GPL compliant.

Several people have submitted stories about the author of Mplayer accusing Warpvision of, err, "borrowing" their code for Warpvision's OS/2 player. I have two reactions - one, someone still uses OS/2? And two, something about imitation being the sincerest form of flattery...Update from CD: Hold on there, everyone. I downloaded the WarpVision source and lo and behold the GPL is there in all its free software glory. I think Mplayer spoke too soon, too rashly, or alternatively, WarpVision was just too slow to update thier site. I'd love to hear both sides of this before we all freak out. Further Info: It was pointed out to me (CD) that the MPlayer program itself is not Open Source software (it calls itself Basically GPL, which, BTW, hasn't been approved by the OSI), so in the end this might just be proprietary software piracy. (Yawn)
