A1 & Parallel Zip

Posted on: 2009/4/19 10:15 #281

Not too shy to talk

Hi,
I recently acquired a 2nd-hand parallel Zip 100, and thought it might be useful for using with my A1 (I have a scsi internal Zip in my A1200T, and Zip disk might be easier to transfer files than CD).

However, I can't seem to get the A1 to recognise the drive. I tried the ZIP dos driver that comes with OS 4.0, changed the device to a1parallel.device and the unit to 0, but I can't mount the device. In U-Boots prefs, the Parallel Port is set to EPP and address 0x378.

Does anyone have any suggestions?

Thanks.

Re: Backing up DVD's with SAM?

@Astral

Thanks! Just tried the first method specified (PeeVOBill -> mkisofs -> AmiDVD) and it worked just fine. Mkisofs threw up some errors (complained that the specified directory couldn't be found), but created the image anyway. It was called CDROM by default, but I see on the man page that there's an option -V to specify a volume name. Still played in my DVD player and DVDPlayer worked as well.

I don't think the direct copy method would work with CSS encrypted DVDs. I think you'd need PeeVOBill to copy them to your HD first.

Re: DVDs, AVIs, and video work on the A1

Thanks everybody, I seem to have made a major breakthrough!

I've discovered that it was DVD+Rs that were giving me the problem. I can rip OK from DVD-Rs. I can also rip from DVD+RWs, but it's problematic: if I record more than one programme on a disc, FFMpeg can only "see" part of each one. Again, the disc plays fine, it's FFMpeg that has the difficulty.

I wonder if my Asus DVD drive is not 100% compatible with the +R format? Or maybe it's FFMpeg that's incompatible? Can someone have a go and let me know the results?

Thanks.

I'm a little confused, are you taking about the physical DVD? Or are you taking about the file format? If you are taking about the physical DVD then copy across the files first or try a different DVD medium. If you are taking about the file format then check to see if you can't change how your DVD recorder records its recording. eg My DVD recorder can record audio in PCM (default) or Mp3 (needs to be selected) The video is always MPeg.

Or maybe I am way off the track and therefore, do not worry

The file format. I have tried copying the .VOB files across with PeeVOBill, and while DVPlayer can play them FFMpeg cannot read the video stream.

As already mentioned if your using ffmpegGUI then you need to set the audio codec to "Copy". Our version of ffmpeg doesn't seem to be able to read the DVD's audio files.

To reduce the file size significantly you can try the following using the following setting in ffmpegGUI.

Load the DVD(pal) or DVD(ntsc) settings from the Quick Setup menu.

Set the video bitrate to "2040k". (SVCD quality)
Set the audio codec to "Copy".
Set the "Duration" to 20 sec. (for testing)
Set the input and output filenames.
Click "Start"

If you like the results set the "Duration" back to zero and encode away!

This will reduce the video quality from DVD to SVCD quality but it reduced my 20 second clip from 15.2Megs to 5.7Megs.
It plays fine in DvPlayer and MPlayer.

If you don't like the resulting video quality try a higher video bitrate but of course the file size will be bigger.
DVD's are typically done with a bitrate of about 6000k to 8000k.

Hope this helps.

Thanks, and thanks for the new version of FFMpegGui! I'm having a little success now!

However, it seems that if I set the start off-set to anything other than 10, nothing gets encoded.

Still, my main goal is to encode my own DVDs. If I've created a DVD by just pressing record, it seems these DVDs can't be read by FFMpeg/Mencoder. However, if I've made a DVD by the recorder's direct dubbing feature (copying VHS->DVD), then it works (this is the actually a disc I've just tested now with FFMpeg and Mencoder).

BTW, your documentation refers to a couple of Quick Set-ups that don't seem to be included, such as Video Frames -> Jpegs.

Thanks, setting the stack worked! The line

now works!

I think there could be a lip-sync problem, though. I'll investigate.

Unfortunately, Mencoder can't seem to handle DVD that were created by my Panasonic DVD recorder.

DVDs, AVIs, and video work on the A1

Posted on: 2009/1/18 0:51 #287

Not too shy to talk

Hi,

I've been playing around with DVDs on my A1. There doesn't seem to be much talk about what I was trying to do, so I thought I might say a few words about my progress and perhaps anyone else can comment.

What I'm idealling trying to do it convert DVDs to AVIs, or "rip". However, my interest is backing up my own DVDs rather than copying commercial titles.

That being said, the only success I've had so far has been with a VOB from a commercial disc!

I started out with FFMpeg and FFMpeg GUI. I don't seem to be able to extract audio from VOBs; only by disabling audio can I extract a video stream.

I have been unable to extract video streams from DVDs recorded with my Panasonic DMR-ES35V recorder. Although DVPlayer can play them fine, FFMpeg reports them as being only a fraction of their true size (176x144 intead of 720x576) and cannot extract a video stream, it reports "no key frame" and "illegal MBA").

Using PeVOBill I was able to copy a VOB from a commercial disc to my HD, and then, with FFMpeg I was able to extract 19 minutes with no audio.

I then started playing around with mencoder. I now had the reverse problem, with Mencoder I can only extract audio. Any attempt to extract video results in a crash. I also cannot seem to extract audio as MP3 either, only AC3.

Anyway, I went back to the VOB ex-PeVOBill and was able to extract the AC3 audio, and then finally mux it together with the video extracted by FFMpeg. Finally, some success, I was able to copy 19 minutes of video and audio (albeit not exactly the material I wanted in the first place!). However, the resulting file is 660 MB, compared to the 1GB of the original VOB. After doing some reading on the handy links specified in the FFMpeg guide, I learned that I could crop the video to remove the overscan and reduce the filesize. This worked, but not by much- I now have a 550MB file. I could maybe also scale it, but so far I haven't tried that.

MP3 audio would also reduce filesize, but I can't seem to extract MP3 audio. Am I missing a library? I have the OS4 version of mpega.library in libs. Or are the versions of FFMpeg/Mencoder not compiled to use MP3?

I tried to replicate this on another disc, this time one of my own that FFMpeg is able to correctly identify the size of. However, when I try to extract a video stream, FFMpeg crashes.

That's where I'm up to so far. I guess I don't know too much about what I'm doing. There are some pages on the Net that are informative, but they're written for Linux users. For example,

mencoder dvd://2 -ovc lavc -lavcopts vcodec=mpeg4:vpass=1 -oac copy -o /dev/null
mencoder dvd://2 -ovc lavc -lavcopts vcodec=mpeg4:mbd=2:trell:vpass=2 \
-oac copy -o output.avi

dvd://2 seems to be the Linux DVD device. I substituted the path to the VOB and used NIL: for /dev/null, but the result was a crash.

It would be nice to hear from anyone else who has tried doing this sort of thing.

Re: YAM 2.5 PPC and mail tranfer from YAM 2.4

Posted on: 2009/1/17 23:59 #288

@MamePPCA1

When I switched to 2.5, I was able to copy all my folders across. However, I had 1 encrypted folder. When I tried to import that, only a fraction of my messages came through. Not sure what the problem was, I haven't got round to asking folks on the Yam list yet.

You don't have to import 1 mail at a time. Copy one of your old-format mail folders to Yam 2.5

Create a new folder and select "Existing directory". A file selector will pop-up, select the folder you just copied. The folder settings window will pop-up with all your existing settings for this folder (e.g., mailing list support, etc).

It will then prompt you with the filename of this first email, asking if you want to change it to the new format. Click on "All", and Yam 2.5 will import all the mail in that folder.

Looking through my folders now, most of them have all imported. Some have 3 or 4 still in the old format that haven't imported, and the encrypted folder has maybe half it can't read.

What are your Linux boot args? Maybe it would help to change "radeon" to "radeonfb".

Does it boot but it's text only, or does it not boot at all?

Sorry, I don't know what the Linux boot args are. I don't even know what Linux boot args are, or how to access them.

It boots to text, I see a DOS-like screen, and that's when I get the message that it can't initialise the display. Then it prompts for a login. I don't know what this login is (I bought the machine second hand), and it's not the same as the GUI login.

A1 + Radeon 9250 = No Linux

Posted on: 2009/1/4 8:30 #290

Not too shy to talk

Hi,

I'm not sure if this is the correct forum to bring this up, so apologies if it's OT.

Since upgrading my GFX card to a Radeon 9250 a couple of months back, I've lost the ability to boot in Linux. Whenever I do so, it says "can initialise X11" (or something).

Now I know nothing about Linux and was only just starting to play around with it. Can anyone tell me if there's an easy way to fix this? From my understanding it shouldn't've happened, the Raedon 9250 should be backwards compatible with the 7000.

Most of my drives (and the one the file was on) is 4.0's FFS. I also have a couple formatted with SFS. I also tried copying the file to ram and running it from there.

Hi,

I've had the error "Unable to open your tool [x]" pop up a couple of times on some software, specifically Stefan Rupprecht's SGarb, when I double click on the icon. Can someone tell me what's going wrong? I checked to make sure the file was a tool, not a project (a problem I recall from OS<=3).

Re: Looks like the sam is selling good?

@Antique

I'm a long-time A1200 user who was itching to buy a SAM. However, in July, I had the opportunity to buy a 2nd hand A1, and jumped for that instead.

Some of the reading I did suggested that people felt the A1 was better, except for the USB 2. Does anyone want to comment on that?

I'm currently having an extention put on my house so buying a 2nd computer (3rd if you still count the 1200 ;) ) is out of the question right now, but maybe if ACube still have units to sell next year I'd take a look.

I got DVPlayer to work with commercial DVDs. I found that I was using an older version of dvdvcd.plugin . Stephen, if you're reading this, it seem both files report the same version number, 51.2

I've also got PeeVOBill working as well, and have managed to copy at least 1 VOB from a commercial disc.

Still haven't sussed the problem I first encountered. Perhaps its caused by the default menu my Panasonic DVD recorder sticks onto mastered DVDs?

I obviously knew what I was doing way back when !!!

My problem is ... how do I access the Floppy drive ? I can't find an icon for it anywhere ... otherwise, should I uninstall MagicWB (how ?) or is there a better OS for a 1200 with a HD these days ? If so, is it free, can I download it from a PC & copy it ?!?

Any advice greatly appreciated ...

MagicWorkbench (MWB) isn't an Operating System, it's just a set of icons.

So far I'd only tried my own recorded disc. But now I've tried a couple of commercial discs and every one of them has failed. Whenever I tried and open them with e.g. DirOpus, they report read/write errors. DVPlayer/MPlayer lock up when I try and play either a file off the disc or the disc itself.

What is the file size of the VTS_01_1.VOB file. Is it smaller than the rest of your .VOB files? Is it the first or last VOB file in the order? What error does FFMpeg give you when you try to convert it. Something doesn't look right about this file since it doesn't report a Duration or bitrate. Can you play the file with MPlayer or DVPlayer?

The size of the file is 1073709056 bytes. There are two other VOBs on the disc of the same size, and a fourth of 1038516224 bytes. It's the first VOB.

FFMpeg doesn't actually give an error, it just produces a file that plays out as grey, with a picture size that seems to be that quoted in the info (176x144). Here's the output of a "Copy" operation as described above:

In that case, MEncoder (another video conversion utility) can be compiled to have support for DeCSS. I believe my mencoder compile for OS4 has this feature disabled, I might make a new version with DeCSS enabled if someone needs it.

That would be nice. In the meantime you can use PeeVOBill to copy a VOB file from a DVD then use ffmpegGUI on it.

I took a look at PeeVOBill but couldn't make much sense of it. The documentation is pretty slender, and I got the impression all it did was copy the VOB from DVD onto another source (which DOpus can do).
