According to the FAQ file in the videodev_2 branch, there are "early stepping" and "later stepping" versions of the 440BX. Just guessing, but maybe you have one of those early steppings? I can usually capture more than 20 minutes before I get the error. I assume you are using the original branch of the cvs driver. In case you've ever tried the zoran driver included in the kernel sources: did you have the same problem? Maybe you have never tried the version shipped with the (later 2.4) kernel? In that case, I would definitely recommend trying the videodev_2 branch. In my case, the kernel driver would give me an error syncing on a buffer, but I changed liblavrec.c from lavtools to exit cleanly when that occurs. I have written some python scripts to make capturing/encoding/ archiving easier, so in my recording script I just restart lavrec when it suddenly finishes and the total recording time hasn't been reached yet. So, in practice, I can capture almost reliably, but once in a while (quite often after more than your 20 minutes maximum, I have to add), I'm missing a few seconds because of the timer expired error. I can send you my scripts and explain where I've changed my liblavrec.c if it can help you. The normal cvs branch driver was worse, and I ended up with hanging lavrec processes. With the videodev_2 branch, I have the same results so far as with the kernel driver: occasional timer expired's, i.e. a workable but not perfect solution. > Oh yeah. I haven't found a known solution yet. If the videodev2 driver > turns out to do the trick for you, I'd be quite interested in knowing. I'd definitely give it a shot, if you have only tried the regular cvs or the old 8.0 release so far. Hope it helps.

[Mjpeg-users] jumping effect in encoded (svcd) videos...
Hi, I wanted to use mjpeg tool zu create svcds (with transcode). When playing those svcds on my dvd-player I notice every few seconds a small "jumping" in the sound. Then I watched the display of the player and saw that the time-display is also jumping at that moments, like this: 6..7..8..7..8..9..10..11..12..11..12..13.. when watching the same file with mplayer the display is jumping too, but I do not hear a disruption of the sound. The same happens when watching your demo-files from your web page (mpeg1-digital.mpg and pal-vid-svcd.mpg). Is this an error? What is this jumping effect when playing the videos? Or is it a fault of my dvd player (allthough the jumping can be seen in mplayer too) thanks for answering, regards, Michael Wohlwend --- This SF.NET email is sponsored by: SourceForge Enterprise Edition + IBM + LinuxWorld = Something 2 See! http://www.vasoftware.com ___ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users

Re: [Mjpeg-users] Command line tools to mix/overlay/join two lavrec-AVIs?
Hi, i just wrote two programs that do some conversion on LAV AVI streams. They are standalone programs that processes images in RGBA (red-green-blue-alpha) and writes the resulting images to an output stream. pngoverlay just overlays some PNG files over the input stream (nice for animated logos and some special FX). pngblend reads two LAV streams (left- and right part) of the same x- and y-dimensions and mixes them according to either a blend mask file or a rule (-l xleft -r xright, result is taken from either leftstream or rightstream or mixed). It also contains some code to read/write PNG files to/from RGBA data. In the bash script "qwe" some example calls are contained, please provide some input data in ../lav_examples. I hope somebody finds this useful.

The reason I asked is that the ATA controller (or the BIOS?) on my 440BX happily negotiates a nice, fast mode in the udma5 (IIRC) range with the disk, but anything above udma2 works like crap.

With the > built-in controller, that is. I've had this machine for quite a few years now, with no operational issues, apart from it running a bit hot. It's cool when idle, but gets pretty toasty when loaded. It's rock solid stable though, without a single unprovoked kernel panic, halt or reboot. I specifically went out and bought two new 40GB disks and the Promise controller when I put it back into use as a multimedia machine, and they've been operating without issue for about a year now. I had an attack of the stupids when I first built it years ago, and managed to short one of the fan pins. I caught that quickly when things started smelling like smoke. There's a teeny scortch mark on the board, and the CPU fans haven't worked since, but other than that it's been in 24/7 operation most of the time since without a single crash that wasn't due to fiddling with the kernel (2.4.19 USB routinely kills it, for example; 2.4.18 is fine). When I used it as a full-time mail/news/etc server I had an external fan blowing into it, which kept it nice and cool.

Although right now, I do notice something else re: file-flush=0. I have a FAT filesystem on the disk where I record, because I used to have a windows installation where I wanted to be able to access the recorded material. Now, I have the timer expired problem both when I record to an ext2 with some free space, or the usual FAT fs (without special --file-flush setting). But with --file-flush=0, recording to an ext2 fs seems to be stable (although I can't record more than a few minutes on this ext2 because of disk space right now, but so far it has worked every time). What I mean by "stable": It seems: when running lavrec interactively, all the fields in the bottom status line are continuously being updated; but everytime on a sync() (or with file-flush=0: when the disks writes a chunk of data), there is a short pause: the values (time, int, ...) stay the same, and after the data has been written, the "int" field is close to 0 for a short time (instead of a normal value of 39-40 which I approximately get in between these sync's). So, while writing to disk, no frames are being fetched from the video device, and after writing, all pending frames are quickly retrieved at once - must be that we have been in kernel mode for that while I guess? I just say this because I'm not sure whether that's what is supposed to happen or not. Now, when I run lavrec on the ext2 fs and with --file-flush=0, lavrec doesn't hang anymore on every write to disk (it still does hang for a while sometimes, but only once every 20 seconds or so). I'll free some more space, or I'll convert the FAT to ext2 one of these days, and report further. Thanks for the hint. Thanks to all you guys working on the driver and the other software!
