I have never been able to record more than 20 minutes with my DC10plus
and 440BX motherboard (ASUS P2B-D).  I've tried it with both a 36057 and
a 36067 based board.  Trying the newer videodev2 driver is still on my
todo list.

This is what I almost always get, at right around twenty minutes.  It
doesn't matter what I've got --file-flush, -U, -a, or -q set to, or what
the video source is.

> Is this a known problem?

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.

Brian.

You are right! That solved the problem and
mpeg2dec -s -o YUVh sample.mpg | yuvplay
now plays well.

_Thank you_ very much for your help and patience!

Re: [Mjpeg-users] stability issues with 440BX and DC10plus?

Hello,

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

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.
Kind regards,
Jonas

[Mjpeg-users] jumping effect in encoded (svcd) videos...

2003-01-12 Thread Michael
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

Here's a patch which uses __func__ along with %s in the printk's. The debug 
output in vpx3220.c should probably be rewritten, but as I'm not sure yet 
which of vpx3220.c and vpx32xx.c will be kept, I won't do it for now :-)

The patch compiles fine with gcc-2.95, someone should test it with gcc-3.

Re: [Mjpeg-users] Command line tools to mix/overlay/join two lavrec-AVIs?

2003-01-12 Thread Torsten Mohr
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.


Best regards,
Torsten.

Urm...? On a 440BX mainboard?!?

/me gets confused

Last resort solution: --file-flush=0. ;-). If it doesn't help, even if
the card has its own IRQ, please report it again and I'll have a closer
look. Even first-time records should work (doh!).

With an ATA-100 controller, udma5 should be ok, I guess. 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.

Tried this before without success. 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!

Kind regards,
Jonas

In my kernel, I enable UDMA by default.

/dev/hdc:

 Model=ST330630A, FwRev=3.21, SerialNo=3CK0DYN4
 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
 RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0
 BuffType=unknown, BuffSize=2048kB, MaxMultSect=16, MultSect=16
 CurCHS=17475/15/63, CurSects=16513875, LBA=yes, LBAsects=59777640
 IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
 PIO modes: pio0 pio1 pio2 pio3 pio4 
 DMA modes: mdma0 mdma1 mdma2 udma0 udma1 *udma2 udma3 udma4 
 AdvancedPM=no WriteCache=enabled
 Drive Supports : Reserved : ATA-1 ATA-2 ATA-3 ATA-4 

Looks ok. Explicitly doing hdparm -X66 /dev/hdc does't solve the problem
either.

Thanks for your reply.
Kind regards,
Jonas
