I noticed "must be DV", but was not sure how literal
"DV" was meant(?)<br>
<br>
According to the ffmpeg man page for iec61883:<br>
<i>The iec61883 capture device supports capturing
from a video device connected via IEEE1394
(FireWire), using <b>libiec61883 </b>and the new
Linux FireWire stack (juju). This is the <b>default
DV/HDV input method</b> in Linux Kernel 2.6.37
and later, since the old FireWire stack was
removed.<br>
Specify the FireWire port to be used as input
file, or "auto" to choose the first port
connected.<br>

<br>
Yeah, I understand that will be difficult. <br>
My legacy SuperMicro workstation had a Firewire port
on its front panel, which now is working with a <br>
Texas Instruments XIO2200A IEEE-1394a-2000
Controller (pci) mounted on the MSI mobo.<br>
<br>
libIEC 61883 has not been enabled on my system
ffmpeg-7, but recently I got this bug accepted by
OBS, and iec61883 is just enabled in Factory.<br>
So when it is available for Slowroll, I will try
recording with ffmpeg.<br>

According to the manual:<br>
<small>The file format must be Quicktime for

So I tried first <br>
Shift-P<br>
FFMPEG and qt, mp4 audio and dv_pal.qt video<br>
<br>
I also tried <br>
FFMPEG mpeg, Audio mpeg_mp2, Video mpeg and
mpeg_hdv<br>
<br>
But got these error messages in both cases
using default port 0 or alternative port 1<br>
<br>

Add here that dvgrab 3.5 was released 07.09.2009<br>
This version automatically detects when your device is
DV or HDV so you do not have to remember to supply "-f
hdv." <br>
<a

* Automatically detect DV vs. HDV when not using
-noavc, -input, or -stdin.<br>
* Now waits indefinitely for DV or HDV instead of
giving up after 10 seconds.<br>
* Bugfixes<br>
<br>
<br>
Repeat here my short dvgrab test on Leap 15.6, which
also has a possible related "libiec61883 error: Failed
to get channels available."<br>
Yet, robust and worked as follows:<br>
<br>
dvgrab -size 0 -autosplit<br>

I found a tip regarding the libiec61883 error back on an old
linux1394-user list:<br>

<br>
</font>and then the iec error disappeared using dvgrab.<br>
<br>
This didn't solve Cingg's record issue using iec61883, but seemingly
reduced the error output to:<br>
<br>
<font face="Courier New, Courier, monospace">int

<br>

<br>
"test-mpeg2" was initially used and is still packaged, but seemingly
doesn't work for me (not really important): <br>
