<br>
<font

the first
item, Hama

received. It
promises: <br>
"Fluid video

thanks to a
picture
frequency of
60 Hz and
1080p with
Full HD.
Transform

video cameras
into a
high-resolution
USB web
camera".<br>
<br>
I have done a
quick, first
test using my
Sony HDR-FX7E
camera. This
is a HDV 1080i
camcorder with
MPEG-2 video
compression at
25 mbps on
tape
1440x1080,
50i25fps,
4:2:0 and MP2
stereo audio.
Currently it's
cassette deck
is broken and
needs repair
service. <br>
<br>
But according
to Steve
Mullen's V1
and FX7
handbook (not
mentioned in
the manual):<br>
</font>
<blockquote><font
face="monospace">1. When the camera is operating, the EIP (Enhanced
Image
Processor)
generates
uncompressed
1440x1080i
with a 4:2:2
color space. </font><font
face="monospace">Digital 4:2:2 data are output via the HDMI port while
4:2:2 analog
is output via
component-out.
Therefore, you
can record
4:2:2 live HD
video from the
camera without
MPEG-2
compression.
V1 and FX7
provide an
HDMI output
port that
carries
uncompressed
4:2:2, 8-bit,
digital video
plus
dual-channel,
PCM, 16-bit,
48kHz audio
When the
camera is
running. </font><br>
<br>
<font
face="monospace">2.
If you are
playing a
1080i50 or
1080i60 HDV
tape. The
4:2:0 MPEG-2
is decoded and
chroma
up-scaled to a
4:2:2. The
HDMI</font><br>
<font
face="monospace">chip
downscales
1440 to 1280
while it
up-scales 540
to 720. The
result is
720p50 or
720p60, which
is output via
HDMI.<br>
</font></blockquote>
<font
face="monospace">That
is, I have
tested section
1 now, but see
now that I
didn't test
1440x1080
resolution.
The only
resolution I
got to work at
25 fps was
720x576 (SD),
while HD
1280x720 and
FHD 1920x1080
were set down
to 10 fps and
5 fps
respectively
by the driver
and caused
jumpy
playback.<br>

<br>
This may well work
better. I have to
admit that I have
never studied the
difference between
shared usb buses.
My thought was to
try to change the
connected usb
devices, but
tested first the
only free usb3
port (blue) on the
add-on frontpanel
of the
workstation. The
other two usb3
ports are on the
backpanel and are
used for the Asus
blu-ray burner and
8TB Seagate
expansion video
disc. <br>
<br>
The other usb
ports on both
panels are usb2
ports, whereof two
for the wireless
keyboard and mouse
on the fronpanel.
What I possibly
already have
mentioned before,
is that sometimes
if I connect a
usb(2) device or
memory to the usb3
port on the
frontpanel, this
cause hang on the
keyboard or mouse.
But this didn't
happend this time
with the USB3
capture stick.<br>

I also tried that link's
suggested syntax<br>
<pre><code>ffmpeg -y -t 15 -f video4linux2 -video_size 1920x1080 -input_format nv12 -timestamps abs -use_libv4l2 1 -i /dev/video0 out.mov</code>
</pre>
but it didn't work for me,
just quitted ffmpeg with<br>
<blockquote><font
face="monospace">Unrecognized
option 'timestamps'.</font><br>
<font face="monospace">Error
splitting the argument
list: Option not found</font><br>
</blockquote>
Looking at ffmpeg man pages at
<a

rel="noreferrer noreferrer
noreferrer noreferrer
noreferrer noreferrer"
target="_blank"
moz-do-not-send="true"
class="moz-txt-link-freetext">https://manpages.org/ffmpeg/1</a>
there also is a similar
video4linux2 syntax example<br>
<blockquote><font
face="monospace">Grab and
record the input of a
video4linux2 device, leave
the frame rate and size as
previously set:</font><br>
<font face="monospace">ffmpeg

</blockquote>
<ul>
<li><font face="monospace">video_size</font></li>
<li><font face="monospace">
Set the video frame
size. The argument must
be a string in the form
WIDTHxHEIGHT or a valid
size abbreviation. </font></li>
<li><font face="monospace">pixel_format</font></li>
<li><font face="monospace">
Select the pixel format
(only valid for raw

<li><font face="monospace">input_format</font></li>
<li><font face="monospace">
Set the preferred pixel
format (for raw video)

select the input format,

</ul>
But what should be set as
input_format in this case?<br>

What I feel unused to is the need to set ffmpeg code both Audio and
Video input format and input device respectively.<br>
A couple of syntax examples for audio found:<br>
