<font

the first item,
Hama Video

promises: <br>
"Fluid video

thanks to a

Transform

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>
Just "-framerate 25
-video_size 1920x1080" before
-i as repeated in the code as
follows, where I tested to
encode to uncompressed v210

[video4linux2,v4l2 @
0x55944900e0c0] The driver
changed the time per frame
from 1/25 to 1/5<br>
<br>
I also read a related issue
and reply to this post at
Superuser, where 1920x1080 was
not supported on the webcam.<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
href="https://manpages.org/ffmpeg/1"
rel="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 -f
video4linux2 -input_format mjpeg -i
/dev/video0 out.mpeg</font><br>
</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
video input). </font></li>
<li><font face="monospace">input_format</font></li>
<li><font face="monospace"> Set the
preferred pixel format (for raw

allows one to select the input
format, when several are available.
</font></li>
</ul>
But what should be set as input_format in
this case?<br>

10 bpc (bits

component),
instead of the
tested 8 bpc
above, seems
to me would
have enlarged
the the
filesizes with
about 25%, or
to about 40

FFV1 lossless
compressed. </font></font></font><br>
<br>
Although the
FFV1
compression
results above
obviously used
yuv422p, 8bps
source SD and
FHD files as
input, it
seems for me
that the
encoding
speeds at 216
fps and 31 fps
for SD and FHD
respectively,
assumingly
should manage
realtime FFV1
encoding and
streaming of
PAL SD and HDV
at 25 fps as
well,
especially
with a faster
i7-6700 x 8
cpu. Comments
