There is some more from the VLC gui:
:v4l2-standard=PAL :input-slave=pulse://alsa_input.usb-Hauppauge_Hauppauge_Device_0014080666-01.stereo-fallback :live-caching=300
Using the pulse://<source name from paced list-sources|grep 'name:'> for the input slave worked finally.
To get the names of the device run:
pacmd list-sources | grep 'name:'

I am trying to get the Blackmagic Ultrastudio Express video capture card working with PAL over HDMI
I had it working with the desktop environment once but struggled ever since.

- Extensive list of details on diplsay and the pi: https://www.improwis.com/projects/hw_RaspberryPiSPIdisplays/
Ultrastudio Express' EDID is: device_name=HXA-BMD_HDMI
# Get the edid info:
tvservice -d /tmp/edid
# Read the edid info:
edidparser /tmp/edid
# preferred resolution
edidparser /tmp/edid | grep preferred
# supposedly this refreshes the screen buffer
fbset -depth 8 && fbset -depth 16
# maybe to 8 bit for PAL
fbset -depth 16 && fbset -depth 8
Did not resolve the BMD card to recognise 576i or p over HDMI
For composite there is no matching cable,
Using 720p and stretch window then anamorphic conversion of the BMD UltraStudio Express to convert it back to PAL 4:3. Basically 720p down to SD; then use PAL 625i50 preset while capturing.
