vrecord only able to see one DV device - Ubuntu

[archisysio]

I'm running Ubuntu 22.04.4 LTS and would like to use vrecord to capture from multiple DV decks at the same time. However, the application only sees one DV device when I have multiple devices connected to the system.

I've tried different combinations of devices without any luck: HVR-1500As, DSR-1500As, and DSR-40s.

I currently have two HVR-1500As connected:

vrecord01@vrecord01:~$ grep . /sys/bus/firewire/devices/fw*/*_name /sys/bus/firewire/devices/fw0.0/model_name:DV-VCR /sys/bus/firewire/devices/fw0/model_name:HVR-1500 /sys/bus/firewire/devices/fw0/vendor_name:Sony /sys/bus/firewire/devices/fw1/model_name:Juju /sys/bus/firewire/devices/fw1/vendor_name:Linux Firewire /sys/bus/firewire/devices/fw2/model_name:Juju /sys/bus/firewire/devices/fw2/vendor_name:Linux Firewire /sys/bus/firewire/devices/fw3.0/model_name:DV-VCR /sys/bus/firewire/devices/fw3/model_name:HVR-1500 /sys/bus/firewire/devices/fw3/vendor_name:Sony

But dvrescue only sees one:

vrecord01@vrecord01:~$ dvrescue -list_devices 0x8004602012c0faf: Sony HVR-1500 [DV]

Version info:
vrecord01@vrecord01:~$ dvrescue --version DVRescue v.24.07 (MediaInfoLib v.24.06) by MIPoPS.

Is this possible? If so, please let me know if you need any additional info.

Hi @archisysio, thanks for reporting! Thanks for providing the output of dvrescue -list_devices, dvrescue indeed should be able to detect more than one device. Vrecord just parses the output of dvrescue -list_devices to create its list of inputs, so if that command is only detecting one deck then it looks like the issue is with dvrescue itself.

I'd suggest opening an issue with dvrescue and providing them the same outputs you've given here, and maybe they can get to the bottom of the issue. (Unfortunately, I can't test myself as I don't have enough inputs on my Linux machine to try multiple decks simultaneously).

Hi @privatezero, Thank you for your response and feedback.

I've opened ticket #935 with dvrescue.
