    v0.7.2 Stable

    builduser released this 2026-09-07 05:33:44 +02:00 | 11 commits to main since this release

    Fixes virtual camera devices not appearing in the interface at all, on a
    machine where they plainly existed as /dev/video10 and /dev/video11.

    What was wrong

    Enumeration walked /sys/devices/virtual/video4linux, which is a detail of how
    the kernel happens to arrange devices and is not present on every machine.
    Where that directory is absent the listing came back empty, and the interface
    reported no devices with nothing to suggest it had been looking in the wrong
    place.

    The nodes in /dev now decide what exists. What each one actually is still
    comes from asking its driver, which was already how loopbacks were told apart
    from real capture hardware.

    Two things made this harder to see than it should have been, and both are also
    fixed:

    • The device menu listed only devices it considered usable, so one that existed
      but could not be used looked identical to nothing existing. Every loopback
      device is now listed, with the reason when it cannot be used.
    • Enumeration opened each device for writing to test it, every couple of
      seconds. That is intrusive on a device whose advertised capabilities change
      depending on whether a writer holds it. Capabilities are now read with a
      non-blocking open, the way v4l2 tools probe, and whether a device can be
      claimed is decided when one is assigned.

    A new diagnostic

    ./streamsink -devices

    Lists every video node and what its driver says about it, with no filtering,
    then says which ones StreamSink is offering. For the case where the interface
    and /dev disagree.

    ./streamsink -check still exercises the whole path, ending with a test
    pattern written to a device and read back.
