Third-party licenses

Application libraries

Linked into the app from npm. Versions are those in pimaso 1.0.3.

Native components

Shipped inside the modules above, each under its own licence.

Every component here is permissively licensed

Everything pimaso ships is under the MIT, Apache-2.0 or BSD-3-Clause licence. There is no copyleft component in the app, which is a deliberate constraint rather than a coincidence: pimaso’s own source is not published, and a component under a copyleft licence would either have to change that or be removed.

One was removed for exactly that reason. Until August 2026 a second playback backend built on libVLC shipped alongside the current one, as the fallback for cameras whose RTSP the default backend refuses. libVLC’s own core is permissive enough for this, but the prebuilt Android package used with it bundles further components under the GNU General Public License — so it was taken out. None of those components was doing anything for a viewer: they encode video and read DVDs, and this app only decodes a network stream.

It is a real loss, and worth stating rather than quietly dropping: a camera the app cannot play no longer has a second decoder to fall back to.

Modifications

One of the npm packages above is patched in this app, applied at build time rather than forked. react-native-video — it implements a texture-backed video surface that ships as an empty stub upstream, so a rotated camera can be drawn the right way up and a pinched tile stays inside its own bounds; and it forces RTP to be interleaved over the RTSP TCP connection instead of arriving on separate UDP ports, which is what makes cameras work on networks that drop the UDP.

The patch is MIT-licensed material under the same terms as the package it applies to, and is available on request from alefa-support@googlegroups.com.

Artwork

The app icon and in-app mark are imaso’s own artwork, used with the project’s identity. The interface icons are Material Symbols, Apache-2.0.
