PySpiral
PySpiral is the legacy SpiralDB Python API. It remains available as
pip install pyspiral with import spiral, and continues to target the old
table format.
The new engine SDK is published separately as spiraldb and uses
import spiraldb.
Optional H.264 Encoder
pyspiral keeps the GPL spiral-h264 encoder out of the default install. To use
the production H.264 encode bridge, install the external encoder package:
pip install 'pyspiral[h264]'
This installs the spiral-h264 console command from PyPI. PySpiral still invokes
it as an external process; source decode/filtering remains a system ffmpeg
dependency. You can override the encoder executable with --encoder, the
encoder= Python argument, SPIRAL_H264, or SPIRAL_H264_BIN.
Third-Party Notices
PySpiral packages include spiral/THIRD_PARTY_NOTICES.md. That notice documents
the FFmpeg dynamic-linking boundary, the LGPL-only release requirement for
FFmpeg-based builds, and the external GPL spiral-h264 encoder boundary.
