Bug ID: 2307697
Summary: Review Request: libklvanc - VANC Processing Framework
Product: Fedora
Version: rawhide
Hardware: All
OS: Linux
Status: NEW
Component: Package Review
Severity: medium
Priority: medium

Target Milestone: ---
Classification: Fedora
Spec URL: https://slaanesh.fedorapeople.org/libklvanc.spec
SRPM URL: https://slaanesh.fedorapeople.org/libklvanc-1.6.0-1.fc40.src.rpm
Description:
Libklvanc is a library which can be used for parsing/generation of Vertical
Ancillary Data (VANC) commonly found in the Serial Digital Interface (SDI) wire
protocol.
The library includes a general parser/decoder and an encoder for VANC lines, as
well as the ability to both decode and generate protocols commonly found in
SDI,
including:
- SMPTE ST 334 - CEA-708 closed captions in VANC
- SMPTE ST 2016 Active Format Descriptor (AFD) and Bar Data
- SCTE-104 Ad triggers
- SMPTE ST 2038 arbitrary VANC encapsulation
- SMPTE ST 12-2 Timecodes
- SMPTE RDD 8 Subtitle Distribution packets
- SMPTE ST 2108-1 HDR/WCG Metadata Packing and Signaling
By providing both encoders and decoders, the library can be used for common use
cases involving both capture of SDI (and subsequent decoding) as well as
generation of VANC for inclusion in an SDI output interface. This includes
computing/validating checksums at various levels and dealing with subtle edge
cases related to VANC line formatting such as ensuring packets are contiguous.
The library also provides utility functions for various colorspaces VANC may be
represented in, including the V210 format typically used by BlackMagic Decklink
SDI cards.
