ufobu

IVF/OBU/annexB writer

Register name used to load filter: ufobu
This filter may be automatically loaded during graph resolution.

This filter rewrites VPx or AV1 bitstreams into a IVF, annexB or OBU sequence.
The temporal delimiter OBU is re-inserted in annexB (.av1 and .av1bfiles, with obu_size set) and OBU sequences (.obufiles, without obu_size)
Note: VP8/9 codecs will only use IVF output (equivalent to file extension .ivf or :ext=ivf set on output).

Options

rcfg (bool, default: true): force repeating decoder config at each I-frame
