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 .av1b
files, with obu_size set) and OBU sequences (.obu
files, 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
