writegen

Stream to file

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

Generic single stream to file converter, used when extracting/converting PIDs.
The writegen filter should usually not be explicitly loaded without a source ID specified, since the filter would likely match any PID connection.

Options

exporter (bool, default: false): compatibility with old exporter, displays export results
pfmt (pfmt, default: none, minmax: none,yuv420,yvu420,yuv420_10,yuv422,yuv422_10,yuv444,yuv444_10,uyvy,vyuy,yuyv,yvyu,uyvl,vyul,yuyl,yvyl,nv12,nv21,nv1l,nv2l,yuva,yuvd,yuv444a,yuv444p,v308,yuv444ap,v408,v410,v210,grey,algr,gral,rgb4,rgb5,rgb6,rgba,argb,bgra,abgr,rgb,bgr,xrgb,rgbx,xbgr,bgrx,rgbd,rgbds,uncv): pixel format for raw extract. If not set, derived from extension

auto: selects between no and first based on media type

split (bool, default: false): force one file per decoded frame

sstart (uint, default: 0): start number of frame to forward. If 0, all samples are forwarded
send (uint, default: 0): end number of frame to forward. If less than start frame, all samples after start are forwarded
dur (frac, default: 0): duration of media to forward after first sample. If 0, all samples are forwarded
merge_region (bool, default: false): merge TTML regions with same ID while reassembling TTML doc
vtth (enum, default: seg): vtt header injection mode
single: inject only at first frame of the stream
seg: inject at each non-empty segment
