- --limit=<arg>
- Stop decoding after n frames
- --skip=<arg>
- Skip the first n input frames
- --postproc
- Postprocess decoded frames
- --summary
- Show timing summary
- -o <arg>, --output=<arg>
- Output file name pattern (see below)
- -t <arg>, --threads=<arg>
- Max threads to use
- --frame-parallel
- Frame parallel decode
- -v, --verbose
- Show version string
- -S, --scale
- Scale output frames uniformly
- --frame-buffers=<arg>
- Number of frame buffers to use
- --md5
- Compute the MD5 sum of the decoded frame
- --error-concealment
- Enable decoder error-concealment
- -k, --keep-going
- (debug) Continue decoding after error
VP8 Postprocessing Options:¶
- --noise-level=<arg>
- Enable VP8 postproc add noise
- --deblock
- Enable VP8 deblocking
- --demacroblock-level=<arg>
- Enable VP8 demacroblocking, w/ level
- --pp-debug-info=<arg>
- Enable VP8 visible debug info
- --pp-dbg-ref-frame=<arg>
- Display only selected reference frame per macro block
- --pp-dbg-mb-modes=<arg>
- Display only selected macro block modes
- --pp-dbg-b-modes=<arg>
- Display only selected block modes
- --pp-dbg-mvs=<arg>
- Draw only selected motion vectors
- --mfqe
- Enable multiframe quality enhancement
Output File Patterns:¶
- The -o argument specifies the name of the file(s) to write to. If the argument does not include any escape characters, the output will be written to a single file. Otherwise, the filename will be calculated by expanding the following escape characters:
- %w
- - Frame width
- %h
- - Frame height
- %<n> - Frame number, zero padded to <n> places (1..9)
- Pattern arguments are only supported in conjunction with the --yv12 and --i420 options. If the -o option is not specified, the output will be directed to stdout.
