Usage: /usr/bin/vpxdec filename Options: --help Show usage options and exit --codec= Codec to use --yv12 Output raw YV12 frames --i420 Output raw I420 frames --flipuv Flip the chroma planes in the output --rawvideo Output raw YUV frames --noblit Don't process the decoded frames --progress Show progress after each frame decodes --limit= Stop decoding after n frames --skip= Skip the first n input frames --postproc Postprocess decoded frames --summary Show timing summary -o , --output= Output file name pattern (see below) -t , --threads= Max threads to use --frame-parallel Frame parallel decode (ignored) -v, --verbose Show version string -S, --scale Scale output frames uniformly --frame-buffers= 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 --output-bit-depth= Output bit-depth for decoded frames --svc-decode-layer= Decode SVC stream up to given spatial layer --framestats= Output per-frame stats (.csv format) --row-mt= Enable multi-threading to run row-wise in VP9 --lpf-opt= Do loopfilter without waiting for all threads to sync. VP8 Postprocessing Options: --noise-level= Enable VP8 postproc add noise --deblock Enable VP8 deblocking --demacroblock-level= Enable VP8 demacroblocking, w/ level --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 % - Frame number, zero padded to 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. Included decoders: vp8 - WebM Project VP8 Decoder v1.17.0 vp9 - WebM Project VP9 Decoder v1.17.0
