Fields

Name Description
AdvancedIntraCoding

Use advanced intra coding or MPEG-4 AC prediction.
AdvancedMotionVectors

Allow 4 motion vectors per macroblock / advanced prediction for H.263.
AllowSpeedupTricks

Allow non-spec compliant speedup tricks.
AllowUnalignedFrames

Allow decoders to produce frames with data planes that are not aligned to CPU requirements (e.g., due to cropping).
BitExactOperations

Use only bit-exact operations (except (I)DCT).
CalculatePSNR

Notify PSNR (Peak Signal-to-Noise Ratio) variables during encoding.
ClosedGOP

Use closed Group of Pictures (GOP).
DiscardCroppingInfo

Discard cropping information from the Sequence Parameter Notify (SPS).
ExportMotionVectors

Export motion vectors through frame side data.
ExportSkipInformation

Do not skip samples and export skip information as frame side data.
FixedQuantizationScale

Use fixed quantization scale.
ForceLowDelay

Force low latency encoding/decoding.
GlobalHeader

Place global headers in extradata instead of every keyframe.
GlobalHeadersAtKeyframes

Place global headers at every keyframe instead of in extradata.
GrayscaleOnly

Only decode or encode grayscale images.
HandleICCProfiles

Generate or parse ICC profiles on encode or decode, as appropriate.
InterlacedDCT

Use interlaced Discrete Cosine Transform (DCT).
InterlacedMotionEstimation

Use interlaced motion estimation.
KeepReadOrderOnFlush

Do not reset ASS ReadOrder field on flush for subtitle decoding.
None

No codec flags set.
OutputCorruptedFrames

Output even frames that might be corrupted.
OutputReconstructedFrames

Request the encoder to output reconstructed frames that would be produced by decoding the encoded bitstream.
PropagateOpaqueData

Propagate each packet's opaque data to its corresponding output frame or each frame's opaque data to its corresponding output packet.
QuarterPixelMotionCompensation

Use quarter-pixel motion compensation.
ShowAllFramesBeforeKeyframe

Show all frames before the first keyframe.
SkipBitstreamEncoding

Skip bitstream encoding.
TruncateAtPacketBoundaries

Allow input bitstream to be truncated at packet boundaries.
Use2PassRateControlFirstPass

Use internal 2-pass rate control in the first pass mode.
Use2PassRateControlSecondPass

Use internal 2-pass rate control in the second pass mode.
UseFrameDurations

Signal to the encoder that the values of frame durations are valid and should be used.
UseLoopFilter

Use loop filtering.
