GStreamer nvh264enc:

Property Description
aq-strength Adaptive Quantization Strength when spatial-aq is enabled from 1 (low) to 15 (aggressive), (0 = autoselect)
aud Use AU (Access Unit) delimiter
b-adapt Enable adaptive B-frame insert when lookahead is enabled
bframes Number of B-frames between I and P
bitrate Bitrate in kbit/sec (0 = from NVENC preset)
const-quality Target Constant Quality level for VBR mode (0 = automatic)
cuda-device-id Get the GPU device to use for operations
gop-size Number of frames between intra frames (-1 = infinite)
i-adapt Enable adaptive I-frame insert when lookahead is enabled
max-bitrate Maximum Bitrate in kbit/sec (ignored for CBR mode)
min-force-key-unit-interval Minimum interval between force-keyunit requests in nanoseconds
name The name of the object
nonref-p Automatic insertion of non-reference P-frames
parent The parent of the object
preset Encoding Preset
qos Handle Quality-of-Service events from downstream
qp-const Constant quantizer (-1 = from NVENC preset)
qp-const-b Constant QP value for B frame, When >= 0, "qp-const-i" and "qp-const-p" should be also >= 0. Overwritten by "qp-const" (-1 = from NVENC preset)
qp-const-i Constant QP value for I frame, When >= 0, "qp-const-p" and "qp-const-b" should be also >= 0. Overwritten by "qp-const" (-1 = from NVENC preset)
qp-const-p Constant QP value for P frame, When >= 0, "qp-const-i" and "qp-const-b" should be also >= 0. Overwritten by "qp-const" (-1 = from NVENC preset)
qp-max Maximum quantizer (-1 = from NVENC preset)
qp-max-b Maximum QP value for B frame, When >= 0, "qp-max-i" and "qp-max-p" should be also >= 0. Overwritten by "qp-max" (-1 = from NVENC preset)
qp-max-i Maximum QP value for I frame, When >= 0, "qp-max-p" and "qp-max-b" should be also >= 0. Overwritten by "qp-max" (-1 = from NVENC preset)
qp-max-p Maximum QP value for P frame, When >= 0, "qp-max-i" and "qp-max-b" should be also >= 0. Overwritten by "qp-max" (-1 = from NVENC preset)
qp-min Minimum quantizer (-1 = from NVENC preset)
qp-min-b Minimum QP value for B frame, When >= 0, "qp-min-i" and "qp-min-p" should be also >= 0. Overwritten by "qp-min" (-1 = from NVENC preset)
qp-min-i Minimum QP value for I frame, When >= 0, "qp-min-p" and "qp-min-b" should be also >= 0. Overwritten by "qp-min" (-1 = from NVENC preset)
qp-min-p Minimum QP value for P frame, When >= 0, "qp-min-i" and "qp-min-b" should be also >= 0. Overwritten by "qp-min" (-1 = from NVENC preset)
rc-lookahead Number of frames for frame type lookahead
rc-mode Rate Control Mode
spatial-aq Spatial Adaptive Quantization
strict-gop Minimize GOP-to-GOP rate fluctuations
temporal-aq Temporal Adaptive Quantization
vbv-buffer-size VBV(HRD) Buffer Size in kbits (0 = NVENC default)
weighted-pred Weighted Prediction
zerolatency Zero latency operation (no reordering delay)
