Does Video Encoders support B frame for H.265 on Tx1?
as NVIDIA Tegra Linux Driver Package Development Guide 28.2 Release shows:
H.265
I420, NVMM:I420, NVMM:NV12
3840 x 2160 at
30 fps
Up to 100 Mbps
Supported features include:
• control-rate
• Bitrate
• Peak-bitrate
• Iframeinterval
• SliceIntrarefreshEnable
• Sliceintrarefreshinterval
• Bit-Packetization
• VBV-Size
• Temporal-tradeoff
• EnableMVBufferMeta
• qp-range
• MeasureEncoderLatency
• EnableTwopassCBR
• Preset-level
• EnableStrimgentBitrate
• Insert-SPS-PPS
• Num-B-Frames
• Slice-Header-Spacing
• Profile
• insert-aud
• insert-vui
• Force-IDR
but, how could I test it?

as I run the MMAPI samples failed
Encoding B frames is not supported in H265 HW encoder.
OK！thank you!
what about TX2?
Neither on TX1 nor on TX2. It is h264 only.
