Hi.
Would you tell me if NvBufferTransform function in the Tegra Multimedia API is asynchronous operation?
If so, how do I wait for the completion?
Thanks.

No,
It is synchronous API, when function finished.
Image data will be in destination buffer(fd).
Thank you!
Hi waynezhu.
If i do trnasform from yuv420 to ABGR32, NvBufferTransform() wil be faster than NvVideoConverter ? I have tested these two APIs and found no much difference. Any official description of these two APIs performance ?
Thansk.
Hi Jiamianshiye,
I think NvBufferTransform is faster, because NvVideoConverter has some additional thread synchronization workload.
Thanks

Out of curiosity, how is the Block → Pitch linear NV12 → YUV420 NvBufferTransform done that we see in the 00_video_decode example? CPU? GPU (CUDA)?
