Hello All,
I have GTX 980 card. I downloaded nvenc sdk 5.0.1 and nvidia driver 346.35 driver. Both are installed successfully under Linux 64bit Ubuntu 14.04.

I can compile samples under nvenc SDK. NvTranscoder is working fine for transcoding from H264 to HEVC. However, NvEncoder using YUV 420p is not working correctly at all. I have a YUV 420p file 5.7Gbyte. I use below command:
./NvEncoder -i in.yuv -o out.ts -size 1920 1088 -codec 1 -preset hp -fps 25
However out.ts file size is huge like a few Gbytes and TS sync is broken.
Normally if I encode same YUV file to H264 it is 38 MByte (using ffmpeg + nvenc). If I transcode H264 file to HEVC using NvTranscoder it is 18 MByte. Both files working fine with DivX Player.
It looks there are problems with sample codes NvEncoder*. Any idea ?
Thanks,
