Hi, I’m testing a new video card and wanted to try the sample transcodes so I threw together a system with CentOS 7.2 on it and I have a Tesla M4 video card on it.
I wanted to experiment with some basic encode/transcode.
I downloaded the Video_Codec_SDK and built the samples. And When trying the samples, I’m not getting any output. Am I running the command wrong? I didn’t see any error messages.
[root@localhost NvTranscoder]# ls -la HB_3840x2160.h264
-rwxr-xr-x. 1 root root 64967700 Sep 23 11:14 HB_3840x2160.h264
[root@localhost NvTranscoder]#
[root@localhost NvTranscoder]# ./NvTranscoder -i HB_3840x2160.h264 -o a.h264 -codec 1
[root@localhost NvTranscoder]#
[root@localhost NvTranscoder]# ls -la a.h264
-rw-r–r–. 1 root root 0 Sep 23 11:18 a.h264
[root@localhost NvTranscoder]#
Is it suppose to spit out any info or error messages?
Any help would be much appreciated.
