I’m trying to run AppTrans app from Video_Codec_SDK_9.1.23/Samples/AppTranscode on Ubuntu machine with GeForce RTX 2070 gpu.
I’m trying to transcode the input file to two hevc files with different bitrates. On output I do have two files, they both are playable, but has exactly the same size and diff returns nothing, it’s just the same file.
At the beginning of the run the encoder parameters are dumped out, and I do see the assigned bitrate.
mediainfo returns no bitrate info(but, for example, correct fps), and ffprobe gives N/A for bitrate.
Please advice. Thanks in advance. Here is my console output:
