x265 and frame-threads?

[TheCompWiz]

I've rebuilt VLC from source about 15-times (as well as all the bits relating to ffmpeg... and a bunch of other dependencies) and keep running into this one error when trying to transcode to x265 from a decklink card.

Using the following syntax:

Code: Select all

cvlc decklink:// --sout "#transcode{vcodec=x265,frameNumThreads=4,vb=5568,fps=25,scale=Auto,acodec=mp3,ab=192,channels=2,samplerate=44100}:http{dst=:8081/file.avi}"

I get the following results:

Code: Select all

x265 [info]: HEVC encoder version 1.9 x265 [info]: build info [Linux][GCC 5.3.1][64 bit] 8bit+10bit+12bit x265 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX AVX2 FMA3 LZCNT BMI2 x265 [error]: frameNumThreads (--frame-threads) must be [0 .. X265_MAX_FRAME_THREADS) [00007f1ca00015a8] x265 encoder error: cannot open x265 encoder [00007f1cac4f2118] stream_out_transcode stream out error: cannot find video encoder (module:any fourcc:hevc). Take a look few lines earlier to see possible reason.

I've tried repeatedly adding the "--frame-threads" parameter but always end up with this:

Code: Select all

vlc: unknown option or missing mandatory argument `--frame-threads'

Can someone tell me what I'm doing wrong here?

I know that this server has 24-logical cores (yes... really .. 24.) I don't know if that might be beyond X265_MAX_FRAME_THREADS... and that might be causing some sort of issue...
