v3.5+10 - defective image output (v3.0+1 is okay).

It is caused by
https://bitbucket.org/multicoreware/...2adf4ed7299d82 To go back to old behavior please add Code:
--no-early-skip --no-b-intra --limit-refs 3 |

I've yet to get --frame-dup to actually do anything, even with --dup-threshold at 20. And with source where there are lots of identical consecutive frames.
x265.exe --input SolLevante_SDRv2_1080p24_8bit.y4m --level-idc 4.0 --preset slower --tune animation --frame-dup --dup-threshold 20 --pools "-,+" --pass 1 --keyint 120 --bitrate 1000 --vbv-maxrate 12000 --vbv-bufsize 12000 --hrd --aud --colorprim bt709 --transfer bt709 --colormatrix bt709 -o SolLevante_SDR-1080p_1000_slower-dup20_p1.hevc --psnr --ssim --csv-log-level 1 --stats SolLevante_SDR-1080p_1000_slower-dup20.stats --csv SolLevante_SDR-1080p_1000_slower-dup20_p1.csv Every frame is at least 600 bytes. They're mostly Merge or Skip, but with very low percentages of Intra and Inter blocks of various sizes in the b-frames. Same in first and second passes. Anyone have any insights/suggestions? I'm trying a single-pass test. |

Yeah, it is frustrating. I'm still getting around 200 Kbps for what's a single B&W frame that's static for seconds. x265 without using --zones spends way too much on static title card and scrolling credits.
My guess is adaptive quantization isn't accounting for the benefit of SAO (ringing reduction) and tskip (efficient encoding of sharp edges) for discreet-tone content. The sequence is going down to QP 20 despite getting PSNR averaging >50. I'd think cutree would be providing more benefit as well. This kind of content looks pretty perfect at QP 40 with SAO and tskip. |

I'm using ffmpeg 4.4 and this command line:
ffmpeg.exe -i %1 -pix_fmt yuv420p -f yuv4mpegpipe -| x265.exe .... sometimes I get this and then it stops: av_interleaved_write_frame(): Broken pipe Error writing trailer of pipe:: Broken pipe How can this be solved? |

v3.5+10 - I get a refusal of encoding.
Code:
ffmpeg -i z:\space_6s.mkv -f yuv4mpegpipe - | x265 --y4m - --preset veryslow --hme --hme-search star,sea,full --bitrate 1000 z:\test.mkv Quote:

Also, can you use names instead of numbers for --hme-search? I would do it as "--hme-search 2,3,4" |

My new baby arrived today.
I look forward to take it for a spin with x265 (*_*) Intel Xeon Gold, 56c/112th with AVX-512 and this time is in a server room with freezing cold temperatures, so I dare AVX512 to make it hot! xD |

He doesn't like high resolution
Code:
ffmpeg -i z:\Park.mkv -f yuv4mpegpipe - | x265 --y4m - --preset veryslow --hme --hme-search star,sea,full --bitrate 1000 z:\test.mkv Quote:
Code:
ffmpeg -i z:\Park.mkv -vf scale="720:480" -f yuv4mpegpipe - | x265 --y4m - --preset veryslow --hme --hme-search star,sea,full --bitrate 1000 z:\test.mkv Quote:

ffmpeg.exe -i %1 -pix_fmt yuv420p -f yuv4mpegpipe - > test.y4m and then use test.y4m as an input file to a standalone x265.exe call to see what x265 does and debug that. |
