FFmpeg resize and crop error

[z-machine95]

hello everyone,

I have problems encoding certain file with ffmpeg (libx265).

This is my command line:

"H:\Release\data\bin64\ffmpeg.exe" -hwaccel auto -y -i "H:\videotest\Transformers_test.mkv" -map 0:v:0 -vf scale=1024:545 -sws_flags lanczos -c:v libx265 -crf 20.0 -preset 5 -x265-params level=0:profile=undefined:pmode:no-pme:pme:no-high-tier:ref=3:bframes=4:open-gop:keyint=250:min-keyint=25:b-adapt=2:bframe-bias=0:rc-lookahead=20:no-scenecut:b-pyramid:me=hex:subme=2:merange=57:temporal-mvp:weightp:no-weightb:max-merge=2:no-weightb:no-rect:no-amp:vbv-bufsize=0:vbv-maxrate=0:vbv-init=0.9:no-strict-cbr:qcomp=0.6:qstep=4:aq-mode=1:aq-strength=1.0:cutree:no-early-skip:ctu=64:no-fast-cfb:ipratio=1.4:pbratio=1.3:cbqpoffs=0:crqpoffs=0:rd=3:psy-rd=0.3:psy-rdoq=1:b-intra:no-fast-intra:rdoq-level=1:no-tskip:no-tskip-fast:cu-lossless:tu-intra-depth=1:tu-inter-depth=1:strong-intra-smoothing:no-constrained-intra:nr-intra=0:nr-inter=0:qblur=0.5:cplxblur=20:signhide:sar=16 "H:\videotest\outpda1.mkv"

x265 return this error: "Picture height must be an integer or multiple of the specified chroma subsampling".

so I thought that declaring the Mod instead of the height could solve the problem:

"H:\Release\data\bin64\ffmpeg.exe" -hwaccel auto -y -i "H:\videotest\Transformers_test.mkv" -map 0:v:0 -vf scale=1024:2 -sws_flags lanczos -c:v libx265 -crf 20.0 -preset 5 -x265-params level=0:profile=undefined:pmode:no-pme:pme:no-high-tier:ref=3:bframes=4:open-gop:keyint=250:min-keyint=25:b-adapt=2:bframe-bias=0:rc-lookahead=20:no-scenecut:b-pyramid:me=hex:subme=2:merange=57:temporal-mvp:weightp:no-weightb:max-merge=2:no-weightb:no-rect:no-amp:vbv-bufsize=0:vbv-maxrate=0:vbv-init=0.9:no-strict-cbr:qcomp=0.6:qstep=4:aq-mode=1:aq-strength=1.0:cutree:no-early-skip:ctu=64:no-fast-cfb:ipratio=1.4:pbratio=1.3:cbqpoffs=0:crqpoffs=0:rd=3:psy-rd=0.3:psy-rdoq=1:b-intra:no-fast-intra:rdoq-level=1:no-tskip:no-tskip-fast:cu-lossless:tu-intra-depth=1:tu-inter-depth=1:strong-intra-smoothing:no-constrained-intra:nr-intra=0:nr-inter=0:qblur=0.5:cplxblur=20:signhide:sar=16 "H:\videotest\output3.mkv"

now x265 give another error: "Picture size must be at least one CTU".

but 1024x~545 is greater than 64^2 ...

There is a bad command or what?

Thanks to all!

EDIT:

another ffmpeg error I cannot solve.

I have same input and i have just trying to convert multiple audio track with multiple codec:

"H:\Release\data\bin64\ffmpeg.exe" -hwaccel auto -y -i "H:\videotest\Transformers_test.mkv" -map 0:v:0 -c:v libx265 -crf 20.0 -preset 0 -x265-params level=0:tune=fast-decode:profile=main:pmode:no-pme:pme:no-high-tier:ref=3:bframes=4:open-gop:keyint=250:min-keyint=25:b-adapt=2:bframe-bias=0:rc-lookahead=20:no-scenecut:b-pyramid:me=hex:subme=2:merange=57:temporal-mvp:weightp:no-weightb:max-merge=2:no-weightb:no-rect:no-amp:vbv-bufsize=0:vbv-maxrate=0:vbv-init=0.9:no-strict-cbr:qcomp=0.6:qstep=4:aq-mode=1:aq-strength=1.0:cutree:no-early-skip:ctu=64:no-fast-cfb:ipratio=1.4:pbratio=1.3:cbqpoffs=0:crqpoffs=0:rd=3:psy-rd=0.3:psy-rdoq=1:b-intra:no-fast-intra:rdoq-level=1:no-tskip:no-tskip-fast:cu-lossless:tu-intra-depth=1:tu-inter-depth=1:strong-intra-smoothing:no-constrained-intra:nr-intra=0:nr-inter=0:qblur=0.5:cplxblur=20:signhide:sar=16 -map 0:a:0 -c:a flac -compression_level 12 -lpc_type 3 -lpc_passes 2 -map 0:a:1 -c:a libvorbis -b:a 192k -map 0:a:2 -c:a libmp3lame -compression_level 0 -q:a 4 -map 0:a:3 -c:a ac3 -b:a 384k -map 0:s:0 -c:s copy -map 0:s:1 -c:s copy -map 0:s:2 -c:s copy -map 0:s:3 -c:s copy "H:\videotest\outputtest.mkv"

but the ouput is always with any combination of audio codec or encoding mode with all selected audio tracks converted with last declared configuration. For example in this case all 4 tracks are encoded as AC3 384 Kbps.


This is the report of the converted file:

again I really appreciate a solution. Thanks in advance.

You cannot use odd numbers as scaling target and 545 is odd - try 546 (preferrably divisable with 4 = 548). You should declare the scaler as -vf "scale=1024:546:flags=lanczos" instead of using -sws_flags switch.

P.S: Why would you scale to a size of 1024 x 2 pixels as you do in your second command line? Makes no sense..

first thing first thank you for the reply

1024:2 it's like says 1024x(auto adjust height to mod 2)... is it true? if it's not there is a way to declare mod adjustment?

and have you a fix for my second error about multiple video track conversions?

[TorBru]

"Mod" is short for modulus meaning it should be dividable with 2. You are using -c:a multiple times, only the last is used. You must declare a stream identifier for the codec (-c:a:0 -c:a:1 -c:a:2 and so on) in order to use different codecs. You must also declare stream id to quality and/or bit rate (-q:a:ID / -b:a:ID) if they should give the wanted result.

1024:2 means 1024x2 - modulo 2 is written as -2 so correct is 1024:-2
