Prevent libavformat (FFmpeg) from adding "ENCODER" tag to output / help stripping the tags
2 mars 2014, par Wyatt8740I made a bash script that transfers audio or video metadata from one file to another, regardless of media container format, via FFMpeg. My problem is that FFMpeg consistently adds a 'ENCODER' tag.
Example :
Before running through FFMpeg :
File : track01.cdda.flac
Metadata:
ALBUM : Wish You Were Here
ARTIST : Pink Floyd
COPYRIGHT : 1975 Harvest Records
DATE : 1975
GENRE : Experimental Rock
TITLE : Shine On You Crazy Diamond
track : 1After running through FFMpeg :
File : track01-iphone-alac.m4a
Metadata:
ALBUM=Wish You Were Here
ARTIST=Pink Floyd
COPYRIGHT=1975 Harvest Records
DATE=1975
GENRE=Experimental Rock
TITLE=Shine On You Crazy Diamond
track=1
ENCODER=Lavf55.12.100So really, I want to either force FFMpeg to not add the 'ENCODER' tag, or I want to strip that tag off afterwards. Is there a way to do this ? I really don't want to spend hours trying to compile FFMpeg again on my Pentium 4 HT - the only working computer I have at the moment. I'd prefer not to have to use another program unless it's related enough to FFMpeg or MPlayer/Mencoder that I won't have to install anything new if I have those installed.

Encode HEVC/H.265/HDR Video for YouTube from 10bit Pro-Res using FFmpeg
30 janvier 2018, par Rodrigo PoloI want to have an HDR YouTube video published, my source file is either an Apple ProRes or DNxHR using a chroma subsamplig 4:4:4 or full RGB, both 10bit, so the original source file has all what is needed in order to be encoded into a 10bit 4:2:0 H.265/HEVC (HDR).
I have followed some answers listed here, reviewed lots of different approaches, tried out many different commands without success, colors aren’t right when using only FFmpeg, to much red, when using only Adobe to encode into H.264 with the recommended settings on their support page, the results is darker, here are the commands I’ve using :
I have tried this :
ffmpeg \
-i input.mov \
-c:v libx265 \
-tag:v hvc1 \
-crf 21 \
-preset fast \
-pix_fmt yuv420p10le \
-x265-params "colorprim=bt2020:transfer=smpte2084:colormatrix=bt2020nc:master-display=G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,10):max-cll=1000,400" \
-c:a libfdk_aac \
-b:a 128k \
-ac 2 \
-ar 44100 \
-movflags +faststart \
output.mp4And this :
ffmpeg \
-y \
-hide_banner \
-i input.mov \
-pix_fmt yuv420p10le \
-vf "scale=out_color_matrix=bt2020:out_h_chr_pos=0:out_v_chr_pos=0,format=yuv420p10" \
-c:v libx265 \
-tag:v hvc1 \
-crf 21 \
-preset fast \
-x265-params 'crf=12:colorprim=bt2020:transfer=smpte-st-2084:colormatrix=bt2020nc:master-display="G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)":max-cll="1000,400"' \
-c:a libfdk_aac \
-b:a 128k \
-ac 2 \
-ar 44100 \
-movflags +faststart \
output.mp4I have also tried using MKVToolNix in order to insert the metadata into the encoded HEVC/H.265 file with the following command :
/Applications/MKVToolNix-9.7.1.app/Contents/MacOS/mkvmerge \
-o output.mkv \
--colour-matrix 0:9 \
--colour-range 0:1 \
--colour-transfer-characteristics 0:16 \
--colour-primaries 0:9 \
--max-content-light 0:1000 \
--max-frame-light 0:300 \
--max-luminance 0:1000 \
--min-luminance 0:0.01 \
--chromaticity-coordinates 0:0.68,0.32,0.265,0.690,0.15,0.06 \
--white-colour-coordinates 0:0.3127,0.3290 \
input.mp4But the result is the same and YouTube don’t recognize the file as an HDR file, it does only with the first FFmpeg command and with the file encoded with Adobe Premiere, but the colors don’t look well, so, maybe I’m getting some concept wrong, thanks for your help.
