ffmpeg x265 pipe no audio
I am using a static version of ffmpeg and x265 to encode an 8 bit .mp4 to 10 bit.
Everything goes great but there is no sound! I've looked everywhere for an answer. Can anyone help me? Code:
ffmpeg.exe -hwaccel auto -ss 00:26:45 -y -t 10 -i "vid.mp4" -c:a libfaac -ar 48k -b:a 210k -map 0:0 -an -sn -vsync 0 -strict -1 -pix_fmt yuv444p10le -f yuv4mpegpipe - | x265 --preset medium --input - --output-depth 10 --y4m --crf 18.00 "vid(10bit).mp4" |

Your ffmpeg output is just video to pipe. You have to process audio separately, I don't see a reason though why you use x265.exe, you might as well use ffmpeg for x265 encoding.

I have tried everything to get ffmpeg to output a 10 bit video but it wont.
Here is my code for that attempt. Always comes out 8 bit. Code:
ffmpeg.exe -hwaccel auto -y -i "vid (8bit).mp4" -preset medium -crf 18 -c:a aac -b:a 192k -c:v libx265 -x265-params -format yuv420p10le "Vid (10bit).mp4" And here is the result. Code:

I cant get ffmpeg to output 10 bit.
Here is my code Code:
ffmpeg.exe -hwaccel auto -y -i "vid (8bit).mp4" -preset medium -crf 18 -c:a aac -b:a 192k -c:v libx265 -x265-params -format yuv420p10le "Vid(10bit).mp4" Code:
ffmpeg.exe -hwaccel auto -y -i "vid (8bit).mp4" -preset medium -crf 18 -c:a aac -b:a 192k -c:v libx265 -x265-params -pix_fmt yuv444p10le "Vid(10bit).mp4" I get the error at the very bottom Code:
[NULL @ 0000000003011520] Unable to find a suitable output format for 'yuv420p10le' yuv420p10le: Invalid argument I don't know how to output the audio separately. Can you recommend some instructions or examples? Thanks for helping. This has driven me crazy. |

I'm a GUI user, wait a few hours for a CLI user to help you, sorry.

Either get/build ffmpeg binary with 10 bit x265 support or do a 3 step process:
Code:
ffmpeg.exe -y -hwaccel auto -ss 00:26:45 -t 10 -i "vid.mp4" -map 0:v:0 -pix_fmt yuv420p10le -f yuv4mpegpipe - | x265 --preset medium --input - --output-depth 10 --y4m --crf 18.00 "vid(10bit).265" ffmpeg.exe -y -ss 00:26:45 -t 10 -i "vid.mp4" -map 0:a:0 -c:a aac -ar 48k -b:a 210k audio.m4a mp4box -add "vid(10bit).265" -add "audio.m4a" -new "output.mp4" |

Thank you so much. I ended up compiling my own library using only a 10 bit version of x265.
When I get home I'm going to also test your command line. Thanks again to everyone who tried to help me out. Last edited by dooley2009; 18th June 2017 at 22:19. |
