• How to completely hide the timestamp from recording/image from FFMPEG ? [migrated]

  3 septembre 2021, par Lakshay

  I tried multiple commands from similar questions, but none is working for me.

  


  -timecode 00:00:00:00 gives error "timestamp is out of range for mov/mp4 format"

  


  -vf or datetext doesn't work !

  


  Full command : ffmpeg -i "rtsp://192.168.0.100:554/user=admin&password=&channel=3&stream=0.sdp?real_stream--rtp-caching=100" -vcodec copy -r 60 -t 3540 -timecode 00:00:00:00 -y 3.mp4

  


  Output log :

• FFMPEG encoding 16bit video data results in 10bit

  12 mars 2023, par Jl arto

  I want to compress a depth map that has 16 bits of information per pixel. In general, such depth maps can be stored in different ways, e.g. p016le, gray16le, yuv420p16le, yuv444p16le, ... but for simplicity, let's assume the depth map is a yuv420p16le (where the y-channel contains the depth).

  


  For some reason when encoding with hevc_nvenc (I use an NVIDIA GTX 1660 Ti GPU), ffmpeg (the command line tool) changes the pixel format to a 10 or 12 bit variant (p010le, gray12le, yuv420p10le, yuv444p12le, ...), but I would like to keep the full 16 bits, since this affects the quality of the depth stored.

  


  For example :

  


  ffmpeg.exe -s:v 1920x1080 -r 30 -pix_fmt yuv420p16le -i depth_yuv420p16le.yuv -c:v hevc_nvenc -pix_fmt yuv444p16le output.mp4


  


  If I use ffprobe on the output.mp4, it tells me that the underlying pixel format is actually yuv444p10le. (Decoding and looking at the raw pixel data, I can confirm that the precision has decreased from 16 bits to 10 bits).

  


  I hope 16 bit compression is possible, since according to

  


  ffmpeg -h encoder=hevc_nvenc


  


  the supported pixel formats are :

  


  hevc_nvenc: yuv420p nv12 p010le yuv444p p016le yuv444p16le bgr0 rgb0 cuda d3d11


  


  But p016le results in a p010le output, and yuv444p16le in yuv444p10le.

  


  Does anyone know where the problem could lie ? Should I re-install ffmpeg (version 4.3.2-2021-02-27-essentials_build-www.gyan.dev) ? Is it because of Windows 10 having limited encoding/decoding capabilities ? Will buying the HEVC Video Extensions help solve this problem ?

  


  Additional info : using libx256 does not look like it will work for this purpose, since the supported pixel formats are :

  


  libx256 : yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p gbrp yuv420p10le yuv422p10le yuv444p10le gbrp10le yuv420p12le yuv422p12le yuv444p12le gbrp12le gray gray10le gray12le


  


  Any help would be greatly appreciated.

  


• FFMPEG is throwing Not enough memory resources on Azure VM [closed]

  20 août 2021, par Gaurav

  I have 500 MB video file which I am converting to MP4 format.

  


  My laptop is i7 and 16 GB Memory and ffmpeg is able to convert the file.
Command used is as follows :

  


  ffmpeg.exe -i  "a.mp4" -c:v  libx264  -crf  35  -preset  ultrafast  "b.mp4"


  


  On Azure , I have D series machine with 8 core and 32 GB. Memory used is 14% only. at this time, when I run this command , after certain time I get following error.

  


  Is there any other fine tuning required on azure VM ?
