• FFmpeg UHD encoding (piping to x265)

  15 décembre 2016, par TEB

  Update based on the good answers :

  Source :
  Prores HQ 4:2:2 10bit
  4kp25
  REC:2020

  Heres my syntax now :

  ffmpeg -pix_fmt yuv422p10 -i JUNGLES_PLUTO_UHD_HDR_HLG.mov -pix_fmt yuv420p10 -f yuv4mpegpipe - | x265 --y4m - --input-res 3840x2160 --fps 25 --preset veryslow --b-adapt 2 --ref 4 --no-open-gop --keyint 50 --min-keyint 50 --no-scenecut --profile main --level-idc 5 --no-high-tier --sar 1:1 --colorprim bt709 --transfer bt709 --colormatrix bt709 --bframes 3 --hrd --vbv-bufsize 25000 --bitrate 25000 --vbv-maxrate 25000 --aud --no-info --b-pyramid -o test.h265
  
  
  
  output: Option pixel_format not found.

  rec:709

  • Question 1 : How does one pipe correctly from ffmpeg to x265 ?
  • Question 2 : How can one make sure the cpus are all taxed ? I have
    16vcores, but im getting like 2-3% usage on all
  • Question 3 : Any suggestions on the parameters to increase the
    quality ?

  • Question 4 : Since the content is BT2020, but my target device is not currently able to display/render BT2020, but BT709.. how would i change the syntax to enable this in the best way..(downscale it)
    Would :

    —colorprim bt2020 —transfer bt2020 —colormatrix bt709

  be correct ?

• FFMPEG and MSA1 Codec Issues when Converting WMV to MP4 Video

  30 décembre 2023, par user136819

  I have a WMV video file (around 60 MB size, 01:23:00 length) and I'm running a Windows Server 2016 64-bit machine for testing.
  
As far as I know, this video file was recorded using Microsoft Live Meeting 2007 back in April 2010 and there is also an associated audio file (which I'm able to play).

  


  I tried to play the video file on my machine using VLC player (latest update), however, I always see this weird MSA1 codec error :

  


  

  


  So I tried to resolve this problem by downloading and installing the Combined-Community-Codec-Pack-64bit-2015-10-18, and using its MPC-HC 64-bit player to play the video...
I still couldn't get it to play ! Here are the logs shown by the MPC player :

  Since that didn't work, I tried installing the Microsoft MPEG-4 V1/2/3 VKI Codec for ASF files and still couldn't get the players to play the video and saw the same errors as above !

  


  As a final attempt, I tried to convert this video to MP4 format using FFMPEG (version from 2020). Even this failed. Here are the logs :

  I wish to know, is there any other way I can convert this video to a more modern format so that I can play it on a modern machine and modern video player ?
  
What other codecs am I missing here ? (if so, where can I get them ?)
  
FYI, as mentioned earlier at the top, I'm only able to play the associated audio file...

  


  I'm fairly new to all this stuff, so any help is appreciated.

  


  Thanks in advance ! :)

  


• setPTS outputting wrong duration (Ffmpeg)

  16 septembre 2020, par WebDiva

  I have a video of duration 14 seconds. I applied the setPTS filter to make it 3 times slow. So the total duration should be 42s (14*3). But the output gives a 49s long video. Here is the command :

  


  ffmpeg -i video.mp4 -filter_complex "[0:v]setpts=3*PTS[v];[0:a]atempo=0.6,atempo=0.5[a]" -map "[v]" -map "[a]" output.mp4


  


  What is wrong with this command ? I tried it for different videos but all has the same weird issue. Any help will be appreciated. Regards.
