• FFMPEG Invalid Option [duplicate]

  16 août 2022, par misteralexander

  Per the suggestion from mklement0 I have shortened the output here to just the relevant code and error. Additionally, as he pointed out, I have changed how I am constructing the arguments (now passing as an array).

  


  Additionally, the comment from kesh, I removed the "-filter_complex" and changed to just several "-map" 's.

  


  $TEMPDIR = "E:\MediaConversions\BitLadder"
$FOLDER = 'White.Boy.Rick.2018.1080p.WEB-DL.H264.AC3-EVO'
$OUTPUTDIR = $TEMPDIR + '\' + $FOLDER

# Mux the 8 Bitrate Ladder steps into a single file, with a common audio stream
$STEPS = @(Get-ChildItem -Path $OUTPUTDIR -Name)
$INPUT_FILES = @()
$MAP = @()
$COUNT = 0
ForEach ($STEP in $STEPS){
    $INPUT_FILES += ('-i', "$STEP")
    $MAP += ('-map ' + "$COUNT" + ':v', '-map ' + "$COUNT" + ':a') 
    $COUNT++
}

$OPTIONS = ('-' + "$INPUT_FILES", "$MAP")
#$OPTIONS
D:\Applications\ffmpeg\bin\ffmpeg.exe "$OPTIONS" -f matroska "E:\MediaConversions\White.Boy.Rick.2018_MultiStreamTest_AAC.H264.mkv"


  


  But Sadly, I still get the same frustrating error :

  swr : move compensation_distance handling to swri_resample caller.
  I think there’s an off-by-one in terms of the switchpoint where we
  
  switch from dst_incr to ideal_dst_incr, I don’t think that’s a massive
  
  issue, but just be aware of that. It’s probably trivial to prevent but
  
  I don’t care.

• How to use ffmpeg to upscale video resolution with libplacebo ?

  30 juillet 2023, par Ironbox

  In Vapoursynth, it is convenient to download and use plugins to change the frame rate of videos. However, it seems that using FFmpeg has more limitations (or maybe I haven't found the right method). Anime4K is a video enhancement algorithm suitable for anime and similar videos. In MPV, their plugins can be imported and used for real-time frame rate conversion.

  


  In FFmpeg, how can I use the algorithms in glsl files to change the video frame rate, instead of using FFmpeg's built-in algorithms ?

  


  In FFmpeg, i can use libplacebo filters can also be used to apply GLSL shaders. In my tests, using command like :

  


  libplacebo=custom_shader_path=Anime4K_Upscale_CNN_x2_VL.glsl


  


  this leads to noticeable GPU usage, but the output video resolution remains the same as the original.

  


  I can pass in the w and h parameters when calling the libplacebo filter :

  


  libplacebo=w=iw*2:h=ih*2:custom_shader_path=shaders/Anime4K_Upscale_CNN_x2_VL.glsl


  


  This achieves the purpose of super resolution, but is it essentially using anime4k for upscaling behind the processing ?
Is it using the upscaling algorithm in libplacebo first, before applying anime4k ? How can I achieve my original goal that only use anime4k to upscale ?
here's my full command (in python) :

  


  [
    'ffmpeg -hide_banner',
    '-hwaccel', 'cuda',
    '-i', '"{input_ab_path}"',
    '-filter_complex',
    '"[0:v]libplacebo=custom_shader_path=libplacebo=custom_shader_path=shaders/Anime4K_Upscale_CNN_x2_VL.glsl,subtitles="{sub_file}":si=0[out]"',
