  • ffmpeg shell script globbing

    10 novembre 2015, par AD0AE

    I have a pretty straight forward question. I have a bunch of individual directories that are labeled as ./001 ./002 ... ./201
    within each directory contains files that have the identifier *_IO.PNG

    I can use the shell command : ffmpeg -framerate 20 -pattern_type glob -i './066/*IO.PNG' -c:v libx264 -pix_fmt yuv420p 066.mp4 and this works great. It does exactly what I want.

    However, I tried to write a shell script, which is below but this does not work. It seems to be loading individual files instead of all of them at once. Any help would be appreciated.

     #!/bin/bash
    
 for i in {1..5}
    
 do
    
   FILE=$(printf %03d $i)
    
   echo " This file: $FILE"
    
   infile='./$FILE/*IO.PNG'
    
   echo $infile
    
   ffmpeg -framerate 20 -pattern_type glob -i $infile -c:v libx264 -pix_fmt yuv420p './$FILE.mp4'
    
 done

  • FFMPEG - What are some recommended parameters for x265 (libx265) ?

    7 janvier 2019, par dd_code

    I am working on re-encoding some footage (x264), including some grainy footage. I am interested in CRF-only bitrate management (I want to avoid artifacts during demanding scenes).
    What are recommended parameters to be set instead of leaving them at their defaults ?

    Here is what I got so far, pretty simple :

    ffmpeg -i in.mkv -vf unsharp=3:3:1 -c:v libx265 -tune:v grain -crf 24 -c:a copy out.mkv

    (this example has grain tune as many files are grainy, and without it it washes it out and all the "detail by noise" is lost + I am applying a light sharpening filter, I find there is always a room to sharpen a bit without causing noticeable sharpening artifacts)

    If I am not mistaken all the params one does consider are ones contained in the presets, but is there some other or one of those which is a good practice to adjust manually to achieve a better result ? I was wondering specifically about P,I,B-frames and AQ (but I guess there are some other as well).

  • avcodec/nvenc : unregister input resource when unmapping

    avcodec/nvenc : unregister input resource when unmapping

    Currently the resource is only ever unregistered when the
    
registered_frames array is fully in use and an unmapped entry is re-used
    
and cleaned up.
    
I'm pretty sure the frame will have been cleaned up before that happens,
    
so I'm kinda surprised this never blew up.
