Renderingsprofil-prametre - Hvordan man læser dem

De parametre, som bruges i renderingsprofiler kommer fra programmet ffmpeg.

Dette er et gennemarbejdet eksempel som viser, hvordan du kan forstå hvad disse parametre betyder ved hjælp af ffmpegs dokumentation.

I eksemplet ovenfor er parametrene:

f=dvd 
vcodec=mpeg2video 
acodec=mp2  
b=5000k 
maxrate=8000k 
minrate=0 
bufsize=1835008 
mux_packet_s=2048 
mux_rate=10080000 
ab=192k 
ar=48000 
s=720x576 
g=15 
me_range=63 
trellis=1 
profile=dv_pal_wide 
pass=2

Søger du i ffmpegs hjælpesider så ser du at:

a main option is

-f fmt              force format

video options are

-vcodec codec     force video codec ('copy' to copy stream)
-pass n                select the pass number (1 or 2)
-b bitrate             set bitrate (in bits/s)
-vb bitrate           set bitrate (in bits/s)
-s size                 set frame size (WxH or abbreviation)
-me_range          <int>   E.V.. limit motion vectors range (1023 for DivX player)
-trellis                  <int>   E.VA. rate-distortion optimal quantization

audio options are

-acodec codec      force audio codec ('copy' to copy stream)
-ab bitrate             set bitrate (in bits/s)
-ar rate                  set audio sampling rate (in Hz)

The AVCodecContext AVOptions include:

-b                 <int>   E.V.. set bitrate (in bits/s)
-maxrate      <int>   E.V.. set max video bitrate tolerance (in bits/s)
-minrate       <int>   E.V.. set min video bitrate tolerance (in bits/s)
-g                 <int>   E.V.. set the group of picture size

So all the render profile options are documented here in the ffmpeg documentation.
