Still using Opus (with libopus) encoder, tho.

fixed, but I guess the Fraunhofer people forget to remove the warning
it seems.

Thanks for the info.
I'll use Opus from now on.

I was converting flac audio to aac_lc with libfdk_aac with VBR encoding.
But I saw a message about VBR encoding.
The command and output of the command is as follows :
Command :
ffmpeg.exe -i input.flac -c:a libfdk_aac -afterburner 1 -frame_length 1024
-cutoff 0 -vbr 5 -profile:a aac_low
But, in case of SVT-AV1, x264, and x265, we can see progress, but, idk why
not in case of vpx and aom-av1.
Anyways, fine enough.

Even after waiting like 5 mins, I saw the same status as the output of the

ahead ?

okay.
thank you sir.
But, I had one more problem coming frequently while encoding in two-pass.
The problem says `File Ended Prematurely`.
What could be the reason for this frequent issue ?

In words of Gyan Dev Sir, a maintainer of FFMPEG,
"Two-pass is meant for when you have a fixed input and you wish to analyze
the file beforehand, so that the encode is optimized for the target bitrate
and other encoder parameters.
Your 1st command is discarding the capture. And so your 2nd
`-rc 1` in SVT encoders i.e SVT-AV1, SVT-VP9, SVT-HEVC means VBR encoding.
So, when I just set the Target Bitrate, like .eg `-b:v 5000k` does this
mean the encoder will use VBR encoding with an average bitrate of 5 mbps or
is this Average Bitrate Encoding (ABR) ?
Is it possible to trigger VBR mode by setting different values for
-maxrate, -minrate and -b:v even for those audio codecs who doesn't have
support for VBR ?
e.g mp2 doesn't have VBR support in ffmpeg, but it supports bitrates from
32 to 384 kbps. So, if I set -minrate to 32k, -maxrate to 384k,

I was testing libx265 encoder and I was that when psy-rd is enabled for 444
input, the quality is halved.
Here are my encoding settings:
# Video capture encoding settings
cap_soundcommand "ffmpeg -f s16le -ar %s -ac 2 -i - -c:a aac -profile:a 1
-q:a 2.0 -y temp_a.nut"
cap_videocommand "ffmpeg -f
I was encoding with VBR native FFMPEG's AAC encoder i.e using `-q:a.`
https://trac.ffmpeg.org/wiki/Encode/AAC
The above page says that effective range for -q:a is `0.1 to 2.0.`
But, I tried to encode with `-q:a 5.0` and FFMPEG didn't gave any error for
encoding the audio. I was suprised!
And I

I saw I missed '-' after null so it was giving me an error.

I was trying to calculate VMAF of two mkv videos. One is lossless and
second is lossy.
I tried to gave this command :
ffmpeg -i outputvideo.mkv -i lossless.mkv -lavfi
libvmaf=log_path=output.xml -f null -
But it didn't work. So, how can I calculate the VMAF scores of two mkv
videos ? Can anyone

Okay, I founded out the alternative for calculating VMAF. I wanted to ask
you that is libvpx-vp9 with -lossless 1
oops sorry:
dsda-doom.exe -timedemo nameofdemo -viddump video.mp4
this was the command sorry for the mistake.

I viddump videos with help of FFMPEG through `Video Capture Encoding
Settings` of DSDA-Doom.
A demo (also called LMP, from the lump file extension) is any recording of
a game session that can be played back using the game engine. Internally,
it is a sequence of tic commands, keeping track of just

Is this VBR encoding, is `-b:a 128k` the average bitrate or maximum/minimum
allowed bitrate ?

I have an Intel Pentium G3240 processor.
This is a quite a low end processor and even x264 etc is cpu-intensive and
even encoding with this encoder is really slow. (6.0 to 6.5 fps with medium
preset).
I encoded some videos with mpeg4 video encoder and h264_qsv encoder. The
results I got was the
