Any idea where we can get builds for Windows after this date?


I plan to provide 64-bit static builds starting the 18th. Will update 
doc with link once I make arrangements.

Re: [FFmpeg-user] Problem about duration value of converted mp3 file

2020-09-02 Thread myounggun jang
Thank you for your interest

The contents requested for confirmation have been retested and confirmed.
This is the result of recording a wav file on an Android device and
converting it on Windows PC.

The length of the original file is 26:39, and the result of converting it
to the default option is 25:47, which is displayed in Windows Explorer and
the file size is 4,686KB.
If this is converted using the -b:a 96k option, it has the same length as
the original 26:39 and the file size is 18,740KB.

I checked and played both the original file and the converted file using
ocenaudio SW, it marked as 26:39 and played.
However, the converted file by default is displayed in the time of 25:47 in
Media Player and played.

Below is the console output I tested.
I don't find any difference.

for the Enlightenment project, i have written a small tool to compile
from source its dependencies, including ffmpeg.

I provide no binaries, only a tool to compile ffmpeg and its dependencies

note that the tool compile only shared libraries

The FFmpeg project only provides source code, no builds.


An absolutely correct reply that doesn't actually answer the question asked. 
However, since the ffmpeg project _does_ list places to download pre-built 
versions (including zeranoe), it's rational to ask on this list.


Is anyone going to take up the task? The compute part is covered but I don't 
have sufficient space or bandwidth to serve as a build distribution platform.

http://ffmpeg.org/ffmpeg-codecs.html#ProRes

See bits_per_mb option. This is only for prores_ks encoder.

If you use another, the default prores (prores_aw) encoder, in that
case there is no any options to set,
and encoder happily writes files that may be a lot bellow or above
desired bitrate.

[FFmpeg-user] ffmpeg NVENC won't run

Next time specify what you actually tried.

qscale is not for reaching specific bitrate. It solely purpose is to
give you best quality under variable bitrate, whatever that means.

Hi,
I think i may be able to clear up the behavior of qscale
a little. According to https://trac.ffmpeg.org/wiki/Encode/MPEG-4
qscale behaves similar to the quantization parameter in h264.
That parameter is pretty well explained here:
https://www.pixeltools.com/rate_control_paper.html
but in short:
The quantization parameter basically tells an encoder
how much detail can be "thrown away" during encoding.
So if the parameter is lower, more detail is preserved,
if it's higher, more is thrown away, which leads to
a higher or lower bitrate respectively.

This is not the most detailed explanation,
but I hope it helps to clear up why a lower
number leads to a higher bitrate.

Hope that helps,
Valentin
