openCV 2.4.10 lost cinepak radius codec
28 octobre 2014, par user3652747I am working on a Windows 7 64 bit platform.
Before :
I was using OpenCV 2.4.6, compiled by myself with CodeBlocks and a MinGW compiler. When recording a video, I was able to select the Cinepak Radius Codec (CVID) and all my world was shinny. I don’t remember tweaking a lot the configuration of CMAKE when creating the CodeBlocks project to compile OpenCV.Now :
I download the last stable version OpenCV 2.4.10 and I have to use this one. So I applied the same recipe : CMAKE, CodeBlocks project, compile. But then I cannot choose the Cinepak Radius Coded while creating a new video.Questions :
Did the Codec disappears from OpenCV or did I miss one flag in the CMAKE configuration ?Of course I tried other config, but to me, I just had to activate WITH_FFMPEG and WITH_VFW flags. Do you have any tips on that ?
Thanks !

Normalize audio, then reduce the volume in ffmpeg
27 octobre 2014, par Steve SheldonI have a question relating to ffmpeg. First here is the scenario, I am working on a project where I need to have some audio with a presenter talking and then potentially some background music. I also have the requirement to normalize the audio. I would like to do this without presenting a bunch of options to the user.
For normalization I use something similar to this post :
How to normalize audio with ffmpeg.
In short, I get a volume adjustment which I then apply to ffmpeg like this :
ffmpeg -i <input /> -af "volume=xxxdB" <output>
</output>So far so good. Now let’s consider the backing track, it doesn’t want to be the same volume as the presenters voice, this would be really distracting, so I want to lower that by some percentage. I can also do this with ffmpeg, I could do it like this (example would set volume to 50%) :
ffmpeg -i <input /> -af "volume=0.5" <output>
</output>Using these two commands back to back, I can get the desired result.
My question has two parts :
- Is there a way to do this in one step ?
- Is there any benefit to doing it in one step ?
Thanks for any help !
