Re: [FFmpeg-user] A VisualStudio solution to build the libraries

2021-03-07 Thread Chris Miceli
From a security point of view that sounds incredibly dangerous to use
someone's pre built binaries. Whilst time consuming, setting up well should
only be an hr or two of work but the client/your company will be able to
trust the libraries.

To answer the original question I don't have the DLL files hanging around
and most builds I've seen are 64bit these days

No, not yet. Still hoping to find a simpler/quicker way of getting the 
libraries we need. It's a one-off for us.
Hard to imagine that there is no one out there who has the DLLs, or can just 
build it for us, as a favour.

Thanks!

[FFmpeg-user] A VisualStudio solution to build the libraries

2021-03-07 Thread Zolotarev, Michael
Good people

Does anyone have a VisualStudio solution to build FFMPEG libraries?

For our application the x64 libraries aren't suitable, need x32 or AnyCPU. 
Tight deadline, having a .sln would help immensely. Or maybe someone has AnyCPU 
build which you can share?

Much appreciated

ffmpeg -lavfi 'sine,aformat=sample_fmts=u8,aformat=sample_fmts=fltp' -f null -

... obviously yes.

See this list for questions about the API:
https://lists.ffmpeg.org/mailman/listinfo/libav-user/

And if you expect help, you need to provide a modicum of information.

[FFmpeg-user] swr_convert from packed to planar

2021-03-07 Thread Livio Tenze
Dear all,

I am trying to use the swr_convert function to convert (format and
resample) an audio stream with dual channels from AV_SAMPLE_FMT_U8
to AV_SAMPLE_FMT_FLTP.

The problem is that the samples, after calling swr_convert, are all zeros.
I checked the source samples and they differ from zero.

885->0.00

875->0.00

855->0.00

993->0.00

878->0.00
Is it possible to use swr_convert to resample and convert audio
samples from AV_SAMPLE_FMT_U8 to AV_SAMPLE_FMT_FLTP?

Thanks in advance.
