amr NODATA and other issue

Post by liberamor » Mon Jul 01, 2019 10:06 am

Hello, i'm Gianni and i'm new to ffmpeg.
I'm sorry if the topics i go to explain it has been still explained, and i'm sorry for my troubled english too.
i have some problem using the ffmpeg. My application it need to convert amr audio files into wav, and mix the files to rebuild a conversation.
the amr audio silent packet is a NODATA.
when i execute the command "ffmpeg -i silent.amr silent.wav" i have those errors:

[amrnb @ 000001d892881a00] Corrupt bitstream
Error while decoding stream #0:0: Invalid data found when processing input

It seems the library can't recognize the amr silent NODATA (0x7c)

Another thing i have to ask is that: i use the ffmpeg program in a system shell from my c project.
I would like use the library into the program, to have control of errors i have using the library.
how to understand what i have to include and how to use it in a c visdual studio program??

Thanks
Gianni
