FFmpeg : building example C codes
23 février 2021, par J. S.I have configured and compiled the FFmpeg library using this link :
https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu



Now, I am trying to build example C codes provided by FFmpeg from here :
https://github.com/FFmpeg/FFmpeg/tree/master/doc/examples



However, when I run make install-examples or make install (suggested by /example/README), I receive this kind of message :





make : *** No rule to make target '/doc/examples/README', needed by
 'install-examples'. Stop.





I thought this may be due to the rules not being in the correct MakeFile format (I am not sure why they refers to README). How should I go about in fixing this and compiling the example codes ? I have tried to find solutions about this, but there doesn't seem to be much information online.



Thank you.

12 novembre 2016, par AreteHow can I convert a wav file to an AIF file with ffmpeg ?
I need to make various files one in 16 Bit, one in 24 bit and one in 32 Bit.
I also need to make different sample rates. E.g one in 176,400 kHz and one in 44,100 kHz.
I know
ffmpeg -i input-file.wav output-file.aifwill convert the file but I am not sure about the rest.https://www.ffmpeg.org/general.html#Audio-Codecs says ffmpeg supports AIFF but there is no documentation on the AIFF encoding : https://en.wikipedia.org/wiki/Audio_Interchange_File_Format#AIFF-C_common_compression_types
