  • Convert WAV to AIFF with ffmpeg

    12 novembre 2016, par Arete

    How 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.aif will 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

  • 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.

    


  • Python Wifi Issue Connect to Mysterious Camera

    27 avril 2015, par user2723463

    I have been working with some drones and robotics projects using arduino and python. There was a kickstarter project for a neat little hex copter, that hasn’t been managed well.

    I was lucky, i got my copter and then some time later after some frustrated email exchanges, i finally recieved the camera as well. To this day, their forum has people still complaining. Their maker forum is now down and their wiki hasn’t been updated with any specifics on the camera.

    http://www.flexbot.cc/wiki/index.php?title=Main_Page#Hardware

    Their app to accompany the drone still doesn’t support the camera module. Not that it’d matter, as their code isn’t very well documented or annotated.

    https://github.com/HexAirbot

    There are some tips on switching the camera on the comments page of their kickstarter campaign.

    https://www.kickstarter.com/projects/1387330585/hex-a-copter-that-anyone-can-fly/posts/1093716

    So, sob story over, i’m stuck with this neat little wifi camera that i am unsure on how to connect to. I know how to switch it on and it does have a micro-usb port on it.

    What library in Python could i use to stream an image from this camera given that it is a wifi camera. If i wanted the video stream as a numpy matrix.

    I need to interface with the camera, so i can connect and disconnect.

    Then, be able to read images frame by frame with ffmpeg. I have some python modules that can detect and read from a camera, but how can my code ensure that the camera is connected ?

    Totally stuck. Any help would be appreciated.
