This is how I got cross compiling to work (from a mac to pc … how’s that for a cross).įirst, I built the mingw32 tools for the Mac. Some additional resources that helped me greatly along the way:

In case you’ve had issues following the previous section, you can download my already updated folder or jump directly to building it: You should have everything ready now to rebuild the debian package. Mingw32-runtime (3.15-1) unstable urgency=lowĪlternatively you can download my version:

Now before we rebuild, we need to update the change logĮdit it so that the top now refers to new version 3.15: Now you should have only 2 tars in the folder: Now remove the old stuff so that it doesn’t get confused: We need to untar the downloaded files, rename the exported folder and re-tar so that the debian build is happy. Unfortunately, the paths are not correct and you need to change a few things. You need to go to the MinGW download site and download the 3.15 MinGW runtime and 3.13 Win32 API tar files. Next we want to update with the latest MinGW sources: This should download 3 files in your current directory:Īnd create the mingw32-runtime-3.13 folder. First, we need to download the 3.13 sources:

So, I am going to show you how to upgrade it to 3.15 now. The latest and greatest mingw runtime debian package is 3.13. So what versions do we have installed you say? You end up with this error most likely:ĮRROR: MinGW runtime version must be >= 3.15. Unfortunately, it would be too easy, right. configure –target-os=mingw32 –cross-prefix=i386-mingw32msvc. Since I already had setup a Debian as a VM running inside VMWare Workstation for compiling FFmpeg on Linux, I figured I’d go that way.

You can set up MinGW on Windows or you can install it on a Linux box as a cross-compiler. To compile FFmpeg for Windows, the recommended way is to leverage MinGW. I figured others would have issues too so here’s a quick summary of my experiments. Compiling for Linux and Mac is pretty straightforward, however for Windows, it’s not that easy. Simple, and fast.Lately I have been trying to look into compiling ffmpeg for windows/mac/linux as a standalone executable. You can manipulate the video from the original FLV if you want, fool around with the bitrate, sample rate and number of channels.Īnd maybe you’ll want to learn that later, but for now you know one thing with certainty: it’s simple to use FFmpeg to extract audio from a file in FLV format. You can transcode the audio to a different format, for uploading to a cell phone, MP3 player, or WAV file. Of course, FFmpeg has many, many other options available.

Just open it up in your favorite media player and give a listen to make sure everything is as it should be. acodec copy – copies the audio track (instead of encoding to another format)īohemian_Rhapsody.m4a – name of the output fileĪfter typing the previous command, only a second or so should go by, and you should notice a new file on your Desktop, named Bohemian_Rhapsody.m4a, which will contain nothing but the original audio track from the original FLV file. vn – tells FFmpeg to ignore the video track i Bohemian_Rhapsody.flv – provides FFmpeg with the name of the input file Here’s what the different parts of the previous command do: Knowing this, all we need to do is type the following command: For extracting purposes, we’re most interested that the file has AAC audio. In order, it tells us that the stream is encoded using the AAC encoder, that it has a frequency of 44100 Hz (the correct sampling rate for burning to CD), that it is stereo, uses 16-bit samples, and has a bitrate of 107 kb/s. The above information tells us the following things. The part we’re interested in will look something like this: Because along with the error, it also gives us information about the file. When we hit Enter after the command, we haven’t told ffmpeg exactly what to do with the file, so it spits out an error. What we’ve actually told ffmpeg is that Bohemian_Rhapsody.flv is the input file. The above command is a bit of a hack, and you’ll get errors, but don’t worry. Note: if you’re trying this along with the tutorial, substitute the name of your file each time you see it used in the commands.

Now that we’ve used cd to change directory to the Desktop, we need to type the following command: This is important because if you tell a program (like FFmpeg) to act on a file, only the file isn’t where the Terminal is “looking” then you will get errors. This moves the Terminal program into the same directory (the Desktop in this case), so all of our commands will be active there. In our example, the file is called Bohemian_Rhapsody.flv and it is located on the Desktop. To do that, open the Terminal (if it isn’t still open), and change to the directory where the FLV file is located. The first thing we need to do is find out exactly what codecs are used in our FLV file.
