To convert a video file from one format to another format, the following command is used: ffmpeg -i yourvideoname.mp4 -c:v libx264 outputfilename.wmv. The command below is an example of when converting a .mp4 file into a .wmv file. 8. Join (merge) multiple video files. I need to convert about 1.5TiB or audio files which are in either flac or wav format. They need to be converted into mp3 files, keeping important meta data and the cover art etc. and the bitrate needs to be 320k. You can convert AAC to MP3, however, you will get slight loss of quality. You could use ffmpeg: ffmpeg -i inputfile.m4a -c:a libmp3lame -ac 2 -b:a 320k outputfile.mp3 To remove DRM: You can simply burn DRM-encumbered files to a CD and rip the CD to remove the DRM. The burn-rip is the easiest method, yet, you have quality loss. I tried your shown command (tested on Windows / commandline) : ffmpeg -i input.mp3 -codec:a libmp3lame -qscale:a 5 output.mp3 Result: It works for me.However the -qscale:a 5 makes FFmpeg decide on an average bitrate for you. Developers can take take advantage of JAVE to transcode audio and video files from a format to another. In example you can transcode an AVI file to a MPEG one, you can change a DivX video stream into a (youtube like) Flash FLV one, you can convert a WAV audio file to a MP3 or a Ogg Vorbis one, you can separate and transcode audio and video FFmpeg can be used to convert a huge WAV file into a tiny MP3 file that allows the user to listen to the same song but downloading just a portion of the original size of the WAV file. In this article, I will explain to you how to easily convert a WAV file to MP3 using FFmpeg from the command line. I have a folder with various media files such as .m4a, .aac, .mp4, etc. and I want to invoke FFMPEG to convert them all to .mp3 using the basic FFMPEG command ffmpeg -i myfile.m4a myfile.mp3. Can you show me a basic example of what this .bat text file would look like? I would like to iterate each media file using a type of wildcard so that it Unable to create aac/mp3 cbr 256k using ffmpeg. I am using following commands to make aac/mp3 files with 256kbps bitrate and constant bitrate mode. I need to make an aac file in CBR mode from a wav file. As per the documentation available at The app saves files in .mov format, with 2 audio channels. When I submit these files for transcription, they always come back with just one channel transcribed. I need to 1.) merge the tracks, and 2.) convert the .mov file to .mp3 format. Right now the command I'm working with is: ffmpeg -i input.mov -map 0:a output.mp3. In this tutorial, we saw how to convert an ogg audio file to mp3 on a Linux system. Using tools like ffmpeg or vorbis tools, as well as a slew of others, allows us to convert between these two codecs from the Linux command line.
