That command starts by setting a variable with the name of your audio file. Then it runs the ImageMagick "convert" command to create a label with that filename centered on a 720x480 canvas. The output is forced to PNG format and piped into ffmpeg as the video input. After your audio file is read in, ffmpeg uses "filter_complex" to run the video
I have a lot of wav files (each with respective names) that need to be converted from wav to mp3 and I have been trying to write a batch file to do this. I'm using the latest nightly build of ffmpeg on Windows 10 Insider build. I've looked through the ffmpeg documentation but can't find anything on this. I developing android application, Where I've asked to record the calls and convert them to WAVE(.wav) format and send to server. I am able to successfully record and save the audio in my mobile. The recorded file mime type is 3gpp, now I want to convert this 3gpp file to wav. I tried using FFMPEG but unable to convert it. yOAPar.
