I've compiled the ffmpeg for iOS with the instructions from FFmpeg-iOS. I am trying to use it for wav to mp3 conversion with the help of FFmpegWrapper. It gives me the following error: Invalid audio stream. Exactly one MP3 audio stream is required. Did anybody has the same issue?

Edit:

The code I am trying to use for the converting

NSString *inPath = [[NSBundle mainBundle] pathForResource:@"record" ofType:@"wav"];
NSString *outPath = @"/Users/someuser/Desktop/out.mp3";

FFmpegWrapper *wrapper = [[FFmpegWrapper alloc] init];
[wrapper convertInputPath:inPath outputPath:outPath options:@{kFFmpegInputFormatKey: @"wav", kFFmpegOutputFormatKey: @"mp3"} progressBlock:^(NSUInteger bytesRead, uint64_t totalBytesRead, uint64_t totalBytesExpectedToRead) {
    NSLog(@":)");
} completionBlock:^(BOOL success, NSError *error) {
    NSLog(@"Complete");
}];

You're trying to store an AAC stream in a MP3 container, would be my guess. Either store the result as `"${i%.mp3}-ENCODED.aac"` or switch `-c:a aac` to `-c:a libmp3lame` – Ali Jun 09 '17 at 10:12
I've seen here on stackoverflow this answer, but my issue is that I cannot use the ffmpeg from command line. How can this be done from code? – Infinite Possibilities Jun 09 '17 at 11:06
whats your trying code? – Ali Jun 09 '17 at 11:59
@combo_ci I just added my code as an edit of the post. – Infinite Possibilities Jun 09 '17 at 12:15
I think you must search for how to configure FFmpegWrapper software...FFmpegWrapper must have a file or a configure menue that you could change ffmpeg setting..or are FFmpegWrapper use last version of ffmpeg? – Ali Jun 09 '17 at 12:19
for example see the answer of [link](https://stackoverflow.com/questions/30912542/mp4-to-hls-using-ffmpeg) he change duration of hls in a configuration od FFmpegWaper – Ali Jun 09 '17 at 12:22
I am going to check this, thanks! – Infinite Possibilities Jun 09 '17 at 12:44
I think you gave me a good hint. It takes time until I fully check it, but I will return with an answer. – Infinite Possibilities Jun 09 '17 at 12:46
