I am compressing movies from bitmaps and audio files. With AAC files it is working correctly. But when I have AMR_WB files sound is corrupted. I can recognise correct words in video file but it is delayed and with very bad quality.
My AMR files are recorded with parameters: - sampling rate: 16000, - bitrate: 23000. I am setting this parameters in audio stream which is added to video. Sample format is set to AV_SAMPLE_FMT_FLT. When using other formats app crashes with "Unsupported sample format". What needs to be done to correctly add AMR stream to video file? Do I have to reencode it to AAC and add as AAC audio stream?? Thank you for all hints.
