Vladimir :
Try to use react-native-ffmpeg\n\nI had the same task. I solved it by using this module: https://github.com/tanersener/react-native-ffmpeg.\n\nAfter installation, you can use it like this: \n\nimport { RNFFmpeg } from 'react-native-ffmpeg';\n\nRNFFmpeg.execute('-i imageFilePath -i audioFilePath -c:v mpeg4 output.mp4');\n",
