Failed to convert any image file to a jpeg one using FFMPEG-CodePudding

I'm trying to convert any image that is selected to a jpeg file, but my command keeps saying at least one output must be specified, this is the ffmpeg command

const selectImage = async () => {
const result = await launchImageLibrary({
      mediaType: 'photo',
      selectionLimit: 1,
    });
const tempPath = RNFS.TemporaryDirectoryPath   'uri.jpeg';
if (result.didCancel || result.assets.length === 0) return;
try {
    FFmpegKit.executeAsync(
        '-i '   result.assets[0].uri   ' -c:v '   tempPath
      )

I've look into many of the documentation with react native but i can't find a specific one in regards of converting only images, nor the packages specify it since the multimedia options given as packages are audio or video.

CodePudding user response：

the issue you're having is that -c:v doesn't have a parameter attached to it and instead thinks your output file is the encoder you're trying to use.

Either remove the -c:v option entirely, or run ffmpeg -encoders and choose one from the list (eg: -c:v libx264)
