Is it possible to convert FFmpegFormat object or FFmpegStream object value to Map?

[DongJu-Na]

Here is my code.

This code seems to generate an error while converting the variable value of Fraction type in the FFmpegStream object. I want to receive video information as a map. Any good way?

     public HashMap<String,Object> getVideoInfo(String fileName) throws IOException {
         HashMap<String,Object> result = new HashMap<String, Object>();
         ObjectMapper objectMapper = new ObjectMapper();

         FFprobe ffprobe = new FFprobe(ffprobePath);
         FFmpegProbeResult probeResult = ffprobe.probe(uploadPath + fileName);

         FFmpegFormat format = probeResult.getFormat();
         HashMap<String, Object> fResult = objectMapper.convertValue(format, new TypeReference<HashMap<String, Object>>(){});
         System.out.format("%nFile: '%s' ; Format: '%s' ; Duration: %.3fs", 
            format.filename, 
            format.format_long_name,
            format.duration
         );

         if(fResult != null) {
             result.putAll(fResult);
         }

         FFmpegStream stream = probeResult.getStreams().get(0);
         HashMap<String, Object> sResult = objectMapper.convertValue(stream, new TypeReference<HashMap<String, Object>>(){});
         System.out.format("%nCodec: '%s' ; Width: %dpx ; Height: %dpx",
            stream.codec_long_name,
            stream.width,
            stream.height
         );

         if(sResult != null) {
             result.putAll(sResult);
         }

         return result;

     }

You need to tell the Jackson object mapper about the fraction type.

I actually have a really old example of this here: https://github.com/bramp/jackson-datatype-commons-lang3/blob/master/src/test/java/net/bramp/jackson/lang3/FractionTest.java

Thank you for your answer. I don't really understand with that code Can you explain it in detail? 😥

[bramp]

I haven't used this code in a long time, but if you do something like:

mapper.registerModule(new LangModule());

It will tell your object mapper how to decode/encode fractions

Thanks, I put that code in and the error went away. Is this library dependent vulnerability safe? It is difficult to confirm without knowledge Can you answer me one more time?
