NumberFormatException For input string: "N/A" about jaffree HOT 5 CLOSED

Could you provide ffprobe output? Actually the message you provided is only a warning, the result is the same: null.

from jaffree.

Also you can implement your own converter and directly use methods of DBase subclasses:
stream.getSection().getValue(key, yourOwnConverterToRatio)

from jaffree.

not a warn, when use fastjson cast to string, JSON.toJSONString( stream );

from jaffree.

Did you include Fast JSON? Jaffree doesn't need it. Could you provide working sample with error?

from jaffree.

just for log info
use SerializerFeature.IgnoreErrorGetter sovled
log.info(JSON.toJSONString(stream, SerializerFeature.IgnoreErrorGetter));
