How do I access the MediaMetadataRetriever.setDataSource(…) status codes?

问题:

I'm getting the following error java.lang.RuntimeException: setDataSource failed: status = 0xFFFFFFEA and I'd like to know what this status is. I'm using the function MediaMetaDataRetriever.setDataSource(String filePath)

回答1:

I got this error java.lang.RuntimeException: setDataSource failed: status = 0xFFFFFFEA when tried to call void setDataSource(String path) on an empty file. (0 bytes)

You need to be 100% sure that path for the file is not null, not empty, the file itself exists and valid.

回答2:

It was very well buried but I found the source. Here is a link to the error codes

It's a build from ICS and I'm not sure where it is in the current build.

My error was a not supported error when I used a midi file.

回答3:

I got this error: setDataSource failed: status = 0xFFFFFFEA because the file does not exist on my device.

回答4:

I'm catch this error when my audio file was brocken, it solved when I change file, you can try manually set different sources paths
