Hello,

I ran into an error when using Fmod API in Android system.

I’ve been trying to play MP3 files, which are saved in the server, directly from url, and I downloaded all the mp3 files in a legal way(I paid for them). While I could play some of them without any problem, there has been errors shown for some files.

The first log is when mp3 files are played properly.

The second log is when the error occurred(mp3 files are not played due to errors)

03-28 14:22:39.501 6205-6205/com.example.ysj.recommendingmusicplayer I/fmod: SystemI::createSoundInternal             : filename = http://27.102.206.204/music/Ariana%20Grande-Problem%20(Feat.%20Iggy%20Azalea).mp3 : mode 00000089

As you can see from the second log, the error is shown as FMOD_ERR_FORMAT or FMOD_ERR_FILE_EOF. Since all of them are files of mp3 extension, I think there shouldn’t be any problem in terms of format.

Could you any please tell me the reason why?

Thank you so much!

There is a large amount of tag data at the start of your MP3 file that is failing.

Are you able to remove that from the file?
That would allow it to load correctly.

My test didnt get this problem, can you copy the netstream example code and add this before your createsound call

result = system->setStreamBufferSize(64*1024, FMOD_TIMEUNIT_RAWBYTES);

Sometimes if the chunk of data isnt read into memory fully at the start, it might execute a seek instruction. This results in FMOD_ERR_FILE_COULDNOTSEEK with a netstream.
The reason it might try to seek is because it has ID3V2 tags in the file at the start, and they’re large.

If that doesn’t work try FMOD_IGNORETAGS and FMOD_MPEGSEARCH. Let me know how you go.

I really appreciate your help!

I have modified the code and tried it as what you’ve advised, still the same error occurs.

(modified code)

result = system->setStreamBufferSize(512*1024, FMOD_TIMEUNIT_RAWBYTES);
result = system->createSound(“http://27.102.206.204/music/Ariana%20Grande-Problem%20(Feat.%20Iggy%20Azalea).mp3”, FMOD_IGNORETAGS | FMOD_MPEGSEARCH | FMOD_CREATESTREAM | FMOD_NONBLOCKING, 0, &sound);

The difference is that it used to show the error log right after CreateSound, but now it runs for a short period of time and the error is now shown as ‘Fatal error (14) scanning the codecs. (i.e. not FMOD_ERR_FORMAT or FMOD_ERR_FILE_EOF)’.
