| Summary | 0006243: Some MP3 tracks show Length 0:00 although WMP shows the correct length | ||||
| Description | I uploaded one mp3 track to our FTP ( /MMbugs/bug6243/03 - With You In Me [Silentstressor RMX].mp3 ). If the track is played in MM then player shows e.g. 0:50/0:00 i.e. length of the track is reported incorrecly as 0:00 If the track is played in WMP then it correctly shows 3:53 | ||||

The problem seems to be in the Xing header - StreamSize field, the indicated length is 793ms, but the expected length (from the file length) is 233s. I've tried MediaInfo software and it shows length 793ms too. WMP maybe ignores the StreamSize field and prefers expected length from the file length. MM prefers the minimum of DataLength (from StreamSize) and ExpectedDataLength (from file length). |

Hmmm, I thought that it is something like this. I think that MM should be smart enough as WMP and iTunes and correctly guess that the DataLength (from StreamSize) value is incorrect by comparing the value with ExpectedDataLength (from file length). i.e. if (DataLength/ExpectedDataLength < 0.9) or (ExpectedDataLength/DataLength < 0.9) then Length = ExpectedDataLength else Length = DataLength |

Ok, although it's a little questionable whether we should report the same length as WMP (the stream header is apparently corrupted), let's make the suggested fix. I'd just change the constant to something like 0.75, so that the other value is only used when the compared values are way too different. |

Fixed in build 1301. Now the track length is computed from file length, if the StreamSize is less then 75% of expected value. |
