+++ This bug was initially created as a clone of Bug #909243 +++ The bug is created based on Bug 909243 Comment 12. g_128orig.mp3 should have duration of 30 seconds only but it will be show as 41 seconds. So when player is playing at 30 seconds then player will end to play. I confirmed the symptom on today's v1.2 and master hamachi.
Summary: [Nexus 4][Android 4.3][music] unable to play the song (.mp3) via music app → [music] duration of mp3 is not correct
By applying the patch, the duration of g_128orig.mp3 became correct. mozilla::MP3FrameParser seems not work correctly.
Most recent master seems to fix the problem. - gecko: e55ebbb92007b838189d067ca398a8f81c5a1436 But the problem is still present on v1.2. From it, Bug 922334 seems to fix the problem. attachment 812945 [details] [diff] [review] in Bug 922334 seems to fix the problem. It blocks mp3 file parsing before AudioTrack is created in OmxDecoder::TryLoad(). Within TryLoad(), ProcessCachedData(0, true) is called. TryLoad() and OmxDecoder::NotifyDataArrived() code might request mozilla::MP3FrameParser to count mp3's length as overlapping.
Even when applied attachment 812945 [details] [diff] [review] to v1.2, the problem was not fixed. The patch seems not related to this bug.

The MP3 frame parser should keep track of the offset up to which it has parsed the file. There have been some major changes to the parser recently in bug 910996. You might try to revert attachment https://bugzilla.mozilla.org/attachment.cgi?id=799915 to go back to the old version.
Is this happening on all mp3 files or something specific to one file.
(In reply to Hema Koka [:hema] from comment #5) > Is this happening on all mp3 files or something specific to one file. Is the above could be checked by using various mp3 files?
Some of the MP3's I've had bad durations reported on include: http://people.mozilla.org/~cpearce/vbr.mp3 (duration 2:00, *still* reported as 34s by MP3FrameParser). http://nxt-level.com/music/02.%20everlast%20-%20black%20jesus.mp3 MP3s from http://folkradio.ru/nagrani/ http://nxt-level.com/music/DJ%20Shadow%20feat.%20Mos%20Def%20-%20Six%20Days.mp3 There are others too.
Here are my findings: Testing on m-c gecko, the issue is not replicable. g_128orig.mp3 from test_media/music in Comment 0 shows duration as 30 sec and play for 30 secs Build Id:20131015040202 OS Version 188.8.131.52-prerelease Gecko mozilla-central : c079fe98d21fc2c24dbf333d1341855c9280f3d0 Gaia master: f5c2e987fcc859e371fedb44006ca94fc0ebcb28 On gecko v1.2 the issue is replicable, g_128orig.mp3 from test_media/music shows duration as 41 sec and play for 30 secs Build Id:20131015040202 OS Version 184.108.40.206-prerelease Gecko mozilla-aurora : 292baf182d8778772335fd2f6fa84eb82e31b906 Gaia master: f5c2e987fcc859e371fedb44006ca94fc0ebcb28 Testing mp3 files in Comment 7, shows correct duration on both v1.2 and v1.3. This is a gecko issue, as confirmed by Sotaro in Comment 8 and should be fixed by landing mozilla-aurora fix of bug 919572 in v1.2
Since we have the fix on master, it will be fixed in 1.3 not blocking this for 1.2
blocking-b2g: koi? → 1.3+
(In reply to Hema Koka [:hema] from comment #10) > Since we have the fix on master, it will be fixed in 1.3 > > not blocking this for 1.2 Confused. The bug Sotaro references that fixes this issue affects 1.2. And the above discussion talks about this reproducing on 1.2. And this is likely a regression as well. Can you clarify?
Jason, We are able to reproduce this in 1.2. However, it does not affect the audio output of the mp3. The issue is only on the duration being displayed and the movement of the slider to the end once the 30 sec mark is passed. Mp3 plays correctly. Given that input, we did not mark it a blocker during the bug traige meeting. However, I just tested this on my Leo which has an old version of 1.1 and the duration is displayed correctly for the test mp3 file g_128orig.mp3 -- so this probably is a regression issue. Can you please confirm. We can then re-evaluate if we need to mark this a blocker.
Sure. QA Wanted - Can someone check if this reproduces on 1.1?
The bugs doesn't reproduce on Leo 1.1 MOZ RIL, MP3 files show correct duration time Device: Leo 1.1 MOZ RIL BuildID: 20131018041205 Gaia: 39b0203fa9809052c8c4d4332fef03bbaf0426fc Gecko: 7fedb6a967ea Version: 18.0 Firmware Version: US_20130912
That confirms this is a regression. And based on cpearce's comments, there's multiple mp3 files affected. A music player isn't exactly all that useful if it's displaying the playback duration incorrectly. Renom.
blocking-b2g: 1.3+ → koi?
marking this a blocker - regression issue
blocking-b2g: koi? → koi+
When Bug fix: https://bugzilla.mozilla.org/show_bug.cgi?id=919572 lands on 1.2, this fix can be verified and and closed
Hema, since the dependent bug 919572 has been landed...do we just need to verify and close this bug?
yes, that's correct (in reply to Candice's comment 18) Thanks Sotaro for adding qawanted flag.
Can be closed, seems to work fine on 10/28 Buri aurora build - music plays exactly the time as it's showing for the file duration (tested with MP3 files from comment 7) Gaia 2ef9bc3c7a6de228b63e6ba3613eb0c0dd639c59 SourceStamp 4a94d2ea9d37 BuildID 20131028004002 Version 26.0a2
