(Core :: Audio/Video, defect)

Attachment: logcat_20150402_1457.txt

Description:
The song time runs too fast (about 2x fast). This will cause it to jump, stutter, and skip seconds. (The time, not the music). The track time will complete before the song is over causing the music app to advance to the next song and end the current song before it is fully played. 
This occurs playing music through the device speaker and through a plugged in headphones; but this issue does NOT repro when playing through a Bluetooth Headphones. 


Repro Steps:
1) Update a Flame to 20150402103013
2) Launch Music App
3) Play a song

Actual:
Song time runs too fast, causing music to end prematurely

Expected:
Time will run on a 1-1 ratio, as usual

[Blocking Requested - why for this release]:
Functional regression, fails smoke test as we can't listen to a song in it's entirety.

Requesting a window.

[No-Jun Park [:njpark]]

ni?ing hub for insight.

Comment 4

[No-Jun Park [:njpark]]

Hema, tomorrow is Canadian holiday so both me and :hub probably won't be available, but it is a ST blocker so the bug causing patch needs to be backed out asap, once it is identified view regression range check.  ni?ing you for possible help with contacting the devs.

Comment 5

[David Flanagan [:djf]]

This is almost certainly a gecko regression. Nothing has changed in the Music app itself in the last few days.  Needinfo Anthony, since this is probably a bug for his team.

Brogan: does this happen for all music, or only certain types of music? If this only affects mp3 files (but not .mp4 and .ogg, for example) then I'd guess that it is somehow related to https://www.mozilla.org/en-US/security/advisories/mfsa2015-31/ and bug 1106596 (which I don't have access to read).

Comment 6

[David Flanagan [:djf]]

Needinfo for Jim, too, since as No-Jun points out, Hub probably won't be working tomorrow.

Comment 7

[Hema Koka [:hema]]

See comment 5. Lets get the regression range 

Both Dominic and Hub will be out tomorrow because of holiday in Canada and Taiwan. If there is any help required on the app side, please ping Jim Porter. 

Thanks
Hema

This does not repro with the .ogg music file (http://upload.wikimedia.org/wikipedia/en/4/45/ACDC_-_Back_In_Black-sample.ogg)

Issue appears to have been caused by changes made in bug 1139206

Comment 11

[KTucker [:KTucker][Inactive 3/4/2016]]

Sotaro, can you take a look at this please? Can we get the landing for bug 1139206 backed out since this is a smoketest blocker?

Comment 12

[Sotaro Ikeda [:sotaro]]

backed out is OK for me.

Comment 13

[Jim Porter (:squib)]

Sounds like this is well in-hand; clearing NI for me.

Comment 14

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

back out in the bug that caused the regression:
https://bugzilla.mozilla.org/show_bug.cgi?id=1139206

Marking as fixed.
