Edwin, can you see if you can duplicate this on your One X?
QA Contact: eflores
Assigning to Chris to follow up once there are (hopefully) STR and logs from a device. Anything we track for 17 at this point must have an assignee so if you're not the right person, please hand off to another person who is not 'nobody'.

Assuming this is a hw decoder problem given the GPU comment.. The plan is to land Bug 806369 (create a blacklist) to deal with this blocker issue here for Firefox 17. The root cause fix will addressed after Firefox 17.

(In reply to Mark Finkle (:mfinkle) from comment #6) > Aaron - Can you still reproduce this bug? If so, could you show it to Kats? Yes (TF201, CM10 (4.1), Nightly 11/01).
I still can't seem to reproduce this bug. I installed a recent CM10 build (cm10-20121026-unofficial-tf201) and nightly (11/05). Quitting Fennec while playing the video clip did not produce a crash.
We're at the stage in 17 beta cycle where we won't be able to take any more speculative fixes so it looks like this will have to remain unfixed in 17.

It seems that bug 806369 will partially take care of these crashes, except for Samsung devices (18.5% of crashes) that are whitelisted for StageFright on ICS.
Jim can't reproduce, bouncing back over to Chris

I don't have a device to test this on so can't reproduce either.
Despite the Samsung device whitelisting for StageFright in 17.0b5, it still happen on non-Samsung devices and is currently #2 top crasher in 17.0b5.
I suggest blocking the devices that are crashing until someone gets a device they can reproduce on. Was an answer made to comment 10: "Who is responsible for the blocking of devices to prevent SW & HW decoding crashes?" I assume the android team.
(In reply to Chris Double (:doublec) from comment #15) > I suggest blocking the devices that are crashing until someone gets a device > they can reproduce on. As said in comment 14, they still crash despite the blocklisting for StageFright decoding on ICS for all devices except Samsung ones.
(In reply to Scoobidiver from comment #16) > (In reply to Chris Double (:doublec) from comment #15) > As said in comment 14, they still crash despite the blocklisting for > StageFright decoding on ICS for all devices except Samsung ones. If they're crashing, they're not blacklisted. This is because blacklisting prevents loading the code that crashes. Therefore either these devices are not blacklisted or the blacklist is broken.

Either way, this sounds like a new (separate) bug against the patch in Bug 806369 until we know more. In terms of who would "own" that, doublec is correct: the Android folks with the help of bjacob own implementing & debugging the blacklist code (i.e. making sure that devices get blacklisted/whitelisted correctly).

Is there a way to tell if these crasher have stagefright.force-enabled turned on? Unlikely but would be good to knpw.
(In reply to Chris Double (:doublec) from comment #21) > Is there a way to tell if these crasher have stagefright.force-enabled > turned on? Unlikely but would be good to knpw. There isn't a way at the moment, but it's easy to add such an annotation in AppNotes (also telling if Stagefright was used at all during a session, and whether it was successfully initialized or failed/denied). That's what ScopedGfxFeatureReporter does. Patch coming.

A few remarks / questions. 1. The crash reported linked in comment 0, https://crash-stats.mozilla.com/report/index/39be186f-0e74-4a5e-ae82-53e532121017 is on Android 4.1: Android API Version 16 (REL) That certainly explains why blacklisting is not taking effect there: we explicitly don't blacklist stagefright on Android 4.1 and newer, which we identify by the Android API Version being >= 16. Note that in the OS Version field, this crash report *lies*: it mentions version 4.0.3. That shouldn't be trusted, then. So, do we know how many of the crashes discussed here are on Android API Version 16 and newer? Unfortunately, the crashdata CSV files don't have Android API Version. Because of the above-mentioned inconsistency between Android API Version and the OS Version string, I don't know if I can trust the version numbers in comment 20. Do you know how these version numbers are obtained? 2. Here is a breakdown of recent crashes with Android Model/Hardware/Product/Manufacturer strings, suitable to establish blacklist rules: $ cat a.csv | grep libstagefrighthw.so@0xca3 | sed

Hopefully recent enough. 3. Next steps: - need to know if the problem is that we should blacklist Android 4.1 devices, or if the problem is that we fail to blacklist Android 4.0 devices. See above point 1.; this is pretty much blocking everything else. - If we need to add more Android 4.1 blacklist rules, we need to construct such rules from the data in above 2.; for that we need to find factors in that table that have a strong correlation with this crash.

(In reply to Scoobidiver from comment #29) Thanks, that saves me time! So we've been talking with Brad and think that we should try finding the actual Android version instead of the Android API level; looking into that now.
Requesting review from 2 people as I suppose that we're time-constrained with the impending realization of the Mayan prophecy. Joe for GfxInfo aspects, Brad for Android aspects. This patch makes us use Build.VERSION.RELEASE instead of Build.VERSION.SDK_INT. I don't know for sure that this will have the correct value on the devices that we have this crash on; but it *should* from the 'os version' strings we see in the crash reports. Testing needed. A little complication was that OperatingSystemVersion() really wants to return an integer, not a string; so we make up an integer by mashing together 8-bit version number components. Thankfully SplitDriverVersion exists, doing the parsing for us.

This is how we'll know if people force-enabled stagefright in a crash report; will also confirm if stagefright was used at all, and whether it was blacklisted.

So the 3rd and last thing we need to do here is blacklist the devices that are actually running Android 4.1+ and are still crashing. Here's a query from CSV files (accumulated crash data from Dec. 10 to Dec. 19, so 10 days) filtering only Android 4.1+ crashes, by parsing the 'os version' string which actually seems to work well enough: bjacob:~/crash-stats$ cat a.csv | grep libstagefrighthw.so@0xca3 | grep \\:4\\.1\\.[0-9]\\/ | sed 's/^.*\(Model[^|]*\)|.*$/\1/g' | sort | uniq -c | sort -rn 383 Model: A500, Product: picasso, Manufacturer: Acer, Hardware: picasso' 97 Model: K1, Product: cm_k1, Manufacturer: Lenovo, Hardware: ventana' 76 Model: AT100, Product: unknown, Manufacturer: TOSHIBA, Hardware: antares' 47 Model: Ideapad K1, Product: k1, Manufacturer: unknown, Hardware: ventana' 46 Model: A500, Product: full_a500, Manufacturer: Acer, Hardware: picasso' 41 Model: A501, Product: full_a501, Manufacturer: Acer, Hardware: picasso' 36 Model: A500, Product: full_a500, Manufacturer: Acer, Hardware: ventana' 28 Model: a200, Product: picasso_e, Manufacturer: Acer, Hardware: picasso_e' 27 Model: Malata SMBA1002, Product: drh_smba1002, Manufacturer: unknown, Hardware: harmony' 23 Model: Transformer TF101, Product: full_tf101, Manufacturer: asus, Hardware: ventana' 20 Model: tervigon, Product: tervigon, Manufacturer: Motorola, Hardware: harmony' 20 Model: HTC One X, Product: tg_endeavoru, Manufacturer: unknown, Hardware: endeavoru' 18 Model: A501, Product: full_a501, Manufacturer: Acer, Hardware: ventana' 11 Model: Notion Ink ADAM, Product: aokp_adam_3g, Manufacturer: unknown, Hardware: harmony' 9 Model: Notion Ink ADAM, Product: cm_adam_3g, Manufacturer: unknown, Hardware: harmony' 7 Model: Notion Ink ADAM, Product: full_adam_3g, Manufacturer: unknown, Hardware: harmony' 7 Model: Malata SMBA1002, Product: full_smba1002, Manufacturer: Malata, Hardware: harmony' 7 Model: Iconia A500, Product: full_a500, Manufacturer: Acer, Hardware: picasso' 7 Model: GT-I9103, Product: GT-I9103, Manufacturer: samsung, Hardware: n1' 6 Model: SGH-T989, Product: SGH-T989, Manufacturer: Samsung, Hardware: harmony' 5 Model: Notion Ink ADAM, Product: cm_adam, Manufacturer: unknown, Hardware: harmony' 5 Model: Iconia A500, Product: full_a500, Manufacturer: Acer, Hardware: ventana' 5 Model: GT-I9100, Product: k1, Manufacturer: unknown, Hardware: ventana' 3 Model: GT-P7510, Product: full_GT-P7510, Manufacturer: samsung, Hardware: p3' 3 Model: BRUNO P.

So it looks like the right way to blacklist this stuff is really by the 'Hardware' field, as this give relatively few blacklist rules to cover most devices, and very high correlations with this crash. Let's first check compute the overall prevalence of this crash: bjacob:~/crash-stats$ cat a.csv | grep libstagefrighthw.so@0xca3 | grep 'Android' | wc -l 2969 bjacob:~/crash-stats$ cat a.csv | grep 'Android' | wc -l 418370 bjacob:~/crash-stats$ echo "scale=5;2969/418370" | bc .00709 So 0.7 % ( = 0.007) of our Android crashes have this signature (over past 10 days). Now let's compute the prevalence of this crash for the 'Hardware' values giving it, filtering only the ones that gave at least 10 crashes over the past 10 days: bjacob:~/crash-stats$ cat a.csv | grep libstagefrighthw.so@0xca3 | grep \\:4\\.1\\.[0-9]\\/ | sed 's/^.*Hardware\:\ \([^|]*\)|.*$/\1/g' | sort | uniq -c | sed 's/^\ *//g' | grep ^[0-9][0-9] | cut -d ' ' -f 2 > hardwares bjacob:~/crash-stats$ cat hardwares | (while read FOO; do echo -n "$FOO : " && echo "scale=5;(`cat a.csv | grep libstagefrighthw.so@0xca3 | grep "$FOO" | wc -l`/`cat a.csv | grep "$FOO" | wc -l`)/0.00709" | bc; done) antares' : 6.14245 endeavoru' : 2.19322 harmony' : 87.33004 picasso' : 25.92383 picasso_e' : 11.47531 ventana' : 20.97884 These numbers tell how many times you are more likely than the average to have this crash, if you have a particular 'Hardware' field. So all of these Hardware's are strongly correlated to this signature, from 'endeavoru' that is at 2.19 times over-represented to 'harmony' that is at 87 times over-represented. So we just have to add blacklist rules for these 'Hardware' fields. Let's get this added as downloadable blacklist entries to get this deployed to users asap... filing bug.
Depends on: 824118
Filed bug 824118 for the blocklisting request.
My above computation was slightly flawed as 1) in computing overall prevalence I didn't restrict to Android 4.1+ and 2) in the hardware listing I took only Android 4.1 and not 4.2. Corrected computation for android 4.1 and 4.2: bjacob:~/crash-stats$ cat a.csv | grep libstagefrighthw.so@0xca3 | grep 'Android' | grep \\:4\\.[12]\\.[0-9]\\/ | wc -l 958 bjacob:~/crash-stats$ cat a.csv | grep 'Android' | grep \\:4\\.[12]\\.[0-9]\\/ | wc -l 101160 bjacob:~/crash-stats$ echo "scale=5;958/101160" | bc .00947 bjacob:~/crash-stats$ cat a.csv | grep libstagefrighthw.so@0xca3 | grep \\:4\\.[12]\\.[0-9]\\/ | sed 's/^.*Hardware\:\ \([^|]*\)|.*$/\1/g' | sort | uniq -c | sed 's/^\ *//g' | grep ^[0-9][0-9] | cut -d ' ' -f 2 > hardwares bjacob:~/crash-stats$ cat hardwares | (while read FOO; do echo -n "$FOO : " && echo "scale=5;(`cat a.csv | grep libstagefrighthw.so@0xca3 | grep "$FOO" | wc -l`/`cat a.csv | grep "$FOO" | wc -l`)/0.00947" | bc; done) antares' : 4.59873 endeavoru' : 1.64202 harmony' : 65.38225 picasso' : 19.40865 picasso_e' : 8.59134 ventana' : 15.70644 So now, 'endeavoru' is only at 1.6 over-representation, that borders on not being enough to warrant blacklisting. By default I'll still maintain the blacklisting request. Other values are still well into the range where blacklisting is a no-brainer.

Comment on attachment 694579 [details] [diff] [review] Use the Android version RELEASE string, instead of the SDK_INT number [Approval Request Comment] Bug caused by (feature/regressing bug #): We run into these system crashes since we do H264 decoding User impact if declined: Android top-crasher on many android 4.0 devices (pre-4.0 devices are correclty blacklisted; 4.1+ devices still crashing are handled separately in bug 824118) Testing completed (on m-c, etc.): just landed Risk to taking this patch (and alternatives if risky): doesn't seem too risky, but I admit it's nontrivial code, it does things with stack arrays, etc. So it has a nonzero risk (of, say, crashing). That said, I've written the code carefully and tested it carefully too. String or UUID changes made by this patch: none

Comment on attachment 694579 [details] [diff] [review] Use the Android version RELEASE string, instead of the SDK_INT number We understand this to be risky to consider approving for our final beta's as per the risk analysis in comment 39.We will wontfix this for Fx18 and resolve the issue in Fx19 with the aurora landings.

Summary: We are still seeing crashes in 4.0+ and earlier to a volume level that seems like the patch is not making a dent into the crash rate. details : the bug was pushed on the 22nd; looking at this there is at least 17 crashes after the 22nd build: https://crash-stats.mozilla.com/report/list?range_value=14&range_unit=days&date=2012-12-31&signature=%400x0%20|%20libstagefrighthw.so%400xca3&version=FennecAndroid%3A20.0a1 The OS looks like a custom OS build (not Android, but Cynogenmod or otherwise) on 4.0
Re: comment 43: that's interesting. Clicking on the reports, I see 2 kinds of reports: Case #1: Manufacturer: asus, Hardware: ventana Example: https://crash-stats.mozilla.com/report/index/36f04183-3d17-44f2-8662-59d9f2121230 Since this has 'Hardware: ventana', it will be blocked by bug 824118 anyway. It should be blocked by the current code though; I don't understand why it's not. Case #2: Manufacturer: samsung, Hardware: p3 Example: https://crash-stats.mozilla.com/report/index/f33031eb-6173-44fc-8931-041fb2121230 For this one, there is a clear reason why it's not blacklisted by the current code: we are explicitly whitelisting 4.0 devices with 'Manufacturer: samsung'. Perhaps we should not; or perhaps we should blacklist those that have 'Hardware: p3'.

I lost track of this bug; re-reading the comments here, it seems that we are just waiting for bug 824118 to be fixed?
(In reply to Benoit Jacob [:bjacob] from comment #49) > I lost track of this bug; re-reading the comments here, it seems that we are > just waiting for bug 824118 to be fixed? I believe so, yes. I'm going to bring up the fact that QA needs to test bug 824118 as part of today's channel meeting.
Given the fallout from bug 824118, and a lack of in-product fix, we won't be able to resole for FF19.
status-firefox19: affected → wontfix
As this led to bug 838845, I suspect we will not get to this for FF20 but will leave it tracked for now so it stays on our radar.
At this point we will untrack and leave it with the graphics team to decide on either making bug 824118 version specific or work on bug 838845 since we can't use the current blocklist.

Note that those crashes might have replaced Flash crashes. If it's a one-to-one or less than that, I don't think gfx blocklisting (allows again Flash) is the right solution.
Scoobidiver, does that mean that you have seen Flash in all the affected stacks you checked?
(In reply to Robert Kaiser (:kairo@mozilla.com) from comment #55) > Scoobidiver, does that mean that you have seen Flash in all the affected > stacks you checked? I see libflashplayer.so loaded in some crash reports (correlations per module don't exist for Fennec) but I though StageFright decoding was meant to replace Flash for some kinds of videos where both Flash and HTML5 video contents are proposed. So if videos crashes both with Flash and HTML5, disabling StageFright decoding won't change the volume of crashes, only makes them hidden behind NP_Shutdown.
