Stagefright

30 posts in this topic

Posted (edited) · Report post

I keep hearing stagefright this, stagefright that, but what exactly is it?

I hear that its disabled in most roms, i believe that's because its broken? and thus the high quadrant score (which skips tests) which are actually not a true representation of performance?

What does stagefright do?

What is it useful/used for?

I hear some people say it helps increase smoothness of playback with divX's, games etc when its enabled even though its broken so how can it improve performance?

Can it be fixed?

Is it worth enabling it on RSL7JJ Rom etc?

Sorry for the questions but i'm sure it would benefit other users too, as there seems to be myths floating about too.

Cheers

LOL, copy and pasted from: http://developer.android.com/sdk/android-2.2-highlights.html

I was looking for a better answer(s) but thanks anyways.

Ok :

Stagefright is ment to improve performance.

However the implmentation on the blade gives double the score in benchmarks for Quadrant - this makes us suspect that its broken.

However some users say some games are better with it on.

Thats it really

But are you sure its broken?

my friend has SGS and he got 950 quadrant on 2.1 and over 1500 on 2.2 so thats about 600 points more

im getting 580 on 2.1 and over 1100 when stagefright enabled so its about 600 more

so we both have about same improvement in points

to be fair i am not sure, in my r3 rom i turned it on and just played a divx and it played perfectly, so i have a feeling it handles divx code well, but and its a big but, it needs more experimenting with and feedback because i have not yet tried with stagefright off or on 2.1 eclair as yet

That's not a real score as Quadrant and stagefright in 2.2 do not play well together. When Quadrant gets to the h264 part of the tests it blips and thinks the test has completed immediately which results in a hugely inflated score as it thinks the device was powerful enough to complete the test in 0 seconds.

So is it broken in SGS too or why did he get so much more points after updating to 2.2?

Yup, it is pretty much broken for every device running 2.2 and fixed in 2.2.1.

Ok but is it bad to have it enabled? quadrant doesnt show right points but is there anything else bad it does or is there something good it does?

In my experience the broken stagefright in 2.2 can mess with the colours and adds a green bar to the top in Youtube videos. Stagefright is also a bit more CPU intensive than Opencore. Pretty much the only reason to keep stagefright on in 2.2 is to show off an incorrect Quadrant score.

Do you specifically have "media.stagefright.enable-http=true" set in build.prop as well as the other stagefright settings? otherwise you may be using opencore for Youtube. Some users have reported that stagefright has approx 10% more cpu usage in decoding h264 compared to opencore.

ro.com.google.clientidbase.ms=android-zte

media.stagefright.enable-player=true

media.stagefright.enable-meta=false

media.stagefright.enable-scan=true

media.stagefright.enable-http=false

net.bt.name=Android

dalvik.vm.stack-trace-file=/data/anr/traces.txt

my setting that seem to work well

i will turn everything on tomorrow and seee if i get a differance, but remember that it will flow through to player i bet when http is off, and opencore is over ridden, thats what the source seems to feel to me but i could be incorrect.

It does not 'flow through' to player, with those settings you will be using opencore for Youtube.

The Word Highlighted suppose to be True on a normal Build. I remember with the early roms when we had a problem with green bar on youtube someone came up with a solution to disable stagefright on "Player" from "true" to false". However we noticed that in doing so it lowered the quadrant score to approx half. So we changed it back and instead disabled it on "http" which managed to keep the incorrect inflated score on quadrant.

You have to leave http false and change the other ones to true. It should look like this:

media.stagefright.enable-player=true

media.stagefright.enable-meta=true

media.stagefright.enable-scan=true

media.stagefright.enable-http=false

Setting true to http will give you a green bar on HQ yoochoob ;) videos. Also if you have stagefright enabled I saw that it solved some problems with gameloft games that crashed when starting them with the message: Video can not be played.

I think KK said it tricked the game into thinking you could play the videos, so it made it let you play the game.

Use search before losing so much time for nothing. Flash is not compatible with the ARM6 processors we have in our sanfrans.

realised its nothing to do with flash so i am forgetting that avenue, its to do with heap sizes, dont actually think stagefright s broke, will upload new rom tomorrow after i have altere a couple of things and i have tested youtube and it works perfectly in hq with no green bar, i just want to test more in the morning and then upload to you guys. will check quadrant score as well because i know what i got with settings previous, but i can say what i have tried so far seems to run really smooth and fast. dont know impact on battery thou to be fair, but time will see on that front.
