Adding qawanted wanted to see if we can reproduce this.

Following the steps provided, I'm unable to reproduce this green screen issue on the Flame device with 2.1 or 2.0 builds.

Questions:
Can you provide build information that you saw this issue on? 
Also did you see this issue happen on multiple videos? How many times was this bug seen?

I've tried 319mem and 512mem, Lock screen set to on and off with no luck.

I could repro this with an older video on my SD card but did repro this with a freshly recorded video

Repro Video Info:                No-Repro Video Infos: (newly taken video)
Length: 00:44                     00.49              00:10                      
Size 2.1MB                        36.3 MB            7.6 MB
Video Type: 3gpp                  3gpp               3gpp
Resolution: 352x288               1280x720           1280x720


Additionally - this should not be a blocking issue - the greenscreen is an oddity but not critical. It only persists until you restart the video or shuffle/shuttle-jog to a different frame than the last. 

This DOES repro in Flame 2.1, Flame 2.0, Open-C 2.1

Actual Results - Green screen seen on video when returning from Lock-screen

-------------------------------------------------------------------------

This bug partially repros on Flame 1.4

Actual Results - Upon unlocking the screen and returning to the video app the green screen is seen for a very brief flash and the video resets to timestamp: 00.00 (it also exhibits this behavior when pressing the homescreen button and then returning to the app).

------------------------------------------------------------------------------

This is a regression due to the lost behavior of auto-resetting the time-stamp to 00.00 on a video left on the final frame and returning to it.

This issue is occurred on multiple videos.
But some file was not occurred this issue.
When I try to reproduce this issue on recorded video files,
issue was always occurred.
(reproducible rate on recorded video file: 100 %)

Thanks.

*Update*
I was trying every time on videos set to Internal Memory. As soon as I switched the default storage to SDCard and recorded a new video, I was able to reproduce the Green Screen with any new videos.

Videos on Internal Memory seems to be void of this bug.
Videos on SD Card will repro this issue.

Comment 6

[Sotaro Ikeda [:sotaro]]

This bug seems similar to Bug 988030.

Comment 7

[Jaemin Song]

When I test this issue using some video files(not recorded video files),
problem is also occurred.

Comment 8

[Wayne Chang [:wchang]]

We can investigate this but this should not block.

Comment 9

[Sotaro Ikeda [:sotaro]]

It seems similar to Bug 988030. If codec outputs 0 as video out, it is a POVB problem.

Comment 10

[Wayne Chang [:wchang]]

Thanks Sotaro, marking accordingly.

I'll register issue to QCT SR.

Thanks.

Comment 12

[Jaemin Song]

I have confirmed this case again.
Sometime, although codec output is 0,
issue was not occurred.
zero size buffer seems not a root cause.
To confirm it,
if issue is reproduced,
please turn on/off screen repeatedly until video frame is shown.
In this time, buffer is also zero.

Please confirm problem again?

Thanks.

Jaemin, I am not sure what you said. It did not say that zero size buffer. I said that graphic buffer is filled with 0 data in Bug 988030 case. Did you checked it?

Comment 14

[Jaemin Song]

This issue seems not similar to Bug 988030.

I have checked problem again and found root cause.
When issue is occurred,
after EOS flag,if zero size buffer was come from decoder,
video frame was shown green image.
So, we modified "OMXCodec" code to control zero size buffer.

Thank you for your help.
