MediaCodec error

[ddicaro]

Content description

On many old devices that use OMX.MTK.VIDEO.DECODER.AVC decoder when try to play a MPEG-DASH stream on Akamai CDN with DRM we receive this error: I think this issue is linked to others that are marked in your code inside the MediaCodecVideoRenderer.class class (e.g # 3835, # 3236, # 3355, # 3439 etc ..). Inside the switch of method protected boolean codecNeedsSetOutputSurfaceWorkaround(String name) of class MediaCodecVideoRenderer.class adding, for example, the code of the wiko fever the media is playing correctly. We encounter the same error on many devices of our users (see attachment reportErrorDrmWithDevice.pdf), which clearly we have no chance to test. We wanted to know if you can test them and / or add them to the switch in the code

Can you please provide a bug report as described here?

About the other devices, do you have a stack trace? Do you have access to the device names (see 3rd column of https://support.google.com/googleplay/answer/1727131?hl=en-GB)?

[ddicaro]

I sent an email with the two required files like attachements. I don't have full stacktrace access, I only have the information in the file (now there is also device name)

[kim-vde]

Sorry but this is not the kind of bug report that I need. Please generate the bug report with adb bugreport (as described here).

I don't see the device name in the csv file you sent. Note that it is not the same as the device model.

[ddicaro]

I got the file (bugreport.txt) with add bugreport command (see screenshot). I have also attached the screen taken from Android studio. Are there any other information you need?

Unfortunately in my analytics system at the moment the android.os.Build.DEVICE is not present but only android.os.Build.Model. Is there a way for this information to be sufficient?

The command you should execute is adb bugreport, and not add bugreport. Where did you attach the screenshot?

[ddicaro]

I sent an email to dev.exoplayer@gmail.com. Yes, the command that I executed is adb bugreport. Inside message the automatic corrector changed the value writed

We will add your device (l5460) to the workaround list soon.

For the other devices, we don't have the resources to test them. Therefore, as they haven't been tested, we will add the devices that meet the following conditions: 1) The device can be uniquely identified from the model name; 2) There is already a device in the list in codecNeedsSetOutputSurfaceWorkaround with same brand and similar marketing name.

The only device from the list you provided that meet those conditions is the one with model name JSN-L21.

[ddicaro]

Just to clarify, having the android.os.Build.DEVICE would be enough for you to add other devices, or there also have to be another device with same brand and similar marketing name in the list?

[kim-vde]

There would need to be another device with same brand and similar marketing name, as those devices have not been tested. Having the Build.DEVICE would probably allow us to add more devices, as we would be able to uniquely identify them (using the Build.DEVICE and Build.MODEL).
