When changing video tracks in Live + Dash + DRM Widevine + HEVC Media the first 2 seconds frame are pixled

I am playing live dash drm hevc media on the demo app with the following bitrates: 384000, 560000, 920000, 2200000, 4520000

when track selection is done manually I can see that the first frames are not fluent and pixels are shown

when I run this media on Android TV I do not see this issue on tracks selection but on mobile device it is happening.

when I perform track selection using the dialog for example to 920000 i can see in the logs the following: I am not sure whether it is the decoders of the hevc/ stream encoding/ drm or the player please advice.

I have investigated this issue some more I can tell that this issue behaviour was not there on v2.9.6 and first observed on v2.10.0

I think this information is a good starting point for understanding the root cause.

this behavior is in production and we would be happy if this can be prioritized by the team

Regarding the c2.android.* decoder.

Could you tell why this is happening there and how to workaround this without hacking the code? should we open issue for Android Platform?

If I apply the below code then I have the playback working (though audio is not playing the c2.android audio decoder seems not to be working on my Pixel1/android 10 and there is only one decoder coming from MediaCodecUtil for “audio/mp4a-latm” on this device

renderersFactory.setMediaCodecSelector((mimeType, requiresSecureDecoder, requiresTunnelingDecoder) -> {
            List<MediaCodecInfo> codecsList =  new ArrayList<>(MediaCodecUtil.getDecoderInfos(mimeType, requiresSecureDecoder, requiresTunnelingDecoder));
            ListIterator<MediaCodecInfo> iter = codecsList.listIterator();
            while(iter.hasNext()){
                String name = iter.next().name;
                if(name.startsWith("OMX.google") || name.startsWith("c2.android")) {
                    iter.remove();
                }
            }
            return  codecsList;
        });
