Black screen with video playback by using inputstream.adaptive with LineageOS 17.1 (Kodi 21RC1)

Hello @CastagnaIT @joseluismarti
I already had the problem in an older Kodi version as described here: #20639. With the fixes (#21421) it has worked since then. However, when installing the current Kodi version (21RC1) on an older environment (LineageOS 17.1 with Android 10), the problem occurs again for me.

Seems that the device is not returning any codec in getCodecInfos(), as several DVDVideoCodecAndroidMediaCodec::Open Testing codec... messages should appear in the log.

There has probably been an exception in a previous call, probably widevine, use adb logcat to display the system messages to see if it gives us any clues

To make sure that MediaCodec is working properly on this device, play a video locally and check that the above log messages are displayed.

Thanks for your tips @joseluismarti could the error possibly be because I didn't install GAPPS: https://opengapps.org/?arch=arm&api=10.0&variant=pico within my LineageOS environment? I use the “free” version Aurora-Store.

EDIT: I dug through the original issues (xbmc/inputstream.adaptive#771 and #20639) again and I found that the error pattern from back then is almost identical to the current one. The only difference: The test build with fix #21421 shown here #20639 (comment) was created based on arm64-v8a. The Raspberry 3 is still developed based on armv7a. Could it be that the previous fix in Kodi Core only works with arm64-v8a and not for armv7a builds?

It has nothing to do with GAPPS, it's related to the OS.

This fix was merged and is therefore included in v21, works fine with armv7/8 devices. Remains to be investigated what happens on rpi3

hi @joseluismarti , @CastagnaIT I have now created a logcat. I hope that it becomes clear where the error lies.

Hi, in this logs the string CDVDVideoCodecAndroidMediaCodec::Open does not appear. The logs from the start of Kodi until this call and after are of interest.

Ok @joseluismarti here is the 2nd attempt...
lineage_171_new.txt

[joseluismarti]

Try this build, I've caught possible exceptions and added some debug message. Post a comment only with logs containing the string CDVDVideoCodecAndroidMediaCodec .

Note that installing this apk will cause you to lose your current Kodi configuration.

Ok @joseluismarti her it is:
lineage_171_debug.txt

EDIT: additionally the complete kodi.log (debug)
kodi_lineage171_debug.log

[joseluismarti]

Another test, ignore the result of DecoderFilterManager...

Great job @joseluismarti !!! With the new test version and Lineage 17.1 with the Rpi3 the output of the streams now also works. Attached is the kodi.log.
kodi_lineage17_debug2.log

EDIT: Can you briefly describe what caused the error @joseluismarti ? Will there be a PR for this too?

Kodi uses a configuration file (decoderfilter.xml) to control which decoders should be used to play and which should not by passing the video hints.

xbmc/xbmc/cores/VideoPlayer/DVDCodecs/Video/DVDVideoCodecAndroidMediaCodec.cpp

Lines 771 to 772 in ac32937

	if (!CServiceBroker::GetDecoderFilterManager()->isValid(m_codecname, m_hints))
	continue;

It seems that all decoders that are available on this device (OMX.google.*) are disabled for this content.

xbmc/xbmc/platform/android/media/decoderfilter/MediaCodecDecoderFilterManager.cpp

Lines 26 to 28 in ac32937

	static const char *blacklisted_decoders[] = {
	// No software decoders
	"OMX.google",

Manually activate a decoder (OMX.google.h264.decoder) by editing the file [userdata]/decoderfilter.xml, restart kodi and check if the modified configuration has taken effect.

Ah ok @joseluismarti so I always have to manually adjust the decoder.xml on my Raspberry Pi 3 to make it work?!
