ExoPlayer crashes on DRM protected contents with IMA ads

[baiqindotfubotv]

This crash is 100% reproducible with DRM protected contents with IMA ads. Right now it only happens on my Pixel 2XL android 11. I also found a way to reproduce with ExoPlayer demo app:

(1) Check out to r2.15.0
(2) Add a sample to media.exolist.json:

{
        "name": "HD (cenc)",
        "uri": "https://storage.googleapis.com/wvmedia/cenc/h264/tears/tears.mpd",
        "drm_scheme": "widevine",
        "drm_license_uri": "https://proxy.uat.widevine.com/proxy?provider=widevine_test",
        "ad_tag_uri": "https://pubads.g.doubleclick.net/gampad/ads?sz=640x480&iu=/124319096/external/ad_rule_samples&ciu_szs=300x250&ad_rule=1&impl=s&gdfp_req=1&env=vp&output=vmap&unviewed_position_start=1&cust_params=deployment%3Ddevsite%26sample_ar%3Dpremidpost&cmsid=496&vid=short_onecue&correlator="
}

(3) Open that sample from demo app, wait for preroll to finish, the playback will crash after 15 seconds.

This sounds like a duplicate of #8696 but there isn't quite enough information in the provided logcat snippet to be sure.

Can you either provide a full adb bugreport or look for the following output in logcat:

E/SurfaceUtils: Failed to connect to surface 0x71e621ca70, err -22
E/MediaCodec: nativeWindowConnect returned an error: Invalid argument (-22)

If it is a duplicate of that issue then you may be able to fix the problem using MediaItem.Builder#setDrmSessionForClearPeriods(true), but it won't work in all cases (see #8696 for more details). There are some other possible (more invasive) workarounds detailed in #8696 (comment).

@icbaker Yes I see the following error before the stacktrace:

2021-10-28 08:22:10.343 14914-17678/com.google.android.exoplayer2.demo E/SurfaceUtils: native window cannot handle protected buffers: the consumer should either be a hardware composer or support hardware protection

2021-10-28 08:22:10.385 14914-17663/com.google.android.exoplayer2.demo E/MediaCodecVideoRenderer: Video codec error

Also using setDrmSessionForClearPeriods(true) doesn't solve the issue. The difference is that without the option the crash happens right before the first midroll. With it the crash happens right after preroll.

This is likely because the ad has different decoder requirements to the content, so the decoder has to be re-initialized when transitioning from the pre-roll to the content, even though both are secure decoders: #8696 (comment)
