Can reproduce. Could be https://chromium-review.googlesource.com/c/chromium/src/+/1132569 but it's weird it doesn't reproduce on https://youtu.be/1OMjBQrBq5k  will take a look Monday, but rbd in case it is that change.

Hmm inconsistent repro actually even on the link in #0.

How frequently so you see this issue?

Can't reproduce again, so dropping to RBB pending further reports.

Just saw it again, may be config change related:

video decoder config changed midstream, new config: codec: h264 format: 1 profile: h264 main coded size: [1280,720] visible rect: [0,0,1280,720] natural size: [1280,720] has extra data? false encryption scheme: Unencrypted rotation: 0°

100% reproducible, visible on other sites (for example now I observe it on wykop.pl), related to last Chrome changes, not device or OS version.

Thanks. Definitely looks like my change and seems midstream config change related. Will double check that path on Monday.

Nothing interesting on trace or in adb logcat on my Pixel2 XL. Trying to repro on my 5x w/ debug oreo.

Fix here https://chromium-review.googlesource.com/c/chromium/src/+/1155640 but don't love the initial solution. Please advise liberato!

Ensure the codec loop is pumped after EOS while waiting for outputs.

With the async API, MediaCodec will stop sending callbacks once an
EOS buffer has been enqueued. Our MediaCodec based decoders give
up their timer for the async API, so without these notifications
we can end up in a hung state.

This modifies CodecWrapper::output_buffer_release_cb to include the
draining||drained state and then has MediaCodecVideoDecoder make an
informed decision to elide the PumpCodec() if possible.
