Unable to identify test #72

Closed FritzHeiden closed 7 months ago

FritzHeiden commented 8 months ago

Running the OF on one of the recordings results in this error:

Exception: Unable to identify the test. Observation will not be made.

I can see from the log that it correctly detects the test from the "Next test about to start" page, then 10 seconds later crashes with the mentioned error. In the recording, checking the frame counts from the logs, I cannot see anything problematic. I use the current config.ini from the repo, just set the test_runner_url.

@FritzHeiden thanks for reporting. Can you share the recording please? Or can you check from frame 36290 to 36300 if there is any pre-test QR code please? And check if it is clear enough to be detected by OF. It seems that OF detected content playing without detecting pre-test QR code. cfhd_12.5_25_50-local/low-latency-short-buffer-playback__t2.html is completed to this is the next test.

FritzHeiden commented 8 months ago

Pre-Test at around 34820: image

Video playback starts until an error occurs during test execution at around 36290 and next test is executed before video is played through: image

Next pre-test shows at around 37200.

yanj-github commented 8 months ago

Thanks @FritzHeiden Can you confirm the following please? I guess test run shows twice of status = finished. OF seems tried to make observation twice for the same test. OF determines end of test by status = finished.

FritzHeiden commented 8 months ago

It first shows status: error, then goes over to status: finished, after which it redirects to the next test.

yanj-github commented 8 months ago

It first shows status: error, then goes over to status: finished, after which it redirects to the next test.

Processed to frame 36290... Is there status = finished here? And more Mezzanine QR code is detected after status = finished? Processed to frame 36310... And more Mezzanine QR code is detected after status = finished? Processed to frame 36320... Is there another status = finished (this is the cause of exception) before the next pre-test QR code at 37200?

If it is easy can you kindly run OF again with --log debug and send me log files in logs folder please?

FritzHeiden commented 8 months ago

The video continues to play for a few seconds with the QR code being updated on time update event, so there are multiple QR code updates containing status: finished, yes.

If it is easy can you kindly run OF again with --log debug and send me log files in logs folder please?

Yes I can do that, will take some time to get there though. I sent you the recording if that helps.

yanj-github commented 8 months ago

@FritzHeiden Thanks, I just got the recording file that I had a look. The cause of the issue is this: image Status = finished but the content is still playing.

OF is unable to determine this is error in the same test or multiple tests, as it detects end of test by Status = finished. Is there alternative way to signal end of current test to OF?

Previously we suggested test runner to add end of test QR code at the end of current test the same way we have pre-test QR code, how difficult is this can be done please?

FritzHeiden commented 8 months ago

An easy and quick fix would be to just stop updating the QR code once status = finished.

As for a solution for this recording, wouldn't it make sense to not abort observation with critical error but instead keep looking for new test (like its done at the very beginning of the recording)?

yanj-github commented 8 months ago

@FritzHeiden yep agree, it would be a quick fix, can be done easy. However there is a risk of some tests in the middle failed quietly without notification when checking the results in test session some test has no OF results. I will print out warning instead on the OF log for such a case.

yanj-github commented 8 months ago

@FritzHeiden this is now done, can you check please?

FritzHeiden commented 7 months ago

Thanks @yanj-github I got past that point in the analysis now, however I get a new error at 126910:

yanj-github commented 7 months ago

@FritzHeiden Is this truncated test? I have looked at the recording the truncated test has main and ad with same content ID A1. OF won't be able to detect the truncating position from mezzanine if they are using same content ID.

FritzHeiden commented 7 months ago

@yanj-github Yes I can see the same from the recording. As other devices played this properly this has to be some issue with the device. Therefore, this should be something the OF should detect as an error. What do you think?

If this happens commonly due to device issues I will unblock the process from OF.

I have another recording where the same error seems to occur:

The analysis now finished for the first video. Thanks. Will try the second now

Second recording ran through without problems aswell. Closing.
