System info

AWS AMi Latest packager version

Issue and steps to reproduce the problem

Audio and Video are out of sync

Packager Command: 5fa3c3ae-63d4-41e6-8065-468c3d0f59c1.txt

/opt/software/packager in=TMP/wm/A/ToS_216p_1M/video.mp4,stream=audio,init_segment=wm/audio/und/mp4a/init.mp4,segmenttemplate=wm/audio/und/mp4a/seg\$Time\$.m4s in=TMP/wm/A/ToS_216p_1M/video.mp4,stream=video,init_segment=tmp/216/A/wm/video/avc1/ToS_216p_1M/seg_init_0.mp4,segment_template=tmp/216/A/wm/video/avc1/ToS_216p1M/seg\$Time\$.m4s in=TMP/wm/B/ToS_216p_1M/video.mp4,stream=video,init_segment=tmp/216/B/wm/video/avc1/ToS_216p_1M/seg_init_0.mp4,segment_template=tmp/216/B/wm/video/avc1/ToS_216p1M/seg\$Time\$.m4s --generate_static_mpd --mpd_output wm/.mpd --enable_widevine_encryption --key_server_url --content_id --signer spedmg --aes_signing_key --generate_dash_if_iop_compliant_mpd=false --aes_signing_iv

What is the expected result? Audio video in sync

What happens instead? We tried on bitmovin player it works fine for few minutes and then starts to go out of sync.

@kaushikkunal99 Can you share the source content and packaged outputs? You can email it to shaka-packager-issues@google.com if it cannot be shared publicly.

kaushikkunal99 commented 6 years ago

@kqyang I have emailed the urls. Can you take a look?

kqyang commented 6 years ago

@kaushikkunal99 Thanks for the streams. I have traced down the bug to the handling of $Time$ in segment template. I am working on the fix.

In the mean time, you can use "$Number$" instead of "$Time$" in segment template. We recommend "$Number$" over "$Time$" as it results in more organized outputs and it is also simpler in player side.

@kaushikkunal99 Can you try the fix I just submitted?

kaushikkunal99 commented 6 years ago

Sure we will try it and let you know. We also found it to be issue with frame rate 23.97. When we fixed 23.97 frame rate the issue went away. We will also try the new packager.

Thanks Kunal

@kaushikkunal99 So looks like there are two separate issues.

Have you had a chance to try out the new packager? Can we close the issue now?

kaushikkunal99 commented 6 years ago

hi @kqyang seems like we are not able to install the latest version of packager on AWS ami. Below is the step its failing. Could you help us with this?

@kaushikkunal99 Have you run "gclient sync" or "gclient runhooks" after syncing to latest release?

kaushikkunal99 commented 6 years ago

@kqyang yes i did. I am trying a fresh install per your documentation.

kaushikkunal99 commented 6 years ago

@kqyang any info on this?

kqyang commented 6 years ago

I am trying a fresh install per your documentation.

Are you seeing the same problem with a fresh install?
