This is the detailed analysis on the 30s startup delay on Plex.

30s startup delay

Relevant issues:

  • Nvidia 7-2-3 know bug: Not a SHIELD bug: Plex takes 30 seconds to start a video on SMB V3 NAS. Workaround for now is configure NAS to SMB V1. (Root cause is opportunistic locking in the NAS, fix is to turn of opportunistic locking to avoid issues with concurrent users/plex accessing the same files multiple times).
  • Some comments I posted [1].
  • [2], [3].

Fix:

  • Disable SMB opportunistic lock on NAS.

Symptoms:

  • Symptom: when launching media, 30s (32 in fact) of spinning wheel before media shows up. During that time, dashboard doesn't show any connection.
  • Seems to occur only when doing Direct Stream on the Plex App on Shieldh TV Pro.
  • When transcoding (can be forced by disabling HDMI passthrough on Plex App), delay is only 8s on Shield TV Pro.
  • Can't reproduce this anymore. Audio passthrough disabled doesn't trigger transcode when using AC3 anymore (saw a quick update message before playing the media).
  • On Web browser, delay is ~2s, direct or not.
  • On Kodi addon, delay is ~2s.

Summary:

  • The symptoms depend on:
  • Whether media is local or remote (SMB).
Local media means media on Shield TV Pro filesystem when using the Shield Plex serer, and media located on NAS filesystem when using the NAS Plex server.
  • Whether media container is MKV or MP4.
The type of MP4 (standard or web optimize) does not matter here (with respect to delay, direct play decision, or VOBSUB support).
  • Whether using the Plex App or Kodi add-on.
  • Without delay means ~2s.
  • In general remote or local, MP4 or MKV, with or without VOBSUB are always direct played without delay.
  • The exceptions are:
  • On Plex app, Remote MKV are direct play with 30s delay, and MP4 + VOBSUB are transcoded (with bad quality).
Transcode reason is Direct Play was attempted but failed, fallen back to transcoding.
  • On Kodi add-on, Remote MKV are direct play with 20s delay, or sometimes fail to play.
  • In conclusion, if we favor direct play anyway, our best bet is to use the Kodi add-on with the NAS Plex server.
  • But this means overloading the NAS with an additional process.
  • Kodi app is less remote friendly than the Plex app.

Some tests:

  • Select movie.
  • Select version
  • Play from start.
  • When Direct Play, try both Shield as server, and Wolverine.
  • Shield App:

  • SD, 1.4Mbps: Interstellar 480p H265 AC3 5.1 .MKV: '
  • Dec 26, 2020 17:36:35
  • Shield Kodi:
  • Note: on Kodi, even when there is a delay, the play request shows up immediately on the dashboard. Looking in the log, we don't see the same 30s delay between the Content-Length requests.
  • Dec 26, 2020 17:37:51
  • 1080p, 1.9Mbps: Interstellar 1080p H264 AAC stereo .MP4: Direct Play AV, 3s (+SRT subtitles)
  • Note that in the logs, we see transcode messages, even though it direct plays.

  • When using MP4 (web optimized) container, there is no thumbnail when movie is not identified, but there is one when using .MKV container.
  • AC3/AAC loudness difference:
  • With HDMI passthrough, loudness is bigger for AC3 than for AAC. When HDMI passthrough is disabled, AC3 and AAC have same loudness, which is same as AAC with HDMI passthrough.
  • This doesn't occur with Kodi add-on (probably because no HDMI passthrough).

Some script I used to analyze the log: 

#! /bin/bash

transform_time()
{
    # sed -r 's/^(([a-zA-Z]+) ([0-9]+)+, ([0-9]+) ([0-9]+):([0-9]+):([0-9]+)\.[0-9]+)/\4 #\2# \3 \5 \6 \7 \1/;s/#Jan#/01/; s/#Feb#/02/; s/#Mar#/03/; s/#Apr#/04/; s/#May#/05/; s/#Jun#/06/; s/#Jul#/07/; s/#Aug#/08/; s/#Sep#/09/; s/#Oct#/10/; s/#Nov#/11/; s/#Dec#/12/'
    sed -r 's/^(([a-zA-Z]+) ([0-9]+)+, ([0-9]+) ([0-9]+):([0-9]+):([0-9]+)\.[0-9]+)/\4-#\2#-\3-\5-\6-\7 \1/;s/#Jan#/01/; s/#Feb#/02/; s/#Mar#/03/; s/#Apr#/04/; s/#May#/05/; s/#Jun#/06/; s/#Jul#/07/; s/#Aug#/08/; s/#Sep#/09/; s/#Oct#/10/; s/#Nov#/11/; s/#Dec#/12/'
}
