(Core :: Audio/Video: Playback, defect)

Description

[carlosgonzrz]

Attachment: Screenshot_20240325_193229.png

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.6312.52 Safari/537.36

Steps to reproduce:

Open any Webm on any page. Example: https://dl6.webmfiles.org/big-buck-bunny_trailer.webm

On Chromium Chromium 123.0.6312.58 (Official Build) snap (64-bit) the Webm plays with no issues.

Actual results:

Gray box with "No video with supported format and MIME type found". In the console there are 2 warnings with the following message:
"Media resource https://dl6.webmfiles.org/big-buck-bunny_trailer.webm could not be decoded."
"Media resource https://dl6.webmfiles.org/big-buck-bunny_trailer.webm could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_METADATA_ERR (0x806e0006)"

Expected results:

The Webm should have played with no issues. Attached a screenshot of the Webm playing on Chromium 123.0.6312.58 (Official Build) snap (64-bit)

The actual User-Agent is: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:124.0) Gecko/20100101 Firefox/124.0

Comment 2

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Comment 3

[Jim Mathies [:jimm]]

This is playing fine for me on Windows. Internally we're using the ffvpx video decoder. The format is VP8. Your screenshot shows a frame from the video in question, implying it played? Can you provide some more detail here?

Comment 4

[Karl Tomlinson (:karlt)]

The screenshot is from Chromium.

Does a Firefox build downloaded from https://www.mozilla.org/en-US/firefox/download/thanks/ behave similarly?

Comment 5

[Michael J Evans]

I'm getting the same issue with MULTIPLE videos, including https://dl6.webmfiles.org/big-buck-bunny_trailer.webm , using Arch Linux's default Firefox package.

https://support.mozilla.org/en-US/questions/1447784

Did something happen semi-recently that packagers need to change? Maybe built in codecs not enabled by default?

Comment 6

[Michael J Evans]

This Debian bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1068126 is likely also related. It has the same sort of flavor and is also for a 'more recent' Firefox version. I'd been avoiding updates myself due to the KDE update; Arch is now on KDE 6, so I paused updates to wait for a mostly usable desktop.

Comment 7

[Michael J Evans]

After some additional testing on my desktop I think it's related to something in my existing user profiles.

Freshly created clean profile...

WORKS: ESR 115.11.0esr (64-bit) w/HWaccel (both) checked https://dl6.webmfiles.org/big-buck-bunny_trailer.webm

WORKS: ESR 115.11.0esr (64-bit) wo/HWaccel (both) UNchecked (reloaded) https://dl6.webmfiles.org/big-buck-bunny_trailer.webm

Re-test: 126.0 (64-bit) ... Wait, it works in this?

I tried disabling all plugins (except a session manager thing) in one of my less opened profiles; the video didn't work. Though I'm not sure if I have to completely reload that profile for those changes to take effect.

Is there any guide to duplicating a profile, to test out modifying settings/stuff? It might be as simple as close that session then transplant the entire profile content to replace the content of another target other profile folder?

** Though I still need a better set of instructions for collecting data on how Firefox is making decisions, with a focus on troubleshooting media playback at all stages. **

Comment 8

[Karl Tomlinson (:karlt)]

about:logging is the easiest way to collect info on which decisions are made. See https://paul.cx/public/about-logging-presentation.webm and include hidden threads if uploading.

cp -r ~/.mozilla/firefox/XXXXXXXX.default DEST should be good enough to duplicate a profile, and run firefox -no-remote -profile DEST.
Search for "media" "Show only modified preferences" prefs in about:config or perhaps about:support.

Possible root cause/solution: gmp-gmpopenh264
How can gmp-gmpopenh264 be manually-reinstalled / overwriten even if the same version?

media.gmp-gmpopenh264.abi	x86_64-gcc3
media.gmp-gmpopenh264.hashValue	53a58bfb4c8124ad4f7655b99bfdea290033a085e0796b19245b33b91c0948fdac9f0c3e817130b352493a65d9a7a0fc8a7c1eedc618cdaa2b458073

media.gmp-gmpopenh264.lastDownloadFailed	1707213618
media.gmp-gmpopenh264.lastDownloadFailReason	Error: Failed downloading via ServiceRequest, status: 0, channelStatus: 2152398878, errorCode: 2, reason: error
media.gmp-gmpopenh264.lastInstallStart	1707213598
media.gmp-gmpopenh264.lastUpdate	1688546534
media.gmp-gmpopenh264.version	2.3.2

As a final test I tried 'refreshing' Firefox from the about:support tab, THIS IS NOT SOMETHING I WANT TO DO WITH MY PROFILES.

That appears to have forced gmp-gmpopenh264 to reinstall correctly, how can I do this MANUALLY?

That seems to have fixed the video playback issue, but I need a method that is NOT refreshing firefox (and purging all of the profiles and customizations!).

A google result mentioned "Toggle DRM off/on in Options/Preferences to force an update check." - this does NOT WORK.

++
++ Lots of logs etc
++

First I created two profiles, a test template so I can load the profile without restoring 100 tabs, and second an active test profile.

cd ~/.mozilla/firefox/
...
rm -r sm46csvw.ActiveTests/* ; cp -r 7lnvxapn.TestTemplate/* sm46csvw.ActiveTests/ ; DISPLAY=:0 firefox --profile sm46csvw.ActiveTests

firefox --profile sm46csvw.ActiveTests

As a final test I tried 'refreshing' Firefox from the about:support tab, THIS IS NOT SOMETHING I WANT TO DO WITH MY PROFILES.

That appears to have forced gmp-gmpopenh264 to reinstall correctly, how can I do this MANUALLY?

That seems to have fixed the video playback issue, but I need a method that is NOT refreshing firefox (and purging all of the profiles and customizations!).

A google result mentioned "Toggle DRM off/on in Options/Preferences to force an update check." - this does NOT WORK.

How can gmp-gmpopenh264 be manually-reinstalled / overwriten even if the same version?

Attachment: Broken Profile Tests

I've identified the issue: 

INCORRECT SETTING: media.rdd-process.enabled = FALSE

CORRECT SETTING: media.rdd-process.enabled = true // Default

Used the 'reset' option in about config and now retesting https://dl6.webmfiles.org/big-buck-bunny_trailer.webm works.

+ how did I eventually stumble to that solution? +

* about:support -- Revisited again to compare section by section for ANY differences that stood out no matter now small...

* One missing remote process lead me to search 'firefox RDD video' and stumble across
* * https://firefox-source-docs.mozilla.org/dom/ipc/process_model.html#data-decoder-rdd-process
* * A differnt bug #1683808 has a better log flag: https://bugzilla.mozilla.org/show_bug.cgi?id=1683808

Oh that has a MUCH cleaner logging profile to test this issue with:

MOZ_LOG="PlatformDecoderModule:5" firefox --profile 7lnvxapn.TestTemplate

I've identified the issue: 

INCORRECT SETTING: media.rdd-process.enabled = FALSE

CORRECT SETTING: media.rdd-process.enabled = true // Default

Used the 'reset' option in about config and now retesting https://dl6.webmfiles.org/big-buck-bunny_trailer.webm works.

How long should this bug remain open if the original reporter doesn't respond?
I've been able to figure out what the incorrect setting is and how to fix it for my reproduction case.

(my) resolution steps:
about:config
CORRECT THIS SETTING: media.rdd-process.enabled = true // Default

My final troubleshooting steps:

• A broken profile
• A newly created 'clean' test profile
  (which worked, pointing me to a profile specific issue)
• MOZ_LOG="PlatformDecoderModule:5" firefox --profile 7lnvxapn.TestTemplate
  Console output log
• about:support
  Detailed summary including the missing RDD process breadcrumb.

I'm getting this on ffmpeg transcoding streams sent back to the browser -- it works on most mkv files but some mp4 it does not.

import { mp4 } from "@rcompat/http/mime";
import spawn from "@rcompat/stdio/spawn";

const command = "ffmpeg";
const input = "-i pipe:0";
const flags = "-acodec aac -vcodec libx264 -movflags frag_keyframe+empty_moov";
const output = "-f mp4 pipe:1";
const repo = "primatejs/guides";
const url = `https://raw.githubusercontent.com/${repo}/ffmpeg/assets/test.avi`;

export default {
  async get(request) {
    const { stdout, stdin } = spawn(`${command} ${input} ${flags} ${output}`);

    (await fetch(url)).body.pipeTo(stdin);

    return new Response(stdout, { headers: { "content-type": mp4 }});
  }
}

Clear a needinfo that is pending on an inactive user.

Inactive users most likely will not respond; if the missing information is essential and cannot be collected another way, the bug maybe should be closed as INCOMPLETE.

For more information, please visit BugBot documentation.

About this long. :)
