What is your OS? What is the video type? Can you give us an example so we can replicate?

Same problem.
Tor Browser 13.0.4
Windows 7
“html5: Video file not found” or just does not start.
This problem confirmed in KVC Player, JW Player and Fluid Player. Maybe in some others. Short videos (\<10 minutes) sometimes work. Longer - no.
In Tor Browser 12.5.3 videos playing normally. If you do not open more than 9 browser tabs or do not start a video longer than 2 hours, of course. Otherwise the same error.

let’s try again … what is the video type? Can you give us an example so we can replicate?
what on earth are KVC/JW/Fluid players?
It helps if you can provide STR (steps to reproduce), for example
- tor browser 13.0.4, clean setup
- open the console (ctrl-k)
- go to `https://example.com/videos/cutekittens.html`
- click on the video titled `secondbreakfast`
- expected results: video should play (and kitten gets second breakfast)
- results: video did not play, got console error “TypeError: blah blah”

Did this happen only in TB13 or was it a problem in TB12 as well? You can download an older TB release from [Index of /tor-package-archive/torbrowser/12.5.6](https://archive.torproject.org/tor-package-archive/torbrowser/12.5.6/) - unpack it to e.g. `c:\TB12test`, open it, go to settings and disable updates (so it stays on 12.5.6 for more tests if needed), and get testing
* * *
FWIW, In TB13 we increased `media.memory_cache_max_size` from `16384` to `65536`.
We have `browser.privatebrowsing.forceMediaMemoryCache` = `true` which disables media cache from writing to disk in Private Browsing. MSE (Media Source Extensions) are already stored in-memory in PB. But this shouldn’t be an issue - just noting it, because stranger things have happened

@thorin , @anon53360594
Okay
I spent a few tests.I used random sites and videos to versions 12.5.1 and 13.0.5
Next are examples:
- [https://www.dailymotion.com/video/x8kt7b0](https://www.dailymotion.com/video/x8kt7b0) TB 12.5.1 result: video played. TB 13.0.5 result: video did not play, eternal loading
- [Twitch](https://clips.twitch.tv/embed?clip=StormyHumbleSoybeanMingLee-Ksslq6fRDzWuFJyh&parent=twitch.tv) TB 12.5.1 result: video played. TB 13.0.5 result: video did not play, got console error “This video is either unavailable or not supported in this browser. (Error #4000)”
As for Twitch, streams did not play in both versions, but clips play in version 12.5.1
new users can only put 2 links in a post, delete spaces.
- (NSFW warning) hentaimama. io/episodes/hatsukoi-jikan-episode-1/ TB 12.5.1 result: video played. TB 13.0.5 result: video did not play, got console error “This video file cannot be played.(Error Code: 224003)”
- (NSFW warning) rule34video. com/videos/3152814/bouquetman-compilation/ TB 12.5.1 result: video played. TB 13.0.5 result: video did not play, got console error “html5: Video file not found”
- Youtube and most popular video sites work correctly in both versions.

There are a bunch of different things going on here
- dailymotion + twitch work fine for me on windows (11) in TB13 series
- the other two fail in my TB13 windows same as you
- the hentai one pulls some console clearing etc when you open the console, so hard to see what is going on - works in Firefox (uses JW player)
- the rul34 one throws a MediaError, code 4 - there’s also a Cross-Origin Request Blocked (not sure if related) - works in Firefox
What is your OS? e.g. there are known issues with codecs on linux
edit: [HTML Audio/Video DOM error Property](https://www.w3schools.com/tags/av_prop_error.asp) - code 4 is `MEDIA_ERR_SRC_NOT_SUPPORTED`

I use win 7
Re-installation of video drivers and codecs didn’t help. And I think this is not the problem, since it works in version 12.5.1
Anyway, dailymotion and twitch are not important. 😄 Since you also saw the problem, at least fix hentai and rule34

I also encountered this problem every now and then, on my debian linux.
The cause: Torbrowser depends on a fixed set of libavcodec.so versions.
with my current torbrowser: v53 - v61. my system update installed v62.
The solution: install libavcodec-extra61.
