[Linux] Video MimeType Association Oddity

[distantpluto]

Operating system: Linux
Browser version: 31.4.1

I'm having a frustrating time trying to play mpeg video directly in the browser via the VLC Web Plugin. VLC (desktop) reports the file as MPEG-1/2 (mpgv). From what I can gather online the spec is "MPEG-2 transport stream".

The file is being served from the LAN web interface of my Humax PVR (example: http://192.168.66.8:9000/web/media/6206.TS). I've recently started using it again after a few years and it always worked in the past. I made some progress by removing 'mimeTypes.rdf' so it's starting at default and tried adding various mime types to '$HOME/.mime.types' such as

Code: Select all

video/mp2t ts tsv tsa mts m2t m2ts mpgv
video/mpeg mpg mpeg mpe mpgv ts
video/mpgv mpg mpeg mpe mpgv ts

Now the odd thing is, if I enter the saved-to-disk file:/// URL it plays but when served from the Humax it will only download.

When served >> "You have chosen to open..." ... "which is: TS file" ... "What should Pale Moon do with this file?"... I get "Open With >> Browse" and no option for the plugin, even though it's listed as associated in "Preferences >> Applications >> TS file >> Use VLC Web Plugin (in Pale Moon)"

I've fiddled with the mimeTypes.rdf a fair bit but I don't know what I'm doing, so any help would be greatly appreciated!

Is your PVR software sending the correct MIME type header for .TS files?

I did wonder that, how can I check?

Edit: and is there any way to override/force it?

F12 (devtools), Network tab. Make a request for a video, select the network entry and inspect the headers on the right.

That depends on your PVR software? I don't know.

Perhaps this is a valid test page, https://developer.apple.com/streaming/e ... am-ts.html ?

Ok, I've now found time to try this....

Does this mean I need a mimetype entry for 'video/ts'? And if so, what should it be?

Edit: and is there any way to override/force it?

That depends on your PVR software? I don't know.

I meant is there any way for PM to override it, say, with a config setting? Thanks.

Yup. linked to your VLC plugin?
Or for the PVR software to use a MIME type you already know, like video/mp2t

Not without an extension that injects headers.

I've tried various entries for 'video/ts' but I'm getting nowhere. I don't understand, if PM associates .TS files as open with the plugin, why it doesn't?

I'll post back if I get any further. Thanks.

Unfortunately I can't help any further here. I neither use Linux as a driver, and that traffic cone pushware will not be installed on my system.

Just to wind this up...

'video/mp2t' and 'video/ts' are registered with the OS as 'MPEG Transport Stream' and working accordingly.

PM offers "Preferences >> Applications >> TS file >> Use VLC Web Plugin (in Pale Moon)" but the file will only download. A random tested .ts file on the internet plays with the plugin.

I've had a browse through the Humax custom firmware web front end and it suggests the files should be being served as 'video/mp2t' but are actually being received as 'video/ts'. I will try and chase this up on the custom firmware forum.
