Plays in firefox for me using the new 2.5.0 release

[abitrolly]

@joakim-tjernlund thanks or the confirmation. How do you open .ts files in Firefox? For me it only proposes to download them.

[joakim-tjernlund]

ah, stupid me. It was not playing in FF actually. So I built ffmpeg(6.1.1) with openh264 and no x264/x265 and tested with ffplay sc-Intel-C1-L000000.ts That played fine as well.

[abitrolly]

@joakim-tjernlund that's nice to know. Just to confirm, with 2.4.x it doesn't play on your system?

No idea, I moved away from 2.4.1 since long time ago

[abitrolly]

Fair enough.
