Files streamed from yesterday.uktv have weird tags

[MrPeach]

I was able to capture a couple of streams, but they contain unknown tags 40 & 41.
This is what flvmeta finds:

Anyone know how to convert this to something more standard that can be played?
Or is it encrypted somehow? encv & enca == encryption?

What does mediainfo say?
What did you capture with?

[MrPeach]

Mediainfo picks up the data in the two valid tags:

Format : Flash Video
File size : 548 MiB
Duration : 1h 25mn
Overall bit rate : 892 Kbps

Video
Format : AVC
Format/Info : Advanced Video Codec
Format profile : Main@L3.0
Format settings, CABAC : Yes
Format settings, ReFrames : 4 frames
...

Audio
Format : AAC
Format/Info : Advanced Audio Codec
Format profile : LC
Codec ID : 10
Duration : 42mn 57s
...

Captured with rtmpsrv.exe (latest version)

[Baldrick]

And nothing plays it? like VLC media player, SMPLayer.

[MrPeach]

Nope. They all grind through the file and apparently find nothing to play. MPHC, VLC, etc.

Hi ,

Why the durations are different between video and audio ?

Cheers .

[MrPeach]

aazerty,

I'm sorry, I have no idea what you are asking.
Where do you see the lengths are different?

[aazerty]
