Stream Multicast

[sitro]

Hello,

I should like to view the stream multicast from my provider (IPTV) on a unix box with VLC.
I got some URL but there is a strange behavior in VLC on Linux and the same on Windows
I try to open the stream network like this URL :
udp://@232.0.10.88:8200
I get 4 stream : 3 for audio and 1 for video
But nothing happens

Im message console I have :

Code: Select all

ts info: MPEG-4 descriptor not found for pid 0x12f type 0x11 ts info: MPEG-4 descriptor not found for pid 0x193 type 0x11 ts info: MPEG-4 descriptor not found for pid 0x1f7 type 0x11 ts error: libdvbpsi error (PSI decoder): TS discontinuity (received 12, expected 11) for PID 18 ts error: libdvbpsi error (PSI decoder): TS discontinuity (received 11, expected 10) for PID 0 ts error: libdvbpsi error (PSI decoder): TS discontinuity (received 14, expected 13) for PID 0

I surf in forum , I just find an old answer for the VLC 2.2.0 around this error :

Tools > Preferences > Input/Codecs > Demuxers > MPEG-TS:
- Disable 'Trust in-stream PCR'
- Check Seek based on percent not time
With this both options, m3u8 plays successfully with both sound and video

But in the VLC 2.2.4 I cannot try this workaround because there isn't this option.

Any idea to solve the problem ?

Thanks .

I did a mistake when I wrote : "But in the VLC 2.2.4 I cannot try this workaround because there isn't this option."

In 2.2.4 , this option is in the software but the error is same.

So I tried to install VLC beta nightly build. -> Messages are differents.

Now J get :

Code: Select all

udp error: 1316 bytes packet truncated (MTU was 1316) ... Message repeat

,

Any idea ?
Perhaps playing on the MTU , where is it ?

With ffprobe (ffmpeg) i get this :

Code: Select all

So the very simple question (even if the answer is more complcated) is how I can view the stream in vlc ?

Are you sure the stream URL is correct?

[sitro]

hi,
what do you mean , what could be a correct stream URL ?
In fact to get the URL to put in VLC I look with Wireshark the network and get the stream that was playing on the TV.
Is it possible that the URL need some more stuff . Have you a link where I can learn more on the URL stream. thanks.
