How do i get current position of streaming media?

[publicENEMY]

when i receive streaming media from vod videolan, the position slider does not updates itself. is it possible to get current media position from the client? what about using vlc external api?

my server command line is

Code: Select all

vlc.exe -vvv --vlm-conf D:\server.vlm --rtsp-host 127.0.0.1:554

the content of server.vlm is

Code: Select all

new media vod enabled setup media input "D:\Media.mov "

the client command line is

Code: Select all

vlc.exe rtsp://localhost:554/media

media file is a quicktime movie trailer available from apple.com

the session runs fine except the client position slider does not updates itself. but when i change the slider, the streaming starts from the slider position. this does not happen in 0.8.6i.

thanks.

thanks. if the client is 0.8.6i, the position slider is updated. but 0.8.6i have some problem with h.264 streaming.

thanks.

Same happens if you skins interface with 0.9.4?

Same happens if you skins interface with 0.9.4?

Err... Im not using any skins. Just plain qt interface of 0.9.4.

[VLC_help]

I meant if you could test it. If the same issue bothers skins, the problem lies deeper. If it is just QT4 issue, then it is just a QT4 issue

Owh... Okay. Ill try that.

[publicENEMY]

tried with skins in 0.9.4. the position still doesnt update itself.

thanks.

[VLC_help]

Confirmed. trac ticket opened.
http://trac.videolan.org/vlc/ticket/2271

[publicENEMY]

Since i cannot get the position of streaming media, can i get other realted information as well? such as time, number of frames etc?

[publicENEMY]

From the ticket information, courmisch mentioned

AFAIK, the server does not provide the duration infos, and the client cannot update the slider if it does not know the total length. This is not a bug, is it?

and the ticket is closed.

The thing that bothers me is that it used to work. How can it is not a bug? By the way, time info cannot be capture. how about frames info?

Thanks.

[VLC_help]

It is not bug, if there has been documented change to the default behavior. I can create new feature ticket if you want this feature back.

[publicENEMY]

Thank you.

I would like to have the features back. That would help a lot in VOD situation. Please bring it back.

Thank you.

Dear all.
Let me escalate this issue once again, because it's definitely bug.
There are two problems with it:
1. Webplugin: VLC correctly receives media duration data from VOD server and I see correct duration calling vlc.input.length , but all JS calls to retrieve current position (vlc.input.time, vlc.input.position) return 0.
2. VLC player: Position slider does not update it's position, while repositioning perfectly works. VLC does know media duration, because I see it in low right corner in VLC window.

In logs:

live555 debug: setup start: 0.000000 stop:382.000000

382 - it's correct media duration in seconds.

I use VLC 1.1.0 on Win7 and webplugin(both Mozilla and ActiveX).

Please, help. I could provide any info/logs, if somebody need it.

[superware]

Hi kokachev, any luck with the vod position-zero problem?

[Christoph904]

hi,

can you please give me an example how repositioning is working for u
because for me its not working .... posted here: viewtopic.php?f=4&t=84108&start=0#p277877

please let me know, thx
