Hello everyone,
I want to know if it is possible to play video data in buffer? I can achieve it only putting the whole video file in buffer but can not put only a fraction of it.
Does anyone know why?
Or can you give me some advice on playing video data in buffer?
Thank you in advance and I really appreciate you help.

Hi,

As per my knowledge , there is no implementation in the lib for OpenDesL() method.So, we cant use that method.

If u know any 3gp/Mpeg file format then you can do like this,

Create a buffer and store the rec.data on it.
Once its reached certain amount of the video data, just store that data into a file with ext of .3gp/.Mpeg.
And give this file to the OpenFileL(). It ll play.
First you need knowledge of any of video file formats which plays on the device.

Cheers,

Dear Karthikeyan.B,
Thank you for your reply, and I have tried the method but it didn't work, and I think it is not just divide one big video file into some small ones and make sure every small ones play successfully. I mean that it must be related to the specific codec.
These days I have been looking for the codecs of some popular video formats and I found some open source codes for AVI but it's too complicated and I think it's a large project to port it into Symbian OS.
Still, thank you for your good suggestions.

Best wishes!

Hi Lionycq,

You can achieve what i told you previously.
Because, i tried it simply, just get some amount of video data(3gp) and save it into file with ext of .3gp.
And append the end of file character as 0000. Then we can play this file simply.

Now i m also searching for the open source video codecs. I found the OGG audio codec.
Do you have any video codecs then let me know or send me the link.

Thanks in Advance...
