Re: 3gp parser

Hi,

 

How you have able to see the header for the .3GP file?

 

I want to access the .3GP file contents?

Re: 3gp parser

it is not a really 3gp file. It is translated to 3gp format at the end of the video. You must to do a reverse engine to understand the parser for this file format. Naturally only if you need to access in real time live.

 

I did and work.

Re: 3gp parser

Hi, Can you provide code sample if possible?

Can we really get the live stream?

Re: 3gp parser

You won't be able to get the live stream but you can parse the 3gp file if it's on the file system. Since I have no Blackberry at hands I don't really know how the 3gp looks like - it's pretty generic. If you send me a file I could easily provide an example how to extract the raw data from the 3gp. Perhaps that helps you to analyze the live stream since I suspect the temporary file to contain simply that data.

Re: 3gp parser

@stefano: Am I asking too much if I ask you to give some more details about the parser you built?

 

Or if someone else has a solution, please be more specific. 

 

thanks

Re: 3gp parser

The solution is make a reverse engine of that raw file to understand where are the frames audio and video. I developed that lib and work, it is not free. If somebody is interested please send a private message.
