Hi all,
I am writing an application where I need to do the following: 1. read a media file from the disk 2. encode this file into a particular format 3. use the rtp payloaders to send the data on to the server To my understanding to use an encode I need to demux and then decode the file data to a raw format and then encode this data using the encoder and then payload the same using rtp payloaders. Now I want to find the encoder dynamically and link with the decoder. Similarly I also need to dynamically link the rtp payloaders. But I am not able to do it. Could anyone help me regarding the same. Thanks, Jyoti ------------------------------------------------------------------------------ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |
Hi, gstreamer-devel:
1. Consider "decodebin" for demux & decode your media file automatically. 2. You mentioned "encode this file into a perticular format", so why you wanna find encoder & rtppayloader dynamically ? You should link your specified encoder to decodebin then link rtppayloader, that's all.

Thanks for the response Eric.
Basically I want my application to act as an RTSP server. So I need to stream the media file contents as rtp packets. For this I encode the given stream into its native format, for eg. if my media file is of type Mpeg4 then I want to encode it into Mpeg4 and then use the compatible RTP payloader element and stream it over the server. The client may be a VLC player which should play media file. So for this I need to dynamically find encoder and rtppayloader to stream media content of file on the server. I need help to dynamically link the compatible encoder and rtppayloader.

Hi, gstreamer-devel:
OK. I think you can read the source code of decodebin for reference. Decodebin add a "typefind" element in it and "typefind" will tell it what the caps of the source media; Then, "find_compatibles" search in the element registry and find out elements which are compatible with this caps; At last, "try_to_link_1" loop through the elements which "find_compatibles" found and try to link it with source. So, I think if you read the source codes of "gst_decode_bin_init", "find_compatibles" and "try_to_link_1", you can figure out the way which makes your work done. You can find these 3 functions in gstdecodebin.c.
