Hi all,              I am writing a application for DVD playback using the rsndvdbin. I edited the resindvdbin.c code so that it can handle  different audio format. i am not using the decodebin. I tried playing the DVD's having different audio format and it worked fine. But when i tried playing a DVD in which one list of Video songs had a audio format( audio/x-private1-ac3) and the other List of songs were in "audio/mpeg" format, the 'dvddemux' dose not generate the pad-added signal correctly.          The 'dvddemux'  generate the pad-added signal only once for different audio format. i.e:- If its playing a video with audio format of "audio/x-private1-ac3" and now if i select to play a video with audio format "audio/mpeg"  dvddemux generate the 'pad-added' signal. But now if i want to play a video which has a audio format of  "audio/x-private1-ac3" the dvddemux dose not generate the pad-added signal. Because of which i am not able to play the audio, but the video is been played. But if i try playing the video with "audio/mpeg" audio format it works fine, since the pad is allreay linked.          Do i have to make any changes in the "gstmpegdemux.c" and "resindvdsrc.c" ?? Thanks all.
