Hi all, I am currrently looking into transcoding a media file. My task is to get video in H.264 format, and audio in AAC format. Currently am able to transcode only video into H.264 using the below pipeline gst-launch-0.10 uridecodebin uri=file:///<file location> ! x264enc ! avimux ! filesink location=<file location> I want to transcode audio also in AAC along with the video. I tried with following pipeline but no luck till now. Could someone help me regarding the same. gst-launch avimux name=mux ! filesink location=<file location> sync=true  filesrc location=<I/P location> do-timestamp=true ! qtdemux name=demux demux.video_00 ! 'video/x-264'   ! queue ! mux.video_00  demux.audio_00 ! 'audio/mpeg' ! queue !  faad ! audioconvert ! faac ! queue ! mux.audio_00 Thanks, Jyoti
