Hi, I am actually reading a mp4 file and decoding it and writing the decoded buffer to a file as below: gst-launch filesrc location=test.mp4 ! qtdemux name=d d.audio_00 ! avdec_aac ! appsink d.video_00 ! avdec_h264 ! appsink Now i write these audio video buffers to a files audio.pcm and video.yuv using fwrite. In my other application i use audio.pcm and video.yuv to play them as below using appsrc appsrc ! audioparse ! alsasink appsrc ! videoparse ! xvimagesink and will set the properties for audio and videoparse. i am able to see video but no audio. below are the property values which were working in gstreamer0.1 endiannes=1234 width=16 depth=16 i had not set format property previously.

If you tell us the previous settings for format, endianness, width, depth and signedness we can tell you the format..
