Hi all, I am trying to play *minnale.mp4 *whose *mp4info* is as shown below. *# mp4info minnale.mp4* Track Type Info 1 video MPEG-4 Simple @ L1, 97.833 secs, 136 kbps, 176x144 @ 12.000041 fps 2 audio MPEG-4 AAC LC, 97.568 secs, 64 kbps, 32000 Hz 3 hint Payload MP4V-ES for track 1 4 hint Payload mpeg4-generic for track 2 My SIP client *Ekiga 4.0.0* which has *MP4V-ES* video codec support. I have enabled *MP4V-ES* video codec in Freeswitch, but there is no * mpeg4-generic* audio codec in both Ekiga client and Freeswitch server. I am streaming *minnale.mp4* from freeswitch server to *Ekiga* client. Now on my client side I could see only the video, but there is distortion in audio. How can I overcome above issue? Is there any alternate way to play *.mp4* files?. Please let me know. Thanks & Regards, Muqtheear.S
