QCELP (Qualcomm Code Excited Linear Prediction), also known as Qualcomm PureVoice, is a speech codec developed in 1994 to increase the speech quality of the IS-96A codec used earlier in CDMA networks. It was replaced later with EVRC since it provides better speech quality with fewer bits. There are two versions available: QCELP8 and QCELP13 and they use 8 and 13 Kbit/s respectively. This audio codec is not recognized by gstreamer, but is well recognized by ffmpeg (used by mplayer and vlc). There is no codec pack or application that is able to view these files. Example Content: http://cyberchinese-online.com/media/video/pcr/L_1.mov Current Result: Plays video but audio is muted Expected result: Plays both audio and video in sync, with no delay. Current workarround: 1) Select the totem-mozilla package for installation 2) Select to uninstall mozilla-mplayer -OR- If you have the actual file, open it in mplayer. This bug is a request to include the QCLP audio codec to a gstreamer plugin pack. If there are any issues (legal or otherwise parties) with doing this please comment on this bug.
