Hi, I got a problem when playing speex audio using gstreamer. This happens with some files only. First, I have a video file, using gstreamer to encode audio data in speex format then playback and got this problem: Unexpected discontinuity in audio timestamps of more than half a second (0:00:00.504375000), resyncing - If I play it again, the problem happens again with same timestamps. - If I use lame to encode, everything is ok - With same speex data, but now I use mplayer to play, everything is ok too. - I use google and found that there was a bug like this not only for speex data but haven't found any clue to say that the bug was fixed. So, is there any thing I need to notice when convert audio data into speex format ? like some parameter for speexenc. P/S here's the pipeline I used to get a file with speex audio data: gst-launch filesrc location=kavatina_gstar.wmv ! asfdemux ! decodebin ! audioconvert ! speexenc ! oggmux ! filesink location=kavatina_speex.ogg Thanks in advance !
