           Summary: [PATCH] GSM encoding/decoding improvements
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Changes:

1) Modified the encoder and decoder to only accept an 8Khz sample rate.  GSM (by
definition) is limited to a 8Khz sample rate.  The GSM encoder/decoder plugins
were allowing sample rates from 1Khz to 48Khz.  Since GSM files/streams do not
contain any metadata on what rate to decode at you either had to manually
specify the sample rate or you would get odd results.

2) Modified the decoder to produce timestamps/offsets in the buffers that it
generates.

3) Modified encoder/decoder to handle discontinuity & EOS events.
