           Summary: dv1394src clock continues to be broken
    Classification: Desktop
           Product: GStreamer
           Version: git

            Status: UNCONFIRMED

the dv1394 src was broken last september by:

commit 3dc2c2472c0b70a05b09c2248e9c332fdb08b98d

    dv1394src: Add a clock based on isochronous cycle counter

This caused the clock (as reported by progressreport) to zoom forward and
backward and generally rendered dv1394src unusable.  Since then there's been a
new patch that fixed the 'back and forth' problem:

commit 63624f966e4f24145bc6c1b1e6a441c119eb6976

    dv1394src: Fix internal clock

    Fixes #593910.

...but the clock is still not usable.

As of current head, the dv1394src will run, but output occurs with bursts of
frames having approximately the same timestamp, so video consists of bursts of
5-15 frames, then no frames for an extended period, then another burst of
frames, etc.
