Description Riccardo Magliocchetti 2006-06-29 16:57:54 UTC

Moving the progress control back and forth for a minute makes the library segfault.

Steps to reproduce:
1. Open an mpeg file with totem
2. Move back and forth the progress control for a minute or so


Actual results:
totem exits with a "Segmentation fault" message

Expected results:


Does this happen every time?
yes

I'm fairly sure this is fixed in gst-plugins-ugly CVS. Please re-open if not.

        Simplify and don't leak our buffer pool.
        Use _scale_int.
        Remove unfixed bug number from previous ChangeLog entry.

        * ext/mpeg2dec/gstmpeg2dec.h:
        Fix padtemplate as we can now do fractional framerates.
        Small cleanups.
        Use GstSegment.
        Add simple frame dropping QoS.
        Precalc buffer output sizes and UV offsets.
        Always give libmpeg2 a valid fbuf when it wants one.
        don't trust libmpeg to discard our buffers but manage it
        ourselves.
        Fixes #343627, #335288
