Description Zaheer Abbas Merali 2006-09-27 14:50:21 UTC

It will segfault trying to allocate too much memory if the segment start is too much > 0 as it will try and allocate buffer for silence that is too large.

Comment 1 Wim Taymans 2006-09-28 10:50:39 UTC

        * gst/audiorate/gstaudiorate.c: (gst_audio_rate_reset),
        (gst_audio_rate_sink_event), (gst_audio_rate_convert),
        (gst_audio_rate_convert_segments), (gst_audio_rate_chain):
        Keep sink and src segment to keep track of time and support more
        input formats.
        Fix bogus next_offset and run_time calculation, don't understand how
        this could have worked before. Fixes #357976.
        Remove some unneeded vars.

Comment 3 Edward Hervey 2006-09-29 07:58:54 UTC

zaheer, this seems to be a bug in fluts requesting too much in buffer_alloc, not an audiorate bug AFAIK.

Comment 4 Tim-Philipp Müller 2006-10-17 20:11:25 UTC

What's the status on this? Has this been fixed in flutsdemux? Should it be moved over to fluendo's trac?
