ReportedBy: pe...@cs... QAContact: gst...@li... GNOME version: Unspecified GNOME milestone: Unspecified Hi, I encountered the following problem while debugging with valgrind a small application. The same shows up when using totem-gstreamer and many ogg files. It seems that theora_read tries to read one byte past de ogg packet (see valgrind output below). My arch is 64bit, os is ubuntu hardy. Stream seems to play allright otherwise. ==21621== Invalid read of size 1 ==21621== at 0xB097B24: oggpackB_read (bitwise.c:360) ==21621== by 0xB8D73B8: theora_read (decode.c:67) ==21621== by 0xB8D5531: th_decode_headerin (decinfo.c:132) ==21621== by 0xB8D4655: theora_decode_header (decapiwrapper.c:147) ==21621== by 0xB6C9C8D: theora_dec_decode_buffer (theoradec.c:890) ==21621== by 0xB6CA7B2: theora_dec_chain (theoradec.c:1437) ==21621== by 0x51357E8: gst_pad_chain_unchecked (gstpad.c:3523) ==21621== by 0xAA68500: gst_ogg_pad_stream_out (gstoggdemux.c:822) ==21621== by 0xAA69870: gst_ogg_pad_submit_page (gstoggdemux.c:1162) ==21621== by 0xAA69E65: gst_ogg_demux_read_chain (gstoggdemux.c:2405) ==21621== by 0xAA6B407: gst_ogg_demux_loop (gstoggdemux.c:2665) ==21621== by 0x514FB28: gst_task_func (gsttask.c:192) ==21621== Address 0xe837b60 is 0 bytes after a block of size 80 alloc'd ==21621== at 0x4C22FAB: malloc (vg_replace_malloc.c:207) ==21621== by 0x4E65EBB: g_malloc (in /usr/lib/libglib-2.0.so.0.1600.4) ==21621== by 0x511386E: gst_buffer_new_and_alloc (gstbuffer.c:328) ==21621== by 0xAA684B2: gst_ogg_pad_stream_out (gstoggdemux.c:816) ==21621== by 0xAA69870: gst_ogg_pad_submit_page (gstoggdemux.c:1162) ==21621== by 0xAA69E65: gst_ogg_demux_read_chain (gstoggdemux.c:2405) ==21621== by 0xAA6B407: gst_ogg_demux_loop (gstoggdemux.c:2665) ==21621== by 0x514FB28: gst_task_func (gsttask.c:192) ==21621== by 0x4E85E86: (within /usr/lib/libglib-2.0.so.0.1600.4) ==21621== by 0x4E84283: (within /usr/lib/libglib-2.0.so.0.1600.4) ==21621== by 0x634F3F6: start_thread (pthread_create.c:297) ==21621== by 0x6A68B2C: clone (in /usr/lib/debug/libc-2.7.so) -- See http://bugzilla.gnome.org/page.cgi?id=email.html for more info about why you received this email, why you can't respond via email, how to stop receiving emails (or reduce the number you receive), and how to contact someone if you are having problems with the system.
