<p>Cspan64: </p> <hr /> <div>== Outstanding issues ==<br /> <br /> I think, I've found a fix for the second issue (halt after 45 minutes) in theora_str:<br /> Replace this function in main.c:<br /> <br /> &lt;pre&gt;<br /> inline Timestamp_t GetTimestamp(void)<br /> {<br /> struct timeval tv;<br /> gettimeofday(&amp;tv, NULL);<br /> // return (Timestamp_t) ((tv.tv_sec * TimestampTicks) + tv.tv_usec); // old<br /> return (( (Timestamp_t) tv.tv_sec * TimestampTicks) + tv.tv_usec); // fixing the 45-min overflow<br /> // (blow up 32 to 64 bits _before_ doing the calculations which otherwise give an overflow)<br /> // See glib/gtimer.h how the they handle timevals without any multiply,<br /> // but the small amount of time saved might not be of any concern here.<br /> }<br /> &lt;/pre&gt;<br /> <br /> I just _think_ this is the bug, because I don't have a camera yet to test it.<br /> Hopefully we can order one soon.<br /> I'm really confident, that is is the right fix, because the error is obvious.<br /> The bug was a strong argument against your cameras, so I looked for it.<br /> <br /> I post this here because I found no other place to do so and couldn't even find the theora_str files in the heck of the CVS tree.<br /> <br /> Greetings --[[User:Cspan64|Cspan64]] 14:02, 29 September 2007 (CDT)</div>
