Nicolas George	0bd1be65e8	lavd/xcbgrab: do not try to create refcounted packets. The framework will allocate a buffer and copy the data to it, that takes time. But it avoids constently creating and destroyng the shared memory segment, and that saves more time. On my setup, from ~200 to ~300 FPS at full screen (1920×1200), from ~1400 to ~3300 at smaller size (640×480), similar to legacy x11grab and confirmed by others. Plus, shared memory segments are a scarce resource, allocating potentially many is a bad idea. Note: if the application were to drop all references to the buffer before the next call to av_read_frame(), then passing the shared memory segment as a refcounted buffer would be even more efficient, but it is hard to guarantee, and it does not happen with the ffmpeg command-line tool. Using a small number of preallocated buffers and resorting to a copy when the pool is exhausted would be a solution to get the better of both worlds.	8 years ago

Diego Biurrun	2f806622e1	bktr: Use memset(0) instead of zero initialization for struct sigaction sigaction is not defined in standards as a struct starting with another struct. Some *BSD variants do however, resulting in a warning from the zero initialization, which this change eliminates. This partially reverts `a92be9b856`.	8 years ago
