* Remove unnecessary parameter from ff_thread_init() and fix behaviorAlexander Strange2011-04-051-1/+1
| | | | | | | | | | | thread_count passed to ff_thread_init() is only used to set AVCodecContext. thread_count, and can be removed. Instead move it to the legacy implementation of avcodec_thread_init(). This also fixes the problem that calling avcodec_thread_init() with pthreads enabled did not set it since ff1efc524cb3c60f2f746e3b4550bb1a86c65316.

* threads: allow thread count of zeroMans Rullgard2011-03-021-2/+5
| | | | | | | | | This moves setting the thread count to a minimum of 1 to frame_thread_init(), allowing a value of zero to propagate through to the codec if frame threading is not used. This makes auto-threads work in libx264. Signed-off-by: Mans Rullgard <mans@mansr.com>
* pthreads: Fix bug introduced with thread_safe_callbacksAlexander Strange2011-03-011-2/+7
| | | | | | | | | For intra codecs, ff_thread_finish_setup() is called before decoding starts automatically. However, get_buffer can only be used before it's called, so adding this requirement broke frame threading for them. Fixed by moving the call until after get_buffer is finished.

* Deprecate avcodec_thread_init()Alexander Strange2011-02-091-3/+3
| | | | | | | | | | | | | | As a side effect of the last commit, avcodec_open() now calls it automatically, so there is no longer any need for clients to call it. Instead they should set AVCodecContext.thread_count. avcodec_thread_free() is deprecated, and will be removed from avcodec.h at the next MAJOR libavcodec bump. Rename the functions to ff_thread_init/free, since they are now internal. Wrappers are provided to maintain API compatibility. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* Always call avcodec_thread_init()Måns Rullgård2010-01-201-1/+5
| | | | | | | | | The various avcodec_thread_init() functions are updated to return immediately after setting avctx->thread_count. This allows -threads 0 to pass through to codecs. It also simplifies the usage for apps using libavcodec. Originally committed as revision 21358 to svn://svn.ffmpeg.org/ffmpeg/trunk
