* avcodec/mediacodec: add av_mediacodec_render_buffer_at_time()Aman Gupta2018-10-11
| | | | | | | | | | The existing av_mediacodec_release_buffer allows the user to render or discard the Surface-backed frame. This new method allows the user to control exactly when the frame will be rendered to its SurfaceView. Available since Android API 21. Signed-off-by: Aman Gupta <aman@tmm1.net>

* h264_slice: Copy the value of x264_build before calling ↵Derek Buitenhuis2018-10-09
| | | | | | | | | | | | | h264_slice_header_init during thread init If we don't copy this value first, it is seen as 0 by h264_slice_header_init, due to zero-allocation of the new context, triggering an old hack that multiplied the denominator by 2 for files produced by old x264 versions, but only if more than one thread was used.
