C++ (Cpp) avpriv_atomic_ptr_cas Examples

Example #1

File: format.c Project: 26mansi/FFmpeg

void av_register_output_format(AVOutputFormat *format)
{
    AVOutputFormat **p = last_oformat;

    format->next = NULL;
    while(*p || avpriv_atomic_ptr_cas((void * volatile *)p, NULL, format))

Example #2

File: device.c Project: dulton/bvlive

int bv_device_register(BVDevice * dev)
{
	BVDevice **p = last_dev;
	dev->next = NULL;
	while (*p || avpriv_atomic_ptr_cas((void *volatile *) p, NULL, dev))
		p = &(*p)->next;

}

Example #3

File: format.c Project: bas-t/mythtv

void av_register_output_format(AVOutputFormat *format)
{
    AVOutputFormat **p = last_oformat;

    // Note, format could be added after the first 2 checks but that implies that *p is no longer NULL
    while(p != &format->next && !format->next && avpriv_atomic_ptr_cas((void * volatile *)p, NULL, format))
        p = &(*p)->next;

    if (!format->next)

Example #4

int avfilter_register(AVFilter *filter)
{
    AVFilter **f = last_filter;

    /* the filter must select generic or internal exclusively */
    av_assert0((filter->flags & AVFILTER_FLAG_SUPPORT_TIMELINE) != AVFILTER_FLAG_SUPPORT_TIMELINE);

        f = &(*f)->next;
    last_filter = &filter->next;

    return 0;
}

Example #5

File: avfilter.c Project: rosemwahlin/FFmpeg

int avfilter_register(AVFilter *filter)
{
    AVFilter **f = &first_filter;

{
  do {
    bsf->next = first_bitstream_filter;
  } while(bsf->next != avpriv_atomic_ptr_cas((void * volatile *)&first_bitstream_filter, bsf->next, bsf));
