int64_t av_gettime_relative(void)
Get the current time in microseconds since some unspecified starting point.
int main(int argc, char **argv)
filter_frame For filters that do not use the this method is called when a frame is pushed to the filter s input It can be called at any time except in a reentrant way If the input frame is enough to produce output
#define AVSEEK_SIZE
ORing this as the "whence" parameter to a seek function causes it to return the filesize without seek...
int64_t avio_size(AVIOContext *s)
Get the filesize.
int av_strerror(int errnum, char *errbuf, size_t errbuf_size)
Put a description of the AVERROR code errnum in errbuf.
int avformat_network_init(void)
Do global initialization of network libraries.
#define AVIO_FLAG_WRITE
write-only
int av_usleep(unsigned usec)
Sleep for a period of time.
void avio_flush(AVIOContext *s)
Force flushing of buffered data.
static int usage(const char *argv0, int ret)
static int64_t start_time
void avio_write(AVIOContext *s, const unsigned char *buf, int size)
void av_dict_free(AVDictionary **pm)
Free all the memory allocated for an AVDictionary struct and all keys and values.
and forward the test the status of outputs and forward it to the corresponding return FFERROR_NOT_READY If the filters stores internally one or a few frame for some input
#define i(width, name, range_min, range_max)
#define AV_TIME_BASE
Internal time base represented as integer.
int64_t avio_seek(AVIOContext *s, int64_t offset, int whence)
fseek() equivalent for AVIOContext.
int avformat_network_deinit(void)
Undo the initialization done by avformat_network_init.
int av_dict_parse_string(AVDictionary **pm, const char *str, const char *key_val_sep, const char *pairs_sep, int flags)
Parse the key/value pairs list and add the parsed entries to a dictionary.
int avio_read(AVIOContext *s, unsigned char *buf, int size)
Read size bytes from AVIOContext into buf.
#define AVIO_FLAG_READ
read-only
int avio_open2(AVIOContext **s, const char *filename, int flags, const AVIOInterruptCB *int_cb, AVDictionary **options)
Create and initialize a AVIOContext for accessing the resource indicated by url.
int avio_close(AVIOContext *s)
Close the resource accessed by the AVIOContext s and free it.
