Functions

AVInputFormat * av_iformat_next (const AVInputFormat *f)

If f is NULL, returns the first registered input format, if f is non-NULL, returns the next registered input format after f or NULL if f is the last one.

AVOutputFormat * av_oformat_next (const AVOutputFormat *f)

If f is NULL, returns the first registered output format, if f is non-NULL, returns the next registered output format after f or NULL if f is the last one.

void av_register_input_format (AVInputFormat *format)

void av_register_output_format (AVOutputFormat *format)

int av_match_ext (const char *filename, const char *extensions)

Return a positive value if the given filename has one of the given extensions, 0 otherwise.

AVOutputFormat * av_guess_format (const char *short_name, const char *filename, const char *mime_type)

Return the output format in the list of registered output formats which best matches the provided parameters, or return NULL if there is no match.

enum AVCodecID av_guess_codec (AVOutputFormat *fmt, const char *short_name, const char *filename, const char *mime_type, enum AVMediaType type)

Guess the codec ID based upon muxer and filename.

AVInputFormat * av_find_input_format (const char *short_name)

Find AVInputFormat based on the short name of the input format.

AVInputFormat * av_probe_input_format3 (AVProbeData *pd, int is_opened, int *score_ret)

Guess the file format.

AVInputFormat * av_probe_input_format2 (AVProbeData *pd, int is_opened, int *score_max)

Guess the file format.

AVInputFormat * av_probe_input_format (AVProbeData *pd, int is_opened)

Guess the file format.

int av_probe_input_buffer2 (AVIOContext *pb, AVInputFormat **fmt, const char *filename, void *logctx, unsigned int offset, unsigned int max_probe_size)

Probe a bytestream to determine the input format.

int av_probe_input_buffer (AVIOContext *pb, AVInputFormat **fmt, const char *filename, void *logctx, unsigned int offset, unsigned int max_probe_size)

Like av_probe_input_buffer2() but returns 0 on success.
