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