Expand description

Guess the file format.

@param pd data to be probed @param is_opened Whether the file is already opened; determines whether demuxers with or without AVFMT_NOFILE are probed. @param score_max A probe score larger that this is required to accept a detection, the variable is set to the actual detection score afterwards. If the score is <= AVPROBE_SCORE_MAX / 4 it is recommended to retry with a larger probe buffer.
