Defines | |
| #define | AV_OPT_FLAG_ENCODING_PARAM 1 |
| a generic parameter which can be set by the user for muxing or encoding | |
| #define | AV_OPT_FLAG_DECODING_PARAM 2 |
| a generic parameter which can be set by the user for demuxing or decoding | |
| #define | AV_OPT_FLAG_METADATA 4 |
| some data extracted or inserted into the file like title, comment, ... | |
| #define | AV_OPT_FLAG_AUDIO_PARAM 8 |
| #define | AV_OPT_FLAG_VIDEO_PARAM 16 |
| #define | AV_OPT_FLAG_SUBTITLE_PARAM 32 |
| #define | AV_OPT_SEARCH_CHILDREN 0x0001 |
| Search in possible children of the given object first. | |
| #define | AV_OPT_SEARCH_FAKE_OBJ 0x0002 |
| The obj passed to av_opt_find() is fake -- only a double pointer to AVClass instead of a required pointer to a struct containing AVClass. | |
