| int ff_mlp_read_major_sync | ( | void * | log, | |
| MLPHeaderInfo * | mh, | |||
| GetBitContext * | gb | |||
| ) |
Read a major sync info header - contains high level information about the stream - sample rate, channel arrangement etc.
Most of this information is not actually necessary for decoding, only for playback. gb must be a freshly initialized GetBitContext with no bits read.
