struct ubuf_mgr * ubuf_sound_bmd_mgr_alloc(uint16_t ubuf_pool_depth, uint32_t SampleType, uint8_t nb_channels, const char *channel) [link]
This function is declared in upipe-blackmagic/ubuf_sound_blackmagic.h source file, line 72.
This function allocates a new instance of the ubuf manager for sound formats using blackmagic.
Parameter list:
- ubuf_pool_depth: maximum number of ubuf structures in the pool
- SampleType: blackmagic sample type
- nb_channels: number of channels
- channel: channel type (see channel reference)
The return value is pointer to manager, or NULL in case of error
