| ) |
Queue an audio buffer to the audio buffer source.
This is similar to av_asrc_buffer_add_samples(), but the samples are stored in a buffer with known size.
| abuffersrc | audio source buffer context | |
| buf | pointer to the samples data, packed is assumed | |
| size | the size in bytes of the buffer, it must contain an integer number of samples | |
| sample_fmt | sample format of the audio data | |
| ch_layout | channel layout of the audio data | |
| pts | presentation timestamp of the audio buffer | |
| flags | unused |
