int av_buffersrc_buffer | ( | AVFilterContext * | s, |
AVFilterBufferRef * | buf | ||
) |
Add a buffer to the filtergraph s.
buf | buffer containing frame data to be passed down the filtergraph. This function will take ownership of buf, the user must not free it. A NULL buf signals EOF – i.e. no more frames will be sent to this filter. |

int av_buffersrc_write_frame | ( | AVFilterContext * | s, |
const AVFrame * | frame | ||
) |
Add a frame to the buffer source.
s | an instance of the buffersrc filter. |
frame | frame to be added. |
