decode one rtjpeg YUV420 frame
- Parameters
-
c | context, must be initialized via ff_rtjpeg_decode_init |
f | AVFrame to place decoded frame into. If parts of the frame are not coded they are left unchanged, so consider initializing it |
buf | buffer containing input data |
buf_size | length of input data in bytes |
- Returns
- number of bytes consumed from the input buffer
