WebMar 15, 2024 · If the input frame has a different number of channels, you will need to modify the code accordingly. Also, please note that the returned buffer is allocated dynamically using `malloc ()`, so it is important to free the buffer when you are done using it: ```c int8_t* buffer = avframe_to_int8_array (frame); // use buffer... free (buffer); ``` WebIndexing a tensor in the PyTorch C++ API works very similar to the Python API. All index types such as None / ... / integer / boolean / slice / tensor are available in the C++ API, making translation from Python indexing code to C++ very simple.
