* lavc/vvc: Fix check whether QG is in first tile colFrank Plowman2024-03-201-1/+1
| | | | | | | | | | | The second part of this condition is intended to check whether the current quantisation group is in the first CTU column of the current tile. The issue is that ctb_to_col_bd gives the x-ordinate of the first column of the current tile *in CTUs*, while xQg gives the x-ordinate of the quantisation group *in samples*. Rectify this by shifting xQg by ctb_log2_size to get xQg in CTUs before comparing. Fixes FFVVC issues #201 and #203.

* ffmpeg: set extra_hw_frames to account for frames held in queuesMark Thompson2024-03-193-1/+40
| | | | | | | | | | Since e0da916b8f5b079a4865eef7f64863f50785463d the ffmpeg utility has held multiple frames output by the decoder in internal queues without telling the decoder that it is going to do so. When the decoder has a fixed-size pool of frames (common in some hardware APIs where the output frames must be stored as an array texture) this could lead to the pool being exhausted and the decoder getting stuck. Fix this by telling the decoder to allocate additional frames according to the queue size.

* avcodec/mpeg12dec: extract only one type of CC substreamMarth642024-03-191-3/+61
| | | | | | | | | | | | | | | | | | | | | In MPEG-2 user data, there can be different types of Closed Captions formats embedded (A53, SCTE-20, or DVD). The current behavior of the CC extraction code in the MPEG-2 decoder is to not be aware of multiple formats if multiple exist, therefore allowing one format to overwrite the other during the extraction process since the CC extraction shares one output buffer for the normalized bytes. This causes sources that have two CC formats to produce flawed output. There exist real-world samples which contain both A53 and SCTE-20 captions in the same MPEG-2 stream, and that manifest this problem. Example of symptom: THANK YOU (expected) --> THTHANANK K YOYOUU (actual) The solution is to pick only the first CC substream observed with valid bytes, and ignore the other types. Additionally, provide an option for users to manually "force" a type in the event that this matters for a particular source. Signed-off-by: Marth64 <marth64@proxyid.net>

* libavfi/dnn: add LibTorch as one of DNN backendWenbin Chen2024-03-197-4/+624
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PyTorch is an open source machine learning framework that accelerates the path from research prototyping to production deployment. Official website: https://pytorch.org/. We call the C++ library of PyTorch as LibTorch, the same below. To build FFmpeg with LibTorch, please take following steps as reference: 1. download LibTorch C++ library in https://pytorch.org/get-started/locally/, please select C++/Java for language, and other options as your need. Please download cxx11 ABI version: (libtorch-cxx11-abi-shared-with-deps-*.zip). 2. unzip the file to your own dir, with command unzip libtorch-shared-with-deps-latest.zip -d your_dir 3. export libtorch_root/libtorch/include and libtorch_root/libtorch/include/torch/csrc/api/include to $PATH export libtorch_root/libtorch/lib/ to $LD_LIBRARY_PATH 4. config FFmpeg with ../configure --enable-libtorch \ --extra-cflag=-I/libtorch_root/libtorch/include \ --extra-cflag=-I/libtorch_root/libtorch/include/torch/csrc/api/include \ --extra-ldflags=-L/libtorch_root/libtorch/lib/ 5. make To run FFmpeg DNN inference with LibTorch backend: ./ffmpeg -i input.jpg -vf \ dnn_processing=dnn_backend=torch:model=LibTorch_model.pt -y output.jpg The LibTorch_model.pt can be generated by Python with torch.jit.script() api. https://pytorch.org/tutorials/advanced/cpp_export.html. This is pytorch official guide about how to convert and load torchscript model. Please note, torch.jit.trace() is not recommanded, since it does not support ambiguous input size.

* avutil/hwcontext_d3d11va: remove check for d3d11 debug layer dllTimo Rothenpieler2024-03-181-7/+3
| | | | | | | | | | At least on latest Win 11 and Visual Studio 2022, that DLL does not exist anymore and can't be installed via any of the usual means. However, debugging works just fine regardless, so this check makes debugging impossible. D3D11CreateDevice will fail anyway if debugging is not supported, so let's rely on that instead.
