#9285: Excessive GPU memory usage with nvdec hwaccel -------------------------------------+------------------------------------- Reporter: Ridley | Type: defect Combs | Status: new | Priority: normal Component: avcodec | Version: Keywords: nvdec | unspecified nvidia | Blocked By: Blocking: | Reproduced by developer: 1 Analyzed by developer: 1 | -------------------------------------+------------------------------------- When decoding video using the CUDA hwaccel, `ff_nvdec_decode_init()` sets both `ulNumDecodeSurfaces` and `ulNumOutputSurfaces` to `frames_ctx->initial_pool_size`, which in turn is set by `ff_nvdec_decode_init` to `dpb_size + 2`, which in turn has 3 added by `ff_decode_get_hw_frames_ctx()` and `extra_hw_frames` + `thread_count` added by `avcodec_get_hw_frames_parameters`. This is excessive. Only `ulNumDecodeSurfaces` needs additional frames based on thread count (the output surfaces are only used in `nvdec_retrieve_data`, which runs on the consumer's single thread), while only `ulNumOutputSurfaces` needs the 3 additional output frames from `ff_decode_get_hw_frames_ctx()` or the ones from `extra_hw_frames` (the decode surfaces are never exposed to the consumer). I'm not sure what the best way to handle this is. Maybe nvdec should ignore what the generic code sets `initial_pool_size` to altogether and instead calculate its buffer counts internally, duplicating the generic code's behavior only where appropriate? The `initial_pool_size` value seems to be designed for systems where the decoder's internal buffered frames are returned directly to the user, but that's not the case here. Additionally, it doesn't seem like multithreading in CUDA actually serves any purpose; I see no performance gain when using multiple threads vs 1. Is it useful with any hardware decoder? Should we be defaulting multithreading off when using a hwaccel, or forcing it off unless the hwaccel fails and software fallback occurs? This can result in some pretty hefty memory usage for no reason by default on many-core machines. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9285> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
