Yes, this has two reasons: one is the quality of the detection depends on the model used. I use in the demo a yolov4-tiny that is very fast but not really accurate, leading to many people not being tracked. There can be bugs in the track_sort code as well. The other reason is that the `track_sort` at the moment ignores all the detected boxes which have a position, but no area (they seem to be detected as simple points by `dnn_detect`), which are useless for now, as the SORT implementation at the moment depends only the boxes dimensions for computing IOU (intersection over union). I could think though on extending the code to "fake an area" of a box when it's unknown, which might help to improve the tracking. > > also i think this shows how useful a plugin framework would be for ffmpeg > > with plugins everyone could use,test and contribute to this today. > without plugins, this needs to be merged in ffmpeg git master. (which > will take some time i suspect) Yes, it could even open space for webassembly based plugins, which would be less of a hassle regarding ABI and potentially be cross platform, although I foresee some challenges on getting wasm runtime to share data with the host without copying, especially if the data in the GPU. > > Rust support in FFmpeg is an interresting idea though, iam in favor of > supporting more "safe" languages Great to hear that! > > thx > > [...] > > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe". _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
