As discussed recently, the vf_sr filter and the DNN framework have an issue: unreproducable weights and questionable license, as well as overall unfitting coding style to the rest of the project.
The vf_sr filter in particular has weights embedded which weight the libavfilter binary by a bit and cannot currently be reproduced. There's an overall consensus that NN filters should accept external weights only, as the nnedi filter currently does. So, temporarily remove both until the coding style issues have been fixed with the framework and the filter has been modified to accept external weights. Also, there's a discussion by the Debian folks as to whether to treat pretrained NNs as non-free[0], hence its not just our project that's affected by the questionable license of distributing pretrained NN weights. Due to the weight of the patch (more than 1mb!) I've uploaded it to https://0x0.st/sVEH.patch if anyone wants to test it. The change stat is printed below.
