Description

It would be great to change the transcoding encoder settings via the webui.

Currently I am changing them via transcoding.c before compiling to suit my upload bandwidth because the default settings give a bitrate that is too high.

Settings I currently change are:

      octx->i_quant_factor = 0.71;

      // QP curve compression: 0.0 => CBR, 1.0 => CQP.
      // Recommended default: -qcomp 0.60
      octx->qcompress = 0.6;

      // Minimum quantizer. Doesn't need to be changed.
      // Recommended default: -qmin 10
      octx->qmin = *20*;

      // Maximum quantizer. Doesn't need to be changed.
      // Recommended default: -qmax 51
      octx->qmax = *30*;

      av_dict_set(&opts, "preset",  "medium", 0);
      av_dict_set(&opts, "profile", "baseline", 0);

      octx->bit_rate       = *1.5* * octx->width * octx->height;
      octx->rc_buffer_size = 8 * 1024 * 224;
      octx->rc_max_rate    = *1* * octx->rc_buffer_size;
