Change list-encoders & show_parameters

[Jamaika1]

[farindk]

SVT is no new compression format, it is just a different encoder for AV1. Hence, I do not understand the change.

[Jamaika1]

I believe that show_parameters 'P' should display all functions for all added codecs. I believe that list-encoders function should show all available codecs and their versions. I think adding an encoder function should show specific av1 codec, not all of them. It is a matter of taste. For aom I miss information that codec has turned on. heifenc_avx.exe -P

Encoders (HEIF is default):
Parameters for encoder `x265 HEVC encoder (3.5+41-0b75c44)`:
  quality, default=50, [0;100]
  lossless, default=false
  preset, default=slow, { ultrafast,superfast,veryfast,faster,fast,medium,slow,slower,veryslow,placebo }
  tune, default=ssim, { psnr,ssim,grain,fastdecode }
  tu-intra-depth, default=2, [1;4]
  complexity, [0;100]
  chroma, default=420, { 420,422,444 }
Parameters for encoder `AOMedia Project AV1 Encoder 3.5.0-3981dcb`:
  realtime, default=false
  speed, default=5, [0;9]
  threads, default=4, [1;16]
  quality, default=50, [0;100]
  lossless, default=false
  chroma, default=420, { 420,422,444 }
  tune, default=ssim, { psnr,ssim,butteraugli }
  min-q, default=1, [1;62]

Parameters for encoder `SVT-AV1 encoder 1.2.1-dddda74`:
  speed, default=12, [0;13]
  threads, default=4, [1;16]
  tile-rows, default=4, {1, 2, 4, 8, 16, 32, 64}
  tile-cols, default=4, {1, 2, 4, 8, 16, 32, 64}
  chroma, default=420, { 420,422,444 }
  qp, default=50, [0;63]

heifenc_avx.exe --list-encoders

- x265 = x265 HEVC encoder (3.5+41-0b75c44)
- aom = AOMedia Project AV1 Encoder 3.5.0-3981dcb
- svt = SVT-AV1 encoder 1.2.1-dddda74

Encoders (AVIF is default):
- aom = AOMedia Project AV1 Encoder 3.5.0-3981dcb

not like with heif_compression_AV1 are all codec versions

Encoders (AVIF is default):
- aom = AOMedia Project AV1 Encoder 3.5.0-3981dcb
- svt = SVT-AV1 encoder 1.2.1-dddda74

How about this: --list-encoders only shows the short list with the IDs of the encoders, but if we have both "--list-encoders -P", all encoders are shown with their parameters?

[Jamaika1]

I understand that in your solution I only have: heifenc_avx.exe --list-encoders -P Where are the AOM codecs?

[farindk]

We don't have that yet. It was a proposal to design is such that "--list-encoders -P" would in the future list all encoders and parameters.

[Jamaika1]

Hmm, but you have to guess the --list-encoders -P configuration. I tried to make something simple, but the SVT codec doesn't work with heif_compression_SVT. AOM lossless works for PNG, but lossy does not. It's probably a bug but not in my fix anymore.
