Subject: Re: [FFmpeg-devel] [PATCH] fate/filter-video.mak: do not use bit-exact
check for dnn_processing

Am Fr., 17. Jan. 2020 um 15:37 Uhr schrieb Guo, Yejun <yejun....@intel.com>:

the reason is that the tested models are in float format

The two reference files are ~1MB together: Do we want / need that?
(No opinion here.)

how about just keeping one test (for format rgb24) for vf_dnn_processing? The 
rgb format might be the most popular format for vf_dnn_processing.

And the test has two materials:
1)  fate-suite/dnn_processing/dnn_rgb_processing.model (can be renamed from 
halve_first_channel_float.model, 184 byte now)
2)  fate-suite/filter-reference/dnn_rgb_processing.raw (can be renamed from 
dnn_processing-halve_first_channel_float.raw, 446KB now)

When we support more models (the most effort is to add more dnn layers in 
native mode),
I can update both dnn_rgb_processing.model (the file size will be increased bit 
by bit) and dnn_rgb_processing.raw (the file size will not change much).

Keep in mind that ideally, you shouldn't be changing the reference files in the separate samples directory incrementially; ideally they should be fairly static.

Reducing the number of tests, if you need large test references, sounds sensible to me.
