Put your custom image filter code in a class derived from the RecordFilterCopier
class, that you pass to vrs::utils::filterCopy
via a custom MakeStreamFilterFunction
that injects the right filter for each stream (or calls makeCopier
for the streams that shouldn't be modified).
from vrs.
Have you tried class RecordFilterCopier
in https://github.com/facebookresearch/vrs/blob/main/vrs/utils/FilterCopyHelpers.h
? It should allow you to do what you need.

Thank you so much. I have solved my problems. In fact I am working with Meta's Ego4D team and we need this to blur face in VRS file. I provide my implementation here: https://github.com/chenjoya/vrsfacem/blob/master/vrs/vrs/utils/cli/MakeFaceMosaicCopier.cpp
Do you have some guidances?
from vrs.
good to hear you're unblocked.
The code looks good.
Suggestion:
shouldCopyVerbatim()
is a lot more complicated than need be:
makeFaceMosaicCopier
could use RecordFileReader::mightContainImages
and RecordFileReader::mightContainAudio
to either return a FaceMosaic if mightContainImages
is true, otherwise a makeZeroFilterCopier
if mightContainAudio
is true, otherwise, a Copier
. Then you can delete most of the code in shouldCopyVerbatim
and filterAudio
entirely.

Nice. VRS is really talented. I learned a lot.
Thank you so much!

You're welcome!
