[HELP] APV Codec Support addition?

[GlitterKill]

Is there any way to add a new codec for Hybrid to use without recompiling it?  Basically, can I add support for the Samsung APV codec to an existing Hybrid install?

FFMPEG has recently added native encoder and decoder support for the OpenAPV codec in FFMPEG 8.  It would be great to be able to use it in Hybrid.

No. And recompiling it is the smallest problem. Implementing support for a new format is a lot of work and requires a lot of reading.

It would be great to be able to use it in Hybrid.

'Perceptually lossless video' is usually useless to me, so my personal interest is low.
Haven't seen any real comparison for it.
Haven't looked into compiling it for Linux and MacOS. (the Windows ffmpeg version that comes with Hybrid should already support it)

ffmpeg -h encoder=apv

shows:

https://ffmpeg.org/ffmpeg-codecs.html#liboapv mentions:

oapv-params (parse_apv_params)

Set liboapvenc options using a list of key=value pairs separated by ":". See the liboapv encoder user guide for a list of accepted parameters.

Any idea where to find the 'liboapv encoder user guide for a list of accepted parameter' ?
Any idea what the presets do? If I added support for this format, I would need to know which settings are covered by the presets, so that the UI can reflect this when using a preset.
Any idea how to properly specify HDR signaling?

From the looks of it openapv uses its own container and is video only atm.

Haven't tested it, do you know whether it supports pipe input?
In case it did, it might be better to use this instead of ffmpeg.

What can decode this?

I can do some legwork to find out more information and find answers to your questions.  I know that FFMPEG 8 supports encode and decode.  Android OS 16 has native support, as well as newer samsung devices.  It is primarily meant to be used as an intermediate codec.  I am hoping to replace Cineform HD with it.  OpenAPV is better with multicore systems to improve encoding speed.

Thanks.
Please, also do some testing, but the main issue often finding useful documention.
