Codecs, codecs, codecs about openrv HOT 10 CLOSED

Never mind. I just stumbled onto ffmpeg.cmake. Congrats on your CMakeLists. They could be much more efficient, but they are really well done.

Well, I reopened this. I am trying to play the Netflix open content movie SolLevante_HDR10_r2020_ST2084_UHD_24fps_1000nit.mov (which is a heavy 4K movie to evaluate performance) and I cannot get the codecs to work. It complains about not knowing codec -147, even thou I recompiled ffmpeg with all bells and whistles. I also have problems with audio codec aac_at.
Is the ffmpeg that OpenRV uses too old for that? Or is it that you guys are protecting the API or are there other legal reasons.

Hi @ggarra13, have you seen this?

Thanks for the hint. But it did not solve my issues. I commented all the codecs and I stiil get:

ERROR: MovieFFMpeg: Unsupported codec_id '147' in /Users/gga/Movies/SolLevante_HDR10_r2020_ST2084_UHD_24fps_1000nit.mov
INFO: /Users/gga/Movies/SolLevante_HDR10_r2020_ST2084_UHD_24fps_1000nit.mov

and:

This is on macOS BTW.

mrViewer 1 and xStudio report the video codec for SolLevante as prores and 4CC as ap4x. Not sure why OpenRV does not know the codec_id.

Hi ggarra13, RV Commercial Apple ProRes support was implemented using a proprietary library provided by Apple. We had to remove it from the Open RV build. This is one of the codec we want to find the proper way to re-enabled. AFAIK, there is Apple ProRes support in ffmpeg but we haven't look at it yet.

Hi @ggarra13, have you seen this?

OpenRV/src/lib/image/mio_ffmpeg/init.cpp

Hi @geffrak I´m not very experienced using github or coding, could you explain to me where should I execute this code?

from openrv.

As @compaga said, you cannot get access to those codecs in OpenRV as commercial RV was using.a proprietary library, and also an old version of FFmpeg.
You don't need to execute any code. You have to wait and see if Autodesk changes to use a more modern library of FFmpeg and adds the code to handle those codecs without a proprietary library. For the time being, OpenRV is crippled in terms of codec support.

Alright, thnx for the reply :)

Given that you have access to the code, you can experiment with stuff like updating FFMPEG (and fixing what might break), changing the compile flags(and mio_ffmpeg's code to allow more) or using native libraries to enable more codecs if you don't want to wait.
