By reading the source code, I found how it is set in libx264 codec, but there is nothing similar at all in nvenc nor in vaapi. In nvenc, I saw stereo fields in the configuration of the encoder but no glue to use them. Although it is probably only a configuration bit or two to add in nvenc case, it seems a bit too complex for me to do it myself. > (2) Is there a way to add the frame-packing information without a full > encoding? On the #x264 IRC channel (freenode) someone answered that there is no such feature in the x264 command line tool (the one created by the same people as the libx264 library if I understand well) Thus, at least for the moment, I will encode with nvenc to check my filters and encode with libx264 for the final render.
