>From what i understand, aom-params can only be used to set key-value pairs that are set using the aom_codec_set_option() function call.

There is no way to do that in a generic way other than to introduce a specific option like this. -- Vignesh _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
