I'm trying to downmix from surround into stereo using ffmpeg, and it doesn't seem to be having any effect. Basically, I'm running OBS in surround (4ch) to gain access to higher number channels on my input using the Remuxer plugin, but I'd like the audio in the recorded file to be in stereo so it takes up less space and is more broadly compatible.
I'm writing to an MOV container using the libx264 video encoder, and my audio is at 48k/24bit PCB (pcm_s24be). I added "-ac 2" to the Audio Encoder settings field, but it doesn't seem to be having any effect. I'm pretty new to ffmpeg syntax, so if anyone has any thoughts on how I could actually produce and output file with only two audio channels instead of four, I'd appreciate it! Log attached.
