FFMPEG --recordconfig options

[selsine]

Hi Everyone,

I've been working on streaming to Twitch using RetroPie and I'm wondering if anyone has a list of the available options that you can set in the --recordconfig file and whether or not you can pass arbitrary commandline options?

The most details I can find in the RetroArch Wiki are the following:

vcodec = <codec> # Same as -vcodec
acodec = <codec> # Same as -acodec
format = <format> # Muxer format to use. E.g. mkv, flv or mp4. This is normally inferred, but must be set when using extensionless formats like RTMP (streaming).
threads = <threads> # Threads to use when encoding video. Should be set to (# of CPU threads - 1).
frame_drop_ratio = <ratio> # Only encodes every <ratio> frames.
pix_fmt = <pix_fmt> # Same as -pix_fmt, no default is assumed, must be set!
scale_factor = <factor> # Scales input by <factor>. Useful when encoding in chroma subsampled formats like yuv420p.
sample_rate = <rate> # Audio output sampling rate.
audio_global_quality = <qual> # Global quality for audio (VBR). Maps to codec->global_quality in API. Play around with it. Higher = better. 75 seems to be a fair value.
audio_bit_rate = <bitrate> # Audio bit rate (CBR). This is in bit/s, so use e.g. 192000 for 192 kb/s.

video_{option} = <value> # Sets generic video option {option} to <value>. This is codec specific. Mostly useful for libx264.
audio_{option} = <value> # Sets generic audio option {option} to <value>. This is codec specific.

What I'm curious about is whether it is possible to pass additional commanline options to ffmpeg via the --recordconfig file? E.g. how would I pass the -ac 2 option to ffmpeg?

Sorry to bump this, but does anyone know how to pass additional commandline options to ffmpeg via --recordconfig?
