Use -b:a 128k for the bitrate and -ar 44100 for the sample rate. A 24/7 schedule does not call for a different audio bitrate; reliability also depends on a stable source, sufficient bandwidth, and stream monitoring.
Recommended FFmpeg audio settings for stereo
YouTube’s live encoder guidance recommends AAC at 128 kbps for stereo audio and a 44.1 kHz sample rate. The devotional content does not change those technical recommendations: choose settings for the actual channel layout, not the program’s subject.
If the input video is compatible with stream copy, this example passes video through unchanged and encodes audio to AAC:
ffmpeg -re -i input.mp4
-c:v copy
-c:a aac -b:a 128k -ar 44100
-f flv 'rtmps://YOUR_YOUTUBE_INGEST_ADDRESS/YOUR_STREAM_KEY'Replace input.mp4 with your media file and the destination with the ingest URL and stream key shown in YouTube Live Control Room. Keep the stream key private. YouTube recommends RTMPS, the secure extension to RTMP; confirm the current ingest details in your channel before starting a production stream.

- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
What each audio option does
-c:a aacselects FFmpeg’s native AAC audio encoder.-b:a 128ksets the audio bitrate to 128 kilobits per second. FFmpeg documents bitrate in bits per second; specifying this option for its native AAC encoder activates constant-bitrate mode.-ar 44100sets the audio sample rate to 44,100 Hz.
Output options apply to the output that follows them, so keep these audio options after the input and before the output URL. FFmpeg’s native AAC encoder defaults to 128 kbps if no bitrate is specified, but writing -b:a 128k explicitly makes the intended setting easier to inspect. FFmpeg documentation: AAC encoder
When -c:v copy is appropriate
-c:v copy avoids re-encoding video, but it is not universally suitable. Use it only if the input video codec and container path are compatible with the chosen output. If they are not, configure a video encoder and its settings separately. A still-image stream or a different input type may also require different video options; the audio settings above do not determine those choices.

Use a different bitrate only for a different channel layout
| Program audio layout | YouTube live recommendation | Important qualification |
|---|---|---|
| Stereo | AAC, 128 kbps, 44.1 kHz | Standard choice for a two-channel program. |
| 5.1 surround | AAC, 384 kbps, 48 kHz | Use only for an actual 5.1 mix. YouTube’s guidance says 5.1 over RTMP/RTMPS is supported only with AAC. |
| Mono or another layout | No separate recommendation stated | Do not assume the stereo recommendation is automatically the right configuration; verify the intended channel layout and inspect the encoded output. |
These are YouTube live ingest recommendations, not upload settings. Check YouTube’s current live guidance and the settings in Live Control Room before making a production change. YouTube live encoder settings
Check the stream for continuous operation
Audio bitrate alone cannot keep a stream online. YouTube advises allowing bandwidth headroom for the total stream bitrate; its streaming tips recommend 20% room. Treat that as a recommendation, not a guarantee against outages. Test a representative stream, watch stream health in Live Control Room, and check that audio remains present and correctly routed when sources change. YouTube: Streaming tips

A bitrate setting cannot prevent an input file from ending, a source from failing, or a network connection from dropping. FFmpeg’s configuration does not prescribe one universal process supervisor, restart policy, or backup input; those depend on your host and operating requirements. Plan and test those separately for an unattended 24/7 stream.
Quick preflight checklist
- Confirm the source is intended to be stereo before using the stereo settings.
- Confirm the input can be stream-copied if you use
-c:v copy. - Check that the destination URL and stream key match the current YouTube Live Control Room details.
- Allow bandwidth headroom for the total stream bitrate and monitor Live Control Room stream health during a representative test.
- Verify audio routing and continuity, especially across source changes.
Troubleshooting common audio-setting problems
The stream has no audio
Check that the input contains an audio stream and that FFmpeg is mapping and encoding it. Confirm that the selected input and output options are in the right order, then verify audio in the live preview and stream health indicators.

The audio layout or channel count is wrong
Inspect the source and encoded output rather than assuming it is stereo. If the program is 5.1, use the 5.1-specific YouTube recommendation only when the mix and channel layout are genuinely 5.1. For mono or another layout, YouTube’s cited live settings guidance gives no separate bitrate recommendation.
The output cannot use video stream copy
If the video codec or container path is incompatible with the output, -c:v copy will not be suitable. Configure video encoding for the source and destination instead; changing -b:a does not solve a video compatibility issue.

The stream drops or reports poor health
Do not treat audio bitrate as a fix for a source or network interruption. Check total stream bandwidth, leave the recommended headroom, inspect YouTube’s stream health, and investigate the host, network, and input. Test any restart or backup-source strategy before relying on it unattended.
A different AAC encoder behaves differently
This example uses FFmpeg’s native aac encoder and does not assume an optional encoder such as libfdk_aac is installed. Encoder behavior and options vary by implementation; check your installed FFmpeg build and the documentation for the encoder you choose. FFmpeg AAC encoder documentation
