To stream a prerecorded video to YouTube Live from AWS Mumbai, run an encoder on an EC2 instance in the Asia Pacific (Mumbai) region (ap-south-1), then send the video to the stream URL and stream key from YouTube Studio’s Live Control Room. Configure outbound internet access, use RTMPS when supported, and confirm the preview and stream health before going live.
Before you begin
- A YouTube channel eligible for live streaming. YouTube says the channel must be verified and must not have live-streaming restrictions in the preceding 90 days. See YouTube’s live-streaming eligibility guidance.
- An AWS account with permission to create and configure an EC2 instance and its network.
- A prerecorded video and an encoder installed on the EC2 host. FFmpeg is one possible encoder, but the exact command depends on the input file and desired output; the sources cited here do not validate a specific command.
- A YouTube stream URL and stream key, copied from Live Control Room. Treat the key as a credential: anyone who obtains it may be able to send video to your stream.
1. Create or schedule the YouTube stream
- Open YouTube Studio and go to Live Control Room.
- Create a stream or select a scheduled stream. Copy the server/stream URL and stream key shown for the encoder.
- Keep the stream key private. If it is exposed, reset it in Live Control Room before using the stream again. YouTube explains that stream keys are like a stream’s password and address in Manage live stream settings.
For a scheduled stream, the encoder feed can be started before the event; check that the preview appears in Live Control Room, then select Go live when ready. YouTube’s encoder workflow is described in Create a YouTube live stream with an encoder.
2. Launch an EC2 host in AWS Mumbai
Choose the AWS region named Asia Pacific (Mumbai), region code ap-south-1. AWS lists regional EC2 service endpoints at Amazon EC2 service endpoints.
Choose compute for the actual encoding task
Instance size depends on whether the encoder can stream-copy or remux the existing media, or must transcode it. Transcoding generally requires more compute, with the workload also affected by resolution, frame rate, codec, software versus hardware encoding, and reliability needs. The cited AWS and YouTube documentation does not establish a suitable instance size or benchmark for a particular file. Test the intended workload and monitor CPU, memory, and outbound stability rather than assuming a specific EC2 type will suffice.

Support for VISCA over IP encoder workflows enables flexible PTZ control, while the dashboard provides video preview and system status.
Choose an outbound network path
The encoder sends media out to YouTube, so the EC2 instance needs DNS resolution and outbound connectivity to the chosen ingest endpoint. AWS documents two common network patterns:
- Public subnet: route the subnet through an internet gateway and give the instance public addressing. AWS outlines the setup in Add internet access to a subnet.
- Private subnet: use a NAT device for outbound internet access without assigning the instance a public address.
Check the subnet route, security group, network ACL, DNS, and any egress restrictions. The stream is outbound from the encoder; do not open an inbound media port unless your own separate use case requires it. Restrict SSH or RDP administration to known source addresses or use an appropriate managed access method. AWS warns against allowing administrative access from everywhere in its security group guidance. Public addressing options are covered in Manage the IPv4 addresses for your EC2 instances.

3. Configure the encoder and stream settings
Configure the encoder to read the prerecorded file and send its output to the YouTube server URL with the stream key. Prefer RTMPS when the encoder supports it; YouTube describes it as an encrypted extension of RTMP. Its current live encoder settings guidance lists RTMP/RTMPS, H.264, H.265/HEVC or AV1 video, AAC or MP3 audio, constant bitrate (CBR), and frame rates up to 60 fps.

| Setting | YouTube guidance | How to apply it |
|---|---|---|
| Transport | RTMPS recommended | Use the secure ingest option if supported by your encoder. |
| Video bitrate | SDR H.264: 720p30 6 Mbps; 720p60 8 Mbps; 1080p30 10 Mbps; 1080p60 12 Mbps | These are YouTube recommendations, not guaranteed minimums. Match the output to the source and stable available upload bandwidth. |
| Rate control | CBR | Set constant bitrate if the encoder exposes this control. |
| Keyframe interval | 2 seconds recommended; do not exceed 4 seconds | Set the interval explicitly rather than relying on an encoder default. |
| SDR color | Rec. 709, 8-bit | Use these SDR values where applicable to the source and output. |
| Stereo audio | 44.1 kHz, 128 kbps recommended | Use AAC or MP3 as supported by the encoder. |
| 5.1 audio | AAC, 48 kHz, 384 kbps recommended | Use only if the source and intended stream are 5.1. |
For bandwidth planning, YouTube recommends 20% upload headroom above the stream bitrate. The encoder host’s sustained outbound capacity should therefore exceed the selected bitrate, not merely touch it. See YouTube streaming tips. These technical recommendations can change; consult YouTube’s encoder settings page when configuring a production stream.

4. Start the feed, verify it, and end the stream
- Start the encoder with the intended file, YouTube ingest URL, stream key, and output settings.
- In Live Control Room, confirm that the preview appears and inspect stream health, audio, and video before going live.
- When ready, click Go live for the scheduled stream, if applicable.
- Monitor the feed during playback. When finished, stop the encoder and end the YouTube stream as appropriate.
YouTube says streams under 12 hours are automatically archived; for longer streams, do not assume an archive will be available. Check the current workflow in Create a YouTube live stream with an encoder.
Operational choices and limits
Stream-copy/remux or transcode
If the file already uses a compatible format and settings, stream-copying or remuxing may avoid re-encoding; if its format or settings do not suit the stream, transcoding may be needed. The right choice depends on the file and encoder build. Validate the output with a preview and a sustained test before relying on it for a scheduled stream.

Public IP or private subnet with NAT
A public-subnet instance can provide a direct outbound path but requires careful exposure controls. A private-subnet instance with NAT keeps the host without a public address while still enabling outbound access. In either design, ensure the chosen YouTube ingest protocol is permitted by egress rules and keep administrative access narrow.

Troubleshooting
YouTube does not show an incoming preview
- Confirm the encoder is using the current server URL and stream key from the correct Live Control Room stream.
- Check DNS, subnet routing, NAT or internet-gateway configuration, security-group egress, and network ACL rules.
- Verify that the channel is eligible to stream and that the event is the one selected in Live Control Room.
Connection drops or stream health degrades
- Check sustained outbound capacity; YouTube recommends 20% headroom above the selected stream bitrate.
- Inspect CPU load if transcoding, and test whether a lower resolution, frame rate, or bitrate improves stability.
- Confirm that network rules allow the chosen RTMPS or RTMP connection and that the encoder is using the intended endpoint.
Video stutters or looks poor
- Use CBR and a two-second keyframe interval, staying at or below YouTube’s four-second maximum recommendation.
- Match the output resolution and frame rate to the source where practical; check the current YouTube bitrate guidance for that target.
- Determine whether the EC2 host is overloaded by transcoding; instance selection must be validated for the specific workload.
Audio is missing or incorrect
- Check the source file’s audio track and confirm the encoder maps it into the output.
- Use an audio codec supported by YouTube’s guidance, and verify sample rate and bitrate settings for stereo or 5.1.
- Listen to the Live Control Room preview before going live.
The stream key may be exposed
Reset the key in Live Control Room and update the encoder configuration. Do not store it in a public repository, shared command history, or broadly accessible log.
