+- H264 = H.264 = AVC (Advanced Video Coding)
+- H265 = H.265 = HEVC (High Efficiency Video Coding)
+- PCMU = G.711 PCM (A-law) = PCM A-law (`alaw`)

+
+## Built-in transcoding
+
+There are no plans to embed complex transcoding algorithms inside go2rtc. [FFmpeg source](#source-ffmpeg) does a great job with this. Including [hardware acceleration](https://github.com/AlexxIT/go2rtc/wiki/Hardware-acceleration) support.
+
+But go2rtc has some simple algorithms. They are turned on automatically, you do not need to set them up additionally.
+
+**PCM for MSE/MP4/HLS**
+
+Go2rtc can pack `PCMA`, `PCMU` and `PCM` codecs into an MP4 container so that they work in all browsers and all built-in players on modern devices. Including Apple QuickTime:
+
+```
+PCMA/PCMU => PCM => FLAC => MSE/MP4/HLS
+```
+
+**Resample PCMA/PCMU for WebRTC**
+
+By default WebRTC support only `PCMA/8000` and `PCMU/8000`. But go2rtc can automatically resample PCMA and PCMU codec with with a different sample rate. Also go2rtc can transcode `PCM` codec to `PCMA/8000`, so WebRTC can play it:
+
+```
+PCM/xxx => PCMA/8000 => WebRTC
+PCMA/xxx => PCMA/8000 => WebRTC
+PCMU/xxx => PCMU/8000 => WebRTC
+```
+
+**Important**
+
+- FLAC codec not supported in a RTSP stream. If you using Frigate or Hass for recording MP4 files with PCMA/PCMU/PCM audio - you should setup transcoding to AAC codec.
+- PCMA and PCMU are VERY low quality codecs. Them support only 256! different sounds. Use them only when you have no other options.
