GStreamer also supports reading streams with WebRTC/WHEP, although track codecs must be specified in advance through the `video-caps` and `audio-caps` parameters. Furthermore, if audio is not present, `audio-caps` must be set anyway and must point to a PCMU codec. For instance, the command for reading a video-only H264 stream is:
```sh
gst-launch-1.0 whepsrc whep-endpoint=http://127.0.0.1:8889/stream/whep use-link-headers=true \
video-caps="application/x-rtp,media=video,encoding-name=H264,payload=127,clock-rate=90000" \
audio-caps="application/x-rtp,media=audio,encoding-name=PCMU,payload=0,clock-rate=8000" \
! rtph264depay ! decodebin ! autovideosink
```
While the command for reading an audio-only Opus stream is:
```sh
gst-launch-1.0 whepsrc whep-endpoint="http://127.0.0.1:8889/stream/whep" use-link-headers=true \
audio-caps="application/x-rtp,media=audio,encoding-name=OPUS,payload=111,clock-rate=48000,encoding-params=(string)2" \
! rtpopusdepay ! decodebin ! autoaudiosink
```
While the command for reading a H264 and Opus stream is:
```sh
gst-launch-1.0 whepsrc whep-endpoint=http://127.0.0.1:8889/stream/whep use-link-headers=true \
video-caps="application/x-rtp,media=video,encoding-name=H264,payload=127,clock-rate=90000" \
audio-caps="application/x-rtp,media=audio,encoding-name=OPUS,payload=111,clock-rate=48000,encoding-params=(string)2" \
! decodebin ! autovideosink
```
#### VLC
VLC can read a stream from the server in multiple ways (RTSP, RTMP, HLS, SRT). The recommended one consists in reading with [RTSP](#rtsp):
