play-from-disk
play-from-disk demonstrates how to send video and/or audio to your browser from files saved to disk.
For an example of playing H264 from disk see play-from-disk-h264
Instructions
Create IVF named output.ivf that contains a VP8 track and/or output.ogg that contains a Opus track
ffmpeg -i $INPUT_FILE -g 30 -b:v 2M output.ivf
ffmpeg -i $INPUT_FILE -c:a libopus -page_duration 20000 -vn output.ogg
Note: In the ffmpeg command which produces the .ivf file, the argument -b:v 2M specifies the video bitrate to be 2 megabits per second. We provide this default value to produce decent video quality, but if you experience problems with this configuration (such as dropped frames etc.), you can decrease this. See the ffmpeg documentation for more information on the format of the value.
Download play-from-disk
export GO111MODULE=on
go get github.com/pion/webrtc/v3/examples/play-from-disk
Open play-from-disk example page
jsfiddle.net you should see two text-areas and a 'Start Session' button
Run play-from-disk with your browsers SessionDescription as stdin
The output.ivf you created should be in the same directory as play-from-disk. In the jsfiddle the top textarea is your browser, copy that and:
Linux/macOS
Run echo $BROWSER_SDP | play-from-disk
Windows
- Paste the SessionDescription into a file.
- Run
play-from-disk < my_file
Input play-from-disk's SessionDescription into your browser
Copy the text that play-from-disk just emitted and copy into second text area
Hit 'Start Session' in jsfiddle, enjoy your video!
A video should start playing in your browser above the input boxes. play-from-disk will exit when the file reaches the end
Congrats, you have used Pion WebRTC! Now start building something cool
