If you've completed creating a channel for VOD streaming and linkage settings with the CDN platform, you can play content with a playback path URL to check the implementation status of your streaming service. You can set up the playback's start point and end point to apply file trimming or subtitles.
Caution
- Do not use the same file name when you're replacing a source media file in service. If you must use the same file name, perform a CDN purge after at least 10 minutes after replacing the file to remove the cached existing content.
- If there are characters such as #, $, and ; included in the original file name, you cannot play protocol through the playback path URL. Be careful with the special characters on the original file name.
- VOD Station supports audio streaming, and you must use m4a files encoded through VOD Station or m4a files that meet the VOD Station Channel input specifications.
- For VOD Station Channel input specifications, see the user guide.
- m4a recording files created in Live Station are segment files and do not support VOD Streaming, making playback impossible.
Check playback path URL
The structure for a playback path URL used in VOD Station is as follows.
| Scheme | CDN domain | Streaming protocol | File name | Manifest |
|---|---|---|---|---|
https:// | example.cdn.ntruss.com | /hls /dash | /example/example.mp4 | /index.m3u8/manifest.mpd |
| URL Scheme | Playback CDN domain | Streaming protocol of the created channel | Object Storage Name of the media file to be played, including bucket and folder path | Manifest file for streaming |
CDN playback path URL
If you've created a CDN when creating a channel, you can play it by referring to the CDN playback path URL in the channel information. Select a channel to play in the channel list, click the [Channel information] button, and check the URL from the information popup window's CDN playback path area.
- URL Template:
https://example.cdn.ntruss.com/[protocol]/[encryptedBucketName]/[path]/[video filename]/[manifest]
CDN Playback path URL separately created
If you haven't created a CDN together with a channel, but you created one separately, the channel information won't show the CDN playback path URL. Check the created 'CDN s service domain from the CDN list, and replace the [cdnDomain] part in the URL template to play the content.
- URL Template:
https://[cdnDomain]/[protocol]/[encryptedBucketName]/[path]/[video filename]/[manifest]
Create playback path URL
If you've created a Global Edge when creating a channel, you can automatically create a CDN playback path URL for each content. To create a playback path URL, follow these steps:
- In the NAVER Cloud Platform console, click the Services > Media > VOD Station menus in order.
- Click the Channel menu, and select a channel from the channel list.
- From the channel's content list, click the [Create HLS URL] or [Create DASH URL] button of the content for which you want to create the automatic URL.
- You'll be directed to the created URL, and the content will be played.
Content playback
You can play a channel's content to check the implementation status of your VOD streaming service. Play content referring to the following example.
Single bitrate playback
- Since the file existing without a separate folder under the vod-5100k.mp4 playback
bucket in the guide bucket is played, omit the [path] part of the URL Template.
URL Template:https://[cdnDomain]/[protocol]/[encryptedBucketName]/[path]/[video filename]/[manifest]- HLS:
https://example.cdn.ntruss.com/hls/guide/vod-5100k.mp4/index.m3u8 - DASH:
https://example.cdn.ntruss.com/dash/guide/vod-5100k.mp4/manifest.mpd
- HLS:
- Add the folder name of the bucket to the [path] part of the vod-5100k.mp4 playback
URL Template in the 1-depth folder in the guide bucket.
URL Template:https://[cdnDomain]/[protocol]/[encryptedBucketName]/[path]/[video filename]/[manifest]- HLS:
https://example.cdn.ntruss.com/hls/guide/1-depth/vod-5100k.mp4/index.m3u8 - DASH:
https://example.cdn.ntruss.com/dash/guide/1-depth/vod-5100k.mp4/manifest.mpd
- HLS:
Adaptive bitrate playback
Media files to be played with adaptive bitrate should all be located in the same folder.
- Use comma (,) as the classifier for each file in the guide bucket, such as vod-5400k.mp4, vod-2400k.mp4, vod-1200k.mp4,
vod-0900k.mp4, vod-0600k.mp4, vod-0300k.mp4 playback prefix, and suffix. Add .smil classifying that it is an abr request after the suffix.
Media file's prefix: vod-
media file’s suffix: k.mp4
URL Template:https://[cdnDomain]/[protocol]/[encryptedBucketName]/[path]/[prefix],[video filenames],[suffix].smil/[manifest]- HLS:
https://example.cdn.ntruss.com/hls/guide/abr/vod-,5400,2400,1200,0900,0600,0300,k.mp4.smil/master.m3u8
(Use master.m3u8, not index.m3u8, as the manifest when making HLS requests.) - DASH:
https://example.cdn.ntruss.com/dash/guide/abr/vod-,5400,2400,1200,0900,0600,0300,k.mp4.smil/manifest.mpd
- HLS:
- If playback file names of vod-0600k.mp4, vod-0300k.mp4, and svod-360p.mp4 in the guide bucket are different,
place a space between the prefix and suffix, and add a comma (,).
Media file's prefix: none
media file’s suffix: none
URL Template:https://[cdnDomain]/[protocol]/[encryptedBucketName]/[path]/[prefix],[video filenames],[suffix].smil/[manifest]- HLS:
https://example.cdn.ntruss.com/hls/guide/abr/,vod-0600k.mp4,vod-0300k.mp4,svod-360p.mp4,.smil/master.m3u8 - DASH:

Crop media file
You can specify playback points in a media file and use the cropping feature.
Specify playback start point
The following example demonstrates how to play a file by specifying a VOD's playback start point (vodStart) at 10 seconds. The time unit is millisecond (1 second = 1000 milliseconds). The file crop option is located behind [protocol]/[encryptedBucketName].
- Single bitrate playback

Subtitle settings
You can apply subtitles to video content to be released. The following subtitle formats are supported.
| Input | Output |
|---|---|
| VTT, SRT, DFXP, TTML, CAP | VTT |
Specify location of video and subtitle files
The location of video and subtitle files is based on the [path] before the comma (,) where the ABR URL begins.
https://example.cdn.ntruss.com/[protocol]/[encryptedBucketName]/[path]/,[video files],lang/[lang code]/[subtitle filename],.smil/master.m3u8
The video and subtitle files should be located under /[path].
Subtitle language settings
Language separation is classified as [lang code] within the URL.
https://example.cdn.ntruss.com/[protocol]/[encryptedBucketName]/[path]/,[video files],lang/[lang code]/[subtitle filename],.smil/master.m3u8
Note
Language code name must be 3 letters with ISO 639-3. See ISO639-3 code list.
