HLS test stream with our video player

Errors

No URL given

There was no URL specified.

Cross Origin Resource Sharing (CORS) is not enabled

This means that the file could not be downloaded because of the same-origin-policy of browsers. To fix this problem, you must enable Access-Control-Allow-Origin on the streaming server.

The segment could not be decrypted

Decryption failed on the following segments. Read more about decryption in THEOplayer.

Could not retrieve file(s) from server

A succesfull download starts with code 2xx or 3xx. Details about codes

No endlist and not long enough

If there is no EXT-X-ENDLIST specified in the media manifests (= live stream), then the total duration MUST be at least three times the target duration.

The segment exceeds the allowed bandwidth

The size of a segment may not exceed that specified bandwidth in the master playlist.

Segments should have PAT/PMT available

Segments must have PAT/PMT present.

RAW audio should have ID3 data

Raw audio (aac / mp3) MUST have ID3 data. This is necessary because ID3 contains information about timestamps in the audio.

Recommendations

Manifest has both an invalid extension and content-type

Consider fixing at least one of the two:
Content type should be either application/vnd.apple.mpegurl, application/x-mpegurl or audio/mpegurl. OR the extension should be m3u8 or m3u.

Not all media are linked to streams

You can link to additional media from an EXT-X-STREAM-INF in the master playlist. For the link to be valid, the EXT-X-STREAM-INF needs to reference to one or multiple types (AUDIO, CLOSE-CAPTIONS, SUBTITLES, VIDEO) AND the identifier of the partition group (group-id) of the EXT-X-MEDIA. The coupled EXT-X-MEDIA must have the same type specified, as well as the group-id.
Read more in the spec.

Some #EXT-X-MEDIA do not have all the required attributes

Every #EXT-X-MEDIA specified in the master playlist should have a (correct) type (AUDIO, VIDEO, SUBTITLES or CLOSE CAPTIONS), a human readable NAME and a GROUP-ID.

No stream could be played at 3G connection speed

A regular 3G connection has a speed around 750 Kbps/sec.

Some #EXT-X-STREAM-INF do not have all the required attributes

Every #EXT-X-STREAM-INF specified in the master playlist should have a bandwidth specified. This helps THEOplayer deciding which quality is best suited for the internet connection of the user.

Some #EXT-X-STREAM-INF / #EXT-X-MEDIA in the master playlist have the same URI

Make sure that each #EXT-X-STREAM-INF / #EXT-X-MEDIA has an unique URI.

All media playlist should have the same target duration

Media manifests should have the same target duration. It might otherwise be hard to switch qualities.

Audio segments should have the same codec in each quality

If the codec of the audio is not everywhere the same, it might cause some compatibility issues in Chrome.

Segments in media playlist may not be longer than the target duration

Segments declared in the media manifests may not be longer than the target durations. Otherwise, it might give playback stalls.

Some segments declared in the live media manifest were shorter than half the target duration.

This might increase overhead for the live stream, because THEOplayer might ask more often for updates when some segments are a lot shorter.

All media playlists needs to have a target duration

Media playlists MUST have the EXT-X-TARGETDURATION set.
This tag specifies the maximum media segment duration.

Discontinuities must appear at the same point in all media playlist

The sum of the segments in each discontinuity of the media manifests were not equal. This could give problems when changing streaming qualities.

All media playlist should contain media sequence numbers

The EXT-X-MEDIA-SEQUENCE tag indicates the number of the first segment that appears in the media manifest. This is usually needed in a live stream.

Has some invalid discontinuity sequence numbers

All streams should have the same duration

The sum of the duration of the segments in all the media manifests should be the same. Otherwise it could trigger problems with switching qualities.

Segments should start with a key frame

Segments must start with a key frame. If there is no keyframe available, the player might skip until the next key frame is found.

Audio and video are not in sync

Video and audio should be in sync with each other in the PTS.

Segments should be in sync with each other

The different qualities / versions of the segments are not in sync (PTS) with each other. This might result in time jumps / stalls when switching qualities.

Successive PTS timestamps should be in sync with each other

PTS (presentation timestamps) should be updating correctly in orde to keep them in sync.
For example: if the first segment starts at 5 and the duration is 5, the next segment should start at 10.

Not a valid VTT-file

VTT subtitles must start with WEBVTT and should have X-TIMESTAMP-MAP specified. Otherwise it might not be recognized as a subtitle.

Segments should have the same codec as in the media manifest

Segments which do not have the right codec, might in some cases not be playable for the player.

Segments should have the same resolution as declared in the playlist manifest

The resolution specified in the master playlist (optional attribute) can help client user agents decide which download quality is best for them. Make sure that the information matches with the data in the segments.

Segments must be as long as in the media manifest

The duration of the segments (data) should be the same as specified in the media manifests. Otherwise the stream might go out of sync.

Some segments do not have the right content-type and extension

Some content-types might not be supported.
While THEOplayer supports more types, this tool tested for audio/aac, audio/mp3 and video/mp2t.

Safe extensions that we tested for are: .ts, .aac, .mp3 and .vtt, .webvtt
