This error message or more frequently occurs when your access is being blocked via a proxy server or a school / corporate firewall. In other words, currently the video cannot be streamed in your region. But there may be many other reasons. Therefore, the solutions may be diverse from each other.
The following solutions apply to browser issue:
1. Download Google Chrome or Mozilla Firefox to have a try. If it has no error, just use it as an IE (Internet Explorer) alternative for online video or movie playing and streaming. Not taking IE as the core, such browser will not conflict with IE.
2. Since it is may be the reason of hardware, such as not enough memory, CPU heating and slow internet speed, we suggest you not to do other operation on your computer during M3U8 streaming. Otherwise, enable hardware (GPU) acceleration or upgrade your hardware.
3. Since it is may be the problem of the website, you can go back in a different time.

The following solutions apply to player issues:
In other cases, the 'M3U8 cannot load' problem is led by your player. If that is the case, please enable Flash in your Browser. If it is still not working, try to change to another browser, or, you can turn to the following posts and threads:
If you have a URL to the .M3U8 file and the files it references are also online, you can use 5KPlayer or HSLPlayer.net to open it.
But if you have an M3U8 file stored on your computer or some other device, you are suggested to use VLC, Apple's iTunes media player, Windows Media Player or 5KPlayer.
Convert M3U8 to MP4 or Other Format
An M3U8 file is just a plain text file. Opening such file in Notepad only allows you to read the file references, but no to actually play any of these music files, because text editors are different from media player programs.
M3U8 playlist or folder often consists of several short (.ts) video clips, so you may fail to play the playlist or folder directly. But with the following solution (converting M3U8 to MP4), it is possible to play an M3U8 video folder successfully.
Simply put, the solution goes like: input the folder > merge the scattered video files > convert the file to MP4 or other format.
Specifically, refer to the following steps for details:
What you will need:
1. A M3U8 folder that has already stored on your hard drive of computer.
2. A video processing tool, typically, VideoProc, downloaded and installed on your PC or Mac.
VideoProc - More Than an M3U8 Conversion Tool
- Convert videos from or to M3U8 format or virtually any video format.
- Process, cut, crop, merge, rotate, flip, effect, watermark, GIF, etc.
- Compress, resize video files with minimum quality loss.
- Free download video/music from YouTube and 1000+ sites.
- Convert DVDs, audios. Record desktop screen and / or webcam.
Step 1. Load the M3U8 folder as the input.
Open VideoProc, select 'Video', click '+ Video Folder' to add the source folder, or click '+ Video' to add all the TS video files in sequence from the folder.
Note: Due to the particularity of M3U8 playlist, some files might not able to be loaded successfully. But in most cases, you only need the successfully loaded files.
Add subtitle file from local drive or online as steps shown above.
Step 2. Merge the files.
In Toolbox of VideoProc, choose Merge option.
Step 3. Choose an output format.
Click on Video button on the bottom and go to Target Format where you have hundreds of options to choose as the output format, including General Profiles like MP4, Apple Device like iPhone Xs, Android Pad like Amazon Fire 7, Sony Device like PlayStation 4 Video, YouTube Video and so on.
Step 4. Make settings or editing if necessary.
You can do more things with VideoProc, including compress the video file, crop, cut, split, rotate, add effect, etc. It also enables you to make full use of GPU and CPU for acceleration.

Create M3U8 for https Streaming Everywhere
M3U is a computer file format for a multimedia playlist. If the text is encoded in UTF-8, is will ended with 'm3u8' file extension. Commonly, an M3U8 file format can be used for creating a single-entry playlist file for streaming on the internet easily. Therefore, M3U8 files are widely used in website downloads, emailing and internet radio.
Creating M3U8 virtually equals https streaming everywhere. And VideoProc comes with the function of creating M3U8 files from any ordinary video.
Without a steep learning curve, you can get to know how to create an M3U8 folder or files:
Launch VideoProc > Video > + Video > add a source video file from your computer > Toolbox > M3U8 > RUN
After the video to M3U8 conversion finishes, you will get a complete M3U8 folder that is easy to be streamed everywhere.

What is M3U8: M3U8 is an audio playlist file that is a plain text file useful on video and audio players. An M3U8 file describes and specifies the locations of media files and/or entire folder with absolute paths, relative paths, and URLs.
What is M3U URL: M3U was originally developed by Fraunhofer for use with their Winplay3 software, but is now supported by various media player applications. Fernandes guitar serial number dating. It is commonly used to point media players to (online) audio and video sources.

M3U (MP3 URL[1][2] or Moving Picture Experts Group Audio Layer 3Uniform Resource Locator[3] in full) is a computer file format for a multimedia playlist. One common use of the M3U file format is creating a single-entry playlist file pointing to a stream on the Internet. The created file provides easy access to that stream and is often used in downloads from a website, for emailing, and for listening to Internet radio.
Although originally designed for audio files, such as MP3, it is commonly used to point media players to audio and video sources, including online sources. M3U was originally developed by Fraunhofer for use with their Winplay3 software,[4] but numerous media players and software applications now support the format.
Careless handling of M3U playlists has been the cause of vulnerabilities in many music players such as VLC media player,[5]iTunes,[6]Winamp,[7] and many others.[8]
File format[edit]
There is no formal specification for the M3U format; it is a de facto standard.
An M3U file is a plain text file that specifies the locations of one or more media files. The file is saved with the 'm3u' filename extension if the text is encoded in the local system's default non-Unicode encoding (e.g., a Windows codepage), or with the 'm3u8' extension if the text is UTF-8 encoded.[9]
Each entry carries one specification. The specification can be any one of the following:
- an absolute local pathname; e.g., C:My MusicHeavysets.mp3
- a local pathname relative to the M3U file location; e.g. Heavysets.mp3
- a URL

Extended M3U[edit]
The M3U file can also include comments, prefaced by the '#' character. In extended M3U, '#' also introduces extended M3U directives which are terminated by a colon ':' if they support parameters.

---|---|---|---|---|
#EXTM3U | file header, must be the first line of the file | #EXTM3U | 1× | Yes |

Apple used the extended M3U format as a base for their HTTP Live Streaming (HLS)[12] which was standardized in 2017 by the IETF as RFC 8216.[13] Therein, a master playlist references segment playlists which usually contain URLs for short parts of the media stream. Some tags only apply to the former type and some only to the latter type of playlist, but they all begin with

M3U8[edit]
The Unicode version of M3U is M3U8, which uses UTF-8-encoded characters. M3U8 files are the basis for the HTTP Live Streaming (HLS) format originally developed by Apple to stream video and radio to iOS devices, and which is now a popular format for Dynamic Adaptive Streaming over HTTP (DASH) in general.
The 2015 proposal for the HLS playlist format uses UTF-8 exclusively and does not distinguish between the 'm3u' and 'm3u8' file name extensions.[14]
Internet media types[edit]
The only Internet media type registered for M3U and M3U8 is
application/vnd.apple.mpegurl
, registered in 2009 and only referring to the playlist format as used in HLS applications.[15][16]The current proposal for the HLS playlist format acknowledges two media types which it treats as equivalent:
application/vnd.apple.mpegurl
and audio/mpegurl
.[14] Likewise, these are the two types recommended for HLS use by Microsoft.[17]For non-HLS applications, no media types were standardized or registered with the IANA, but a number of media types are nonetheless associated with the historical and ongoing use of the M3U and M3U8 formats for general playlists:
application/mpegurl
application/x-mpegurl
audio/mpegurl
audio/x-mpegurl
[1][2]
These types, plus
application/vnd.apple.mpegurl
and application/vnd.apple.mpegurl.audio
, are supported for HLS applications by (for example) Microsoft's Windows 10[17] and Internet Explorer 9,[18] and LG's WebOS.[19]Examples[edit]
How To Play M3u8 Files
- Example 1
This is an example of an extended M3U file on the Windows platform. Sample.mp3 and Example.ogg are the media files. 123 and 321 are the lengths in seconds.[20] A length of -1 or 0 may be used when the media file is a streaming file, as there is no actual, predefined length value. The value after the length is the title to be shown, which is generally the same as the location of the file which is on the second line. On the Mac OS X and Linux platforms, Unix paths are used.
- Example 2
This example shows how to create an m3u file linking to a specified directory (for example, a flash drive, or CD-ROM). The m3u file should contain only one string: the path to the directory. After starting, the media player will play all contents of the directory:
- Example 3
Here is another example, using relative format. The M3U file is placed in the same directory as the music, and directories must be preserved when moving the playlist to another device if subdirectories are used. This method is more flexible, as it does not rely on the file path staying the same.
This is the same file as above, saved as sample.m3u in C:Documents and SettingsUserMy Music
This format in an M3U allows copying to another device for playback. All files and directories referred to must also be copied. Bradley hand bold italic font free download.
- Example 4
Here is a mixed example:
Notes:
- Alternative and Classical are sub-directories of the directory that this playlist is stored in.
- 'Song' and 'New Song' are in sub-directories of the directory that this playlist is stored in.
- 'Stuff' is in the same directory that the playlist is stored in.
- 'Foo' is in the specified (Windows) volume and directory, which may or may not be the same directory the playlist is in.
- 'Bar' is in a different directory at the same level as the playlist directory. The double-dots reference the parent directory of the playlist directory, then into the sub-directory 'Other Music' to reach 'Bar'.
- 'Listen' is a Shoutcast stream.
- 'Mine' is an MP3 stored on a web server.
- Example 5
References to other M3U playlists, for example, are generally not well-supported.
- Example 6
The following is an example of a M3U playlist file for 'Jar of Flies' album by 'Alice in Chains' that was created by Mp3tag with the following custom option settings:[21][22][23]
- playlist extended info format =
'%artist% - %title%'
- playlist filename format =
'%artist%_%album%_00_Playlist.m3u'
- tag to filename conversion format =
'%artist%_%album%_$num(%track%,2)_%title%'
