chrisyue / php-m3u8 Goto Github PK

您好，最近有个 HLS 反代的需求需要用到您的库，使用中发现索引中的多条（音、字幕）轨只能被识别到最后一条。

(原始 M3U8 索引文件)

(Parse 后的数组，只匹配了最后一个 EXT-X-MEDIA 数据)

大大您好，我又来提 BUG 了…

这次发现的问题是 DumperFacade 组件在利用 dump() 方法生成播放列表的时候，会把原列表上的 EXT-X-MEDIA-SEQUENCE 字段无视掉，这个参数对于直播来说非常重要。如果该字段丢失，会令播放器出现断流的问题。

(原始播放列表)

(经过 Parse 后再重新生成的播放列表，可以看到 EXT-X-MEDIA-SEQUENCE 字段被舍弃了)

I have a shared server
How can i download and use it without composer?

解析以后，所有的mediaSegments内的元素属性都是只读的，比如Inf标签，我想遍历这些元素，找出Inf标签的CCTV-1的TITLE，然后把uri进行修改和替换，貌似做不到。为什么这么设计呢?
如果parse后只能用自定义 dump函数的方法控制输出，我直接按行文本查找都比较快。
我现在自定义了我的Inf标签类，把这些属性都改成可读写了，毕竟我读取列表不是为了只是解析一下然后就dump成文本的。

Some resources files trying use Byterange from Tag:

use Chrisyue\PhpM3u8\Data\Value\Tag\Byterange;

files:
resources/tagValueParsers.php
resources/attributeValueParsers.php

The namespace for Byterange is Value.

https://tools.ietf.org/html/rfc8216#section-4.3.2.1

...
duration is a decimal-floating-point or decimal-integer number
(as described in Section 4.2) that specifies the duration of the
Media Segment in seconds.
...

https://tools.ietf.org/html/rfc8216#section-4.2

decimal-integer: an unquoted string of characters from the set
[0..9] expressing an integer in base-10 arithmetic in the range
from 0 to 2^64-1 (18446744073709551615). A decimal-integer may be
from 1 to 20 characters long.

I know that tag EXT-X-MEDIA is not ready in version 2.3.1, but i want to get it done by myself.
But where is the best place shoud I put my code in the php-m3u8 library?

• Place in M3u8::__construct() and where?
• Place in Segment::__construct() and where?

Hi, what does dumping do and do you have any method that would add / append new data?

百度了一圈m3u8，没想明白

A lot of m3u/m3u8 lists have a duration of -1. Your script checks if duration is <= 0 and throws an error.

InvalidArgumentException
$duration should be greater than 0

I think Segment is missing setUri function?

https://tools.ietf.org/html/rfc8216#section-4.1

Lines that start with the character '#' are either comments or tags.
Tags begin with #EXT. They are case sensitive. All other lines that
begin with '#' are comments and SHOULD be ignored.

This test case will fail

programmer have always hard time to explain and create a simple demo php file

When I wrote the code according to the implementation example of READEME, the following Exception occurred.

[App\Exceptions\Handler] InvalidArgumentException: $offset should be an integer greater than 0 in /var/www/mgsplayer_api/vendor/chrisyue/php-m3u8/src/Data/Value/Tag/Byterange.php:33

The master manifest can be parsed without any problems, but only the media manifest has an Exception.
Do you know what caused it?

The following is a partial excerpt of the contents of the manifest file that is about to be parsed.

When parsing a master.m3u8 in some sub directory, this library returns the URIs of sub-streams as-is. Which means they can be relative to the directory where the master.m3u8 is located. It would be great if there was a property that gives the full path to the sub-stream. E.g.:

$master = $parser->parse(new FileStream('../download/master.m3u8'));
print_r($master['EXT-X-STREAM-INF'][0]);

This currently just returns:

[uri] => playlist-1280.m3u8

So I have to figure out myself that this is relative to ../download/.

I'd like to have it also spit out e.g.:

[uri] => playlist-1280.m3u8
[filepath] => ../download/playlist-1280.m3u8
