1. 从github下载依赖的sdk目录，与media-server平级
|
||||
git clone https://github.com/ireader/sdk sdk
|
||||
|
||||
2. 分别编译libaio/libhttp/libmpeg/libflv/libhls
|
||||
make -C sdk/libaio && make -C sdk/libhttp && make -C media-server/libmpeg && make -C media-server/libflv && make -C media-server/libhls
|
||||
|
||||
3. cd media-server/libhls/test目录下执行make
|
||||
|

// 1. What kinds of encoders are supported?
|
||||
// H.264 video and AAC audio (HE-AAC or AAC-LC).
|
||||
// 2. What are the specifics of the video and audio formats supported?
|
||||
// Video: H.264 Baseline Level 3.0, Baseline Level 3.1, Main Level 3.1, and High Profile Level 4.1.
|
||||
// Audio: HE-AAC or AAC-LC up to 48 kHz, stereo audio
|

// MP3 (MPEG-1 Audio Layer 3) 8 kHz to 48 kHz, stereo audio
|
||||
// AC-3 (for Apple TV, in pass-through mode only)
|
||||
|
||||
// 3. What duration should media files be?
|
||||
// A duration of 10 seconds of media per file seems to strike a reasonable balance for most broadcast content.

// that segment.
|

|
||||
// 6.3.3. Playing the Playlist file
|
||||
// 1. If the EXT-X-ENDLIST tag is not present, the client SHOULD NOT
|
||||
// choose a segment which starts less than three target durations from
|
||||
// the end of the Playlist file.
|
||||
// 2. The client SHOULD attempt to load media segments in advance of when
|
||||
// they will be required for uninterrupted playback to compensate for
|
||||
// temporary variations in latency and throughput.
|
||||
// 3. The client MUST be prepared to reset its parser(s) and decoder(s)
|
||||
// before playing a media segment that has an EXT-X-DISCONTINUITY tag
|
||||
// applied to it.
|
||||
|
||||
// 6.3.4. Reloading the Playlist file
|
||||
// 1. The client MUST periodically reload the Media Playlist file unless it
|
||||
// contains the EXT-X-ENDLIST tag.
|
||||
// 2. if Playlist file changed since the last time it was loaded, the client MUST wait for
|
||||
// at least the target duration before attempting to reload the Playlist file again
|
||||
// 3. if Playlist file not changed then it MUST wait for a period of one-half the target
|
||||
// duration before retrying
