92 |
* Quicktime has tracks and segments. A track is a continuous piece of
|
|
|
93 |
* multimedia content. The track is not always played from start to finish but
|
|
|
94 |
* instead, pieces of the track are 'cut out' and played in sequence. This is
|
|
|
95 |
* what the segments do.
|
|
|
96 |
*
|
|
|
97 |
* Inside the track we have keyframes (K) and delta frames. The track has its
|
|
|
98 |
* own timing, which starts from 0 and extends to end. The position in the track
|
|
|
99 |
* is called the media_time.
|
|
|
100 |
*
|
|
|
101 |
* The segments now describe the pieces that should be played from this track
|
|
|
102 |
* and are basically tupples of media_time/duration/rate entries. We can have
|
|
|
103 |
* multiple segments and they are all played after one another. An example:
|
|
|
104 |
*
|
|
|
105 |
* segment 1: media_time: 1 second, duration: 1 second, rate 1
|
|
|
106 |
* segment 2: media_time: 3 second, duration: 2 second, rate 2
|
|
|
107 |
*
|
|
|
108 |
* To correctly play back this track, one must play: 1 second of media starting
|
|
|
109 |
* from media_time 1 followed by 2 seconds of media starting from media_time 3
|
|
|
110 |
* at a rate of 2.
|
|
|
111 |
*
|
|
|
112 |
* Each of the segments will be played at a specific time, the first segment at
|
|
|
113 |
* time 0, the second one after the duration of the first one, etc.. Note that
|
|
|
114 |
* the time in resulting playback is not identical to the media_time of the
|
|
|
115 |
* track anymore.
|
|
|
116 |
*
|
|
|
117 |
* Visually, assuming the track has 4 second of media_time:
|
|
|
118 |
*
|
|
|
119 |
* (a) (b) (c) (d)
|
|
|
120 |
* .-----------------------------------------------------------.
|
|
|
121 |
* track: | K.....K.........K........K.......K.......K...........K... |
|
|
|
122 |
* '-----------------------------------------------------------'
|
|
|
123 |
* 0 1 2 3 4
|
|
|
124 |
* .------------^ ^ .----------^ ^
|
|
|
125 |
* / .-------------' / .------------------'
|
|
|
126 |
* / / .-----' /
|
|
|
127 |
* .--------------. .--------------.
|
|
|
128 |
* | segment 1 | | segment 2 |
|
|
|
129 |
* '--------------' '--------------'
|
|
|
130 |
*
|
|
|
131 |
* The challenge here is to cut out the right pieces of the track for each of
|
|
|
132 |
* the playback segments. This fortunatly can easily be done with the SEGMENT
|
|
|
133 |
* events of gstreamer.
|
|
|
134 |
*
|
|
|
135 |
* For playback of segment 1, we need to provide the decoder with the keyframe
|
|
|
136 |
* (a), in the above figure, but we must instruct it only to output the decoded
|
|
|
137 |
* data between second 1 and 2. We do this with a SEGMENT event for 1 to 2, time
|
|
|
138 |
* position set to the time of the segment: 0.
|
|
|
139 |
*
|
|
|
140 |
* We then proceed to push data from keyframe (a) to frame (b). The decoder
|
|
|
141 |
* decodes but clips all before media_time 1.
|
|
|
142 |
*
|
|
|
143 |
* After finishing a segment, we push out a new SEGMENT event with the clipping
|
|
|
144 |
* boundaries of the new data.
|
|
|
145 |
*
|
|
|
146 |
* This is a good usecase for the GStreamer accumulated SEGMENT events.
