153 * Quicktime has tracks and segments. A track is a continuous piece of
154 * multimedia content. The track is not always played from start to finish but
155 * instead, pieces of the track are 'cut out' and played in sequence. This is
156 * what the segments do.
158 * Inside the track we have keyframes (K) and delta frames. The track has its
159 * own timing, which starts from 0 and extends to end. The position in the track
160 * is called the media_time.
162 * The segments now describe the pieces that should be played from this track
163 * and are basically tuples of media_time/duration/rate entries. We can have
164 * multiple segments and they are all played after one another. An example:
166 * segment 1: media_time: 1 second, duration: 1 second, rate 1
167 * segment 2: media_time: 3 second, duration: 2 second, rate 2
169 * To correctly play back this track, one must play: 1 second of media starting
170 * from media_time 1 followed by 2 seconds of media starting from media_time 3
173 * Each of the segments will be played at a specific time, the first segment at
174 * time 0, the second one after the duration of the first one, etc.. Note that
175 * the time in resulting playback is not identical to the media_time of the
178 * Visually, assuming the track has 4 second of media_time:
181 * .-----------------------------------------------------------.
182 * track: | K.....K.........K........K.......K.......K...........K... |
183 * '-----------------------------------------------------------'
185 * .------------^ ^ .----------^ ^
186 * / .-------------' / .------------------'
188 * .--------------. .--------------.
189 * | segment 1 | | segment 2 |
190 * '--------------' '--------------'
192 * The challenge here is to cut out the right pieces of the track for each of
193 * the playback segments. This fortunately can easily be done with the SEGMENT
194 * events of GStreamer.
196 * For playback of segment 1, we need to provide the decoder with the keyframe
197 * (a), in the above figure, but we must instruct it only to output the decoded
198 * data between second 1 and 2. We do this with a SEGMENT event for 1 to 2, time
199 * position set to the time of the segment: 0.
201 * We then proceed to push data from keyframe (a) to frame (b). The decoder
202 * decodes but clips all before media_time 1.
204 * After finishing a segment, we push out a new SEGMENT event with the clipping
205 * boundaries of the new data.
207 * This is a good usecase for the GStreamer accumulated SEGMENT events.
