示例1: seekToFrame
bool VideoDecoder::seekToFrame(uint frame) {
if (!isSeekable())
return false;
VideoTrack *track = 0;
for (TrackList::iterator it = _tracks.begin(); it != _tracks.end(); it++) {
if ((*it)->getTrackType() == Track::kTrackTypeVideo) {
// We only allow seeking by frame when one video track
// is present
if (track)
return false;
track = (VideoTrack *)*it;
}
}
// If we didn't find a video track, we can't seek by frame (of course)
if (!track)
return false;
Audio::Timestamp time = track->getFrameTime(frame);
if (time < 0)
return false;
return seek(time);
}
示例2: setEndFrame
void VideoDecoder::setEndFrame(uint frame) {
VideoTrack *track = 0;
for (TrackList::iterator it = _tracks.begin(); it != _tracks.end(); it++) {
if ((*it)->getTrackType() == Track::kTrackTypeVideo) {
// We only allow this when one video track is present
if (track)
return;
track = (VideoTrack *)*it;
}
}
// If we didn't find a video track, we can't set the final frame (of course)
if (!track)
return;
Audio::Timestamp time = track->getFrameTime(frame + 1);
if (time < 0)
return;
setEndTime(time);
