Method Documentation
◆ deinit()
| - (void) deinit |
Deinit video player.
- Note
- Deinit and reinit video player between sessions to avoid old buffered frames to be displayed first.
◆ displayH264Nalus:()
| - (void) displayH264Nalus: | (NSData *) | nalus |
Display NALU(s)/video frame(s).
- Parameters
-
nalus NALUs to be displayed. This can be a single I-frame, P-frame, SPS, PPS, or a few NALUs together, such as for example a SPS, PPS and I-frame.
- Note
- For the video player to be able to display a frame it first needs to have received NALUs with both SPS and PPS, as well as an I-frame.
◆ initWithParentView:()
| - (id) initWithParentView: | (UIView *) | parentView |
Initialize and specify view to display video.
- Parameters
-
parentView View where the video will be displayed.
◆ setNbrFramesToDelay:()
| - (void) setNbrFramesToDelay: | (NSInteger) | nbrFramesToDelay |
Set the number of frames to delay video by.
- Parameters
-
nbrFramesToDelay Number of video frames to delay video by. For example if setting this number to 3 for a video stream at 15 fps, the added delay will be 200 ms.
- Note
- Ideally on the audio side, chunks of 20 ms of audio are used for streaming, which results in the audio delay being very small and not noticeable compared to video. But some embedded systems are not able to deal with such small audio chunks. As a result the length of chunks needs to be increased, which then makes the audio lag apparent, even while video is near instantaneous. Use this function to delay the video by the number of frames needed to match up with the audio.
◆ updateBounds()
| - (void) updateBounds |
Update video bounds tied to parent view.
- Note
- If the parent view is using auto-layout in a way that causes its bounds to change, its bounds may not show correctly until after viewDidAppear. If that is the case call updateBounds in viewDidAppear, and remove animation in your appearing view to avoid the video moving in case it shows up before viewDidAppear got called.
