Resuming a video

[imilne]

The following "seems" to work:

Code:

Int32 duration = new Int32();
int position = PlaybackPositionHelper.GetPlaybackPosition(path, out duration);

PluginHelperFactory.GetPluginHelper().PlayVideoFile(path);

IPlaybackProxy proxy = PluginHelperFactory.GetPluginHelper().GetPlaybackProxy();
proxy.SetPosition(position);

But like most code pulled from the innards of an API I don't really understand, I'd like to know if it's ok?

Thanks

Yep, that should be ok. From memory the Video Library does the same thing.

Excellent, thanks.

From memory the Video Library does the same thing.

That's pretty much how I worked it out. A combination of browsing the API and looking at the log messages produced by the Video Library. That's what gave the clue to setting the resume position *after* starting the video :confused:

I can't find PlaybackPositionHelper in the NPVR API. Is there something else in the API now that we can use to get this information for a plugin or do we have to read the database directly? Thanks.

PlaybackPositionHelper is still there. It was never really intended to be part of the public api, but you can use it by adding a reference to NShared.dll.

Here is how I use it in iGL if the file is renamed and it was played in-progress

Code:

if (File.Exists(source) == false && destTS != null)
                    {
                        int duration = -1;
                        int position = PlaybackPositionHelper.GetPlaybackPosition(source, out duration);
                        if (duration > 0)
                        {
                            PlaybackPositionHelper.StorePlaybackPosition(destTS, position, duration);
                            PlaybackPositionHelper.DeletePlaybackPosition(source);
                        }

The trick for me was not using the return code.

IPlaybackProxy.SetPosition(); works fine in my plugin when running in NPVR, however, it doesn't work and seems to stop playback when running my plugin in the XNEWA web client. Is there another way to set the playback position in this case? Thanks.

Unfortunately playback via the webclient isn't managed by NextPVR. That is done directly by the client, and not something NextPVR has any control over. The IPlaybackProxy wont be usable there.

Resume from the Recordings list popup works from the web client so is it using something special?

[sub]

When you play a video file using the webclient, the web server passes an activity to the client effectively saying "play file x". When you do a resume, it does the same thing, but instead it passes a more detailed activity "play file x from position t". We still have no control over the video when it's playing, or no idea where it's up to, but you can get it to start playback from a particular location.

You can trigger the same thing from a plugin using:

Code:

Hashtable resumeMetaData = new Hashtable();
                            resumeMetaData["RESUME_FROM"] = position;
                            PluginHelperFactory.GetPluginHelper().PlayVideoFile(filename, resumeMetaData);
