<p:media> with StreamedContent Not Rendering

tshuba · 19 Jun 2017, 16:36

Hello all,

Looking for some troubleshooting suggestions. I'm following the pattern of what's been documented several times, using StreamedContent with my PF components. I have an application scoped bean that I use to return streamed content for images (<p:graphicImage/>) , and that part works perfectly.

However, when trying to return content for the <p:media/> component from the same bean, it's acting very strangely.

My bean annotations as I said:

Code: Select all

@ApplicationScoped
@Named("newsImageHelper")
public class NewsImageHelper {

The XHTML source with a few hardcoded parameter values just to simplify.

Code: Select all

                    
<p:media value="#{newsImageHelper.video}" width="100%" height="300" player="quicktime">
         <f:param name="filename" value="mjwebsite.mp4" />
         <f:param name="foldername" value="40" />     
</p:media>

Here is the simple method within my NewsImageHelper class. I threw in a few System.outs to show that it's never even hitting the "else" clause. The phaseId is in the RENDER_RESPONSE phase for the first 3 invocations, then its seems to lose the context???

Code: Select all

   
 public StreamedContent getVideo() throws IOException {
        System.out.println("... In getVideo() ...");
        
        FacesContext context = FacesContext.getCurrentInstance();

        System.out.println("... Current Phase Id: " + context.getCurrentPhaseId());
        
        if (context.getCurrentPhaseId() == PhaseId.RENDER_RESPONSE) {
            // So, we're rendering the view. Return a stub StreamedContent so that it will generate right URL.
            return new DefaultStreamedContent();
        } else {
            // So, browser is requesting the media. Return a real StreamedContent with the media bytes.
            System.out.println("Trying to get video stream ...");
            String filename = context.getExternalContext().getRequestParameterMap().get("filename");
            String foldername = context.getExternalContext().getRequestParameterMap().get("foldername");
            InputStream stream = new FileInputStream(new File(cacheData.getLookupItemByKey(KEY_NEWS_IMG_PATH, LOOKUP_TYPE_VALUE) + foldername + "/", filename));
            return new DefaultStreamedContent(stream, "video/quicktime");
        }
    }

When I attempt to render my page, I see it hits the bean and on the 4th time it fails with the following stack:

Code: Select all

Info:   ... In getVideo() ...
Info:   ... Current Phase Id: RENDER_RESPONSE 6
Info:   ... In getVideo() ...
Info:   ... Current Phase Id: RENDER_RESPONSE 6
Info:   ... In getVideo() ...
Info:   ... Current Phase Id: RENDER_RESPONSE 6

I had the same problem trying to play an mp4 file. I followed the code with the debugger. This is statement 52 of MediaRenderer, the one that rises the exception:

if(value != null && value instanceof StreamedContent && player.getType().equals("application/pdf")) {

At run time I could see that value had a reference to my StreamedContent object and player a reference to an instance of QuickTimePlayer. This is the getType() method of QuickTimePlayer:

public String getType() {
return null;
}

No way to escape from that NPE. I guess Media component has not been properly tested.

Which PF version? Tried the latest?

lucasic · 23 Feb 2020, 02:26

Hello,

im trapped on this situation and didnt found any solution. Can someone help me?

Im using the PF 7.0.

When i pass the video from an file on resourcer, the component work fine using the quicktime player, but when i tried to use the StreamedContent, everything is going down and i received the NPE. I already tried everything, but nothing works. Can someone please help me?!

This was reported and fixed and will be in 8.0 see: https://github.com/primefaces/primefaces/issues/5586

For now if you are stuck on an older version you have to override the Renderer yourself and make the same fix as above.
