HLS Stream probs

Dev Community Dev/API Corner

I’m banging my head against a wall with this HLS stream stream. It seems like the transcoder is starting with the wrong parameters, could be a bug?



Relevant code:


<br />
@route(VIDEO_PREFIX + "/play/{type}/{id}")<br />
def PlayVideo(type, id):    <br />
    oc = ObjectContainer()<br />
    <br />
    if type == "Archive":<br />
        media = JSON.ObjectFromURL(BASE_URL + "clips/clip?sessionId=" + GetSessionId() + "&id=" + id)<br />
    elif type == "Event":<br />
        media = JSON.ObjectFromURL(BASE_URL + "events/event?sessionId=" + GetSessionId() + "&id=" + id)<br />
        <br />
    <br />
    key = media["type"] + media["id"]<br />
    <br />
    vco = VideoClipObject(<br />
                title = media["title"],<br />
                key = Callback(PlayVideo, type = type, id = id),<br />
                thumb = media["poster"],<br />
                rating_key = key )<br />
            <br />
    if "MobileH264" in media["formats"]:<br />
        vco.add(<br />
            MediaObject(<br />
                parts = [<br />
                    PartObject(<br />
                        key = HTTPLiveStreamURL(media["formats"]["MobileH264"]) ) # = http://www.mywowzaserver.com:1935/vod/mp4:15fee433-8adb-4617-bda5-3445a42b081d.mp4/playlist.m3u8<br />
                        #key = media["formats"]["MobileH264"] )<br />
                    ]<br />
                )<br />
            )<br />
            <br />
    oc.add(vco)<br />
    <br />
    return oc<br />

Any help is much appreciated!

I presume I’m creating the PartObject incorrectly, but I’m not sure what the correct way would be

3

One quick suggestion before digging deeper. Try specifying the “url=” in declaration of the key for the part:



<br />
key = HTTPLiveStreamURL(url=media["formats"]["MobileH264"])<br />


Sometimes the framework seems a little touchy about it, if that's left out. It's tripped me up a few times. If that doesn't work, can you include a segment of code to show how you build the objects that call PlayVideo() ?

Same problem when I specify 'url = ’



Here’s the code that calls PlayVideo:


<br />
@route(VIDEO_PREFIX + "/type/{type}")<br />
def TypeMenu(type):<br />
    dir = ObjectContainer(title2 = type, view_group="List")<br />
    <br />
    medias = JSON.ObjectFromURL(BASE_URL + "media/get?sessionId=" + GetSessionId() + "&Type=" + type)<br />
        <br />
    for media in medias:<br />
        if media["authorized"]:<br />
            key = media["type"] + media["id"]<br />
            vco = VideoClipObject(<br />
                        title = media["title"],<br />
                        key = Callback(PlayVideo, type = media["type"], id = media["id"]),<br />
                        thumb = media["poster"],<br />
                        rating_key = key )<br />
            dir.add(vco)<br />
            <br />
    return dir<br />

Hey! It works! After a small modification of the Lookup method signature. Thank you!

7

Coool! :) Just out of curiosity, what did you have to change in the Lookup function?
8 

<br />
def Lookup(title=title, thumb=thumb, type=type, id=id, rating_key=rating_key):<br />


to


<br />
def Lookup(title, thumb, type, id, rating_key):<br />


I'm new to Python, not sure if that "should" work or not, but it didn't on my PC

Whoops, that was a mistake on my part, sorry!
