<p class="MsoNormal">Hello Everyone,<o:p></o:p></p>
<p class="MsoNormal"> I saw this thread from 2014 and was wondering if this functionality was ever implemented. We have a similar need:<o:p></o:p></p>
<p class="MsoNormal"><a href="http://lists.live555.com/pipermail/live-devel/2014-November/018957.html">http://lists.live555.com/pipermail/live-devel/2014-November/018957.html</a><o:p></o:p></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> As some people noted, it would be possible to implement the mechanism that Michael Chapman’s asking for (rewind/seek backwards) in the client - but it<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> shouldn’t be necessary, because the RTSP protocol already has a mechanism for this - and, as Michael noted, RTSP is already used for ‘off line’
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> playback, so it makes sense to try to use the same RTSP client for both mechanisms.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> So yes, it should be possible for me to update the “MPEG2TransportStreamIndexer” application to continually extend the index file if the underlying
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> Transport Stream file keeps growing. (This will also require a small change to the RTSP server’s Transport Stream 'trick play' code to allow for the
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> possibility of the index file growing after it was first read.)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> I have only limited Internet access over the next few weeks, but I’ll see if I can make this change sometime before mid-December. (If you are
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> interested in paying money to expedite this, let me know by separate email.)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> <o:p>
</o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> Ross Finlayson<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Courier New"">> Live Networks, Inc.<o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Unfortunately, I looked through the release notes and didn’t see an entry that looked similar to this.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If it is not possible to update the tsx file as the stream is being recorded, are there strategies you have found that allow you do it?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One thing that comes to mind is to have one process save the original stream to a .ts file. Also have another process save off 1 minute chunks of the stream into smaller .ts files. Then index the 1 minute .ts files (creating small .tsx
files) and append the small .tsx files into one master .tsx file.<o:p></o:p></p>
<p class="MsoNormal">I don’t know if the format of the final .tsx file would be valid or not and I don’t know if the Live555 Media Server would pick up the updated .tsx data as it streams the video.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any help would be appreciated.<o:p></o:p></p>
<p class="MsoNormal">Thanks.<o:p></o:p></p>
