<p class=MsoNormal>Greetings everyone, <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve been experimenting with live555 again, as we need
to be able to stream MPEG2-TS files internally within our network.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I like Live555 because it supported MPEG2-TS out of the box,
with the promise of being able to produce “Trick-Play” index files.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>When I run the MPEG2TransportStreamIndexer on any of our newly
ingest HD MPEG2-TS content we see only 0 byte index files (.tsx) generated and
no trick-play support.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The file format is definitely MPEG2-TS, the video codec (as
reported by MPlayer and VLC) is “mpgv”:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>MPlayer Output:<o:p></o:p></p>
<p class=MsoNormal>TS file format detected.<o:p></o:p></p>
<p class=MsoNormal>VIDEO MPEG2(pid=308) AUDIO A52(pid=256) NO SUBS (yet)!
PROGRAM N. 2<o:p></o:p></p>
<p class=MsoNormal>VIDEO: MPEG2 1920x1080 (aspect 3)

<p class=MsoNormal>… snip …<o:p></o:p></p>
<p class=MsoNormal>VDec: using Planar YV12 as output csp (no 0)<o:p></o:p></p>
<p class=MsoNormal>Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.<o:p></o:p></p>
<p class=MsoNormal>VO: [x11] 1920x1080 => 1920x1080 Planar YV12<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>There are no errors generated by the
MPEG2TransportStreamIndexer – but nothing except an empty .tsx file is written
after a good long time grinding.<o:p></o:p></p>

<p class=MsoNormal>---<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can anyone help? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I can try and make some of these files available, but they’re
HUGE.. <o:p></o:p></p>
<p class=MsoNormal>300MB is the smallest one I have available to me at the
moment, though I could snip the tail off of one I assume without breaking the
headers.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We desperately need trick play support on these .ts files,
so any insight is greatly appreciated.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m not afraid to write code to fix this.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
