RunTimeError during analysis of hls .ts chunk #2

/mpeg2ts.rb:207:in `processAdaptationField': not supported adaptation field (RuntimeError)

I'm running on OSX 10.9.5 and trying to analyze a .ts file from an instance of wowza 4.1.x.

$ ruby -v ruby 2.0.0p481 (2014-05-08 revision 45883) [universal.x86_64-darwin13]

The rest of the output looks sane as it seems to be describing the details of the PES and related fields successfully.

Hi,

Thanks for the feedback. So as I understand, it gives error but keeps working and actually performs the analysis, is that what you mean?

Thank you.

No, it appears to fail after it scrapes the initial container metadata.

$ ruby ~/mpeg2ts.rb media_w1762149747_140113.ts "Elementary Stream Description {" " PID=258" " TYPE=21" " TYPE_DESC=Metadata carried in PES packets" " DESC=[38, 13, 255, 255, 73, 68, 51, 32, 255, 73, 68, 51, 32, 0, 15]" "}" "Elementary Stream Description {" " PID=256" " TYPE=27" " TYPE_DESC=AVC video stream as defined in ITU-T Rec.

Got it. Can you also send media_w1762149747_140113.ts or similar file so we could reproduce the issue?

If you need the playlist as well, I can provide that. In the interim, here is the .ts chunk.

I'm sorry, I don't see chunks attached to this ticket.

msmithng commented 8 years ago

My apologies... I guess the attachment didn't work last time. Since gh doesn't allow uploading zip files, I've dumped a set of chunks onto dropbox. The *_ao.m3u8 and related files are supposedly audio only. For this conversation, I wouldn't worry about those as I'm only trying to test the playlist.m3u8 at the moment.
