aac+ issue #4
Comments
|
Hello [miketyson666] I got a MPEG TS already about this issue. It very much seems that this is caused by shoutcast stuff being put into the output stream but the receiver being unable to handle it correctly. If you use ts2shout on the command line you can try (please take care to set "noshout").
This should give you the plain aac without included shoutcast stuff. Shoutcast bytes are only allowed for players that support it and request it with the Icy-MetaData header in a http(s) request. The resulting aac should be playable with mplayer without error messages. Regards, |

Hi Carsten, Example #1, aac stream with no EPG or RDS (processing this stream with th2shout CGI has no problems) cat testGamma.ts | ts2shout rds > outputGamma.aac Example #2, aac stream with no EPG or RDS (processing this stream with th2shout CGI produce the errors reported in my first post) cat testaac.ts | ts2shout rds > outputTestaac.aac Here the links to the streams: As these streams don't carry any EPG or RDS information, it is not a problem play them, as we can avoid ts2shout and simply process with TVH with audio profile. Nevertheless, if the problem is related to the aac format, I suppose one day we can face the same type of streams but with EPG/RDS and ts2shout will be unable to process. I'm submitting this issue just in this perspective. bye |

Yes, it is the same case as in my above comment. Please use the option "noshout" if you convert at the command prompt and the resulting file is a valid aac file that can be played without errors with a decent version of mplayer/ffmpeg etc. cat testGamma.ts | ./ts2shout rds noshout > testGamma.aac |
Hi Carsten,
I recently noticed an issue with ts2shout with a specific aac+ stream.
It can be played on LMS with ts2shout (ffmpeg built) using your faad script based on ffmpeg (not with faad bin, even compiling faad2) but it is not stable, sometimes the play doesn't start.
I analyzed the ts2shout log and the stream using ffmpeg -i, both for the original stream and the stream encoded by ts2shout.
See below my results, and here https://www.croci.it/download/aac_latm.ts a stream sample. Maybe you are interested to check how this stream is processed by ts2shout (I suspect the issue is the aac_latm codec)
