Bug in transcoding video with speex audio which may impact 1.5 speex support

[Former user]

I determined the need for speedx support because Serviio was transcoding the streams with -an which is the correct result for unsupported audio codecs.

I have now found a stream containing speedx which Serviio transcodes to mp3 with -map 0:2 which causes it to fail. This is obviously a bug, which may impact your speedx solution in 1.5

Interestingly this only occurs with a web resource with the Content container: ContentURLContainer [fileType=VIDEO, contentUrl=rtmp://pub1.usa.battlecam.com/battlecam/ playpath=bc_1 swfUrl=http://www.battlecam.com/application/themes/base/flash/broadcast/VideoChatECCDN_debug.swf pageUrl=https://www.filmon.com/ live=1, thumbnailUrl=http://static.filmon.com/couch/channels/324/big_logo.png, expiresImmediately=true, cacheKey=Filmon_324_480, live=true, ]

However the live-stream using this same url issues the correct transcode command. Go figure!

The second part of this report is incorrect. This stream with speex audio fails both as a live-stream and when included in a web resource. The correct transcode above was issued by my wrapper which fixes the bug in the interim.

So is this open or resolved?

After testing, I am unable to recreate the map 0:2 command. I will retest after speex support is implemented. Lets close it for now.
