Nero AC3 PlugIn !?
Reply #23 – 2003-08-03 14:45:44
ok here a small summarized bug report i just sent to mausau, if someone is interested or knows solutions as i dont know if all of the bugs are caused by the ac3 plugin or nero itself: 1) when using ac3 decoder to transcode from ac3 -> he-aac nero just quits (some failure in aacenc.dll)! surprisingly ac3 -> lc-aac transcoding works without a problem! but it happens only if you hit 'Settings' and 'OK' and even if you don't even change anything it will crash, if you hit 'Cancel' it won't crash. And this only happens if HE AAC is selected, with LC AAC it works fine and it doesn't matter how much you mess with the settings, it will never crash. hm, i just saw that this he-aac bug seems to be resolved with the .30 version, but only for 2channel input, it doesnt work with multichannel input... 2) when using the ac3 plugin (version .30) in NeroMIX it starts but never finishes! when using the plugin in normal nero it finishes but the file length is a little bit longer (let's say the source ac3 is 1:00 than the output file will be 1:10 (in the last 10 seconds there is no sound, just silence) - seems like normal nero is smart enough to check that there is a failure and interrupts decoding whereas neromix still continues...) in ac3 plugin version .29 neromix also just continued as described above, but normal nero outputted a file with the right length - 1:00 3) i tested a 5.1 ac3 file and wanted to downmix it to stereo, so i used the following options: 2 front, 0 rear output channel sequence: ch_l and ch_r (btw. i hope these settings are the right ones for downmixing?) ok, with these settings i saw that the last part (half a second or so) of the ac3 isnt getting decoded by the ac3 plugin in normal nero (try ac3 -> wav with azid.exe and in nero with your plugin and compare the ends) i could also verify that the cutted end only occurs if ch_l and ch_r are chosen under "output channel sequence" (if all 6 channels are chosen (even if the 5.1 ac3 is decoded to 2 channels, the failure doesnt occur) this doesnt happen in neromix (there it decodes the end correctly but doesnt stop as described above) this happens with both .29 and .30
