So I have had this in another thread but thought my testing would be helpful:
Test 1 softare
x264+megui+neroaac ->mp4 containers from HD content MPEG2 streams
Test 2: Nero Recode 7 (the latest) Main Profile, all options
The target AAC was "automatic VBR 0.5" to transcode the Ac3 to aac for the MP4 under MEGUI
I used 220 for the Nero encodes for audio:
Test
HDTV MPEG2 Batman and Star Wars Ep III -> MP4 4.7GB (2.5:1 compression)
FFDshow verifed in graphedit to be teh sole audio decoding source for aac. Both libraries tries (realaac and libaac) Nero (or purevideo) for video
Test #1: High Profile HQ Slow preset:
1. The graph looks great
2. Fist frame shown then freeze - no audio. This is under graphedit or WMPlayer
Demux and remux with YAMB - same
1 pass encoding Megui FAST (main profile) - FFDShow decodes in realtiem the aac to AC3 640kbit and works great
Test 2: Nero Recode: Mp4 plays FINE.
There is the same issue wtih some apple trailers.
If you use (and uninstall FFDshow) Nero Audio 6 channel ->AC3Filter Alpha (the 1.02) -> Ac3 it works for ALL MP4 files.
Hardare:
AMD X2 4400 (2.4ghz)
2GB RAM
7800GTX
Purevideo
Nero 7
FFDshow (using either AAC library)
XP SP2
I would prefer using the FFDshow audio due to all thefeatures and the 640 encoding (vs 384 of the AC3Filter)
Suggestions??
