No audio when playing mp4 file with HE-AAC

Post by hottif »

Hi,

First of all I'd like to thank SubJunk for this great tool. Keep up the good work ;)

Now here's my problem:

I got downloaded some music videos from http://www.muzu.tv as mp4s. Here's one example:

Vollständiger Name : G:\Videoclips\J\Jamiroquai\Jamiroquai - Cosmic Girl.mp4

Audio
ID : 2
Format : AAC
Format/Info : Advanced Audio Codec

The file playes well on the PC. When I start to watch the video using UMS and my PS3 connected via 1GBit network I can't hear any sound. I figured out that it has to be the HE-AAC stream causing the problems since other mp4s with normal AAC audio play well. I remuxed the streams into an mkv container. Playing the mkv just worked fine. It seems to be the combination of mp4 + HE-AAC streamed using tsmuxer.

As I got many of those files it would be highly appreciated if this issue could be fixed since it would be a really big effort to remux all of those yet existing files and all future files.

Thanks in advance,
hottif
