Hi, I've implemented support for the new Opus codec [1]. Opus got very positive response even by people, who hardly write something good about software [2]. Support in gmerlin is not completely sample accurate yet, I'll fix this as soon as possible. Decoding is in gmerlin-avdecoder, encoding is in gmerlin-encoders.
For the music side, my enthusiasm is however quite limited because Opus has no way to natively encode signals sampled at 44.1 kHz. The recommended way is to upsample to 48 kHz (increasing the uncompressed bitrate by 8.8 %) before encoding. Limiting the samplerates is in principle nothing wrong, many codecs have such limits. But omitting 44.1 kHz and calling this *one* audio codec for *every* purpose is a bit silly in my opinion. Let's see how this will develop. At least support in Webbrowsers will probably be quite universal since both Mozilla and Microsoft (via Skype) are involved in the development.
