I do have to mention that Avery Lee is wrong about AVI not supporting VBR. AVI supports constant bitrate and constant framesize with audio. This is the reason why Vorbis cannot be used (it is neither). MP3/AAC frames are fixed in size (they always decode to the same # of samples), so they CAN be used, even in VBR mode.

Avery is more referring to the Video for Windows framework, not to AVI the container itself. ACM codecs can not work for VBR, and his tool is strictly limited to using this interface for audio.

Isn't that what I've told for years? ... But OGM and MP4 zealots usually refuse to learn anything, which is the main problem.

It's actually more correct to speak about constant frame duration instead of constant frame size. I didn't even notice that you wrote frame size and not duration blink.gif

ChristianHJW: oh, really? I didn't know that.
Well, I presume he could provide support for handling VBR audio if he really wanted to anyway, VirtualDubMod and NanDub already proved it can be done. tongue.gif

And okay, I'll say frame duration from now on then alexnoe laugh.gif

There is a bug in FLAC encoding. It isn't lossless at least for transcoding from FLAC to FLAC. Decompressed WAV files aren't bit identical . The same file encoded by the mediacoder at the same setings each time smaller when it transcoded FLAC to FLAC.

I know it's old discussion but I couldn't communicate to developers neither register on their forums.
