Confusion over codecs.

[Fleabag]

What is the difference between MP2(lav), and MP2(twolame)?

[Jan Gruuthuse]

TwoLAME is an optimized MPEG Audio Layer 2 (MP2) encoder. It is based on tooLAME by Mike Cheng, which in turn is based upon the ISO dist10 code and portions of LAME.

TwoLAME does NOT support MPEG Audio Layer 3 (MP3) encoding due to patent issues surrounding MP3.

However, as most MPEG Audio players are able to play layer 2 (MP2) files, TwoLAME makes a very good drop-in replacement for LAME and other layer 3 encoders.

7.8.4. Encoding Audio

VCD and SVCD support MPEG-1 layer II audio, using one of toolame, twolame, or libavcodec's MP2 encoder. The libavcodec MP2 is far from being as good as the other two libraries, however it should always be available to use. VCD only supports constant bitrate audio (CBR) whereas SVCD supports variable bitrate (VBR), too. Be careful when using VBR because some bad standalone players might not support it too well.

For DVD audio, libavcodec's AC-3 codec is used.

OK, that tells me what MP2(Twolame) is, but does NOTHING to explain the difference between that and MP2(lav).

Well, it does explain it indeed, if you are familiar with video encoding: quality respectively quality-size ratio is not as good.

Yes, we all know you are able to format a word in upper case, bold and underlined all together. Using only one formating would be more appropriate and convenient.

Thank you.
