About wav's > 4 GB
Quote:
RiffLength = 0x7FFFFFEC DataLength = 0x7FFFFFC8 Both invalids for wav's > 2GB, but work ok with neroAacEnc -ignorelength because RiffLength - DataLength must be equal to 36 (for this kind of wav header). I check wav's > 4GB with any value in DataLength and +36 in RiffLength and always work with neroAacEnc -ignorelength, then the problem is use same value for the two fields. For BeHappy the solution is fill DataLength with 0xFFFFFEDC (0xFFFFFF00 - 36). For neroAacEnc the solution, if want support wav's > 4GB in Faad style, is ignore also the coherence between RiffLength and DataLength not only the real length. EDIT: NeroAacDec is also capable to create wav's > 4GB, send a "overflow" message but continue to write the full wav (at last with a 130 min. m4a 5.1). And fill RiffLength and DataLength with =0x00000000 (invalid for neroAacEnc). Last edited by tebasuna51; 5th May 2006 at 18:08. |

A brief back to the 2 pass issue.
Quote:
There are some possible performance improvements I can think of for now : 1. if the cli encoder manages the temporary wav, it will be 2i & 1.5o, reducing 1i. 2. if the server & encoder can handle 2 pass as an option(stdout 2 times in a session), it becomes 2i & 0.5o, no temp wav access, same effect as callback-rewind, but a bit lighter than the above 2 session method. 3. using the ram disk will result in 1i & 0.5o effect but would be subject to the short clip(music) use only, depending on the extra available ram size. 4. if the encoder decides to support 1 pass vbr/abr segment size adjustment, it would be the normal 1i & 0.5o transcoding but under the constraints of system resources(virtual memory) and encoding quality by the segment size & bit allocation algorithm.

@Ivan
How to map old vbr modes (tape/radio/internet/etc) to new Q parameter (best fit) I'm planning to write drop-in bsn.dll replacement to be able to use new Nero encoder via BeSweet

Also what about the channel order? Do ffmpeg.exe/Azid.exe realign the channelorder to 5.1 Wav specs or are these channels just passed through in their given source order? |

Hi guys!
Sorry for the question but, Can somebody provide a command line example, so I can see how it works? I have been trying: "D:\Nero\Win32\neroAacEnc.exe" -he -cbr 160000 -if "D:\Work\The Swan.wav" -of "D:\Work\The Swan.mp4" But no luck. Greetings! |

. The ABR keeps the equal bit rate per second time frame, but allocates bits variably within the frame based on the complexity. It allocates equal bits to each second. . So using the ABR for streams having variable bit rates over each second frame sounds quite confusing. . If allocating even bits(ABR) on each unit(period/segment/frame/reservoir : sample<second<file) but distributing variably depending on the complexity within is the goal, we can safely say ABR is a subset of bitrate based VBR which has both controls over size(overall) and even quality(inside). Although we are given the freedom of creative expression, if anybody wanna influence the majority reasonably with the new definitions, please update the Wikipedia.
