Handbrake only encoding 1 chapter of 13 in a title

Description of problem or question: Handbrake only encodes 1 chapter of 13 in a title. In the GUI, I have the range defined to 1-13 in the first title. Upon encoding however, only the first chapter gets written out. I also tried switching from chapters to seconds (defining the entire title) but it ...

No way to specify a quality for the fallback audio encoder.

I wish to transcode foo.wmv and am using the following line. As you can see in try1.log, the audio in the file cannot be copied and must be transcoded. The problem is that my quality setting is being ignored and foo.mkv is generated using the default settings for vorbis of 160 kbps: HandBrakeCLI -i ...

Re: Potential bug with audio and audio-falback or user error

Thanks for the quick reply. I am attempting to create a feature request in https://trac.handbrake.fr but can't seem to locate a registration link. Is this a closed system?

According to this article, vorbis expects values from -2 to 10 whereas your scale is that divided by 1 log! Works now and thank you for the clarification!

vorbis -Q 2 is ignored and huge audio track results

As I understand it, the -Q x flag should pass x to the audioencoder. I'm using svn4375 and am finding that the -Q x switch seems to be ignored.

Re: transcode 1080p --> 480p

direct=temporal is a bad idea. For most sources, direct=spatial is better 90% of the time. Set it to spatial or auto. Unless your device only supports Main Profile, disabling 8x8dct is a bad idea (having it enabled has a fairly low speed cost, but improves compression efficiency a lot). faac is not...

Re: varying threads has no effect (--encopts threads=x)

I'm sorry; I don't follow. What's your point? Threads=6 is statistically identical to threads=64 with regard to overall encode speed. In other words, overloading threads does not seem to affect efficiency. This is counterintuitive. Here is how you read that boxplot: http://img824.imageshack.us/img8...

Linux BlueRay decryption support

I see that 0.95 of handbrake has BluRay support, but not "decryption support." For DVD, libdvdcss supplies the needed decryption libs. Is there an analogous package for BluRay decryption? How would one backup a commercial BluRay movie under Fair Use guidelines?

Re: varying threads has no effect (--encopts threads=x)

You only have 4 cores. Threads are set to 1.5 * cpu_count by default for a reason. I understand that, but I'm interesting in seeing how changing the value of 6 to a higher one will affect encode time, quality, etc. It's unclear to me what I'm doing wrong with my switch setting.
