The URL above describes what I believe is a variation of my problem.
I have VOB ready MP2 files that I need to convert to AAC/MP4.
First step is to unpack the audio to WAV using ffmpeg, then run
faac -b 64 -o blat.aac blat.wav
In some cases this hangs forever, pegging CPU close to 100%.
On the other hand, if I remove '-b 64' it doesn't hang (defaults to 128 I believe).
I've experienced this on Ubuntu as well as on Gentoo, so not related
to the emerge/portage. It is a bug in the program. I'm flagging
in case the bug is fixed in a more recent version of faac that you may
want to push to stable sooner rather than later.
BTW -- THE ABOVE URL NOTES WORK AROUNDS. I'm mentioning this in case
someone else hits this bug and stumbles across this bug report looking
for a clue how to work around the problem.
Reproducible: Always
Steps to Reproduce:
1.run faac against some wav files with -b 64 option
2.
3.
Actual Results:
cpu pegged close to 100%
faac hangs
Expected Results:
faac should have proceeded with the encoding
