Summary | 0000703: dialog normalization in AC3 tracks not fully detected | ||||
Description | In the report generated by BDInfo, both audio tracks have dialog normalization. But as you can see in the eac3to log, only DN in track 4 was successfully detected and removed. It must be a bug for eac3to to get one and miss the other. I only find the issue in this particular BD source 'The Falls-2012-LKMJ'.

Every AC3 stream has a dialnorm field, which can have a value between -1db and -31db. A value of -31db is "off". So eac3to is correct here. BDInfo just doesn't understand that -31db means "off". |

Thank you for the explanation. And thank you for making wonderful tools like eac3to and madVR. |
