Finding second by second bitrate of FLAC

[ndjamena]

I've been transferring my Blu Rays to my RAID6 drive with MakeMKV and converting the lossless Audio to FLAC using Eac3to to play on my WD TV Live SMP (and other future devices). It appears 16 bit FLAC plays fine 100% of the time but most 24 bit FLAC files crackle and screech throughout the movie. From the WD TV Forum I've come to believe the problem may be related to the bitrate of the files. For one thing I'm not entirely convinced of that and for another, I'd like to find what the maximum bit-rate the SMP will actually take. The only program I know of that can do something like that is MPEG Bitrate Viewer but apparently it only works on video streams. Is there a similar program for I can use on audio?

(I'm in the process of re-ripping my blu ray collection and muxing the original audio back into the file to be bit-streamed to my receiver, it solves the WD TV issue but isn't perfect for PC playback or playback on other DLNA devices)

Drop the file into mediainfo and see what it reveals.

If I mux the FLAC into it's own MKA container MediaInfo will give me the overall bitrate, but what I want is to find the peak bitrates and where they are so that I can compare them to where in the video the WD screeches at me. For my own peace of mind I need to be certain the problem is in fact the SMP being overloaded and not something like it truncating the 24 bits or some other handling error.

Maybe you could mux it in with a fake, CBR video with known bitrate (e.g. make a blank video), subtract that video bitrate from bitrate viewer

I think it provides the total bitrate A+V , not sure about other streams (like subs etc...)

EDIT: maybe I'm wrong and it's V only . I recall doing some tests and it was inaccuarte about the video only when used with a container

Foobar gives a running bitrate update of some filetypes, not sure about flac though

Yes it works with 24bit/96khz flac in foobar2k, when muxed into a mka container ; It's not a pretty graph, but it's a second by second display . There might be someway to export that data it if you ask in the foobar forum

Is there any way to output that into a timeline?

I don't know - That's what I suggest you ask in the foobar forum . A plot of time on the x-axis, bitrate on the y-axis

Even a .csv export would allow you do plot it yourself in something like excel

ffdshow has a current input bitrate for the osd (ffdshow audio), and can print out a .csv of the data - but it's not accurate for flac/mka
