I get about heigh (16*68=1088) but that nvcuvid crash was the mystery. It happens only with latest versions of x265 and on 0.64 LAV (why 0.64 LAV is also not surprisingly to me because I know that HEVC decoding stuff was programmed there).

Any news on the Low-Pass Filter decision? I was watching the Interstellar blu-ray (DTS-HD MA track, newest nightly, no DLL), and their is distinct audio distortion on high-bass parts (wormhole, waves), distortion that definitely shouldn't be there (Audio switcher, only LFE ticked). As far as I know, even with the Dolby Home Theatre v4 black-box, there is no low-pass filtering in the entire audio chain. For a standard USB DAC, motherboard audio or sound card, there won't be low-pass filtering, which means distortion. Should this be done at the individual decoder level, or globally by LAV? It would keep LAV simple if the decoder was responsible for low-pass filtering, ending concerns about double-filtering. Especially considering that many of the codecs people use are filtered at the encoding stage (AC3, standard DTS), and its only a few popular codecs that need filtering (DTS-HD, TrueHD). And conveniently, one of those decoders is still in active development, the other implemented by FFmpeg (I think) which could still be patched.

Star Trek (TrueHD 5.1) also has distortion in the LFE channel.

With all the discussion and the obvious downfalls and examples of problems not having one I think it's a no-brainer, there needs to be a filter.

Possible that the player is unable to guess a playing time because it misses an average video bitrate field in a header or continuous time stamps through the whole video. Players usually don't scan the whole file before playing. Remultiplex the TS to MKV, then it should be possible to seek, because the MKV should have a keyframe index then.

Check out the AVR settings. Perhaps, its set to pass sound to TV, and since TV doesn't supports HD sound... Also check Windows sound properties for HDMI audio. Do you see HD formats there?

Could you help out a little? There was a discussion in the x265 thread about playback problems when muxing with mkvtoolnix. After some generations of muxing/demuxing LAV software playback hangs at the start, first generation crashes CUVID.
Here is a sample file:
https://mega.co.nz/#!M4k1xAKZ!ExOzB1...xACD8kuJ7-vGxg

Is this a bug in LAV or in mkvtoolnix? If it's in mkvtoolnix it would be great if you could answer in the mkvtoolnix thread

/edit:
Sorry, I still had old mkvtoolnix version installed for test. Ignore the sample.

5.1 channels problem on 7.1 system

Hi,
I think there is a problem on LAVaudio with surround output.
On 5.1 sound, the surround sound goes on the back surround output, and this is wrong !

5.1 surround sound should be on side speakers, not back.
With a 7.1 system playing 5.1 movies, it's a big problem.

On 7.1 sound, no problem, back surround is on back and side on side.

Look at this picture captured on live stream :



Thanks for the support !

When playing 6 channel PCM, DTS, AC3, etc audio files, using LAV 0.64.0.33-git, and passing the audio via HDMI to my Onkyo amp. I can confirm that the audio is correctly output to my 'side left' and 'side right' speakers, but LAV's graphic reveals that they are 'back left' and 'back right' speakers: -




Cheers

Doesn't LAV have an option for that? "convert to standard channel layout" it's called I believe.

I have the same problem with my 7.1 setup. When playing 5.1 audio I get the side's sound on the back speakers.
I work it around using MPC-HC audio switcher custom channel mapping. I select 6 channel's and then map the back speakers to the side speaker.

But yes, I would prefer that LAV Audio had it correctly, so I could disable MPC-HC's audio switcher.

Nev has already made a change to the git which I think could be for addressing the issue. Test the upcoming nightly.

Yes, it is corrected.
I've disabled the custom channel mapping and MPC-HC's audio switcher and now LAV Audio plays the 5.1 side channels on the side speakers, on my 7.1 setup.

Thanks nevcairiel!

As you talking about recorded mpeg - can split it's as binary file, use dgsplit, http://neuron2.net/dgsplit/dgsplit12.zip
