Audio encoding crash

[Selur]

Okay, so the output has audio and the problem is not that there is no audio, but that the player you use has a problem with the audio.
Totally different thing.
What player do you use for playback?

Withe VLC, that I'm using as default player, I lose sound of the small sample if I skip through it and I have no sound on the whole encoding.

I try now MPC-BE (Media player classic) and it has no problem on the small sample even jumping through it, but while it plays the whole video it report that the lenght is 1 hour and 18 minutes while VLC, without audio, reports that the video is correctely 2 hours and 27 minutes.

but while it plays the whole video it report that the lenght is 1 hour and 18 minutes while VLC, without audio, reports that the video is correctely 2 hours and 27 minutes.

Okay, seems like there is still something wrong.
Did you add any subtitle files or similar? (or have files with the same name lying next to the file?)

Ps.: when using VLC make sure to use the latest nightly build (personally I use mpc-hc).

[Devilman1]

Did you add any subtitle files or similar?

I add nothing to the file. I reencoded the DTS-HD 7.1 to Stereo AC3

have files with the same name lying next to the file?

The source file and the output file have different name.


I have the latest version of VLC.

Strange thing is that I can't reproduce this here at all. :/

[Devilman1]

Do you need the original file?

[Selur]

Nope, original is simply to large to download, not doing that.
What you can try is whether remuxing the input using mkvtoolnix before feeding it Hybrid changes anything.
also try:
1. Create 1min sample using mkvtoolnix of your source.
2. reencode that
3. check if you still have problems with the audio
4. if you also have problems with that small sample share the original sample and the reencode with me.

I segmented the whole file in 1 minutes sample and I randomly encoded some of them.

Those that I have encoded has the sound, but the lose the sound if I jump forward or backward with VLC, no issue with MPC-BE.

If I remux the avi file created by Hybrid using MPlayer with the AC3 track created during the encoding using VirtualDubMod and I remove the audio track remuxed by MPlayer I don't have any issue. I have audio in both VLC and MPC-BE, that shows also the correct lenght of the video.

Maybe is a problem of Mplayer/MEncoder.

This is the Audio according to MediaInfo in the Hybrid output:

1. Share one of those 1min samples with me that allows me to reproduce the issue and I can look at it after work.
(last time I asked you offered multiple 4GB plus samples,..)

2. Does this only happen for you with this source or also with others?

3. Since this only happens with VLC, have you asked the VLC folks about it?

I haven't asked yet to VLC folks, but VLC doesn't have audio while MPC-BE stop playing audio & video after 1h and 18 minutes the file is 2 hours and 27 minutes.

Both of themp play fine if I remux the Audio source created by Hybrid and the Video with VirtualDubMod.

2. Does this only happen for you with this source or also with others?

I didn't try on other sources because I'm not creating many avi recentrly.
I can try with another source, if it can help

All the 1 minutes that I create randomly play audio fine and the lenght is showed correctly I only have the problem of losing audio while jumping forward and backwards.
