LAV Filters - DirectShow Media Splitter and Decoders

H264, VC1 and MPEG2 are the most common formats in modern media, covering everything from broadcasts, DVDs, Blu-rays, and a fair part of streaming too.

The 290 beta worked perfectly for me ever since it came out.
Apparently the 295 beta that was just released has some new issues, though, so stick with 290

290.36 to be more precise. 290.53 also has issues.

That is true if you're speaking about big media, but among amateurs I pretty often encounter WMV9 simple and main, probably made by something like windows movie maker.

Thank you.

I think I'm gonna go back to 290.36, as well. Re-setup my custom profiles and leave it alone until someone says there's a better driver.

Tried 0.45 and latest git version.
What am I doing wrong?

I'm trying to get a hanndle on LAV filters. I have replaced Haalli with LAV & finding some videos play without sound.
Specifically, the file below will play without sound, but, if I disable AC3 under Lav Audio formats, it plays just fine.

Am I missing something?

Thanks

Looks like i can reproduce the crash, i'll see what i can do.

Edit:
And should be fixed

what issues are you guys referring to? because I tried 295 on my 9800GTX and VMR9 becomes unstable after awhile and crashes. I reverted to 257 release drivers (which is also the last version that CUVID works right with interlaced VC-1 (havn't tested MPEG-2 or H.264)
Was this one of the known issues with 295 and 290.53?

I'm sorry to inform you that i did not document exactly what driver had what problem.
I just kept track of what driver version worked properly, and which didnt.

[Della]

Well, after not being able to play the file on two Win 7 64 machines I found the solution was to uninstall LAV & re-install Haali Media Splitter. Playback works normally.

I couldn't get the video portion to play (it would remain on a fixed position as if paused) at all with LAV, but, interestingly works fine with Haali.

Wasn't your problem with having no audio just two hours ago...?
You should decide what your problem is.

There is a known issue with WMP being "stuck" like that when there is subtitles involved. I'm working on it.

Also, i cannot reproduce a single issue here. I'm looking at WMP playing a MKV with all 3 LAV components just now.
But then, if you use WMP, i leave to your own fate, unless someone actually gives me a problem i can reproduce.

Actually I should have been more clear. The audio not working on the first machine led me to trying it on a second computer, used solely as a HTPC, with a previous version of LAV installed. On this second machine, I ran into both the audio and video issues.

I believe the problem with the audio is limited to 2 channel AAC as everything else seemed OK. I'd be happy to provide the sample, I can assure you there is a problem in the lav splitter or audio.

Thanks for taking the time to respond.

I see you edited the post, yes there are sub titles involved.

Thank you.

The video stalling issue should be fixed for the next version.
If a specific file doesn't work, a sample would be good.

isn't there something known about wrong sampling frequencies

Della try to remux it with mkvmerge, does it fix the issue ?

Thanks.
Lav splitter works well with Lagarith decoder.
LAV Video seems to be very slow (~12fps on that sample)
Lav video + internal splitter = black video.

[ryrynz]

Nev, my HTPC was not splitting M4V videos (as well as not setting the splitter with git builds) I had to set MPC's internal MP4/MOV splitter or install Haali's splitter to get it to work.

I've fixed both of those issues by using a neat program called CodecTweakTool. Even after uninstalling Haali I still had references to it and there were numerous Cyberlink references also which were cleaned out.

I can play with nightlies now! I'm a happy chappy.

I will assume 295.51 is having memory leak if I'm not wrong (eats up my ram). 290.53 works better in my machine than 290.36 (screen refresh after screen saving mode). Thanks.

I never claimed it was fast, but its Intra-only, so multi-threading it would be quite easy (and it should scale nearly linear)

Do you know if this tweak tool has been fully checked to be clean of adware and such and do they have an official webpage for it. ?

Thanks
