I'm trying to open a raw RGB24-in-AVI file (FourCC: "DIB") in LAV Splitter. The file plays correctly using the Microsoft AVI/WAV File Source and with VLC. LAV Splitter opens it but I can't connect it to anything (apart from ffdshow video in raw mode, but it crashes when I start playback). LAV Splitter exposes the {00000000-0000-0010-8000-00AA00389B71} subtype in its output pin and nothing else, whereas Microsoft AVI/WAV File Source exposes MEDIASUBTYPE_RGB24, which seems much more appropriate. Is this normal?

I have a problem with Lav Video Decoder, with "Use Stream Aspect Ratio" option to be exact. Here are 3 sample files of x264 anamorphic encodes for you to reproduce the issue.
One of them plays at correct AR only with this option disabled, another one only with it being enabled and the last one plays correct either way. I guess that it's a bug and hope that it will be fixed :-) |

One option would be to ignore the stream AR for files in MKV, however this is not always a good solution, as you could remux live tv into MKV, which could then change AR mid stream... The other two files decode properly no matter what the option is set to. "Use.Stream.AR.Enabled&Disabled.mkv" decodes at 16:9 with a target rectangle of 640x362, and "Use.Stream.AR.Enabled.mp4" decodes at 2.35:1 with a target rectangle of 1018x432 This of course depends on what splitter you use, because if "Use Stream Aspect Ratio" is off, the AR as defined by the splitter is used instead. I tested everything with LAV Splitter, of course. Use.Stream.AR.Disabled.mkv is just a bad encode, while the other two work fine for me.

i have this problem with a handful of files, where lav splitter can't seek through them
this one was muxed with haali, but the other files were muxed with mkvmerge. I can't make a sample of it, so I'm posting the whole thing, in 2 zip pieces ( it is relatively small, lucky enough) http://www.megaupload.com/?d=TT2YF81F http://www.megaupload.com/?d=WWGJ44ZP |

1.6G is relatively small for you?
I'll see about download those later.

nev,
I have a few files here with double english audio tracks, one is marked "default" (says madvr trayicon) and is only 2.0 AAC, the other one is 5.1 AC3. Now, lav audio selects the 2.0 by default - is there a way to override this?

Nev lav Splitter is somehow crashing MPC-HC (test builds) with Mainconcepts Mpeg-2 Decoder (SDK 9 DXVA) when drag and drop loading is involved while still playing back (tested so far only the .ts parsing part) doesn't happen with MPC-HC parser (and heavy drag and dropping)
Its easy reproducible with this simple order 1. Prefer Mainconcept Mpeg-2 Decoder 2. Prefer Lav Splitter 3. Load Mpeg2 ts 4. Start Playback 5. Drag and Drop same Mpeg-2 ts Result: MPC-HC Window doesn't respond anymore and finally the program doesn't react anymore window appears. Working: 1. Prefer Mainconcept Mpeg-2 Decoder 2. Select Internal .ts Parser 3. Load Mpeg-2 ts 4. Start Playback 5. Drag and Drop same Mpeg-2 ts Result: MPC-HC cleanly closes the playing stream and opens the drag and drop one without issues

A crash is *always* the fault of the code actually crashing. No code should ever be able to crash just from some external input, or its just bad code.

Not sure what actually crashes what in the end just stops responding and its just the reaction to the task i try in different scenarios (Decoder) lav splitter is 0.39-47
tried Cyberlink DXVA as decoder it doesn't crash with MPC-HC in this task order with Lav Splitter i would say it's ultimate hard now to pinpoint who is doing it wrong on which side (MPC-HC, Lav Splitter or Mainconcept) Gonna also try non MPC-HC test builds (as they have known init and clean close issues) With the trunk MPC-HC builds the not responding (Lav Splitter + Mainconcept Mpeg2 Decoder SDK 9) doesn't happen with the Drag and Drop operation but with File->Close it shows the same symptoms as Drag and Drop in the test builds and again using the Internal Parser no problems Also still lavsplitter-freeze.mp4 is still in 0.39-47 the Internal Parser still doesn't freeze PS: tried also 0.39-50 same 2 issues that Internal parsers show no issues with, and also used another ffmpeg based splitter (av splitter 1.1.8.14 that as well doesn't show crash issues with Mainconcept and the Drag and Drop load while playing back test though it shows the same freeze issue with the mp4 and mov streams)

The MKV spec says they are not required for seeking, but they do make it a whole lot easier. It would be great to fix that in ffmpeg so that seeking without Cue points works, not sure when/if i'll have time for that, though. Edit: On second thought, it seems the Metaseek/Seekhead block is missing, which could certainly cause it to just not find the Cue data. ffmpegs matroska parser is really rather limited.

Btw AV splitter has Programm Stream support, something really lacking in Lav Splitter compared to Potplayer parser, Mpc-hc splitter and now Av Splitter as well (though it can't instantly switch needs to restart the selected stream, its more crashy than potplayers parser, and it has a ton of black screen *.ts issues that are fixed in lav splitter (first by Video Stream Parsing later without))

Of course I'm not saying that any of this is happening between LAV Splitter <-> Mainconcept Mpeg-2 Decoder. After all in these cases you're sending bitstream and there's not so much that can go wrong there (no width, height, pitch involved etc). So I would say that it's very likely that the crash is the fault of the Mainconcept Mpeg-2 Decoder. |

Hi nevcairiel, do you think it'd be possible to add audio/speaker delay settings separately for each channel to LAV Audio? It'd be of great help to us with crappy audio card drivers not giving the option. The only way I can do it now is to use ffdshow and its delay setting.

I at least validate that the renderer provides a buffer big enough for what i think should be the stride, and if it doesnt fit, i just refuse instead of crashing. Granted, this only applys to your examples - but you get the point. Quote:
Global delay is easy, per channel delay is exponentially more complicated.
