@stephanV and meilin:
Fixed.
BTW, I was wrong about something. It looks like the older VirtualDub only used RGB 555, so there never was a converter for 565 in my MPEG code (until today).
In fact it's interesting to compare the two, because that one extra green bit makes a surprisingly big difference in the quality.
@neuron2:
I forgot to get back to you above. I don't believe it's true that all audio packets must have PTS, or at least it doesn't say that anywhere in the MPEG specs. Plus I realized that it wouldn't matter if it did, because AC-3 isn't an audio stream as defined in the spec.
I'm still thinking about an internal solution to the general audio skew problem with VOBs...

@fccHandler:
Kasumi does interpolate chroma and uses horizontally coaligned chroma samples for YCbCr, but cannot currently handle interlaced chroma positioning.

Thanks, I thought as much.
I've never done much DVD ripping; most all of the MPEG-2 I work with is interlaced, so it's rather important. Kind of like compression artifacts, once you begin to notice improperly upsampled interlaced chroma (CUE) it will haunt you forever.

hey fccHandler,
I just finished using your mpeg2 mod for the first time and it's great. Quick question/problem, I have opened up a progressive vob file in virtualdubmod and virtualdub-mpeg2 and compared the preview images side by side. I notice that virtualdub-mpeg2 assumes that my file is interlaced when it is not. Virtualdubmod seems to get it right, and all frames are displayed as progressive. Is there a reason why it is doing this? Can I disable it? Thanks again, keep up the good work. |

Stupid question: how do I use this to encode a video into MPEG format?
I've tried nothing, and I'm all out of ideas.
Thus far the process is :
1. Open the input video: use File/Open
2. Select the video compression format: use Video/Compression, pick something that looks like MPEG in the list. This step doesn't work for me. On my PC, the selection of codecs is identical in VirtualDub-MPEG2 1.6.8 is identical to VirtualDub 1.6.8 (in fact, in my ignorance, I can't see any appreciable differences)
3. Save the file: File/Save as AVI... Presumably, this step is incorrect.
Thanks in advance for any tips!

You cant save as mpeg2 with VirtualDub-MPEG2, unless you use the ympeg plugin (or maybe ffdshow vfw plugin), but that will also work with vanilla VDub. The "mpeg2" refers to the capabiloty of opening mpg files.

@fccHandler:
I've been getting a bunch of crash reports specific to the MPEG-2 version.
There seems to be a problem with the MPEG-2 decoding glue. I've attached a sample crash report below. The pointer in question (EBP) looks like a valid heap pointer so my guess it is a free memory use problem. If you saved off the link map file from the release process (you do save your link maps, right?), then you can use Asuka to get the line number:
| CODE |
asuka lookup VirtualDub.map 0x4562d9
|
or, if you have the linkmap.zip file produced by release.bat:
| CODE |
asuka lookup linkmap.zip!VirtualDub.map 0x4562d9
|

FWIW, when I see this error, it is always right at the end of processing an MPEG2 file.

I get similar crashes (free memory twice or some other null reference) encoding to XviD or DivX. Everything works great until the very end of the encoding process. Odd thing is that other codecs work okay. Crash dump attached, hope it helps:
