Fixed bug when audio had negative offset
Fixed support of video with sparse index
Btw it is interesting that if I take example "Downhill Babes...mkv" which has sparse index and copy it as mp4 with ffmpeg utility it instantly gets full index and works much smoother thanks to it. |

AFAIK mkv's don't have full indexes by default, though there is an option to write them

Added project to SourceForge, link on first message.
Added support for multiple segments.
This is intended to join files split by 2 or 4 Gb while recording. But it may be possible to join arbitrary clips as well.
"Append AVI segment" may work too, but it requires patch to VirtualDub itself.
Added support for cineform format. This will use VFW decoder, and it works for avi, mp4, mov.
With avi there is no benefit compared to internal avi driver, other than convenience (no need to select drivers).
Also source code supports decoding with cineform SDK and is about 20% faster, but it is not enabled because it requires license.
Added info about required memory and index quality.
The memory info is essential as some file can require quite a lot.
Fixed some bugs. |

Found a bug that's in both of the FFMPeg plugins
Actually it's an invalid assumption and a cause of some videos that seem to have very high fps
Some videos I've looked at have three streams, two are marked as AVMEDIA_TYPE_VIDEO and one as AVMEDIA_TYPE_AUDIO
eg
stream 0 = video
stream 1 = audio
stream 2 = video
This stream 0 is where the trouble is, as sometimes it's not actually a video but a still thumbnail image
Or, a MJPEG single frame image
If you select this stream 0 as your video stream you're stuffed as all the fps etc is wrong, seeking on it fails etc
You have to ignore that stream and use the other one
av_find_best_stream is an easy way to figure out the correct one
I'm assuming that the images are marked as AVMEDIA_TYPE_VIDEO because there isn't a AVMEDIA_TYPE_PICTURE ........

Does it also cause those Opaque data errors ?

What did you mean by Opaque data errors?
Anyway "DATA" streams have no effect on video\audio reading. Indeed I see data stream in hero4 clips. No problem. |

Every now and then we used to see Opaque data errors. Though it could of been FFMpeg or xvid was a while ago not sure if still an issue thought I would ask
I don't use xvid now cannot remember the last time I did use it mostly only encode using x264 and intermediate lossless encoders
OT: Reminds me to look at x265 again to see if they have made progress and fork builds for XP. And whether any benefit using x265 oposed to x264 |

Got it, these errors are related to direct stream manipulation.
I dont plan to mess with it any soon so I cant help, but thanks for asking 
OT: afaik cineform is excellent intermediate. Very fast and robust. I tried lagarith once and it was awfully slow (but maybe I downloaded wrong driver).
