Setting either dimension to less than or equal to zero which is the default means the resolution of the first decoded video frame is used for that dimension. But that’s just guessing. If the provided track number isn’t a video track, an error is raised. Disables caching and seeking for maximum compatiblity. How do we handle problem users?

The following arguments are valid: Only intended for opening images but might work on well with some obscure video format. If fpsnum is greater than zero, this filter will force a constant frame rate, expressed ffvideospurce a rational number where fpsnum is the numerator and fpsden is the denominator.

Anyway, encodes 8 or 10bit, x with open-gop are having a hard time opening with virtual ffvideoeource, or megui’s preview thing since the new avisynth, when trying to use FFVideoSource.

Only set when no type of CFR conversion is being done rffmode and fpsnum left at their defaults. Here’s a short sample of an original encode.


No adjustment is made; the first decodable audio sample becomes the first sample in the ffvideosource. Setting either dimension to less than or equal to zero which is the default means the resolution of the first decoded video frame is used for that dimension.


What version of ffms are you using?

Used internally by FFInfo. Something like the following. FFmpeg converts it fine thought.


You should also note that setting this parameter incorrectly will cause all file openings to fail unless your filenames are exclusively 7-bit ASCII compatible. Or any way I can work around this within FFMS2, perhaps an earlier version that doesn’t have this problem? Ffvideosource not found — Looking for solution Hello Elsie, Try the following methods to work around that issue. If not, how can I get the current frame number? Track numbers start from zero, and are guaranteed to be continous i.

AviSynth:can’t get ffvideosource to work. – VideoHelp Forum

If no index is found, all video tracks will be indexed, and the indexing data will be written to cachefile afterwards. Invokes indexing of all tracks if no valid index file is found, or if the requested track isn’t present in the index. Opens files using FFmpeg and nothing else. I don’t know where exactly any differences are left over.


When using either of those modes, it will also make the output be assumed as CFR, disallow vertical scaling and disallow setting the output colorspace. Active 6 years ago. Samples are created with silence or discarded so that sample 0 in the decoded audio starts at time zero.


Only useful for testing and containers where libavformat doesn’t report keyframes properly. Results 1 to 30 of A helper function similar to Avisynth’s internal Info function; shows general information about the current frame. Note that this filter’s idea about what track has what number may be completely different from what some other ffbideosource might think.

But AVSMeter the bit application should be able to use a bit avisynth. The backtrace is as follows: Ffvdieosource FFmpeg source definition of the characters:. Find More Posts by fvisagie.
