excellent !

i have just build a beta of automkv that use yout ffmpegsource!

Excellent! now many users will be able to decode/process several kind of media (expecially when directshow source isn't so affidable)

just to know: is it a bug or know that framerate is always 30 ?
and ... using with autocrop plugin (that make arbitrary seek on file) will cause ffmpegsource to throw out an error (on mkv files)

thanks again, i would like to include your works in next release of AutoMKV, if you want

thanks!

BHH

Yet another new version with big changes and probably some new bugs has been released...

The autocrop bug should be fixed and the framerate set to the average for mkv files.

Would there be any interest in a simple swscaler filter? It would allow combined resizing and colorspace conversions with some combinations possible that aren't available in avisynth by default (ever wanted to point resize the chroma when going between yuy2 and yv12?)

Autocrop is working, slow but working! THANKS!

and even the framerate is fixed!

a resizer ?

imho ... no

i use your excellent plugin primary for loading file

then i use all avisynth internals/externals plugin for every other need
BUT i don't know so well avisynth so i cannot say if would be useful for some others..

one more think: one user have reported that after 50' and 14 sec the encoding is blocked.
It was feeding a 1280/640 x264+acc matroska file, using FFmpegSource 1.3

i haven't much more information, i will ask on my automkv thread

thanks again!

BHH

Hi,

About this:

Quote:
Future improvements if there's any interest:
Convert it to a c plugin (static linking, no additional dlls)
IMHO is preferable let things as is. Reason: the uderlying dll's could evolve even though the plugin remains unchanged or be discontinued.

The source is available and without changes the binary is almost guaranteed to turn obsolete and unupgradable long before the source is with just a recompile.

I can't decode ac3 audio stream embedded in avi file, is it normal ? ("codec not found")

I think you haven't compile ffmpeg dlls with liba52 support.

Did I ever claim to have compiled ffmpeg with any additional libraries?

I suggest liba52 and libfaad2 then we can decode ac3 and aac streams which are very common.

At least with libfaad2 because don't exist a good dedicated aac decoder for AviSynth, actually we need use DirectShowSource.

For ac3 (and mpa, mp2, mp3) we can use NicAudio.dll also based in liba52.
For WAVE_FORMAT_EXTENSIBLE, ogg, flac, wma, ... we can use BassAudio.dll and Bass libraries + Add-Ons. BassAudioSource can decode stereo aac/mp4 but don't work for multichannel aac.

yes but with ffmpegsource we can do that without demux the avi or mkv and it is great

Hi,
I switched to this amazing FFMpegSource for some of the video like mp4 container, I found it more reliable than DirecShowSource especially for x264 encoding.
Now I'd like to use it for a video with this specs:
container: flv, video: vp6f, audio: mp3
But it doesen't work, is it only a problem of libraries, since the latest ffplay can read it.

thanks in advance for any help

Bye

Size limit?

Is there a size limit for the input file? When I tried earlier today it wouldn't accept a 8.5GB file but a smaller segment of the same file was ok.... ?

It's probably limited to 4GB or so because of the fseek usage. It could probably be fixed for matroska but I have no idea what to do about libavformat.

What a shame, too bad it isn't an easy fix. At least now I know it won't work, thanks.

I'm not sure the limit is 4Gb, I was able to encode a 5.15 Gb video using FFMpegSource

container: mov
video: dvvideo
audio: pcm_s16be
duration: 24:18
bitrate: 30.341 kbps

Hmmm, that's odd. I'll have to try it on some more large files then. My input was a .mkv-file. I'll try the new AutoMKV as well... (and yes, the partition is NTFS )

Nope, tried a second 8GB file and I get the same error message...

FFMpegSource: Can't parse Matroska file: I/O Error: Invalid argument

I'm on Vista (32bit), maybe that's why... :-O
