FFMpegSource2 does not use Haali Media Splitter

[wateshadon]

Hello.

All I try to do is to use following script for avisynth on my Windows XP SP3:

FFMpegSource2("00004.mkv", overwrite=true, atrack=-1)
Trim(900,1000) + Trim(800,900) + Trim(700,800) + Trim(600,700)

FFMpegSource2 performance is much better than DirectShowSource (that is why I want to use it) but it looks like frames are in wrong order, something like 1,2,3,5,6,4,7,8,9,11,12,10,13. I suspect that FFMpegSource2 does not use Haali Media Splitter, but his internal worse one. I suspect that because Haali Media Splitter try icon does not appear.

Do anyone knows what conditions must be fulfiled so that FFMpegSource2 use Haali Media Splitter?

Marcin

If you want frame accurate access use this

LoadPlugin("C:\Program Files (x86)\Haali\MatroskaSplitter\avss.dll")
DSS2("00004.mkv")
Trim(900,1000) + Trim(800,900) + Trim(700,800) + Trim(600,700)

Tak apropo to powinno być "Does .... know ..."
"but his internal worse one" też nie gramatycznie
acha tacka to tray nie try (próbować)

Atak_Snajpera, thanks for your answer and correcting my english.

Unfortunately I cannot use DSS2() because I need to trim not only video but also audio. That's why I chose FFMpegSource2.

vid=dss2("00004.mkv")
aud=ffaudiosource("00004.mkv")
audiodub(vid,aud)
Trim(900,1000) ++ Trim(800,900) ++ Trim(700,800) ++ Trim(600,700)

you could also use nicac3source instead of ffaudiosource, but you'd have to demux the ac3 track

also, I would use aligned splice (++) , instead of unaligned splice (+)

[wateshadon]

Thanks poisondeathray. I will go with dss2() and nicac3source().

Really wants to evaluate FFmpegsource2() as opposed to Directshowsource() on my video files taken from a Canon HF video CAM. The source is interlaced 1080i. I've installed AviSynth, Haali Splitter and ffdshow. Using Directshowsource(), I am able to play the video and the info shows that it is 29.97fps interlaced.

However, when I change to FFmpegSource2("00003.mts"), it becomes 59.98fps and the sequence of the frames seems to be wrong - something like what wateshadon experienced. Anyone knows what's going on? How to use FFmpegSource2() on MTS source?

[poisondeathray]

ffms2 is unreliable for many types transport streams. Many bug reports have been filed, no ETA on fix date

[EnthusDV]

Thanks poisondeathray. Looks like I got to see if there is a need to file this one too.

I also have Canon cam (Legria HF 306 PAL). I gave up with FFMpegSource2. I use DDS2() from avss.dll (Haali Media Splitter). I found that it work best with files in mkv container. I extract audio and load it separatelly in avisynth because DDS2() doesn't load audio.

Here how I work with my footages.

1. Convert all MTS footages in folder to MKV with following batch script. Mplayer and mkvmerge and GNU grep are in %PATH%.

SETLOCAL EnableDelayedExpansion

@echo off

for %%X in (*.MTS) do (
  echo ---=== Processing %%X ===---
  
  mplayer -dumpaudio -dumpfile %%~nX.ac3 %%X | grep -c "Core dumped ;)"
  IF ERRORLEVEL 1 GOTO :error
  
  mplayer -dumpvideo -dumpfile %%~nX.h264 %%X | grep -c "Core dumped ;)"
  IF ERRORLEVEL 1 GOTO :error

  SET t=%%~tX
  mkvmerge -o "%%~nX !t:~0,10!.mkv" --default-duration 0:50fps %%~nX.h264 %%~nX.ac3
  IF ERRORLEVEL 1 GOTO :error
  
  del %%~nX.h264
  del %%~nX.ac3
  rem del %%X
)

echo SUCCESS.
goto :end
:error
echo FAIL.
:end

Note that '--default-duration 0:50fps' is for PAL cam version, you need to change it for NTSC version.

2. Open audio from mkv file with a audacity. Normalize. Remove noise. Save to flac to the same folder and name like mkv file.

3. Load video and audio in avisynth with following function:

function MkvSource(string source) {
  video = DSS2(source)
  audio = BassAudioSource(LeftStr(source, StrLen(source) - 4) + ".flac")
  return AudioDub(video, audio)
}

Hope this helps.

Thanks again.
Eventually, I used Handbrake to convert my 1080i video to 720p:

HandBrakeCLI.exe -i 00273.MTS -o 00273.mkv -f mkv -e x264 -q 0.6 -E faac -B 128 -6 stereo -w 1280 -l 720 --denoise=strong
