WebEx WMV to AVI or MPG

[jgq85]

I've formatted WMV to others plenty before. I usually use FormatFactory or something online like Zamzar.

However, I've recently been trying to convert a Webex recording (that's already converted from its proprietary format into WMV) into an AVI or MPG.

I've been successful with one program but it's only converting audio.
Would this be a missing codec issue?
I can play the WMV just fine and see video and audio, but once I convert the WMV to an AVI or MPG and play it, I only hear audio.

Same playback issue in Media Player (latest), VLC player, and Media Player Classic.

I searched forum here for webex but couldn't gather anything to solve.

Could you provide a sample, or a link to one.

Could you provide a sample, or a link to one.

I can try.
Do you mean like a sample WebEx file? Or the .WMV that WebEx player can convert to?

If a raw file, maybe one of these will work (searching the file types on Google):
Google "recording filetype:WRF", or "recording filetype:ARF".

Theoretically you could try converting one from there with WebEx player to WMV and see what I mean when you try to convert the WMV to anything else.

I can play the original just fine in "Media Player Classic - Home Cinema" and it shows the information of the .wmv to be:

Audio: Windows Media Audio 44100Hz mono 48kbps [Raw Audio 0]
Unknown [Raw Stream 1]
Video: G2M4 1366x768 29.97fps 83kbps [Raw Video 2]

I tried using Citrix's GoToMeeting g2mtranscoder.exe but says it ran but after a couple mins it took to complete, I see no change in the file properties or codec properties.

Playing original wmv in VLC says:
"No suitable decoder module:
"VLC does not support the audio or video format "G2M4". Unfortunately there is no way for you to fix this.""

Oh here's the answer:

1st re-encode:
g2mtranscoder.exe source=filename.wmv

for more info on g2mtranscoder, http://www.any-video-converter.com/convert-g2m3-g2m4-codec-video-to-wmv-avi-mp4-flv.php

2nd convert to avi:
ffmpeg -i "filename.wmv" -vcodec libx264 -crf !Input2! -acodec libmp3lame -ab 128k -ar 44100 -ac 2 -coder 1 -trellis 1 -flags +loop -cmp +chroma -partitions +parti4x4+parti8x8+partp8x8+partb8x8 -me_method hex -subq 6 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 2 -threads 0 Final.avi
