Hi,
macosx-10.11.6, ffmpeg-3.2.4 (via macports)
I have a strange old video that i'd like to convert.
It's strange because it's a MOV file containing
WMA2 and WMV3. I can only play it using quicktime
on one old mac. It doesn't play on a recent mac
or on windows10.
The output of ffmpeg -codecs includes:
DEA.L. aac AAC (Advanced Audio Coding) (decoders: aac
aac_fixed aac_at libfdk_aac ) (encoders: aac aac_at libfdk_aac )
DEV.LS h264 H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10
(decoders: h264 h264_vda ) (encoders: libx264 libx264rgb h264_videotoolbox )
DEA.L. wmav2 Windows Media Audio 2
D.V.L. wmv3 Windows Media Video 9
The output of ffmeg -formats includes:
E mov QuickTime / MOV
D mov,mp4,m4a,3gp,3g2,mj2 QuickTime / MOV
E mp4 MP4 (MPEG-4 Part 14)
If I try to convert it to mp4/h264/aac with:
ffmpeg -i in.mov -vcodec h264 -acodec aac out.mp4
I get:

Error opening filters!
Any idea what this is trying to tell me?
Is there something wrong with the file?
Or with the ffmpeg installation?
Or the command? Or something else?
Thanks.
