I've been tearing my hair out trying to do this.
I have an (interlaced) h264 stream that I've demuxed from an MKV file.
I've tried with: `vid=DirectShowSource("video.h264", audio=false)` but I just get:
I've tried the latest release of FFmpeg2Source, however that seems to just hang as soon as it tries to open seemingly any file.Code:DirectShowSource: couldn't open file video.h264 Cannot play back the file. The format is not supported.
What am I doing wrong?
FFMPEG proper gives me this:

I'm not sure if any of the source filters work with the h264 elementary stream.
Any reason not to access it from the container? -
Thanks ProWo. Could have sworn I tried this earlier. I guess sometimes what we think we know is just phantoms ...
