ffmpeg -i C.mkv -f lavfi 'movie=C.mkv[out0+subcc]' -map 0 -map 1:s D.mkv
(In practice, A.ts

Hi there.
I'm having some trouble with a ffmpeg working with an external stream as input.
This are the logs I see:
```

So your statement:
| xfade filter can not work with concat demuxer output.
was actually wrong?

A filter that "can not work with" the output of another filter, your
words, is a bug. Filters should all work together seamlessly.

Hi,
Here I have more than 10 movies and want to concatenate into a single movie
with cross-fade effect. I tried to use 'xfade' filter with many thanks to
the authors of it, but I had no luck.
What I did:
ffmpeg -f concat -i movies.txt -filter_complex
"xfade=transition=fade:duration=1"
Hi,
I have one question about h264 svc:
Does ffmpeg h264 decoder support h264 svc stream?
Thanks!

A lot of MP4 files require reading something at the end first. It cannot
work if the file is not seekable. Try to apply qt-faststart to see if it
helps.
