Hello,
For few months, I have an issue when I record sound on my Linux fedora
22 desktop. I never got the fix but now I need it to be fixed, so here I am:
Hardware and software:
Motherboard ASRock 970 Extreme4
CPU AMD FX-8120 Eight-Core Processor
Fedora 22

Great improvement...
I had a look on the other thread "Converting a cassette audio tape" and
I had the idea to try to use pulseaudio. I never did.
So I installed pulseaudio-libs-devel x86_64 then compile again with
$ ./configure --enable-libpulse then $ ./make ffmpeg
Then
./ffmpeg -devices

Now the only issue I get is a lot of

Hi
From an interlaced input (video tape) is it possible to capture
interlaced video file encoded with FFV1 (using -flags +ilme+ildct)?
I can't find an answer after long search.
All my captures seem to be converted to progressive.
Thanks

I found this thread interesting
https://ffmpeg.org/pipermail/ffmpeg-user/2013-May/015470.html
It seems to no have an interlaced mode with FFV1 (at least in 2013)
Carl, could you confirm it?

Attention to Carl Eugen
and other experts,
I did lot of tests and answered your last question.
I didn't get any feedback so far, maybe you missed them.
I need to go further in my project but I don't know what to do now to
avoid the errors.
Thank you to have a look and advice.

I had a closer look on what I did previously.
With FFV1, option -flags +ilme+ildct do nothing. Debug see it but do nothing
=> I'll remove it
Moreover, documentation says:
Apply interlaced motion estimation, Use interlaced DCT (MPEG-2 and
MPEG-4 only)
With x264, debug returns a warning:
