Hi there,
I'm trying to record lots of small wav files to give to PocketSphinx for
adaptation.
My command looks like this:
ffmpeg.exe -f dshow -i audio="Microphone sur casque (2- Plant" -acodec
pcm_s16le -ac 1 -ar 16000 1.wav
I haven't tried this particular command under Linux, but usually hittin
Thanks for trying Matteo,
I'm using Cygwin on Windows 7.
I will give a try at cmd.exe.

Hi there,

Hi,
I had already compiled ffmpeg on a 32bits OS for my aarch64 machine without
too much trouble, but now that I have a 64bits OS, I'd like to compile
ffmpeg too.
The issue I have is that gcc is started with bad options (I'm not sure of
that, that's what I think I understood):
mktemp -u XX

The fact that FFMpeg does not compile without this trick of exporting an
empty CFLAGS variable on aarch64 there: https://trac.ffmpeg.org/ .
If you consider this is not a bug, that's perfec
Hi there,
this is my first message on this list, so please bear with me.
I have access to a h.264 encoder that will supply a few rtmp streams
corresponding to the various HDMI inputs it has. It is supposed to use
ffmpeg by the way (TBS2605).
Anyway... I have a Linux machine, and my goal is to:

Thanks a lot, I am now able to stream two videos at the same time with
the computer doing almost nothing.
Now, I have to replace the audio of the streams with what is coming
from the FocusRite Scarlett 2i4 2nd generation, and lots of other
things.
Best regards,
Bruno Verachten

I had other outputs for the tee, but as it was not working, I removed
them. There must be something important that I missed in that tee
format...
Please let me know.

I guess it's because of the tee. Is there any way to put them back on? It
was useful to check the streaming was going ok.

Hi List,
I have different environments (X86, ARM, Jetson Nano) on which I'd like to
use hardware encoders and decoders if available.
I guess that I won't be able to use them if they have not been built in the
ffmpeg dependencies if I install a "generic" version.
Will the configure command autodete

Simon,
there is a script there:

help you entering the right parameters to compile ffmpeg for the

but it worked for me.

Hi there,
I compiled the RockChip fork of ffmpeg because I wanted to use
hardware acceleration on one of their chips (RK3399).
For the time being, it looks like only the hardware accelerated
decoding is implemented. So I tried:
ffmpeg -benchmark -loglevel 48 -vcodec h264_rkmpp -i

Hi List,
as stated in my previous message, the rkmpp h264 encoder has not yet
been finalized, so I'm stuck for the moment.

gstreamer has the hardware encoding part, so I thought of piping the

Hi there,
First of all, sorry for being vague, I don't have ffmpeg command line
options yet, I'm just trying to know if I'm totally mistaken, or if my
idea could be implemented quite safely/easily.
I'm currently thinking of getting rid of YouTube for streaming within
the company I work for (becau
That's a very interesting subject (to me at least).
I would like to embed automatic (or human generated, depending on the
budget) subtitles to help hearing-impaired people grab most of the
talk in our conference.

so your request i
Hi there,
I'd like to extract the number of frames pushed when streaming with ffmpeg
to a RTMP server.
For the time being, I can see the number of frames in the console, and I
read that the -report option could redirect that information to a file.
I could then parse the file, and extract the frame
Hi there,
I unfortunately have to stream from behind a proxy. It works on one of my
machines thanks to redsocks. The RTMP handshake goes well, and I can stream
to twitch or youtube.
On another machine, with the same redsocks configuration, the handshake
never finishes, be it with youtube or twitch
