Note that FFmpeg does not auto-detect rawaudio
input (it is not easy to detect).

This looks a little schizophrenic:
Please write: ffmpeg -f s16le (no need to
specify the codec).
Note that you cannot write yuv420p rawvideo
to mov, this is not a deficiency of FFmpeg
but the mov container (rgb24 works

I'm trying to take a raw video file and raw audio and remux them together
still as raw. I don't want any compression. I'm doing something wrong but
not sure what. It ends up making h264 even though i never asked for it. I
got this command from a tutorial on the web on how to concat multiple
videos
Thank you Moritz,
Thank uou for the "script". So, to achieve the "prgramatically" part of my
request, is there a way to write a c program ( thatlink it to ffmpefg
libav* libs) that executes that script (not in command line mode) ?
Cheers,
P

But let me try it differently:
You have an input file with a logarithmic
colour space that is not supported by FFmpeg.
If you are sure that you know what you are
doing, you can of course use FFmpeg to
compress your raw data (I believe ffv1 was
tested much better already but this is not

Hello,
Is there a recent sample that illustrates how to programmatically convert a
sequence of jpeg files and a wav file into a video file ?
I will be grateful if you can help.

That would be ASS subtitles then.

I'm attempting to create a QuickTime proxy with H.264 video and multiple
tracks of aac audio, timecode track & timecode burn-in.
My source is 29.97 fps, but the tbc is reported as 59.94 and if I do not
pass -r 29.97 before -map 0:v the output proxy is encoded at 59.94 fps.
But even though I have

Not necessarily related: Visual inspect

This is not generally true and depending on what
you mean with "rendering" it is at least very
misleading.

Please remove -r 15, I think it does not do
what you want. I would also suggest to test
without -t.
Iirc, you had to press play on your camera.
Did you do that?

This email list is for users of FFmpeg, the FFmpeg
project has nothing to do with ffmpeg-php.

I want to have a live broadcasting via HLS,
I used to do it with RTMP, but multitude of users made me to use HLS
instead.
Now the question rises here, how small should hls_time be,and how shortened
should be the hls_list_size in order to have near-live broadcasting?
Best Regards,

But I get this error:
