I am encoding a stream using the option -map 0:p:2 but
this pulls in all the audio streams which I dont want.
How do i remove a certain stream before encoding

if I use “-vcodec mpeg4 -profile 0 -level 1 -f 3gp”

What is the difference between 3gp4 and 3gp6?

I was about to suggest something similar - how about just changing the
metadata (that which ffmpeg/ffprobe reports as major_brand and
compatible_brands)? Could that solve the problem?

If somebody can confirm that the Nintendo 3DS/2DS
requires 3gp6 a patch adding an option to write
3gp6 is trivial.
Ideally, you would test if it is sufficient to
add 3gp6 to the compatible brands.

ffmpeg -i INPUT -af silenceremove=1:0.1:0:1:0.1:0 OUTPUT
It deletes only leading silence and not deletes trailing silence.

Hi,
I would like to monitor a HLS stream continuousely with ffprobe.
In the example below I only used -show_stream but later I would like to use
-show_frames as well and output it via XML.
The HLS stream was created successfully with ffmpeg before, I could play it and

-vcodec mpeg4, I get 3gp4. But if I do libx264, I can’t get MPEG-4 Visual
and Simple@L1 to come out.

I’d have to do a little research to figure out how to change the metadata.
Unless you can tell me quick. Unfortunately since I don’t have any old “dumb”

Yes, of course!
H.264 is not allowed in 3gp4.

Hello,
I've been searching for ways to create .mp4 files directly from saved raw
video data. The sources of said data can record frames in the h264, mpeg and
mjpeg formats; I end up with files that are basically raw frames of these
formats, one after the other.
Now, I've tested the command line
