I have been trying to convert a bunch of mkv files to mp4 using ffmpeg in batch
mode via a .bat file but I can't get it right.
I've followed a number of suggested commands from various hits I've got on
google but none of them work.
Ok. Thank you Moritz.

To take up your example:
$ dd if=inputfile.ext bs=1M skip=4 of=outputfile.ext
But if you're doing this with a video file, the result can be
Hi.
If you are only changing the container and don't want to transcode the
contents, be sure to add -c copy in the ffmpeg line of the example (haven't
tested it but it seems fine), so it looks like this:
ffmpeg -i %IN% -y -c copy %OUT%

Thank you for that. It worked perfectly. And thank you for the book - it looks
like there's realms of good stuff in it.
Looks like a text book to me.. probably won't be able to read it but will have
to dip in and out of it to find things when I need them.
Congratulations on it... wish I'd

Michael, you could use this:
%~ni <- this means the filename without the extension, so instead of
renaming, just use:
ffmpeg -i %1 -y %~n1
or
ffmpeg -i %1 -y -c copy %~n1

Silly me, it's the other way around (mkv to mp4)...
ffmpeg -i %1 -y %~n1.mp4
or
ffmpeg -i %1 -y -c copy %~n1.mp4

Personally I tend to do this sort of thing with JScript on Windows. It's not
the loveliest interpreter, but then at least you have something approaching a
real programming language to do all your string manipulation!

Hello,
Any suggestion will be a great help for the below detailed problem:
I am using ffmpeg to record an ip camera stream.
The camera produces variable frame rate stream.
I am using an SDP file to capture the stream, and save it in files
containing data of of 5 mins.
OS used is centOS 6.6
Hi,
As I know, flv supports amf metadata, while mpegts supports id3 timed metadata.
How can I convert amf timed metadata into id3 timed metadata? And how to
convert id3 timed metadata into amf timed metadata?
Thanks!

Andrew

Ok thanks, I didn't realize that was coming from the camera.

In which players does seeking not work? In all
set OUT=%IN:mkv=mp4%
please note that this renaming will give unexpected results if "mkv" is
also part of the filename, for example
aamkv.mkv will be renamed to
aamp4.mp4
If someone knows a solution to this problem, please let us know.

Hello,
Simple question. I've found out that ffserver is no longer maintained. As
far as the project goes, tentatively need these requirements.
1. streaming 2 video cameras simultaneously - both of which are usb cameras.
2. 1280x720 30fps video
3. Able to be run on Pi4 with 2GB of memory.

Are you talking about timed id3 metadata?

Additional information --
I learned to use pkg-config --list-all note the results below ffnvcodec was
found.
using MSYS2 mingw 64-bit I generated the following:
$ cd /d/dev/cpp
$ PREFIX="ffmpeg"
$ PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
$ pkg-config --list-all
...
ffnvcodec
Tried the pkg-config before and after the configure. The pkg-config found
ffnvcodec both before and after however it still is reported as not found in
the configure process.
$ cd /d/dev/cpp
$ PREFIX="ffmpeg"
$ PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
$ pkg-config --list-all
...
ffnvcodec

That fixed the error you found but not the error I reported. Thanks for
solving a problem I had not yet identified.

Hello there,
Has A53 Closed Captions support been implemented in the hevc_nvenc
encoder, at the present?
I see a -a53cc option emitted by ffmpeg -h encoder=h264_nvenc but
omitted in hevc_nvenc.
Warm regards,
Dennis.
