Now I've had some time to test this issue more extensively and you're right,
the header really is there. However after encoding I'm using mkvmerge to cut
(split) the file so only the parts I want will be there in the final mkv.
This all condenses down to one problem:

All I want to do is, generate a solid color in rgb24 pixel format. Is there
any other way to achieve this?
(Other than using an input rgb24 file? I don't want to make this command

Hi,
I am having a problem with reading video files with the ffmpeg api. I am
building on a python wrapper, that someone else wrote. I noticed a bug,
but the creator could not solve the issue. So I am trying to hunt it
down by myself.
The problem is that the wrapper truncates any video I

Hello FFmpeg-users,
I am struggling to get the concat demuxer working on FFMPEG Version 4.2.4.
I am attempting to combine multiple image files into a video by using the
command:
ffmpeg -f concat -i myFile.txt output.mp4
I get an output file from the command, but the total time is much

Any luck with solving this issue?
I am facing the same problem myself.

A typical configure line to build FFmpeg for android with NDK would be
something like this:
PLATFORM=$NDK/platforms/android-8/arch-arm
PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.4.3/prebuilt/darwin-x86
./configure --target-os=linux \

Hi All,
We are having one mp4 file with h264 codec.
we want to feed this file to a video decoder but the decoder requires
elementary stream.
So we tried to extract H264 elementary string from mp4 with below ffmpeg commnd,
ffmpeg -i input.mp4 -vcodec copy -vbsf h264_mp4toannexb output.h264
Now
I rebuild ffmpeg and cleared the issues with
WARNING: library configuration mismatch
(there was indeed libav installed because of a dependency..)
After rebuilding the wrapper, the issue is exactly the same.

I had a close look through

and compared it to what the wrapper is doing. They are pretty similar,
the biggest difference I could spot so far was in
