When performing an overlay operation with ffmpeg, the video at the top becomes blurry
28 mars 2023, par LanceI have encountered a strange problem. When using ffmpeg provided in javacpp-presets to perform an overlay operation on two videos, if the video at the bottom is in motion, the video at the top becomes blurry. However, when I use locally compiled ffmpeg to execute the same command, there is no such problem. I have tried presets 5.x and 6.x, and the same problem occurs. Who can help me ?


command :


.javacpp/cache/ffmpeg-5.0-1.5.7-macosx-x86_64.jar/org/bytedeco/ffmpeg/macosx-x86_64/ffmpeg -y -f lavfi -i color=c=black:s=1920x1080 -i a.mp4 -i b.mp4 -i c.mp4 -filter_complex "[2:v][3:v]alphamerge[alphamerge0];[1:v]scale=1920x1080[out0];[0:v][out0]overlay=enable='between(t,0.0,40.141)':x=0.0:y=0.0[overlay0];[overlay0][alphamerge0]overlay=enable='between(t,0.0,40.141)':x=0.0:y=0.0[out]" -preset medium -t 00:00:40.141 -crf 20 -vcodec h264 -map "[out]" -profile:v high -force_key_frames "expr:gte(t,n_forced*8)" out.mp4

I have tried to change preset,crf,codec,profile and so on, nothing works.

FFmpeg c api create encoder for AV_CODEC_ID_H264 crash on Windows
30 avril 2023, par Guanyuming HeI'm using ffmpeg (version 5.1.2) to clip a mp4 video per frame so I need to decode and encode it. However, when I'm creating the encoder for its video stream, the program always crashes at the call to
avio_open2(), after H264 gives this error message :

[h264_mf @ 0000025C1EBC1900] could not set output type (80004005)




The configuration (time_base, pix_fmt, width, height) of the codec context of the encoder is copied from the decoder, and I checked if the pixel format is supported by finding if it's in
codec->pix_fmts.

I find that the problem does not involve all my other pieces of code, because this minimal program can duplicate the same problem :


extern "C"
{
#include <libavcodec></libavcodec>avcodec.h>
}

int main()
{
 auto codec = avcodec_find_encoder(AV_CODEC_ID_H264);
 auto codec_ctx = avcodec_alloc_context3(codec);

 codec_ctx->pix_fmt = AV_PIX_FMT_YUV420P;
 codec_ctx->width = 2560;
 codec_ctx->height = 1440;
 codec_ctx->time_base.num = 1; codec_ctx->time_base.den = 180000;

 avcodec_open2(codec_ctx, codec, NULL);

 return 0;
}


Then I suspect if it's a bug of ffmpeg. My environment is Windows 11 64-bit, Visual Studio 2022. The ffmpeg library is obtained from vcpkg, as shown in the following image :
