Hi,
I try to insert image picture to m4b as cover of the file.
I can read picture like this:
QPixmap pixmap;
if ( avformat_find_stream_info( fmt_ctx, nullptr ) >= 0 ) {
for ( int i = 0; i < fmt_ctx->nb_streams; ++i ) {
AVStream *stream = fmt_ctx->streams[ i ];
if ( stream->disposition & AV_DISPOSITION_ATTACHED_PIC ) {
AVPacket pkt = stream->attached_pic;
pixmap = QPixmap::fromImage( QImage::fromData( ( uchar* )pkt.data, pkt.size
) );
break;
}
}
}
I change my pixmap for example.
But I can't find information how I can insert new picture in a new
AVFormatContext:
Best regards,
Vladislav Gavrilov
