Display FFMPEG decoded frame in a GLFW window
17 juin 2020, par InfectoI am implementing the client program of a game where the server sends encoded frames of the game to the client (via UDP), while the client decodes them (via FFMPEG) and displays them in a GLFW window. 
My program has two threads :



- 

- Thread 1 : renders the content of the uint8_t* variable
dataToRender - Thread 2 : keeps obtaining frames from the server, decodes them and updates
dataToRenderaccordingly







Thread 1 does the typical rendering of a GLFW window in a while-loop. I have already tried to display some dummy frame data (a completely red frame) and it worked :



while (!glfwWindowShouldClose(window)) {
 glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
 ...

 glBindTexture(GL_TEXTURE_2D, tex_handle);
 glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, window_width, window_height, 0, GL_RGB, GL_UNSIGNED_BYTE, dataToRender);
 ...
 glfwSwapBuffers(window);
}



Thread 2 is where I am having trouble. I am unable to properly store the decoded frame into my
dataToRendervariable. On top if it, the frame data is originally in YUV format and needs to be converted to RGB. I use FFMPEG'ssws_scalefor that, which also gives me abad dst image pointerserror output in the console. Here's the code snippet responsible for that part :


size_t data_size = frameBuffer.size(); // frameBuffer is a std::vector where I accumulate the frame data chunks
 uint8_t* data = frameBuffer.data(); // convert the vector to a pointer
 picture->format = AV_PIX_FMT_RGB24;
 av_frame_get_buffer(picture, 1);
 while (data_size > 0) {
 int ret = av_parser_parse2(parser, c, &pkt->data, &pkt->size,
 data, data_size, AV_NOPTS_VALUE, AV_NOPTS_VALUE, 0);
 if (ret < 0) {
 fprintf(stderr, "Error while parsing\n");
 exit(1);
 }
 data += ret;
 data_size -= ret;

 if (pkt->size) {
 swsContext = sws_getContext(
 c->width, c->height,
 AV_PIX_FMT_YUV420P, c->width, c->height,
 AV_PIX_FMT_RGB24, SWS_BILINEAR, NULL, NULL, NULL
 );
 uint8_t* rgb24[1] = { data };
 int rgb24_stride[1] = { 3 * c->width };
 sws_scale(swsContext, rgb24, rgb24_stride, 0, c->height, picture->data, picture->linesize);

 decode(c, picture, pkt, outname);
 // TODO: copy content of picture->data[0] to "dataToRender" maybe?
 }
 }



I have already tried doing another sws_scale to copy the content to
dataToRenderand I cannot get rid of thebad dst image pointerserror. Any advice or solution to the problem would be greatly appreciated as I have been stuck for days on this.

Add logo or watermark to Converted video using ffmpeg and PHP
27 mars 2022, par Medicare AdvisorsWe are converting videos to MP4 using FFMPEG.


We did a lot of research, however we cannot figure out how to add the company logo as a logo or a water mark to the converted video


PHP code


<?php 
$uploads_dir = 'original/';
$file_name = basename($_FILES['file']['name']);
$output_name = explode('.', $file_name)[0];
$uploaded_file = $uploads_dir . $file_name;
$convert_status = ['mp4' => 0, 'webm' => 0];

if(isset($_POST['submit'])) {
 if(move_uploaded_file($_FILES['file']['tmp_name'], $uploaded_file)) {
 // Make sure to get the correct path to ffmpeg
 // Run $ where ffmpeg to get the path
 $ffmpeg = '/bin/ffmpeg';
 
 // MP4
 $video_mp4 = $output_name . '.mp4';
 exec($ffmpeg . ' -i "' . $uploaded_file . '" -vcodec h264 -acodec libfdk_aac "./converted/' . $video_mp4 . '" -y 1>convert.txt 2>&1', $output, $convert_status['mp4']);

 // Debug
 // echo '<pre>' . print_r($output, 1) . ' </pre>';

 

 // Debug
 // echo '<pre>' . print_r($output, 1) . ' </pre>';
 }
}
?>


The logo we want to add is on : https://propeview.com/wp-content/uploads/2021/08/logo-whiteb.png
