Problem with ffmpeg and name change while loading on server
29 novembre 2020, par PajtimI am testing a code in php / ffmpeg it is watermark. It works very well after uploading the video but the problem is that the video should only be with an "input.mp4" name.


I have set the path where the video should be saved and the name of each video is changed
move_uploaded_file($_FILES["video"]["tmp_name"], "./" . ('input.mp4'));after it is uploaded to "input.mp4" but even this did not solve the problem.

So it only works when you upload the video from the beginning named input.mp4.


Is there an option ffmpeg to accept each name as input when uploading video with another name ?




<form action="video.php" method="post" enctype="multipart/form-data">
 <div class="form-group">
 <label>Select video</label>
 <input type="file" class="form-control" />
 </div>
 
 
 <input type="submit" class="btn btn-primary" value="submit" />
 </form>






$video = $_FILES["video"]["name"];
$image = $_FILES["image"]["name"];
move_uploaded_file($_FILES["video"]["tmp_name"], "./" . ('input.mp4'));

// then you have to resize the selected image to lower resolution
$command = "/usr/local/bin/ffmpeg -i " . $image . " -s 128x128 output.jpeg";
 
// execute that command
system($command);
 
// both input files has been selected
$command = "/usr/local/bin/ffmpeg -i " . $video . " -i output.jpeg";
 
// now apply the filter to select both files
// it must enclose in double quotes
// [0:v] means first input which is video
// [1:v] means second input which is resized image
$command .= " -filter_complex \"[0:v][1:v]";
 
// now we need to tell the position of overlay in video
$command .= " overlay=80:50\""; // closing double quotes
 
// save in a separate output file
$command .= " -c:a copy output.mp4";
 
// execute the command
system($command);

echo '<a href="http://stackoverflow.com/input.mp4" download="download">Download</a>';

FFMPEG not creating thumbnails and converting videos
10 juin 2014, par KartikAThis is what I coded after reading many blogs and about FFMPEG
$ffmpeg = "C:\\FFMPEG\\bin\\ffmpeg";
$video_file_path = $_FILES["file"]["name"];
$converted_video_path = "converted_videos/" . $video_file_path;
$image = $name .".jpg";
$imagepath="thumbnail/" . $image;
echo "<br />";
echo $video_file_path; echo "<br />";echo "<br />";
echo $converted_video_path; echo "<br />";echo "<br />";
echo $image; echo "<br />";echo "<br />";
echo $imagepath;
$size = "120x90";
$getFromSecond = 6;
$cmd_thumbnail_create = ("$ffmpeg -i C:\\xampp\\htdocs\\Media Barron\\assets\\uploaded_videos\\$video_file_path -an -ss $getFromSecond -s $size C:\\xampp\\htdocs\\Media Barron\\assets\\thumbnail\\$image");
$cmd_video_conversion = exec("$ffmpeg -i $video_file_path -qscale 4 -vcodec libx264 -f mp4 $converted_video_path.mp4");
shell_exec($cmd_thumbnail_create);
shell_exec($cmd_video_conversion);PS : I had double quotes on the addresses earlier and also tired "\uploaded_videos\video_file_path", "uploaded_videos\video_file_path", Single quotes, "\C :\xampp\htdocs\Media Barron\assets\uploaded_videos\$video_file_path\"
This is the New script I have tried recently
<?php
$ffmpeg = "C:\\FFMPEG\\bin\\ffmpeg";
$video_file_path = $_FILES["file"]["name"];
$ffmpegVideoLocation = "C:\\xampp\\htdoc\\Media Barron\\uploaded_videos\\".$video_file_path;
$converted_video_path = "C:\\xampp\\htdoc\\Media Barron\\converted_videos\\" . $video_file_path;
$image = $name .".jpg";
$imagepath="thumbnail\\" . $image;
echo "<br />";
echo $video_file_path; echo "<br />";echo "<br />";
echo $ffmpegVideoLocation; echo "<br />";echo "<br />";
echo $converted_video_path; echo "<br />";echo "<br />";
echo $image; echo "<br />";echo "<br />";
echo $imagepath;
$size = "120x90";
$getFromSecond = 6;
$cmd_thumbnail_create = ("$ffmpeg -i $ffmpegVideoLocation -an -ss $getFromSecond -s $size $converted_video_path.jpg");
$cmd_video_conversion = exec("$ffmpeg -i $ffmpegVideoLocation -qscale 4 -vcodec libx264 -f mp4 $converted_video_path.mp4");
shell_exec($cmd_video_conversion);
shell_exec($cmd_thumbnail_create);

FFmpeg(C/libav) VPX to mpeg2video stream cannot be reproduce in VLC
21 septembre 2017, par caiomcgI am currently trying to transcode a VPX(VP8/VP9) video to a mpeg2video and stream it over UDP with mpegts.
I have initialized all of the contexts and the streams and as long as I stream it to ffplay it works, if I send the stream to VLC or another player, the receiver only display the first frame and do nothing else. If I do the same thing through the command line it works flawlessly -
ffmpeg -re -i video.webm -an -f mpegts udp://127.0.0.1:8080My output context :
this->output_codec_ctx_->codec_type = AVMEDIA_TYPE_VIDEO; // Set media type
this->output_codec_ctx_->pix_fmt = AV_PIX_FMT_YUV420P; // Set stream pixel format
this->output_codec_ctx_->time_base.den = ceil(av_q2d(input_stream->r_frame_rate)); // Add the real video framerate. Eg.: 29.9
this->output_codec_ctx_->time_base.num = 1; // Numerator of the framerate. Eg.: num/29.9
this->output_codec_ctx_->width = input_stream->codecpar->width; // Video width
this->output_codec_ctx_->height = input_stream->codecpar->height; // Video height
this->output_codec_ctx_->bit_rate = 400000; // Video quality
this->output_codec_ctx_->gop_size = 12;
this->output_codec_ctx_->max_b_frames = 2;
this->output_codec_ctx_->framerate = this->input_codec_ctx_->framerate;
this->output_codec_ctx_->sample_aspect_ratio = this->input_codec_ctx_->sample_aspect_ratio;My av_dump :
