How can I fix video processing and 500 Error - (Laravel, FFmpeg)
19 juillet 2019, par San Martín Figueroa PabloI’m setting up a new website with Laravel for uploading videos...
I have read all the possible solutions but none of them help me to solve the issue...This is my issue : When I upload a small file (<10mb) the web works fine, the video get uploaded and the video get converted, the dashboard shows the converted videos---
When I try to upload a large file, the file get uploaded, the video get converted with a green frame on it (really uggly) and the site goes to a 500 server error...
I’m using Laravel Jobs to do the conversion.
My Controller code :
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Storage;
use Symfony\Component\HttpFoundation\Response;
use Carbon;

use Illuminate\Contracts\Filesystem\Filesystem;
use App\Video;
class VideoController extends Controller
{
public function createVideo(){
return view('video.createVideo');
}
public function saveVideo(Request $request){
set_time_limit(0);
ini_set('memory_limit', '1024M');
//Validar Formulario
$validatedData = $this -> validate($request, [
'title' => 'required',
'description' => 'required',
'palabras' => 'required',
'video' => 'mimetypes:video/mp4,video/quicktime'
]);
$video = new Video();
$user = \Auth::user();
$video -> user_id = $user->id;
$video -> title = $request -> input('title');
$video -> description = $request -> input('description');
$video -> palabras = $request -> input('palabras');
$video_file = $request -> file('video');
if($video_file){
$video_path = 'original'.'_'.$video_file ->
getClientOriginalName();
Storage::disk('videos')-> put($video_path,
\File::get($video_file));
$videoUrl = storage_path('app/videos/').$video_path;
$storageUrl = storage_path('app/thumbs/');
$fileName = 'thumb'.'_'.time().'.jpg';
$second = 2;
VideoThumbnail::createThumbnail($videoUrl, $storageUrl,
$fileName, $second, $width = 640, $height = 480);
$video -> preview = $fileName;
$video -> video_path = $video_path;
}
$video -> save();
ConvertVideoForPreview::dispatch($video);
return redirect() -> route('home')
-> with (array(
'message' => 'El video se ha enviado con exito'));
}
public function getImage($filename){
$file = Storage::disk('thumbs') -> get($filename);
return new Response($file, 200);
}
public function getVideo($filename){
$file = Storage::disk('converted_videos') ->
get($filename);
return new Response($file, 200);
}
}This is my ConvertVideo Job :
<?php

public $video;
public function __construct(Video $video)
{
$this -> video = $video;
}
public function handle()
{
$converted_name= 'preview'.'-'.$this -> video ->
video_path.'.mp4';
FFMpeg::open('videos/'.$this -> video -> video_path)
-> export()
-> inFormat(new \FFMpeg\Format\Video\X264)
-> save('converted_videos/'.$converted_name);
$this -> video -> update([
'video_preview' => $converted_name,
'processed' => true
]);
}
}One of my goals is to upload large video files (<=4GB), show a uploading process bar and a encoding process bar during the video upload.
I getting this error :

ffmpeg generate thumbnails on GPU
22 juin 2018, par Oleksandr KyrpaI try to generate thumbnails with acceleration on GPU, so compile ffmpeg 3.4.1 and run command :
./ffmpeg -i ~/Videos/1080.mp4 -vf "hwupload_cuda,thumbnail_cuda=100,scale_cuda=107:60,hwdownload,format=yuv420p" -vframes 1 -y ~/Videos/thumbs/thumb%03d.jpgBut I get wrong output picture (the color of thumbnail is green) :
Correct image must be black.
How to make first image with correct color ?

Encoding images to h264 and rtp output : SDP file without sprop-parameter-sets does not play
14 septembre 2021, par oarfishtl ;dr : I try to encode acquired camera frames to h264, send via RTP
and play this back on another device. SDP file generated by ffmpeg for
a sample video has info which my own SDP file misses. My SDP file
plays in ffplay, but not VLC, while both play ffmpeg's SDP file. I am
suspecting missing sprop-parameter-sets in my SDP file.


Ultimately I want to play this back in VLC.



I am writing code that encodes images to h264 and outputs to an RTP
server (or client ? anyway the part that is listening). I generate an
SDP file for this.


- 

- ffplay plays the stream without problem
- mplayer shows a green box embedded in a larger black box, but I read
somewhere it only supports mpegts over RTP, so not sure
- VLC does not play the SDP file.








Now when instead I use some random video and have ffmpeg output an SDP
file like so


ffmpeg -re -i some.mp4 -an -c:v copy -f rtp -sdp_file
video.sdp "rtp://127.0.0.1:5004"


I can see that the generated SDP file – which plays in both ffplay and
VLC – includes the base64 encoded
sprop-parameter-setsfield, and
removing this causes the stream to not play.

> cat video.sdp
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 127.0.0.1
t=0 0
a=tool:libavformat 58.76.100
m=video 5004 RTP/AVP 96
b=AS:1034
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1;
sprop-parameter-sets=Z2QANKzZQDAA7fiMBagICAoAAAMAAgAAAwDwHjBjLA==,aOvjyyLA;
profile-level-id=640034


My own SDP file on the other hand, does not contain this information,
and VLC hangs for 10s and then stops trying with "no data received".


> cat test.sdp
v=0
o=- 0 0 IN IP4 127.0.0.1
s=No Name
c=IN IP4 127.0.0.1
t=0 0
a=tool:libavformat 58.76.100
m=video 44499 RTP/AVP 96
b=AS:2000
a=rtpmap:96 H264/90000
a=fmtp:96 packetization-mode=1


So my theory is that my custom code must somehow add this SPS
information to the SDP file. But despite hours of searching, I could
not find a structured way to set the extradata field on the
AVStream's
AVCodecParams. The code I'm using is roughly this (I'm sure there's
unrelated errors in there) :

// variables
std::vector imgbuf;
AVFormatContext *ofmt_ctx = nullptr;
AVCodec *out_codec = nullptr;
AVStream *out_stream = nullptr;
AVCodecContext *out_codec_ctx = nullptr;
SwsContext *swsctx = nullptr;
cv::Mat canvas_;
unsigned int height_;
unsigned int width_;
unsigned int fps_;
AVFrame *frame_ = nullptr;

AVOutputFormat *format = av_guess_format("rtp", nullptr, nullptr);
const auto url = std::string("rtp://127.0.0.1:5001");
avformat_alloc_output_context2(ofmt_ctx, format, format->name, url.c_str());

out_codec = avcodec_find_encoder(AV_CODEC_ID_H264);
stream = avformat_new_stream(ofmt_ctx, out_codec);
out_codec_ctx = avcodec_alloc_context3(out_codec);

// then, for each incoming image:
while (receive_image) {
 static bool first_time = true;
 if (first_time) {
 // discover necessary params such as image dimensions from the first
 // received image
 first_time = false;
 height_ = image.rows;
 width_ = image.cols;

 codec_ctx->codec_tag = 0;
 codec_ctx->bit_rate = 2e6;
 // does nothing, unfortunately
 codec_ctx->thread_count = 1;
 codec_ctx->codec_id = AV_CODEC_ID_H264;
 codec_ctx->codec_type = AVMEDIA_TYPE_VIDEO;
 codec_ctx->width = width_;
 codec_ctx->height = height_;
 codec_ctx->gop_size = 6;
 codec_ctx->pix_fmt = AV_PIX_FMT_YUV420P;
 codec_ctx->framerate = fps_;
 codec_ctx->time_base = av_inv_q(fps_);

 avcodec_parameters_from_context(stream, out_codec_ctx);

 // this stuff is empty: is that the problem?
 stream->codecpar->extradata = codec_ctx->extradata;
 stream->codecpar->extradata_size = codec_ctx->extradata_size;

 AVDictionary *codec_options = nullptr;
 av_dict_set(&codec_options, "profile", "high", 0);
 av_dict_set(&codec_options, "preset", "ultrafast", 0);
 av_dict_set(&codec_options, "tune", "zerolatency", 0);

 // open video encoder
 avcodec_open2(codec_ctx, codec, &codec_options);

 stream->time_base.num = 1;
 stream->time_base.den = fps_;
 avio_open(&(ofmt_ctx->pb), ofmt_ctx->filename, AVIO_FLAG_WRITE);

 /* Write a file for VLC */
 char buf[200000];
 AVFormatContext *ac[] = {ofmt_ctx};
 av_sdp_create(ac, 1, buf, 20000);
 printf("sdp:\n%s\n", buf);
 FILE *fsdp = fopen("test.sdp", "w");
 fprintf(fsdp, "%s", buf);
 fclose(fsdp);

 swsctx = sws_getContext(width_, height_, AV_PIX_FMT_BGR24, width_, height_,
 out_codec_ctx->pix_fmt, SWS_BICUBIC, nullptr,
 nullptr, nullptr);
 }

 if (!frame_) {
 frame_ = av_frame_alloc();

 std::uint8_t *framebuf = new uint8_t[av_image_get_buffer_size(
 codec_ctx->pix_fmt, width_, height_, 1)];
 av_image_fill_arrays(frame_->data, frame_->linesize, framebuf,
 codec_ctx->pix_fmt, width, height, 1);
 frame_->width = width_;
 frame_->height = height_;
 frame_->format = static_cast<int>(codec_ctx->pix_fmt);
 success = avformat_write_header(ofmt_ctx, nullptr);
 }
 if (imgbuf.empty()) {
 imgbuf.resize(height_ * width_ * 3 + 16);
 canvas_ = cv::Mat(height_, width_, CV_8UC3, imgbuf.data(), width_ * 3);
 } else {
 image.copyTo(canvas_);
 }

 const int stride[] = {static_cast<int>(image.step[0])};

 sws_scale(swsctx, &canvas_.data, stride, 0, canvas_.rows, frame_->data,
 frame_->linesize);
 frame_->pts += av_rescale_q(1, out_codec_ctx->time_base, stream->time_base);

 AVPacket pkt = {0};
 avcodec_send_frame(out_codec_ctx, frame_);
 avcodec_receive_packet(out_codec_ctx, &pkt);
 av_interleaved_write_frame(ofmt_ctx, &pkt);
}
</int></int>

Can anyone offer some advice here ?

Update


When setting


this->out_codec_ctx->flags |=AV_CODEC_FLAG_GLOBAL_HEADER;


extradata is actually present in the codec context, but I had to move
avcodec_parameters_from_context()afteravcodec_open2(), as the extradata is empty before opening the codec. I now getsprop-parameter-setsin the SDP file, but VLC still does not play it.
