I have selected high resolution video but once i run command the video resolution quality was changed and too poor quality's video i get as output video, but i don't would like to loose my video quality. let me share full command and complete log below:
Note: libx264 encoder is not supporting iOS, I'm getting failure error so i use h264_videotoolbox so i would like to get supported command with h264_videotoolbox encoder
Command:
ffmpeg -i test.MOV -loop 1 -t 5 -i 2.jpg -f lavfi -t 5 -i anullsrc
-filter_complex "[0:v]trim=0:5,drawbox=t=fill[base];[1][base]scale2ref=iw:ih:force_original_aspect_ratio=decrease:flags=spline[2nd][base2];[base2][2nd]overlay='(W-w)/2':'(H-h)/2'[padded];[padded][2:a][0:v][0:a]concat=n=2:v=1:a=1[v][a]"

Duration: 00:00:29.79, start: 0.000000, bitrate: 15778 kb/s
You have to put bitrate parameter -b:v {bitrate, in this case 15778K} in your code to keep hight qualiy, some like
ffmpeg -i test.MOV -loop 1 -t 5 -i 2.jpg -f lavfi -t 5 -i anullsrc -filter_complex "[0:v]trim=0:5,drawbox=t=fill[base];[1][base]scale2ref=iw:ih:force_original_aspect_ratio=decrease:flags=spline[2nd][base2];[base2][2nd]overlay='(W-w)/2':'(H-h)/2'[padded];[padded][2:a][0:v][0:a]concat=n=2:v=1:a=1[v][a]" -c:v h264_videotoolbox -b:v 15778K -c:a aac -map "[v]" -map "[a]" output.mp4
NOTE: if have an error with "-c:a aac" parameter, remove it, because in Apple`s OS aac is for default because is an Apple codec

I am having an issue playing MOV camera captured files from an iPhone. My FFMPEG implementation has no problem playing most file formats, this issue is exclusive only for camera captured MOV.
When trying to open the file, I can see in the logs that many requests are made, each requests decoding only one frame, before making a new request which results the video being buffered extremely slowly.
It takes roughly a minute to buffer about a few seconds of the video.
Another thing to mention is that the very same problematic file is played without an issue locally. The problem is when trying to decode while streaming.
I compiled my code on Xcode 11, iOS SDK 13, with cocoapods mobile-ffmpeg-https 4.2.
Here is a rough representation of my code, its pretty standard:
Here is how I open AVFormatContext:
AVFormatContext *context = avformat_alloc_context();
context->interrupt_callback.callback = FFMPEGFormatContextIOHandler_IO_CALLBACK;
context->interrupt_callback.opaque = (__bridge void *)(handler);
av_log_set_level(AV_LOG_TRACE);
int result = avformat_open_input(&context, [request.urlAsString UTF8String], NULL, NULL);
if (result != 0) {
if (context != NULL) {
avformat_free_context(context);
}
return nil;
}
result = avformat_find_stream_info(context, NULL);
if (result < 0) {
avformat_close_input(&context);
return nil;
}
Video decoder is opened like so, audio decoder is nearly identical
AVCodecParameters *params = context->streams[streamIndex]->codecpar;
AVCodec *codec = avcodec_find_decoder(params->codec_id);
if (codec == NULL) {
return NULL;
}
AVCodecContext *codecContext = avcodec_alloc_context3(codec);
if (codecContext == NULL) {
return NULL;
}
codecContext->thread_count = 6;
int result = avcodec_parameters_to_context(codecContext, params);
if (result < 0) {
avcodec_free_context(&codecContext);
return NULL;
}
result = avcodec_open2(codecContext, codec, NULL);
if (result < 0) {
avcodec_free_context(&codecContext);
return NULL;
}
I read the data from the server like so:
AVPacket packet;
int result = av_read_frame(formatContext, &avPacket);
if (result == 0) {
avcodec_send_packet(codecContext, &avPacket);
// .... decode ....
}
Logs after opening the decoders:
// [tls] Request is made here
// [tls] Request response headers are here

Also when calling avformat_open_input(...), 2 GET requests are made, before the returning.
Notice the "Probing mp3 score:1", that is not shown for other MOV files or any other files.
I have tried different versions of ffmpeg, I have tried messing around with the delays of the stream, I tried removing my custom interrupt callback, nothing have worked.
Code works fine with any other videos I have tested (mp4, mkv, avi).

I found a fix for this (sorta of):
Set the io_open callback of the AVFormatContext to your own function, and then when that is called, after you call the default io_open you change the buffer size.
static int (*IO_OPEN_DEFAULT)(struct AVFormatContext *s, AVIOContext **pb, const char *url, int flags, AVDictionary **options);
int IO_OPEN_OVERRIDE(struct AVFormatContext *s, AVIOContext **pb, const char *url, int flags, AVDictionary **options) {
int result = IO_OPEN_DEFAULT(s, pb, url, flags, options);
pb[0]->buffer_size = 41239179;
return result;
}
This fixes the issue. The value you set it to is usually very large (20 to 40MB). You can get that value from the second network request bytes range when you are opening the format context (first network request is made with bytes range 0-* and then the second network request is made with bytes range XXXX-* where XXXX should be the buffer size).
The reason why this fixes the issue, is because by buffering all of that data, aviocontext no longer needs to make a new network request to get the audio data. The audio data is already buffered (or at least the first position is).
There might be a better way to fix this issue, it seems like apple MOV files separate their video and audio data with these massive chunks for some reason and that causes ffmpeg to make a million network requests, for each frame.
I have an app that uploads via twitter api chunked upload, and it finally works with photos.
However, I am trying to get it to work with videos.
Uploading didnt work out-of-the-box even though the video format is mp4. The twitter guidelines for uploads are these
With that in mind, I have this ffmpeg command so far:
ffmpeg -i in.mp4 -vf \"scale=1280:720\" -b:v 5000K -minrate 5000K -maxrate 5000K -b:a 128K -r 30 -f mp4 -vcodec libx264 -profile:v high -pix_fmt yuv420p -strict -2 -ac 2 -acodec aac out.mp4
I still get "Not valid video", and I don't know why.
Here's my mediainfo output for out.mp4:

Edit: Guess Ill add my PHP code too (This is chopped in a sensible manner because the actual file is very large):
// Set up Codebird
\Codebird\Codebird::setConsumerKey($consumer_key, $consumer_secret); // static, see README
$cb = \Codebird\Codebird::getInstance();
$cb->setToken($token, $token_secret);
$cb->setTimeout(60 * 1000); // 60 second request timeout
$video = new Video($path);
// Convert to the parameter required by twitter.
$converted = $video->convert();
$path = realpath('videos/' . $converted);
$file = fopen($path, 'rb');
$size = fstat($file)['size'];
$mime_type = mime_content_type($path);
$media = $cb->media_upload([

Video is my ffmpeg class, which I'll paste below, and $path is a URL leading to a perfectly valid mp4 video.
Video.php:
<?php
class VideoConversionException extends \Exception {}
class Video {
public $name;
public $converted;
public function __construct($name) {
self::clear();
$this->name = $name;
}
public function convert() {
$tmpVideo = 'video-' . uniqid() . uniqid() . '.mp4';
$videoPath = 'videos/' . $tmpVideo;
//$ffmpeg = "ffmpeg -i https://tvcanarias.acfipress.com/BC_190907_gc_teror.mp4 -vf "scale=1280:720" -b:v 5000K -b:a 128K -r 30 -f mp4 -vcodec libx264 -acodec aac output_video.mp4";

$output = [];
exec($ffmpeg, $output, $status);
if ($status != 0) {
//die("Couldnt run ffmpeg. (Error code: #$status)");
throw new VideoConversionException("Couldn't run ffmpeg. (Error code: #$status)");
}
$this->converted = $tmpVideo;
return $tmpVideo;
}
public function shredConverted() {
// delete video.
#unlink("videos/{$this->$converted}");
}
public static function clear() {
// We can't really shred videos right away as they might be still uploading.
// Therefore, every time this library is used, we will just delete videos older
// than, say, an hour.
$files = scandir('videos');
$curtime = time();
foreach ($files as $file) {
if ($file == '.gitignore' || $file == '.' || $file == '..') {
continue;
}
$mtime = filemtime("videos/$file");
$diff = $curtime - $mtime;

I have installed ffmpeg on a microsoft/dotnet:2.2-aspnetcore-runtime docker container using
1.apt-get update
2.apt-get install ffmpeg.
seems to be installed fine, but when I try and use it as such
ffmpeg -f concat -i /data/mylist.txt -c: copy /data/output.mp4
the output is that the first video part is ok, but the second colors are all messy (hard to explain) and when I change the order of the videos in the list still the first in the list is ok and the second is messed up.
p.s same settings on a different machine works (ffmpeg for ubuntu)
bad
