Quicktime show black window when I try to play an mp4 file.
The info shows the encoding as : H.264, AAC, QuickTime Text
The file plays fine with VLC. I need this file in my iTunes library so that I can stream it, hence the importance of this question.
Here is the log from ffprobe:

I have a m3u8 file which i want to use with HLS.
link to m3u8 file
My problem is that when i seek many times, the currentTime not match with the displayed frame. I experience that, the more seeking there is more difference. (it's like a constant +offset)
Our use case is very timing sensitive, we need to stop the videos at specific positions. For this we use the following code:
[_player addBoundaryTimeObserverForTimes:times
queue:dispatch_get_main_queue()
usingBlock:^{
weakSelf.player.rate = 0.0;
// The time is correct here, but the displayed frame is not sync with this time
CMTimeShow(weakSelf.player.currentTime);
}
]
I read that AVURLAssetPreferPreciseDurationAndTimingKey can help, but the currentTime still wrong.
NSDictionary<NSString *, id> *options = #{AVURLAssetPreferPreciseDurationAndTimingKey:#YES};
AVURLAsset *urlAsset = [AVURLAsset URLAssetWithURL:url options:options];
AVPlayerItem *item = [AVPlayerItem playerItemWithAsset:urlAsset];
I also read that there is a problem with the m3u8 itself. (for example wrong GOP size.)
What is the reason for the incorrect currentTime, and how can i fix this?

I'm using MediaRecorder to record video from webcam and in case of safari (or iOS Chrome) output is mp4 file. The issue is that video from iOS chrome has huge bitrate.
Using recordrtc library, this code:
this.recorder = new RecordRTCPromisesHandler(new MediaStream([
this.ownStream.getVideoTracks()[0],
this.ownStream.getAudioTracks()[0]
]), {
type: 'video',
mimeType: 'video/mp4',
recorderType: MediaStreamRecorder,
audioBitsPerSecond: 48 * 1024,
videoBitsPerSecond: 384 * 1024,
});
await this.recorder.startRecording();
creates mp4 successfully, but result bitrate of output video is 92643 kb/s for 10 FPS video!

This is only a bug in RecordRTC. Working with vanilla mediarecorder and videoBitsPerSecond works on iOS.
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:

The main video have a bitrate aprox of 15778K, and this is a signal for quality hight...
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
King Regards
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

I have an app that places videos online, and cannot find a way to get iPhones to actually play them.

The video is here
The file was created using ffmpeg from within the app.
Is this a codec problem? What shall I do to make sure iPhones can actually play them?
Oh my... amazingly, it was the file name! Even though the mime type is set, if the file name is not .mp4, the file won't be treated as a movie file!
(Which is amazing to think about, if you know Apple's history...)
