Adding chapters to MP4 files, and being identified on iOS 12 podcast app
5 avril 2019, par Craig FrancisI have an MP4 file, where I’ve added chapters via ffmpeg.
But in the iOS 12 Podcasts app, from Apple, the chapters don’t appear. This should happen, as noted by idownloadblog.com
In comparison, when using QuickLook on MacOS, the list of chapters can be seen by clicking the chapters button (in the bottom right hand side of the window).
And opening in QuickTime Player, while there isn’t a list of chapters to view, you can use the "View > Next Chapter" menu item.
So I’m assuming this is a bug in iOS... but I’m wondering if there is another way to add chapters ? or if I’ve made a mistake ?
My current process is to create a "ffmetadata" file, as noted in the ffmpeg documentation :
;FFMETADATA1
title=Example
[CHAPTER]
TIMEBASE=1/1000
START=0
END=221913
title=Chapter 1
[CHAPTER]
TIMEBASE=1/1000
START=221913
END=1169241
title=Chapter 2https://ffmpeg.org/ffmpeg-formats.html#Metadata-1
Then I’ve tried each of the following commands :
ffmpeg -i 2019-01-02.mp4 -i 2019-01-02.meta -map_metadata 1 -codec copy 2019-01-02-chapters.mp4
ffmpeg -i 2019-01-02.mp4 -i 2019-01-02.meta -map_metadata 1 2019-01-02-chapters.mp4
ffmpeg -i 2019-01-02.mp4 -i 2019-01-02.meta -map_metadata 1 2019-01-02-chapters.mp3- The first one is from the ffmpeg documentation, where
-codec copymeans the audio file is not re-encoded. - The second one takes longer, while it re-encodes the audio data.
- The third one requires re-encoding to convert it into an MP3 file (which uses ID3 tags for the chapter data).
On a slightly unrelated note, the third party app "RSSRadio" does list the chapters, but the feature added in version 4 that allows you to "skip directly to the start of the next chapter", if the next chapter starts within the next 3 minutes, does not seem to work.
- The first one is from the ffmpeg documentation, where

PHP-FFMpeg Error while opening encoder for output stream
5 janvier 2019, par Valor_I’m trying to use this PHP-FFMpeg library, but I’m keep getting errors like
Error while opening encoder for output stream #0:0This is my PHP code
private function createTeaserVideos($fullVideoPath, $databasePath, $uploadPath) {
$ffmpeg = FFMpeg::create([
'ffmpeg.binaries' => '/usr/bin/ffmpeg',
'ffprobe.binaries' => '/usr/bin/ffprobe',
'timeout' => 0,
]);
$ffmpeg->getFFMpegDriver()->listen(new \Alchemy\BinaryDriver\Listeners\DebugListener());
$ffmpeg->getFFMpegDriver()->on('debug', function ($message) {
var_dump($message);
});
// Create teaser_video_thumb
$videoNameThumb = $this->randomTimeString() . '-thumb.mp4';
$video = $ffmpeg->open($fullVideoPath);
$video
->filters()
->resize(new \FFMpeg\Coordinate\Dimension(400, 280))
->synchronize();
$video->save(new \FFMpeg\Format\Video\X264('aac', 'libx264'), $uploadPath . $videoNameThumb);
}So what I’m trying to do here. User uploads his video and I’m trying to resize it and create one smaller video for the preview. The problem that I’m keep getting it is

Streaming video .mp4 H.264 baseline not working on some videos [duplicate]

}I cannot see any difference in the videos characteristics. Both are baseline H.264.
Both videos are playing in chrome when I access them via direct links, the problem is on android versions 6, 7, 8.
There is strange thing because when I downloaded that not loading video directly and put in the android app to raw folder and played it directly everything worked perfectly.
I checked if the problem was bandwidth, so I uploaded bigger video about 12Mbs, mp4 as well H.264 Main and then streamed it to the app and it worked like a charm. So I suspect that the issue might be with recording bigger files within my android app.
To stream video I only use MediaPlayer.That is an example of the video I uploaded and later streamed :

}
Is there any chance that my hosting provider uses some kind of software that can manipulate data that is on the server?I also check manually other videos from different websites by inserting links manually in the code to check if MediaPlayer works correctly and every video was playing.
