PHP-FFMPeg is not processing files on CentOS server
22 novembre 2019, par Diego MirandaPHP-FFMPeg Version : 0.13.0
FFmpeg Version : N-95710-gb25b643
CentOS 7.7
Actual Behavior
We are using PHP-FFMPeg on laravel to process a video file to 720p and 480p.
The PHP-FFMPeg is not processing the file or generate a file with 0 bytes.
Sometimes one of this resolutions is precessed, most of the time is the 720p.
The Exception return "Encoding failed".
This occours only on production server CentOS.
Executing the command of FFmpeg on prompt of production server works well.
Expected Behavior
PHP-FFMPeg process a video file to 720p and 480p.
Code
We have two jobs of Laravel to process the files in chain.
In the ProcessVideo720PJob.php file :

What is the minimum amount of metadata is needed to stream only video using libx264 to encode at the server and libffmpeg to decode at the client ?
19 mars 2012, par cloudravenI want to stream video (no audio) from a server to a client. I will encode the video using libx264 and decode it with ffmpeg. I plan to use fixed settings (at the very least they will be known in advance by both the client and the server). I was wondering if I can avoid wrapping the compressed video in a container format (like mp4 or mkv).
Right now I am able to encode my frames using x264_encoder_encode. I get a compressed frame back, and I can do that for every frame. What extra information (if anything at all) do I need to send to the client so that ffmpeg can decode the compressed frames, and more importantly how can I obtain it with libx264. I assume I may need to generate NAL information (x264_nal_encode ?). Having an idea of what is the minimum necessary to get the video across, and how to put the pieces together would be really helpful.
