[Encoder] WEBP videos error

[gbrn]

@DanielnetoDotCom Danny, I just noticed a problem with the encoder. In the WEBP file it puts a moving image that is completely unknown to me, which is not part of my videos. I would like to know why this happens.
I've seen this issue happening in several videos.

If this come from the encoder, check the encoder logs

@DanielnetoDotCom Danny, this blue image must be familiar to you, it seems to be a test image.
All videos that go through the encoder are coming with this image in the WEBP format.
I didn't find anything related to this WEBP image in the log, only.. webpimage not set.

I checked the log:
Missing media files:
There are several messages indicating that expected media files were not set:
spectrumimage not set, rawVideo not set, image not set, gifimage not set, webpimage not set, video not set.
Potential cause: These are expected output files from the encoding process, which for some reason were not generated. This may indicate a problem with the encoding process or configuration.

Error in video duration calculation:
There is an attempt to use the ffprobe command to calculate the video duration, but the command returned an error:
"status":"error", "msg":[] ,"return_val":1, "where":"getDuration", "cmd":"ffprobe..."
The returned duration was "EE:EE", which indicates that the time could not be calculated correctly.
Potential cause: The necessary video file may not be available or could be corrupted at the time of the ffprobe command execution.

HTTP 524 error:
"error code: 524": This indicates a timeout occurred during an HTTP request when trying to send data to https://xxxxxx.com.br/objects/aVideoEncoderNotifyIsDone.json.php.
Cause: This error code is usually associated with a request that exceeded the time limit. It could be a problem with the connection between the encoder and the remote server.

PHP warning about file not found:
"PHP Warning: unlink(/tmp/encoder_run.lock): No such file or directory".
Cause: The lock file /tmp/encoder_run.lock was not found when the PHP script tried to remove it. This may occur if the file had already been removed in a previous process or was never created correctly.

I'm having trouble accessing the encoder log. The log contains sensitive data such as pass="_user_hash_.
Also, URLs and endpoints are being exposed.
It is necessary to implement better security in the log beforehand.

error code: 524 is your issue, and this is not an error in the code, but in your webserver

so you probably have a proxy, you must find out and fix it.

I sent several parts of the encoder LOG... This is just a small error... which may even be from the server. But it does not influence the main problem of this issue. This is not the focus of the issue.

Why is this strange image being loaded in my videos?

[DanielnetoDotCom]

The image is because for some reason you could not get the images from the encoder

Check more from your encoder logs

@DanielnetoDotCom Danny, I noticed the following error in the encoder log. The image I reported is appearing when ffmpeg fails to execute libwebp:

The error message "Unknown encoder 'libwebp'" indicates that the libwebp encoder is not available on the system, resulting in failure when attempting to create the WebP image from the video.
The command used to attempt to generate the WebP image was as follows:

ffmpeg -y -ss 00:10:00 -t 3 -i '/var/www/html/AVideo-Encoder/videos/110_tmpFile.mp4' -vcodec libwebp -lossless 1 -vf fps=10,scale=640:360:force_original_aspect_ratio=decrease,pad=640:360:-1:-1:color=black -q 60 -preset default -loop 0 -an -vsync 0 '/var/www/html/AVideo-Encoder/videos/110_tmpFile.mp4.webp'

Libwebp was installed on the server, but it is not compiled into ffmpeg:

@DanielnetoDotCom Danny, I ran the tests and now it is generating the Webp image correctly.
But I can't send the videos again to the ID already created, it keeps the WEBP images and doesn't replace the wrong image. Even if I manually send the WEBP image, it is not replaced.

[DanielnetoDotCom]

Create a new video then swap them
