Im running an ffmpeg command to generate a thumbnail from a video that exists on aws s3 bucket but accessed from cloud front. So i try to stream the video in the command. This is implemented in nodejs and the ffmpeg dependency is a lambda layer. The code looks like so
const gifName = `${baseFilename}.gif`;
await execPromise(`ffmpeg -t 10 -ss 00:00:01 -i "${_url}" ${'/tmp/' + gifName}`);
_url is a clound front url. This works when i test locally even via aws SAM cli.
But this fails when testing the deployed fuction. The error output I get is as follows

Any ideas what might be wrong?
It looks like it can access the input, so that looks correct.
How long does it run for?
Does it time out?

I can't figure out how to animate the lines x1/y1 to be on the first path and x2/y2 on the second path.
Both path elements do have the same number of points
the line should arive at the keypoints at the same time, no matter the distance.
a javascript aproach (updateing the line attributes) is not what I'm looking for.
searching for e.g."svg animating line path" gave me just the drawing effect, not what I'm looking for.
with <animateMotion> and <mpath> it would be posible to animate a circle on the path but how do I use a path for start/end of a line?
I push the stream like so:

When viewed on youtube the stream audio is distorted i.e. it has regular 7ms gaps between each 32ms sound portions.
However, when I save the input stream to a file the audio is fine.
I've experimented with different input/output options for ffmpeg including transcoding the audio stream but nothing helped fix the issue. I think ffmpeg is the culprit here, since VLC or other streaming services like angelcam etc can play the rtsp stream without any distortions.
I've been trying to create a slideshow from a series of images using nodejs + fluent-ffmpeg, however it is not working well or consistently. ffmpeg occasionally emits "Error: ffmpeg exited with code 1: pipe:0: Invalid data found when processing input", and in case an eventual video (mp4) is created it seems to be missing images/frames.
The process is as follows: images are loaded into memory, transformed resized to same dimensions using lwip, written sequentially into a passthrough stream, which is fed to ffmpeg as input.
Relevant code snippets:
var lwip = require('lwip');
var ffmpeg = require('fluent-ffmpeg');
var stream = require('stream');
var imagesStream = new stream.PassThrough();
...
image.batch()
.contain(options.video.width, options.video.height, 'lanczos')
.toBuffer(options.frames.format, {quality: 100}, (err, buffer) => {
if (err) {
throw ('error convering image to buffer. ' + err);
}
imagesStream.write(buffer, 'utf8');
resolve();
});
...
ffmpeg(imagesStream)
.inputOptions('-framerate 1/' + options.frames.secsPerImage)
.input(path.join(AUDIO_ROOT, options.audio.track))
.save(path.join(path.join(OUTPUT_FOLDER, `${options.video.output.prefix}${timestamp}.${options.video.output.format}`)))
.size(`${options.video.width}x${options.video.height}`)
.on('start', () => {
console.log('creating the clip now...')
})
.on('progress', (progress) => {
var progPercent = Math.round(100 * progress.frames / (numImages * options.frames.secsPerImage * 25));
progPercent = Math.min(progPercent, 100);
console.log(`processing: ${progPercent}% done`)
})
.on('stderr', (line) => {
console.error('ffmpeg error: ' + line);
})
.on('error', (error) => {
reject('ffmpeg transcoding error: ' + error);
})
.on('end', () => {
console.log('done!');
resolve(true);
})
.run();
And here is the output:

Apparently this is a bug in fluent-ffmpeg, so I reverted to using ffmpeg directly as a child process. Here is the final code for creating an mp4 from a stream of raw in-memory jpeg images:
var timestamp = moment().format(options.video.output.timestampFormat);
var framerate = '1/' + options.frames.secsPerImage;
var videosize = `${options.video.width}x${options.video.height}`;
var audiotrack = path.join(AUDIO_ROOT, options.audio.track);
var outputFilename = path.join(path.join(OUTPUT_FOLDER,
`${options.video.output.prefix}${timestamp}.${options.video.output.format}`));
var childProcess = spawn('bin/ffmpeg.exe', ['-y', '-f', 'image2pipe',
'-s', videosize,
'-framerate', framerate,
'-pix_fmt', 'yuv420p',
'-i', '-',
'-i', audiotrack,
'-vcodec', 'mpeg4',
'-shortest',
outputFilename
]);
childProcess.stdout.on('data', data => console.log(data.toString()));
childProcess.stderr.on('data', data => console.log(data.toString()));
childProcess.on('close', code => {
console.log(`done! (${code})`);
resolve();
});
imagesStream.pipe(childProcess.stdin);
And as for the stream:
var stream = require('stream');
var imagesStream = new stream.PassThrough();
...
// repeat for every image...
imagesStream.write(buffer, 'utf8');
...
// then finally end the stream
imagesStream.end();
Continuing the journey into vnext...
I can now build the entire solution & run it successfully. However, when I try to initialise the IMvxGeoLocationWatcher, it crashes. The code & output are -
private IMvxGeoLocationWatcher _geoWatcher;
public void StartGettingLocation(Action<MvxCoordinates> response)
{
Log.Info("LocationService->StartGettingLocation");
// crashes on this line -
if (_geoWatcher == null) _geoWatcher = this.GetService<IMvxGeoLocationWatcher>();
Output -

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
Thanks for any help.
Without the inner exception it's hard to know what has gone wrong - sorry.
I'd guess that there is some problem in initializing the geowatcher - either because:
the plugin isn't registered
you call this line before you've called Cirrious.MvvmCross.Plugins.Location.PluginLoader.Instance.EnsureLoaded()
or because of some 'app specific reason'.
The tutorial app uses the location plugin in: https://github.com/slodge/MvvmCross/tree/vnext/Sample%20-%20Tutorial/Tutorial/Tutorial.UI.Touch
Does the tutorial work for you? If it does, then you'll maybe need to look at comparing the two.
If the crash persists for you, then maybe:
- post the inner exception if you can?
- or post a small repo which demos the problem - I'd certainly need more code than I can see in this 2 line snippet.
Sorry for the lack of documentation. I am making a huge effort right now to create proper documents and tutorials for the new v3 released - but this is all self-funded!
