I want to download a video from eventive but the tag contains a blob url (blob:https://watch.eventive.org/**************).
I have been reading some answers to similar questions but they all assume that the video has a mp3u8 file extension, which in my case doesn't.
I have also tried to directly download that url (removing the blob:) with curl, but I obtained a html code which I cant really understand, which contains a lot of references to javascript files.
Any tip would be really helpful.
Edit:
I have been doing some more tests and I have been able to found a url to a manifest file which points apparently to the video data. I have tried to open that url using VLC and it loads some info about the video, and it even plays it, but the screen is completely black.
I have also tried to download it using ffmpeg but it gives a bunch of errors.
ffmpeg -i https://eventiveprod-usea.streaming.media.azure.net/02968382-069a-4f02-ab3b-67c0b5a8d5b7/5f427f2d65a569006ebd326c.ism/manifest\(format\=mpd-time-csf\) output.mp4

I’m a complete noob trying to learn/play with StyleGAN.
I’m using StyleGAN to train a model with an image set that I built, but the output image quality is poor. The training stops after 10 ticks.
How can I change the default parameters in the code to continue training past 10 ticks?
Do I need to change the kimg or fid50k settings? Are the settings in this block of the train.py file? or the metrics file?

I can post the complete train.py file if required but it is standard version available on git.

I need to compute the frame differences between a source video and a compressed one.
For now I'm using OpenCV with Java, by extracting each frame and doing a simple difference, but it's quite slow (working a 0.5 fps, meaning that a 500 frames video will take more than 15 mins) so I was thinking to move to FFMPEG.
FFMPEG feels a lot faster (everything's done under 1 minute) but it has one big issue that makes the results useless: when compressing the source file, done with FFMPEG too, an extra gray frame is added at the beginning and this fakes the results because different frames are compared.
This is what I'm doing now (knowing that the extra frame messes it all):
ffmpeg -y -i src.avi -i compressed.avi -filter_complex "blend=all_mode=difference,hue=s=0" -c:v libx264 -crf 18 -c:a copy difference.avi
To fix the frame issue I was trying to remove the first frame by re-encoding the compressed video with this command
ffmpeg -y -ss 0.02 -i compressed.mpg -an -f mpeg2video compressed-cut.mpg"
(Note that -ss is 0.02 because it's a 50 fps video, so I did 1/FPS as suggested here)
But I get this response
Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)
So, finally, the question is: since extracting all the frames and then compute differences with OpenCV is really slow, how can I use FFMPEG to produce a video containing the difference between two sources while keeping in mind that one of them has an extra frame at the beginning?
EDIT: I wanted to avoid posting endless console outputs but since you asked for it, here we go.

The second command made everything work while the second one in the first part didn't (the one with the -ss option), so I could be quite happy about it but I'm not that sure if FFMPEG duplicates the first frame for every video or if it's just related to the one I'm using now, so it could be better to start off with a compressed video that has the same frame count of the original one.
So let's get to one final question: why does FFMPEG add a duplicated first frame at the beginning of the compressed video and how can I avoid that?
Encoding with
ffmpeg -i "720p50_mobcal_ter.avi" -c:v mpeg2video "720p50_mobcal_ter.mpg"
instead of
ffmpeg -i "720p50_mobcal_ter.avi" -an -f mpeg2video -y "720p50_mobcal_ter.mpg"
prevents the creation of the duplicate frame and makes everything work correctly.
I'm trying to convert a video to be played in a tag in a WebView in iOS. I've tried the options at this link but it still doesn't seem to play. I've found videos that do successfully play, though, so I'm sure it's possible, I just can't seem to get any working. Here's the ffmpeg -i output for something that works.
Here's what I tried from the wiki:
ffmpeg -i {filename} -acodec aac -ac 2 -strict experimental -ab 160k -vcodec libx264 -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 {filename}.ipad.mp4
But the file doesn't play in the WebView.

So, what is wrong in this streaming example, if I have no problem when I substitute streams to the files?
I create a mjpeg file using the same parameters 9i.e. file is an output insteadof stream)

And then I playback this mjpeg file with ffplay. The play back is correct, I see no errors or exceptions.

So, what is the configuration issue for ffserver, or may be it is a bug of the ffserver?
UPD. I have realized, that i fed file1.ffm instead of file.ffm; that caused some ffserver problem:

After i set a correct feed, i got another exception on ffmpeg side:

So, what is the problem now?
the short answer is: you can't do that, at least not in that way. ffserver decides the expected input format by looking at the feed output name. when it sees you sending the data to feed.ffm it assumes ffm data, and so when libavformat/utils.c routine avformat_open_input calls s->iformat->read_header(s), it uses the ffm_read_header routine in libavformat/ffmdec.c:
/* header */
tag = avio_rl32(pb);
if (tag == MKTAG('F', 'F', 'M', '2'))
return ffm2_read_header(s);
if (tag != MKTAG('F', 'F', 'M', '1')) {
ret = AVERROR_INVALIDDATA;
goto fail;
}
here is where it sees the <ff><d8><ff><e0> at the beginning of the JPEG data, sees it is not equal to FFM2 or FFM1, and fails with "Invalid data found when processing input", although that message is never shown.
I can't yet tell you the right way to do it, but at least now you know what is happening.
