I'm having problem encoding video using Laravel FFMPEG to save it to Minio storage
8 juillet 2022, par Ibrahim AhmadI am trying to convert video from .mp4 extension into HLS format (.m3u8) using Laravel FFMPEG.


FFMpeg::fromDisk('minio')
 ->open($videoFile)
 ->exportForHLS()
 ->onProgress(function ($percentage) use ($movie) {
 Cache::put('progress-' . $movie->id, $percentage);

 if($percentage >= 100) {
 Cache::forget('progress-' . $movie->id);
 }
 })
 ->toDisk('minio')
 ->addFormat($lowBitrate, function (HLSVideoFilters $filter) {
 $filter->resize(480, 360);
 })
 ->addFormat($midBitrate, function (HLSVideoFilters $filter) {
 $filter->resize(852, 480);
 })
 ->addFormat($highBitrate, function (HLSVideoFilters $filter) {
 $filter->resize(1920, 1080);
 })
 ->save($newFile);


I have a .mp4 video stored in Minio S3 storage, want to export to Minio S3 storage again. And I came up with this error


RecursiveDirectoryIterator::__construct(C:\Windows\Temp/52325dd01cfde90a\): Access is deni (code: 5)


What does the error message say ? But when I export the video file to local, it works totally fine. How do I solve this problem. Thanks.


Update :
The export process requires windows temporary folder, and I cleared the temporary folder, the problem is solved for now. This probably the temporary folder can't hold many files.

What do I need in order to save animation videos from matplotlib in mp3 format ?
27 juin 2022, par DarthMallocI am using python3.8 on Linux Mint 19.3, and I am trying to save an animation created by a cellular automata model in matplotlib. My actual code for the model is private, but it uses the same code for saving the animation as the code shown below, which is a slight modification of one of the examples shown in the official matplotlib documentation :


import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

fig, ax = plt.subplots()


def f(x, y):
 return np.sin(x) + np.cos(y)

x = np.linspace(0, 2 * np.pi, 120)
y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1)

fig, ax = plt.subplots()


 
ims = []
for i in range(60):
 x += np.pi / 15.
 y += np.pi / 20.
 im = ax.imshow(f(x, y), animated=True)
 if i == 0:
 ax.imshow(f(x, y)) # show an initial one first
 ims.append([im])

ani = animation.ArtistAnimation(fig, ims, interval=50, blit=True,
 repeat_delay=1000)

 # To save the animation, use e.g.
 #
 # ani.save("movie.mp4")
 #
 # or
 #
writer = animation.FFMpegWriter(fps=15, metadata=dict(artist='Me'), bitrate=1800)
ani.save("movie.mp3", writer=writer)


When executed, the code produces this error :


MovieWriter stderr:

I have looked at posts on similar queries concerning matplotlib animations, but none have specifically included the error
Output file #0 does not contain any stream. I have little experience with ffmpeg, so I am wondering what might be missing.

Cannot remove the video file created through ffmpeg save
29 juin 2022, par lightIt gives this error :
os.remove("output.mp4")
PermissionError : [WinError 32] The process cannot access the file because it is being used by another process : 'output.mp4


I am first downloading a reddit video (with separate audio and video file) by joining audio and video files together using ffmpeg


with open("video.mp4", "wb") as f:
 g = requests.get(video_url, stream=True)
 f.write(g.content)

 with open("audio.mp3", "wb") as f:
 g = requests.get(audio_url, stream=True)
 f.write(g.content)

 os.system("ffmpeg -i video.mp4 -i audio.mp3 -c copy output.mp4")
 os.remove("audio.mp3")
 os.remove("video.mp4")


After this I am uploading it to YouTube Using YouTube Api and then finally deleting it from the system. I tried everything I thought would solve this error.


os.system("exit")
 os.system("echo 'q' >stop") 
 os.system("exit()")
 os.remove("output.mp4")


But it gives me Permission Error. Please help me with this problem I have no idea what could be wrong.


This is the method I am using to upload the file to YouTube.


request_body = {
 'snippet': {
 'categoryI': 19,
 'title': f'{item.title}',
 'description': description,
 'tags': Tags
 },
 'status': {
 'privacyStatus': 'public',
 'publishAt': upload_date_time,
 'selfDeclaredMadeForKids': False, 
 },
 'notifySubscribers': False
 }


 mediaFile = MediaFileUpload(r"output.mp4")

 response_upload = service.videos().insert(
 part='snippet,status',
 body=request_body,
 media_body=mediaFile
 ).execute
