OSError : [Errno 9] Bad file descriptor when downloading using pytube and playing with discord.py
15 septembre 2022, par Trevor MathisenWhen using pytube to download a YouTube video and discord.py to play it, I am getting a OSError : [Errno 9] Bad file descriptor error. I've had this working at one point and can't seem to figure out what I changed which broke it.

I've mounted the /media/ dir during docker -v and can see the file is getting downloaded and when I copy the file to my local machine I can play it in an audio player.


The program can access the SQLite database right next to the files in question just fine.


I've deployed the container locally and to two different VPS's with the same file structure with the same behavior. I'm ripping my hair out.

FFMPEG Loudnorm reading JSON data
9 juillet 2022, par NineCattoRulesI tried to normalize some audio files using FFMPEG Loudnorm as described here.


However, in Python, I don't understand how to read data info from 1st pass.


My code :


getLoud = subprocess.Popen(f"ffmpeg -i {file_path} -filter:a loudnorm=print_format=json -f null NULL", shell=True, stdout=subprocess.PIPE).stdout
getLoud = getLoud.read().decode()
# parse json_str:
jsonstr_loud = json.loads(getLoud)



This gives me
"errorMessage": "Expecting value: line 1 column 1 (char 0)"


I tried also this :


os.system(f"ffmpeg -i {file_path} -filter:a loudnorm=print_format=json -f null NULL")



and it outputs :


ffmpeg version N-60236-gffb000fff8-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2022 the FFmpeg developers...
...
[Parsed_loudnorm_0 @ 0x5921940] 
{
 "input_i" : "-9.33",
 "input_tp" : "-0.63",
 "input_lra" : "0.60",
 "input_thresh" : "-19.33",
 "output_i" : "-24.08",
 "output_tp" : "-15.40",
 "output_lra" : "0.60",
 "output_thresh" : "-34.08",
 "normalization_type" : "dynamic",
 "target_offset" : "0.08"
}



In Python, how can I use those parameters, such as
input_i
,input_tp
etc. that I need for the 2nd pass ?

I can't use
ffmpeg-normalize
because I'm using FFMPEG as a Layer in Lambda.

ffmpeg failing to add png mask to video : Requested planes not available
23 août 2022, par Alexandr SugakI am trying to add png mask to make webm video round (cut off its corners).


The command I am using :


video="./dist/tmp/19_2.webm"
mask="./dist/tmp/mask.png"
output="./dist/tmp/circle.webm"

ffmpeg -report -c:v libvpx-vp9 -i "${video}" -loop 1 -i "${mask}" -filter_complex " \
[1:v]alphaextract[alf];\
[0:v][alf]alphamerge" \
-c:a copy -c:v libvpx-vp9 "${output}"



The command output :

Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
Conversion failed!



I've tried different combination of codecs and pixel formats but I still get the same error. My initial understanding was that ffmpeg fails to find the alpha channel in the input video. By setting
-c:v libvpx-vp9
option it looks like ffmpeg correctly picks upyuva420p
pixel format but it still gives the same error.

What I am doing wrong ?


Update : if I remove the alphaextract step as suggested in comments, the ffmpeg starts processing video indefinitely (the video I use to test is only 2 sec long). If I specify the number of frames manually, then the output is generated but the mask does not seem to have any effect :


ffmpeg -c:v libvpx-vp9 -i "${video}" -loop 1 -i "${mask}" -filter_complex " \
[0:v][1:v]alphamerge" \
-c:a copy -b:v 2000k -vframes 60 "${output}"
