Discord Music Bot interrupts music playback on Heroku
29 mars 2023, par denisnumbI have a music discord bot written in
Python
. Bot plays music from YouTube using theyt-dlp
library andffmpeg
.

Everything worked fine, but a couple of days ago the bot began to interrupt the playback of any tracks for
~80%
duration, crashing with an error :

[tls @ 0x6e3b440] Error in the pull function.
[tls @ 0x6e3b440] IO error: Connection reset by peer
[https @ 0x6e37900] Will reconnect at 720896 in 0 second(s), error=Connection reset by peer.



I have the latest version of
py-cord=2.4.1
andyt-dlp==2023.3.4
installed. When the bot is launched on my computer, the bot plays all the tracks to the end, so the problem is clearly not in the code and not in the libraries.

I suspect something is wrong with
ffmpeg
, so I tried installing different buildpacks, but that didn't solve the problem.

At the moment I have the following installed :


https://github.com/xrisk/heroku-opus.git
https://github.com/jonathanong/heroku-buildpack-ffmpeg-latest.git



What could be the problem and how to solve it ? Why did this problem appear only on hosting ? Why didn't this happen before ?

ffmpeg video processing command does not end
24 août 2023, par HarryI am using ffmpeg to create a video processing lambda, I attached the log for the processing input below and the process never completes sometimes and other times it takes no more than 2 minutes. This also does not throw and error but just does not complete for certain videos.

The intention is to provide two videos with varying lengths and have them stack on top of each other vertically with subtitles and a length of the shortest video.
I am running the function in a lambda and even with a timeout of 10 minutes it does not complete for certain videos but for others it does complete, please help me to resolve this.

lavc/vvc : Validate IBC block vector
25 juin 2024, par Frank Plowmanlavc/vvc : Validate IBC block vector
From H.266 (V3) (09/2023) p. 321 :
It is a requirement of bitstream conformance that the luma block
vector bvL shall obey the following constraints :CtbSizeY is greater than or equal to
((yCb + (bvL[ 1 ] >> 4)) & (CtbSizeY − 1)) + cbHeightThis patch checks this is true, which fixes crashes on fuzzed
