The place is so peaceful that it's more like a vacation … until they're attacked by a villain with an unfathomable Quirk! His power is eerily familiar, and it looks like Shigaraki had a hand in the plan. But with All Might retired and citizens' lives on the line, there's no time for questions. Deku and his friends are the next generation of heroes, and they're the island's only hope.

Conan OpenCV with FFMPEG
20 April 2020, by BixileinFor my project I would like to use OpenCV from conan. For my application I need OpenCV with the FFMPEG option enabled.



I tried to do
conan install opencv/4.1.1@conan/stable -o ffmpeg=True -b missing
but I got a lot of compiler errors with undefined references. All the errors are related to FFMPEG.


In the conanfile of opencv
ffmpeg/4.2@bincrafters/stable
is listed as a requirement. I tried to just installfmpeg/4.2@bincrafters/stable
but I got the same errors. After some experimenting, I found out thatfmpeg/4.2.1@bincrafters/stable
is working on my system.


Therefore, I wanted to use this working version of ffmpeg for OpenCV. In the conan-cache I changed the conanfile for OpenCV to take ffmpeg/4.2.1 and then tried again to install OpenCV. This time everything build without error and a new hash was created.



Now I wanted to use this OpenCV in my project. But when I try to build my project, I get an error. The problem seems to be that conan is looking for a specific hash and because I changed the requirements in the conanfile of OpenCV the hash is now different. The hash of my local OpenCV is
91716d2466cac1ff5c91a7b802ce2d69b84cc798
, but when I try to build my project it is looking for a different hash. (opencv/4.1.1@conan/stable:7234edbe78e5002a4384cde97bca91abd732a248 - Missing
)


I am new to conan and therefore I do not know if the approach I took so far is acceptable. I appreciate every feedback on how to approach this problem.

Removing one audio track from a movie results in audio desync when copying, but not when reencoding --- why?
18 April 2020, by chskI'm trying to remove a superfluous audio track from a movie file. Specifically, this movie on
archive.org
has the original audio as track 2, and what appears to be a slavic (Russian?) voiceover in track 1. I'd like to get rid of the latter.


I found this question that suggested I should do the following:



ffmpeg -i Benjamín\ dúfa.avi -map 0 -map -0:a:0 -c copy Benjamín\ dúfa\ \(aðeins\ íslenskt\ tal\).avi



But this doesn't work: after removing the first audio track, audio and video are not in sync in the resulting file anymore (when played in VLC). Now, I was able to overcome this problem by also reencoding the remaining audio track along the way, using



ffmpeg -i Benjamín\ dúfa.avi -map 0 -map -0:a:0 -c:v copy Benjamín\ dúfa\ \(aðeins\ íslenskt\ tal\).avi



But while this works, I'd like to understand why copying the audio track instead does not. I suppose it's a somewhat philosophical question --- consider it a matter of intellectual curiosity, combined with an aversion to needless lossy re-encoding.



So if anyone can explain this to me, I'd very grateful. Thanks!



EDIT: as per Gyan's request, here's ffmpeg's output for the first command:
