ffmpeg opening a blu-ray?

[Selur]

Trying to open the old x264 BR-Demo using:
"F:\Hybrid\64bit\ffmpeg.exe" -loglevel debug -i "bluray:G:\TestClips&Co\discs\Blu-ray\x264 BR-Demo"
fails

This did work with older versions.

Using:
"F:\Hybrid\64bit\ffmpeg.exe" -loglevel debug -i "bluray:G:\TestClips&Co\discs\Blu-ray\x264 BR-Demo\"

Since I couldn't find any info over at https://ffmpeg.org/ffmpeg-all.html

Does anybody know what could be wrong?

I tried a 'full'-build from https://www.gyan.dev/ffmpeg/builds/ and it failed too with the 'No default whitelist set' :/

Does ffmpeg 6.x work for anyone with libbluray?

Your last try seems to be the most successful.

According to the libbluray source code the error "../src/libbluray/disc/disc.c:333: failed opening UDF image G:\TestClips&Co\discs\Blu-ray\x264 BR-Demo" gets triggered when the lib failed to open the path as a directory before.

So maybe there is a problem with the path? Have you tried copying the folder somewhere else? Maybe somewhere relative?

I agree that this likely is somehow related to the path, since a Hybrid user reported that it works on Linux with FFmpeg 6.0 and libbluray 1.3.4, but he has the problem on windows.

Renaming the folder to "x264-BR-Demo" does seem to work.
So seems like ffmpeg and/or libbluray has issues with any 'special' character (even white spaces) :(

[Selur]

It does work if one uses '8.3 filename' (assuming short filename creation is enabled, which it is not always in Windows nowadays)

[rwill]

I would try some escape combinations like "G:\\TestClips&Co\\discs\\Blu-ray\\x264\ BR-Demo" (with or without the quotes).

But I am afraid I cannot be of help, I am no Windows Path expert.

[Selur]

tried that didn't help :(
also the 8.3 workaround does only seem to work with the build from https://www.gyan.dev/ffmpeg/builds/ not with the one from MBAS
=> will try to look more into it tomorrow. :(

gaynet-builds work
ffmpeg-6.1.1-full_build\bin>ffmpeg.exe -loglevel debug -i "bluray:G:\TestClips&Co\discs\Blu-ray\x264 BR-Demo"
ffmpeg-6.0-full_build\bin>ffmpeg.exe -loglevel debug -i "bluray:G:\TestClips&Co\discs\Blu-ray\x264 BR-Demo"
MBAS builds to not.
=> going to contact the MBAS folks. (https://github.com/m-ab-s/media-autobuild_suite/issues/2627)
