[Joris Kraak]

Thanks for reporting! This is the equivalent of JuliaIO/TranscodingStreams.jl#139 and appears to be caused by changes made to the signature for transcode in JuliaIO/TranscodingStreams.jl#136.

I could try to work around this here, but this seems like an issue that should be fixed in TranscodingStreams instead. If you need a quick fix, you can pin TranscodingStreams to v0.9.11 which appears to be working from some quick tests.

[Joris Kraak]

This has been resolved through JuliaIO/TranscodingStreams.jl#141 which has been released in TranscodingStreams@0.9.13. This should now be working again as expected.
