```julia cam = opencamera() VideoIO.framerate(cam) ``` gives `1//0`. The webcam works normally. ``` Julia Version 1.7.3 Commit 742b9abb4d (2022-05-06 12:58 UTC) Platform Info: OS: Windows (x86_64-w64-mingw32) CPU: Intel(R) Core(TM) i7-8550U...
``` julia> VideoIO.framerate(video_reader) 1//0 ``` but if instead i examine the [code](https://github.com/JuliaIO/VideoIO.jl/blob/master/src/avio.jl#L843) for `seek` i can get the correct value: ``` julia> convert(Rational, video_reader.avin.format_context.streams[1].time_base) 1//10 ``` the `framerate` [method](https://github.com/JuliaIO/VideoIO.jl/blob/master/src/avio.jl#L368) is...

The error seen here is difficult to figure out because we don't auto convert the error number to a meaningful message, which I believe should be straightforward https://discourse.julialang.org/t/videoio-avformat-open-input-error-code-5/81758

When I write a video with RGB{N0f8} the video isn't viewable by any video player. I am running julia with a mac M1 Monterey ``` Julia Version 1.7.2 Commit bf53498635...
When encoding a video with large frames, Julia crashes because the system runs out of memory. I made the following MWE to illustrate this (I stole @yiyuezhuo `get_memory_usage` function from...
For the type `Ptr{VideoIO.libffmpeg.AVCodecContext}`, `propertynames` returns values that don't work with `getproperty`. See an example at https://github.com/tshort/Eyeball.jl/issues/24.
I'm trying to fetch frames from a Raspberry Pi camera (headless Raspbian on 32-bit ARMv7). I also tired @hhaensel's solution mentioned here: https://github.com/JuliaIO/VideoIO.jl/issues/341#issuecomment-1012974406 ```julia (tmp) pkg> st Status `~/tmp/Project.toml` [d6d074c3]...
