## If you're seeing the error "could not determine kind of name for C.AV_CODEC"
|

|

Make sure you're using ffmpeg `"n5.1.2"` (via `make install-ffmpeg`), go-astiav@v0.12.0 only supports ffmpeg 5.0.

## If you're seeing the error "issue /usr/bin/ld: skipping incompatible lib.so when searching for -lavdevice"
|

|

Fixing the docker platform fixed the problem. Even though the configured platform is amd64, the final objects are x64, don't know why yet.
|
||||
|
||||
```
|
||||
# The tools to check the compiled objects format:
|
||||
find / -name libsrt.so # to find the objects
|
||||
objdump -a /opt/srt_lib/lib/libsrt.so
|
||||
objdump -a /usr/local/lib/libavformat.so
|
||||
```

## If you're seeing the error "checkptr: converted pointer straddles multiple allocations" when using -race

|

When the app runs using `go build -race` it stops with the error "converted pointer straddles multiple allocations". I tried to upgrade the golang image but it didn't work, so I remove the `-race` from building.
