Description

I want to see SRT error message somethings like below: av_log(h, AV_LOG_ERROR, "%s\n", srt_getlasterror_str());

but when I use FFmpegLogCallback like this:

FFmpegLogCallback.setLevel(AV_LOG_TRACE);
FFmpegLogCallback.set();

I can't see any ERROR log,only some debug and info logs,I'm sure to trigger the error condition. thanks for help. @saudet

Contributor guide

Research direction
Investigate the mapping of FFmpeg log levels to JavaCV's FFmpegLogCallback. Check if setting the level to AV LOG TRACE correctly enables all levels including AV LOG ERROR. Look at the source code of FFmpegLogCallback to understand how it filters logs. Ensure that the callback is set after the level is set.
