While rebuilding freerdp against libav 9 I've noticed the following
warnings:

|     len = avcodec_decode_audio3(mdecoder->codec_context,

|    avcodec_init();

This will make tsmf_ffmpeg.so unusuble once freerdp gets rebuilt for the
libav 9 transition. At least avcodec_alloc_context got removed from
libav. Since I don't know if this makes freerdp unusuble or not, I'm
filing this as severity normal bug. Please check if this problem.

This issue has been dealt with during the libav10 transition. I forgot closing this bug back then...
