79551d2c7a avcodec/utils: Force mutex to NULL after destruction. 
A badly behaving user provided mutex manager (such as that in OpenCV) may not reset the mutex to NULL on destruction.  This can cause a problem for a later mutex manager (which may assert that the mutex is NULL before creating).

This allows the application to fall back on another hwaccel or,
more likely, software decoding.

ef0c466a0f Replace assert with AVERROR when recode_subtitle called w/o ICONV. 
recode_subtitle() is called implicitly by avformat_find_stream_info().
As such, clients which disable ICONV always crash if a file contains
subtitles; even if they don't care about them.

f6774f905f mpegvideo: operate with pointers to AVFrames instead of whole structs 
The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().

ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.

NULL pointer checks are added to ff_thread_release_buffer() stub function.

This is a bit tricky, we allocate a correctly sized AVFrame but then only
copy the compile time AVFrame size, this is to ensure that user applications
which do not use the correct av frame API dont end with out of array reads.
Note, applications using the correct API have set extended_data and the
changed code will never be executed for them.

01923bab98 avcodec: move end zeroing code from av_packet_split_side_data() to avcodec_decode_subtitle2() 
This code changes the input packet, which is read only and can in
rare circumstances lead to decoder errors. (i run into one of these in
the audio decoder, which corrupted the packet during av_find_stream_info()
so that actual decoding that single packet failed later)
Until a better fix is implemented, this commit limits the problem.
A better fix might be to make the subtitle decoders not depend on
data[size] = 0 or to copy their input when this is not the case.
