The previous code expected a segment of type CLUT definition to

This is allowed to read fewer bytes than requested. The missing bytes can
be read in the next call.
I don't think this is needed, after all we want to read all data, there is
no point in reading it in smaller chunks, no?

fftools/ffmpegc When `ost->last_frame` is NULL, 'SEGV' occurs when accessing
its pts.
libavutil/framec `ost->last_frame` may be set NULL by av_frame_alloc(). In this
situation，
av_frame_unref() and av_frame_free() do nothing. Frame is not
released.

'pkt' and '*pkt' should be judged separately for release.
SEGV by a READ memory access (address points to the zero page)
```c
// in fftools/ffmpeg.c:515
515 static void ffmpeg_cleanup(int ret)
516 {
...
626 for (i = 0; i < nb_input_files; i++) {
627
Opts is assigned by setup_find_stream_info_opts(). Opts may be NULL.
This situation is compatible in avformat_find_stream_info().
Before av_dict_free(), the necessary checks were ignored.
// in fftools/ffmpeg_opt.c:1266
1067 static int open_input_file(OptionsContext *o, const char *filename)

I have added the reference to ST2019-4 for "VC3 mapping", so that should be ok
for generic standard files.
It seems redundant for me, but if you want,

Split packed data when it contains multiple show frames in some
non-standard bitstream. This can benefit downstream decoder which can
decode continuously instead of interrupt with unexpected error.
