Scaling the denominator instead of the numerator if it is too large
loses precision. Fixes an assert caused by a negative frame duration in
the fuzzed sample nasa-8s2.ts_s202310.

Fixes ticket #1909.

I guess the user expects to see the stream with the highest bitrate, not with
the most frames, this is especially useful for multi bitrate streams.

This patch changes av_find_best_stream to select the stream based on a number
of conditions, the first condition has the highest priority, the last condition
has the lowest:

1) Select the stream with the highest FFMIN(5, codec_info_nb_frames) value
2) Select the stream with the highest bitrate
3) Select the stream with the highest codec_info_nb_frames
4) Select the first stream

The loop was introduced in 64d340c62ad5954c1a834df2d26057135e771774, and
was likely breaking non blocking reads as it busy loops.

This allows using avcodec_free_frame() to free it properly.

In particular, fix crash when the input file contains no packets (e.g. an
ffmeta input).

The channel layout at the demuxer layer is commonly wrong and would
otherwise be used.

This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is
called with a zeroed AVProbeData since no packet made through for
specific stream.

This also fixes a potential crash since s->pb can be NULL.
