The sample from ticket #2691 currently does not trigger "Consider increasing
the value for analzeduration and probesize" because the audio streams are
only added after calling estimate_timings(). Attached patch moves the message
below this function call.

This is part of normal operation with some formats. A warning should
indicate that something is wrong, and the documentation for AV_LOG_WARNING
says: "Something somehow does not look correct."

Since this message is most likely useful for debugging only, raise the
log level accordingly.

Also document that it has no effect.

If the demuxer implements read_seek2() and not read_seek(),
call avformat_seek_file() from av_seek_frame().
Allow to properly seek in formats that only implement the
new API from applications that use the old one.
Tested with mplayer and a concat script.

When a file appears to start with a id3 tag and appears to
also be something else, then try to increase the probe buffer
size if its below its limit.

To avoid allocating ridiculous amounts of memory for corrupted files,
read the input in chunks limited to filesize or an arbitrary large
amount when that is not known (chosen to be 50M).

This field is used and nothing equivalent exists

This will allow us to avoid copying the packets in many cases.

This breaks ABI.

Make sure the behavior does not change with the locale.
