dec880031d asfdemux: Reset number of languages to 0 when freeing the array because of errors
Otherwise we will happily index into the array at NULL if the requested
index is smaller than the number of languages that were previously
allocated.

97294eb8bb asfdemux: Add check for invalid/corrupt asf object
An asf object can't realistically be bigger than 2**32 bytes.

If it reports a size bigger than that, consider it corrupt and properly
propagate the error back.

45c7826d76 asfdemux: Handle issues with "empty" files
In some corrupted files, we could end up with no actual streams
being exposed.

In those cases, make sure we properly propagate the failure all
the way to the loop function. This avoids ending up in cases where
we are neither EOS'd nor ERROR'd out from a pipeline point of view.

6ff1c761e4 asfdemux: fix seeking back after EOS has been reached in push mode
Fix seeking when demuxer is in INDEX state. This happens when we
reached the end of the stream. It should still be possible to do
a flushing seek and seek back to any other position though. Instead
the demuxer would just go straight to EOS again instead of going
back to processing packets again from the new position.

We don't want to unconditionally send an EOS event downstream, but might want

before.

to handle it in asfdemux.

were not supported by asfdemux.

2863d9ae00 asfdemux: if video is h264, check the codec_data for bytestream data
For bytestream we don't want to expose it as codec_data but rather as
streamheader as it is not out-of-band data but data that should be
prepended to the beginning of the stream before the other buffers.

556055e2f1 asfdemux: Only use segment.start as seek_time if it is relative
Relying on the gst_segment_do_seek results for getting the
seeking time should not be used if seek type is SET because the
do_seek function makes the 'cur` position of the seek normalized
on the segment range. This means that seeking beyond the end of the
file might not result in instant EOS as it will end up seeking to
the final ts of the file.

In asf seeking to the final timestamp can lead to seeking to the last
keyframe, meaning a few seconds of video will still be played, which should
not be the desired behavior when seeking beyong file limits.
