This allows setting the right fragment number if doing random-access writing of fragments, and also allows reading the current sequence number. Signed-off-by: Martin Storsjö <martin@martin.st>

This allows creating a later mp4 fragment without sequentially writing the earlier ones before (when called from a segmenter). Normally when writing a fragmented mp4 file sequentially, the first timestamps of a fragment are adjusted to match the end of the previous fragment, to make sure the timestamp is the same, even if it is calculated as the sum of previous fragment durations. (And for the first packet in a file, the offset of the first packet is written using an edit list.) When writing an individual mp4 fragment discontinuously like this (with potentially writing the earlier fragments separately later), there's a risk of getting a gap in the timeline if the duration field of the last packet in the previous fragment doesn't match up with the start time of the next fragment. Using this requires setting -avoid_negative_ts make_non_negative (or -avoid_negative_ts 0). Signed-off-by: Martin Storsjö <martin@martin.st>

Keep the code as similar as possible across the codepaths to ease spotting it for factorization. Based on a patch from Michael Niedermayer <michaelni@gmx.at>.

The code currently set the information in at least 4 places, spare some pointless loops. Make the code in the loop a little uniform to make easier factorize it out later.

This makes sure that the internal utf8 path names are handled properly - the normal file handling functions assume path names are in the native codepage, which isn't utf8. This assumes that the tools outside of lavf don't use the mkdir definition. (The tools don't do the same reading of command line parameters as wchar either - they probably won't handle all possible unicode file parameters properly, but at least work more predictably if no utf8/wchar conversion is involved.) This is moved further down in os_support.h, since windows.h shouldn't be included before winsock2.h, while io.h needs to be included before the manual defines for lseek functions.

On windows, rename(2) will fail if the target file exists. On unix this trick is used to make sure that people reading the file either will get the full previous file, or the full new version of the file, but no intermediate version. Signed-off-by: Martin Storsjö <martin@martin.st>

Don't write any bitrate attribute if it isn't known. As long as one doesn't want automatic bitrate switching, playback can work just fine even if it isn't set. If strict standard compliance is requested, this is still considered an error, since the attribute is mandatory according to the spec. Based on a patch by Rodger Combs.

The chained flv muxer wants one set of tags - normally this set could be signaled via the AVOutputFormat codec_tag field (as smoothstreamingenc and dashenc do). hdsenc doesn't signal it, since the FLV codec tag arrays aren't exported from flvenc.c. This can lead to the caller keeping an original codec tag from the originating container here, which would then be a mismatch for the FLV muxer. Since we don't really care about what codec tag the caller might have set, just clear it and let the lavf muxer layer set the right one for the chained FLV muxer later instead.
