* movenc: Use packets in interleaving queues for the duration at the end of ↵Martin Storsjö2016-05-18
| | | | | | | | | | | | | | fragments As long as caller only writes packets using av_interleaved_write_frame with no manual flushing, this should allow us to always have accurate durations at the end of fragments, since there should be at least one queued packet in each stream (except for the stream where the current packet is being written, but if the muxer itself does the cutting of fragments, it also has info about the next packet for that stream).

* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
* lavf: allow custom IO for all filesAnton Khirnov2016-01-24
| | | | | | | | | | | | | | Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.

* lavf: deprecate compute_pkt_fields2Anton Khirnov2015-11-09
| | | | | | | | | All encoders set pts and dts properly now (and have been doing that for a while), so there is no good reason to do any timestamp guessing in the muxer. The newly added AVStreamInternal will be later used for storing all the private fields currently living in AVStream.
* avpacket: Replace av_free_packet with av_packet_unrefLuca Barbato2015-10-26
| | | | | | | `av_packet_unref` matches the AVFrame ref-counted API and can be used as a drop in replacement. Deprecate `av_free_packet`.

* Revert "lavf: Don't try to update files atomically with renames on windows"Martin Storsjö2014-11-27
| | | | | | | | | This reverts commit b9d08c77a44390b0848c06f20bc0e9e951ba6a3c. After taking MoveFileEx into use, we can replace files with renames on windows as well. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Use wchar functions for filenames on windows for mkdir/rmdir/rename/unlinkMartin Storsjö2014-11-24
| | | | | | | | | | | | | | | | | | 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.

* lavf: Don't try to update files atomically with renames on windowsMartin Storsjö2014-11-24
| | | | | | | | | 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.

* lavf: eliminate ff_get_audio_frame_size()Anton Khirnov2014-08-13
| | | | | | | | | | | | | | | It is basically a wrapper around av_get_audio_frame_duration(), with a fallback to AVCodecContext.frame_size. However, that field is set only when the stream codec context is actually used for encoding or decoding, which is discouraged. For muxing, it is generally the responsibility of the caller to set the packet duration. For demuxing, if the duration is not stored at the container level, it should be set by the parser. Therefore, removing the frame_size fallback should not break any important case.

* lavf: Handle the environment variable no_proxy more properlyMartin Storsjö2013-02-27
| | | | | | | | | | | | | | | | | | | | The handling of the environment variable no_proxy, present since one of the initial commits (de6d9b6404), is inconsistent with how many other applications and libraries interpret this variable. Its bare presence does not indicate that the use of proxies should be skipped, but it is some sort of pattern for hosts that does not need using a proxy (e.g. for a local network). As investigated by Rudolf Polzer, different libraries handle this in different ways, some supporting IP address masks, some supporting arbitrary globbing using *, some just checking that the pattern matches the end of the hostname without regard for whether it actually is the right domain or a domain that ends in the same string. This simple logic should be pretty similar to the logic used by lynx and curl. Signed-off-by: Martin Storsjö <martin@martin.st>

* frame{crc/md5}: set the stream timebase from codec timebase.Anton Khirnov2012-02-03
| | | | | | | | | | | | | Right now those muxers use the default timebase in all cases(1/90000). This patch avoid unnecessary rescaling and makes the printed timestamps more readable. Also, extend the printed information to include the timebases and packet pts/duration and align the columns. Obviously changes the results of all fate tests which use those two muxers.
