* avformat/smoothstreamingenc: Move buffers to the end of structsAndreas Rheinhardt2021-12-05
| | | | | | | | This reduces codesize because the offsets of commonly used elements are now smaller and thus need less bytes to encode in ptr+offset addressing modes (with GCC 11.2 on x64: 0x1b8b -> 0x1a7b). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avformat: do not use AVIO_FLAG_* with avio_alloc_contextMarvin Scholz2021-12-04
| | | | | | | | | | | | | The documentation states that here 0 should be used for read-only and 1 for a writable buffer. AVIO_FLAG_WRITE however is 2, while it works due to the way the flag is handled internally, it is still wrong according to the documentation. Additionally it makes it seem as if the AVIO_FLAG_* values could be used here, which is actually not true, as when AVIO_FLAG_READ would be used here it would create a writable buffer as AVIO_FLAG_READ is defined as 1.

* avformat: Avoid allocation for AVStreamInternalAndreas Rheinhardt2021-09-17
| | | | | | | | | | Do this by allocating AVStream together with the data that is currently in AVStreamInternal; or rather: Put AVStream at the beginning of a new structure called FFStream (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove AVStreamInternal altogether.

* avformat/smoothstreaming: Don't write trailer of subcontextAndreas Rheinhardt2020-06-27
| | | | | | | | | | Nothing written in avformat_write_trailer() for the submuxers will be output anyway because the AVIOContexts used for actual output have been closed before the call. Writing the trailer of the subcontext has probably only been done in order to free the memory allocated by the submuxer. And this job has been taken over by the deinit functions.

* avformat/smoothstreaming: Fix memleaks on errorsAndreas Rheinhardt2020-03-14
| | | | | | | | | | | | | | If an AVFormatContext could be allocated, but white-/blacklists couldn't be copied, the AVFormatContext would leak as it was only accessible through a local variable that goes out of scope when one goes to fail. Furthermore, in case writing a header of a submuxer failed, the options used for said call could leak. Both of these memleaks have been fixed.

| * avio: Copy URLContext generic options into child URLContextsMartin Storsjö2016-03-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since all URLContexts have the same AVOptions, such AVOptions will be applied on the outermost context only and removed from the dict, while they probably make sense on all contexts. This makes sure that rw_timeout gets propagated to the innermost URLContext (to make sure it gets passed to the tcp protocol, when opening a http connection for instance). Alternatively, such matching options would be kept in the dict and only removed after the ffurl_connect call. Signed-off-by: Martin Storsjö <martin@martin.st>

| * 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.
