* avformat: introduce AVFormatContext io_close2 which returns an intMarton Balint2021-12-12
| | | | | | | | | | | | | | | | | Otherwise there is no way to detect an error returned by avio_close() because ff_format_io_close cannot get the return value. Checking the return value of the close function is important in order to check if all data was successfully written and the underlying close() operation was successful. It can also be useful even for read mode because it can return any pending AVIOContext error, so the user don't have to manually check AVIOContext->error. In order to still support if the user overrides io_close, the generic code only uses io_close2 if io_close is either NULL or the default io_close callback.

* avformat/avformat: Add AVStream parameter to check_bitstream() sigAndreas Rheinhardt2021-11-27
| | | | | | | | | | For most check_bitstream() functions this just avoids having to dereference s->streams[pkt->stream_index] themselves; but for meta-muxers it will allow to forward the packet to stream with a different stream_index (belonging to a different AVFormatContext) without using a spare packet.

* avformat/dashenc: enabling streaming and hls_playlist for lhlsZhao Zhili2021-11-05
| | | | | | | Try to make the feature easier to use, especially since the user have enabled -strict experimental manually. The user shouldn't be surprised that hls_playlist is enabled for lhls automatically, so change the log level from warning to info for that.
* avformat/dashenc: enabling streaming automatically for ldashZhao Zhili2021-11-05
| | | | | | | | | There is a little chance that user specified contradicted options like -streaming 0 -ldash 1, however, it's more likely that user didn't know or forgot to enable streaming for ldash. So enabling streaming automatically to make the feature easier to use, similar like enable FF_MOV_FLAG_FRAGMENT/EMPTY_MOOV/DEFAULT_BASE_MOOF and so on for FF_MOV_FLAG_CMAF.

* 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/internal: Move ff_read_line_to_bprint_overwrite to avio_internal.hAndreas Rheinhardt2021-07-29
| | | | | | | | | | | | | It only uses an AVIOContext and an AVBPrint. When doing so, it turned out that several non-users of ff_read_line_to_bprint_overwrite() and ff_bprint_to_codecpar_extradata() relied on libavformat/internal.h to include bprint.h or avstring.h for them. In order to avoid a repeat of this and in order to reduce unnecessary dependencies, a forward declaration of struct AVBPrint is used instead of including bprint.h.

* Fix double write of DASH manifest in streaming modeKevin LaFlamme2021-07-14
| | | | | | | When streaming mode is enabled, the DASH manifest is written on the first packet for the segment so that the segment can be advertised immediately to clients. It was also still writing the manifest at the end of the segment leading to two duplicate writes.
* dashenc: Write out DASH manifest immediately in streaming modeKevin LaFlamme2021-06-14
| | | | | | | | | | | | | | When streaming mode is enabled with fMP4/CMAF for DASH output, the segment files are available to read by players as soon as the first byte is written instead of only after the file is fully written. The DASH manifest currently only gets written when the final write to the segment file occurs. This means that players cannot stream the first segment while it is being written. When -lhls is enabled with MP4 segments the HLS manifest is written immediately to advertise the in-flight segments. This change adds the same behavior for the DASH manifest so players can stream it immediately.

* avformat: only allow a single bitstream filter when muxingMarton Balint2020-04-26
| | | | | | | | | | | | Current muxers only use a single bitstream filter, so there is no need to maintain code which operates on a list of bitstream filters. When multiple bitstream filters are needed muxers can simply use a list bitstream filter. If there is a use case in the future when different bitstream filters should be added at subsequent packets then a new API possibly involving reconfiguring the list bitstream filter can be added knowing the exact requirements.
