* avformat/avformat: Move AVOutputFormat internals out of public headerAndreas Rheinhardt2023-02-091-18/+19
| | | | | | | | | | | | | | This commit does for AVOutputFormat what commit 20f972701806be20a77f808db332d9489343bb78 did for AVCodec: It adds a new type FFOutputFormat, moves all the internals of AVOutputFormat to it and adds a now reduced AVOutputFormat as first member. This does not affect/improve extensibility of both public or private fields for muxers (it is still a mess due to lavd).

* avformat/wavenc: Fix leak and segfault on reallocation errorAndreas Rheinhardt2021-02-271-24/+29
| | | | | | | | | | | | | | | | | | | | | Up until now, the wav muxer used a reallocation of the form ptr = av_realloc(ptr, size); that leaks upon error. Furthermore, if a failed reallocation happened when writing the trailer, a segfault would occur due to avio_write(NULL, size) because the muxer only prints an error message upon allocation error, but does not return the error. Moreover setting the pointer to the buffer to NULL on error seems to be done on purpose in order to record that an error has occured so that outputting the peak values is no longer attempted. This behaviour has been retained by simply disabling whether peak data should be written if an error occurs. Finally, the reallocation is now done once per peak block and not once per peak block per channel; it is also done with av_fast_realloc and not with a linear size increase.

* avformat: remove more unneeded avio_flush() callsMarton Balint2020-01-071-7/+0
| | | | | | | | | | | | These instances are simply redundant or present because avio_flush() used to be required before doing a seekback. That is no longer the case, aviobuf code does the flush automatically on seek. This only affects code which is either disabled for streaming IO contexts or does no seekbacks after the flush, so this change should have no adverse effect on streaming.

* avformat: remove avio_flush() calls from the end of write_header functionsMarton Balint2020-01-071-2/+0
| | | | | | | | | | | | | | To make it consistent with other muxers. The user can still control the generic flushing behaviour after write_header (same way as after packets) using the -flush_packets option, the default typically means to flush unless a non-streamed file output is used. Therefore this change should have no adverse effect on streaming, even if it is assumed that the first packet has a clean buffer, so small seekbacks within the output buffer work even when the IO context is not seekable.

* avformat/wavenc: skip writing incorrect peak-of-peaks position valueTobias Rapp2017-10-261-10/+1
| | | | | | | | | | | | | | According to EBU tech 3285 supplement 3 the dwPosPeakOfPeaks field should contain the absolute position to the maximum audio sample value, but the current implementation writes the relative peak frame index instead. Fix the issue by writing the "unknown" value (-1) for now until the feature is implemented correctly.

| | | | | | | | | | | | | | | | It is supposed to be a flag. The only currently defined value is AVIO_SEEKABLE_NORMAL, but other ones may be added in the future. However all the current lavf code treats this field as a bool (mainly for historical reasons). Change all those cases to properly check for AVIO_SEEKABLE_NORMAL.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-231-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This flag is used in the Matroska muxer (the cause of the original change) and in the ASF muxer, because the specifications for these formats indicate explicitly that WAVEFORMATEX should be used. Muxers for other formats will return to the original behavior of writing PCMWAVEFORMAT when writing a header for raw PCM. In particular, this causes raw PCM in WAV to generate the canonical 44-byte header expected by some tools. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
