* tests/Makefile: Add auxiliary functions for transcode and stream_remuxAndreas Rheinhardt2022-04-14
| | | | | | | | | | | | | | | | | Tests using the transcode and stream_remux functions have some common requirements (namely the file and pipe protocols as well as the framecrc muxer) and also other commonalities: The create a file and read it immediately afterwards, so that they typically rely on a corresponding muxer+demuxer pair which typically shares the same name; for transcode (if it does not use stream copy) the same is true for encoders and decoders. This means that using special Makefile-functions instead of the general ALLYES is worthwhile. This commit adds such functions. These functions allow to add arbitrary CONFIG-checks on top of the aforementioned ones in order to satisfy special needs (for e.g. parsers, filters) that several intended users have.

* avcodec/mjpegenc: Don't unnecessarily grow bufferAndreas Rheinhardt2022-04-14
| | | | | | | | | The size of the ICC chunk has already been accounted for when the packet's buffer was initially set in ff_mpv_encode_picture() and the header (including the ICC chunk) has already been written at this point. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo_enc: Remove always-true checkAndreas Rheinhardt2022-04-14
| | | | | | | It is a remnant of the old way for user-supplied buffers; it is always-true since 93016f5d1d280f9cb7856883af287fa66affc04c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo_enc: Fix unnecessary linear growth of bufferAndreas Rheinhardt2022-04-14
| | | | | | | | | | | If one encodes MJPEG with a single slice and uses input with AV_FRAME_DATA_ICC_PROFILE side data, the current allocation code in ff_mpv_encode_picture() will always increase the size of the temporary buffer used for allocating packets by the size needed for to write the ICC chunk even when the current buffer is actually large enough. This commit fixes this. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mpegvideo_enc: Ignore ICC profile size when not MJPEGAndreas Rheinhardt2022-04-14
| | | | | | | | MJPEG is the only mpegvideo-based encoder making use of it. Fixes linking failures in case mpegvideo_enc.c is compiled with AMV, LJPEG and MJPEG encoders disabled. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | | PATH_MAX is posix. Some compilers (MSVC) don't define this thus failing to compile the ipfsgateway file. Defining it fixes the compile. Signed-off-by: Mark Gaiser <markg85@gmail.com> Signed-off-by: Martin Storsjö <martin@martin.st>

* lavc: move default get_buffer2() to its own fileAnton Khirnov2022-04-13
| | | | | It is also used by some encoders, so decode.c is not the right place for it.
* lavc/encode: drop EncodeSimpleContextAnton Khirnov2022-04-13
| | | | It has only a single member.
* lavc/avcodec: only allocate the encoding frame for encodersAnton Khirnov2022-04-13

* lavc/avcodec: simplify codec id/type validity checkingAnton Khirnov2022-04-13
| | | | | On entry to avcodec_open2(), the AVCodecContext type and id either have to be UNKNOWN/NONE or have to match the codec to be used.
* fftools/ffmpeg: store output format separately from the muxer contextAnton Khirnov2022-04-13
| | | | | | Allows accessing it without going through the muxer context. This will be useful in the following commits, where the muxer context will be hidden.

* fftools/ffmpeg: move some muxing-related code into a separate fileAnton Khirnov2022-04-13
| | | | | This is a first step towards making muxers more independent from the rest of the code.
* fftools/ffmpeg: store the output file index in OutputFileAnton Khirnov2022-04-13
| | | | | Use it to simplify check_init_output_file(). Will allow further simplifications in the following commits.
* fftools/ffmpeg: pass the muxer context explicitly to some functionsAnton Khirnov2022-04-13
| | | | | Stop accessing OutputFile.ctx. This will be useful in the following commits, where it will become hidden.
* fftools/ffmpeg: stop using OutputStream.frame_number for streamcopyAnton Khirnov2022-04-13
| | | | | | | | | | | | | | This field is currently used by checks - skipping packets before the first keyframe - skipping packets before start time to test whether any packets have been output already. But since frame_number is incremented after the bitstream filters are applied (which may involve delay), this use is incorrect. The keyframe check works around this by adding an extra flag, the start-time check does not. Simplify both checks by replacing the seen_kf flag with a flag tracking whether any packets have been output by do_streamcopy().

* avformat: Add IPFS protocol support.Mark Gaiser2022-04-12
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for: - ffplay ipfs://<cid> - ffplay ipns://<cid> IPFS data can be played from so called "ipfs gateways". A gateway is essentially a webserver that gives access to the distributed IPFS network. This protocol support (ipfs and ipns) therefore translates ipfs:// and ipns:// to a http:// url. This resulting url is then handled by the http protocol. It could also be https depending on the gateway provided. To use this protocol, a gateway must be provided. If you do nothing it will try to find it in your $HOME/.ipfs/gateway file. The ways to set it manually are: 1. Define a -gateway <url> to the gateway. 2. Define $IPFS_GATEWAY with the full http link to the gateway. 3. Define $IPFS_PATH and point it to the IPFS data path. 4. Have IPFS running in your local user folder (under $HOME/.ipfs).
