* libswcale/input: use more accurate planer rgb16 yuv conversionsMark Reid2020-10-06
| | | | | | | These conversion appears to be exhibiting the same rounding error as the rgbf32 formats where. I seperated the rounding value from the 16 and 128 offsets, I think it makes it a little more clear. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
* avformat/movenc: implement writing of the btrt boxJan Ekström2020-09-22
| | | | | | | | | | | This is utilized by various media ingests to figure out the bit rate of the content you are pushing towards it, so write it for video, audio and subtitle tracks in case at least one nonzero value is available. It is only mentioned for timed metadata sample descriptions in QTFF, so limit it only to ISOBMFF (MODE_MP4) mode. Updates the FATE tests which have their results changed due to the 20 extra bytes being written per track.
* avutil/timecode: fix av_timecode_get_smpte_from_framenum with 50/60 fpsMarton Balint2020-09-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SMPTE 12M timecode can only count frames up to 39, because the tens-of-frames value is stored in 2 bit. In order to resolve this 50/60 fps SMPTE timecode is using the field bit (which is the same bit as the phase correction bit) to signal the least significant bit of a 50/60 fps timecode. See SMPTE ST 12-1:2014 section 12.1. Therefore we slightly change the format of the return value of av_timecode_get_smpte_from_framenum and AV_FRAME_DATA_S12M_TIMECODE and start using the previously unused Phase Correction bit as Field bit. (As the SMPTE standard suggests) We add 50/60 fps support to av_timecode_get_smpte_from_framenum by calling the recently added av_timecode_get_smpte function in it which already handles this properly. This change affects the decklink indev and the DV and MXF muxers. MXF has no fate test for 50/60fps content, DV does, therefore the changes. MediaInfo (a recent version) confirms that half-frame timecode must be inserted to DV. MXFInspect confirms valid timecode insertion to the System Item of MXF files. For MXF, also see EBU R122. Note that for DV the field flag is not used because in the HDV specs (SMPTE 370M) it is still defined as biphase mark polarity correction flag. So it should not matter that the DV muxer overrides the field bit. Signed-off-by: Marton Balint <cus@passwd.hu>
* libavcodec/jpeg2000: fix tag tree resetGautam Ramakrishnan2020-08-30
| | | | | | | | | | The implementation of the tag tree did not set the correct reset value for the encoder. This lead to inefficent tag tree being encoded. This patch fixes the implementation of the ff_tag_tree_zero() function. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

The per layer compression ration can be set as follows: -layer_rates "r1,r2,...rn" for to create 'n' layers. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| * 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.

| * dnxhddata: Fix 10-bit DNxHD quant matricesJoseph Artsimovich2015-10-02
| | | | | | | | | | | | | | | | | | | | | | | | Convert them to zigzag order, as the rest of them are. When I was adding support for 10-bit DNxHD, I just copy-pasted the missing quant matrices from the spec. Now it turns out the existing matrices in dnxhddata.c were in zigzag order. This resulted in wrong quantization for 10-bit DNxHD. The attached patch fixes the problem by converting 10-bit quant matrices to zigzag order. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

The color table consists of an array of RGBQUAD values. The size of the array is given by the biClrUsed member. If biClrUsed is zero, the array contains the maximum number of colors for the given bitdepth; that is, 2^biBitCount colors." Nothing about "monochrome" here. Unfortunately, pal8 to monow conversion seems a bit flaky, but that's another story. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
