Marth64	3525544e48	libavformat: add RCWT closed caption muxex Signed-off-by: Marth64 <marth64@proxyid.net> Raw Captions With Time (RCWT) is a format native to ccextractor, a commonly used open source tool for processing 608/708 closed caption (CC) sources. It can be used to archive the original, raw CC bitstream and to produce a source file file for later CC processing or conversion. As a result, it also allows for interopability with ccextractor for processing CC data extracted via ffmpeg. The format is simple to parse and can be used to retain all lines and variants of CC. A free specification of RCWT can be found here: https://github.com/CCExtractor/ccextractor/blob/master/docs/BINARY_FILE_FORMAT.TXT This muxer implements the specification as of 01/05/2024, which has been stable and unchanged for 10 years as of this writing. This muxer will have some nuances from the way that ccextractor muxes RCWT. No compatibility issues when processing the output with ccextractor have been observed as a result of this so far, but mileage may vary and outputs will not be a bit-exact match. Specifically, the differences are: (1) This muxer will identify as "FF" as the writing program identifier, so as to be honest about the output's origin. (2) ffmpeg's MPEG-1/2, H264, HEVC, etc. decoders extract closed captioning data differently than ccextractor from embedded SEI/user data. For example, DVD captioning bytes will be translated to ATSC A53 format. This allows ffmpeg to handle 608/708 in a consistant way downstream. This is a lossless conversion and the meaningful data is retained. (3) This muxer will not alter the extracted data except to remove invalid packets in between valid CC blocks. On the other hand, ccextractor will by default remove mid-stream padding, and add padding at the end of the stream (in order to convey the end time of the source video).	1 year ago

Zhao Zhili	2205ccd216	avformat/mpegtsenc: add omit_rai flag Add PCR at keyframe can be undesirable when -pcr_period is specified. Add an flag to disable this behavior. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 years ago
Lucy	1af3698296	avformat/hlsenc: Use HLS version 2 if rounded durations are enabled This allows for wider compatibility with older devices, such as those running iOS 3. The only difference between HLS version 2 and version 3 is that version 3 supports non-integer EXTINF values, and as such, we can default to version 2 if we're using whole-integer EXTINFs anyways, when `-hls_flags round_durations` is set. As this code seems to otherwise consistently use the lowest compatible version, this seems to fit in properly with existing behavior. Testing confirms with that this patch, HLS output can work all the way back to iOS 3. Reviewed-by: Steven Liu <liuqi05@kuaishou.com> Signed-off-by: Lucy <lucy@absolucy.moe>	3 years ago

Andreas Rheinhardt	99a4d16658	avformat/matroskaenc: Add option to shift data to write cues at front This is similar to the faststart option of the mov muxer, yet in contrast to it it works together with reserve_index_space (the equivalent to reserved_moov_size): If the reserved space does not suffice, the data is shifted; if not, the Cues are written at the front without shifting the data. Several tests that cover (not only) this have been added. Implements #7017. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Steven Liu	6cf55b9da2	avformat/hlsenc: deprecate hls_ts_options option Because the hls_ts_options will be misunderstand by user, and then user can use hls_segment_options instead of hls_ts_options. Signed-off-by: Steven Liu <liuqi05@kuaishou.com>	3 years ago
