Andreas Rheinhardt	d53acf452f	avformat/matroskaenc: Don't write \0 unnecessarily Writing the duration SimpleTag is special: It's size is reserved in advance via an EBML Void element (if seekable) and this reserved space is overwritten when writing the trailer; it does not use put_ebml_string(). The string to write is created via snprintf on a buffer of size 20; this buffer is then written via put_ebml_binary() with a size of 20. EBML strings need not be zero-terminated; if not, they are implicitly terminated by the element's length field. snprintf() always zero-terminates the buffer, i.e. the last byte can be discarded when using an EBML string. This patch does this. The FATE changes are as expected: One byte saved for every track; the only exception is the matroska-qt-mode test: An additional byte is saved because an additional byte could be saved from the enclosing Tags length field.

Andreas Rheinhardt	b468ddc75d	avformat/matroskaenc: Don't waste bytes to Write Tag length fields This is possible by using a dynamic buffer to write them; said dynamic buffer is (re)used and reset as appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	cb592ae95f	avformat/matroskaenc: Remove duplicated code for writing WebVTT subs Up until now, the WebM variant of WebVTT subtitles has been handled specially: It had its own function to write it, because the data had to be reformatted before writing. But given that other codecs also need reformatting, this is no good reason to also duplicate the generic stuff for writing Block(Group)s. This commit therefore uses an ordinary reformatting function for this task; writing WebVTT subtitles now uses the generic code and therefore automatically uses the least amount of bytes for its BlockGroup length fields whereas the earlier code used an overestimation for the length of the Duration element. This is the reason for the changes to the webm-webvtt-remux FATE-test. (This commit does not implement support for Matroska's way of muxing WebVTT; it also does not add checks to ensure that WebM-style subtitles don't get muxed in Matroska. But the function for reformatting gets a webm prefix to indicate that this is for WebM.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
James Almer	a42d249c91	avformat/framecrcenc: print basic side data information again This partially reverts `c6ae560a18`. Signed-off-by: James Almer <jamrial@gmail.com>	4 years ago
Anton Khirnov	c6ae560a18	lavf/framecrcenc: do not hash side data There are no guarantees that all side data types have the same representation on all platforms. Tests that change output due to this: id3v2-priv-remux, cover-art-mp3-id3v2-remux, gapless-mp3: SKIP_SAMPLES, which is tested by fate-gapless-mp3-side-data matroska-vp8-alpha-remux: MATROSKA_BLOCKADDITIONAL, which is tested by remux itself (side data is written into output) matroska-mastering-display-metadata: MASTERING_DISPLAY_METADATA and CONTENT_LIGHT_LEVEL, which are tested by ffprobe invocation in the same test matroska-spherical-mono-remux: STEREO3D and SPHERICAL, which are tested by ffprobe invocation in the same test segment-mp4-to-ts: MPEGTS_STREAM_ID, which is tested by ts remuxing tests webm-webvtt-remux: WEBVTT_IDENTIFIER/SETTINGS, which is tested by the ffprobe invocation in the same test mxf-d10-user-comments: CPB_PROPERTIES, which is tested by mxf-probe-d10 mov-cover-image: SKIP_SAMPLES, which is tested for mov by mov-aac-2048-priming copy-trac3074: AUDIO_SERVICE_TYPE, which is tested by fate-hls-fmp4_ac3	4 years ago

Andreas Rheinhardt	d4575982f4	tests/matroska: Add test for WebVTT in WebM Specifically test that the WebVTT flavour is correctly mapped to the Matroska/WebM CodecID and back; and test that dispositions unsupported by WebM are discarded even when they would be supported by Matroska.
