John Stebbins	b50173a4dd	movenc: fix QT chapter track character encoding An encoding ("encd") box is required to tell QT that the string is UTF8	11 years ago
John Stebbins	da9cc22d5b	movenc: add track title to tracks	11 years ago
John Stebbins	d9432789bd	movenc: remove pointless loop around BITEXACT test	11 years ago
John Stebbins	0897d2fdc7	movenc: Add option to disable nero chapters And add flag to muxer documentation. Nero chapters break some taggers (mp3tag and iTunes). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Luca Barbato	df2aa22203	mov: Clarify tkhd flag settings	11 years ago
Luca Barbato	f90729699d	mov: Do not group tracks if more than one is enabled per type The specification requires at most 1 track enabled per alternate group.	11 years ago
Anton Khirnov	194be1f43e	lavf: switch to AVStream.time_base as the hint for the muxer timebase Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).	11 years ago
Anton Khirnov	cf6977712c	movenc: write avg_frame_rate as the framerate, not the codec timebase	11 years ago
Anton Khirnov	0ba5299a80	movenc: use the "encoder" metadata tag to write stsd Compressorname This mirrors the demuxer behaviour and avoids accessing AVCodecContext.codec, which should not be done in muxers.	11 years ago
Anton Khirnov	0c1959b056	lavf: add AVFMT_FLAG_BITEXACT. Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's codec context. Using codec options inside lavf is fragile and can easily break when the muxing codec context is not the encoding context.	11 years ago
Miles Gould	99e22b7859	mov: Emit the correct tags for clcp tracks Bug-Id: 664 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Aidan Skinner	802385dbc2	mov: Write prof section of tapt tag Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Diego Biurrun	cba4e6062a	More correct printf format specifiers This avoids compiler warnings about argument and specifier type mismatch.	11 years ago
Michael Niedermayer	f94371b1db	mov: Unbreak sbtl writing	11 years ago
John Stebbins	6adf3bc42e	movenc: Add dvd subtitle support Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago

John Stebbins	565e0c6d86	movenc: allow override of "writing application" tag Signed-off-by: Tim Walker <tdskywalker@gmail.com> CC: libav-stable@libav.org	11 years ago
Martin Storsjö	1e142d5b48	movenc: Add a fallback fragmentation method for plain mp4 as well Previously the default fragmentation method was only enabled if writing an ISM file. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	8f8bc92365	Add missing #includes for INT64_MAX and INT64_C	11 years ago
Clément Bœsch	e01fba5562	movenc: Add an F4V muxer F4V is Adobe's mp4/iso media variant, with the most significant addition/change being supporting other flash codecs than just aac/h264. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	f2b00a5372	movenc: Return a proper error code for invalid combinations Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	f1eac2b8a0	movenc: Use keyframes as default fragmentation point in ismv Fragmenting blindly to a certain duration isn't a good choice if one should be able to switch between different qualities, therefore default to keyframes instead. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	a9553bbb33	movenc: Set all implicit flags immediately in mov_write_header This makes sure other sanity checks for conflicting options can work properly, e.g. for the conflict between the faststart flag when using the ismv mode. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	187023f6b2	movenc: Set mov->mode earlier in mov_write_header This allows simplifying some early checks that depend on the muxer mode. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	72fe16a13e	movenc: Use null buffers for measuring the amount of data to be written Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	e7bf085b78	movenc: Add an option for omitting the tfhd base offset This makes the output fragments independent of their position in the output stream, making the output work better when streamed. QuickTime Player doesn't support fragmented mp4 without the base data offset, though. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	a4adabb460	movenc: Write the moof atom in two passes This is a bit more work, but avoids having to fill in the data offset field afterwards instead of directly when the rest of the trun atom is written. This simplifies future cases where this field needs to be set to something different. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	bdf990425e	movenc: Simplify setting the fragmentation flag This makes sure the faststart vs fragmentation check works as intended when fragmentation is enabled due to using the ismv mode. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	8b524ab0c4	movenc: Add a warning message if conflicting options have been specified Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	0fbda03e5c	movenc: Don't flush after each written packet This should improve write performance quite significantly. --- Tested with both writing a normal mp4, by using the faststart feature and writing a fragmented mp4 file; all turn out with the same md5sum as before. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	0fb3e1c6ce	movenc: Check for errors from mov_create_chapter_track On failures in the write_trailer function, we could also ignore the errors and try to finish the file despite these errors (which would only leave an incomplete chapters track). It's probably better to signal the error clearly to the caller though (and if this function failed there's no guarantee that there's enough memory to finish the trailer either).

Martin Storsjö	2bbad1f94c	movenc: Properly free allocated data on failures in mov_write_header Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Luca Barbato	b89e8759e0	mov: Write tmcd extradata	12 years ago
John Stebbins	30ce289074	movenc: Make tkhd "enabled" flag QuickTime compatible QuickTime will play multiple audio tracks concurrently if this flag is set for multiple audio tracks. And if no subtitle track has this flag set, QuickTime will show no subtitles in the subtitle menu. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Clément Bœsch	60198742ff	movenc: fix detection of 64bit offset requirement The old method doesn't work when moov is relocated to beginning of file Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
John Stebbins	fe5d5a8ffc	movenc: Make chapter track QuickTime compatible QuickTime requires that the stsd.text box be completely filled in. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Clément Bœsch	f8ef91ff3d	movenc: add faststart option for web streaming Faststart moves the moov atom to the beginning of the file and rewrites the rest of the file after muxing is complete. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
John Stebbins	6c786765cd	movenc: Allow chapters to be written in trailer This allows creation of frame accurate chapter marks from sources like DVD and BD where the precise chapter location is not known until the chapter mark has been reached during reading. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
John Stebbins	db03cb37fd	movenc: Allow chapter track in default MODE_MP4 Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Luca Barbato	67400f6b62	mov: Prevent segfaults on mov_write_hdlr_tag Do not segfault when writing tracks such as tmcd by writing them down as generic DataHandlers if not known.	12 years ago
Luca Barbato	22de0f8369	mov: Compute max duration among the tracks with a timescale Prevent an assert.	12 years ago
Luca Barbato	3952303010	mov: Set the timescale for data streams Data streams have a defined timebase, do not ignore it.	12 years ago
