The patch will make audio and subtitle packets be marked as AV_PKT_FLAG_KEY. For audio, it'll caused the audio sample to be sync sample. To verify ref/fate/movenc results: 1. Get the movenc test data [lmwang@vpn ffmpeg]$ libavformat/tests/movenc -w && mkdir -p audio_old && mv *.mp4 audio_old_ After applied the patch: [lmwang@vpn ffmpeg]$ make fate-movenc SAMPLES=../fate-suite [lmwang@vpn ffmpeg]$ libavformat/tests/movenc -w && mkdir -p audio_key && mv *.mp4 audio_key 2.

Failures of the allocations that happen under the hood when using dynamic buffers are usually completely unchecked and the Matroska muxer is no exception to this. The API has its part in this, because there is no documented way to actually check for errors: The return value of both avio_get_dyn_buf() as well as avio_close_dyn_buf() is only documented as "the length of the byte buffer", so that using this to return errors would be an API break. Therefore this commit uses the only reliable way to check for errors with avio_get_dyn_buf(): The AVIOContext's error flag. (This is one of the advantages of avio_get_dyn_buf(): By not destroying the AVIOContext it is possible to inspect this value.) Checking whether the size or the pointer vanishes is not enough as it does not check for truncated output (the dynamic buffer API is int based and so has to truncate the buffer even when enough memory would be available; it's current actual limit is even way below INT_MAX).

If one already has the contents of a master elements in a buffer of known size, then writing a EBML master element is no different from writing an EBML binary element. It is overtly complicated to use start/end_ebml_master() as these functions first write an unkown-length size field of the appropriate length, then write the buffer's contents, followed by a seek to the length field to overwrite it with the real size (obtained via avio_tell() although it was already known in advance), followed by another seek to the previous position. Just use put_ebml_binary() instead. Signed-off-by: -

There is a good upper bound for the maximum length of the Colour master element; it is therefore unnecessary to use a dynamic buffer for it. A simple buffer on the stack is enough. This commit implements this. Signed-off-by: -

The Matroska muxer updates several header elements when the output is seekable; if unseekable, the buffer containing the contents of the element is immediately freed after writing. Before this commit, there were three places doing exactly the same: Checking whether the output is seekable and calling the function that writes and frees or the function that just writes the EBML master. This has been unified; adding SeekHead entries for these elements has been unified, too. Signed-off-by: -
Andreas Rheinhardt authored
Up until now, SeekEntries were already added before start_ebml_master_crc32() was even called and before we were actually sure that we really write the element the SeekHead references: After all, we might also error out later; and given that the allocations implicit in dynamic buffers should be checked, end_ebml_master_crc32() will eventually have to return errors itself, so that it is the right place to add SeekHead entries. The earlier behaviour is of course a remnant of the time in which start_ebml_master_crc32() really did output something, so that the position before start_ebml_master_crc32() needed to be recorded. Erroring out later is also not as dangerous as it seems because in this case no SeekHead will be written (if it happened when writing the header, the whole muxing process would abort; if it happened when writing the trailer (when writing chapters not available initially), writing the trailer would be aborted and no SeekHead containing the bogus chapter entry would be written). This commit does not change the way the SeekEntries are added for those elements that are output preliminarily; this is so because the SeekHead is written before those elements are finally output and doing it otherwise would increase the amount of seeks.

The mapping of streams to the various variant streams to be created by the HLS muxer is roughly as follows: Space and tab separate variant stream group maps while the entries in each variant stream group map are separated by ','. The parsing process of each variant stream group proceeded as follows: At first the number of occurences of "a:", "v:" and "s:" in each variant stream group is calculated so that one can can allocate an array of streams with this number of entries. Then each entry is checked and the check for stream numbers was deficient: It did check that there is a number beginning after the ":", but it did not check that the number extends until the next "," (or until the end). This means that an invalid variant stream group like v:0_v:1 will not be rejected; the problem is that the variant stream in this example is supposed to have two streams associated with it (because it contains two "v:"), yet only one stream is actually associated with it (because there is no ',' to start a second stream specifier). This discrepancy led to segfaults (null pointer dereferencing) in the rest of the code (when the nonexistent second stream associated to the variant stream was inspected). Furthermore, this commit also removes an instance of using atoi() whose behaviour on a range error is undefined. Fixes ticket #8652. Signed-off-by: -

This patch adds possibility to use 'periodic-rekey' option with multi-variant streams to hlsenc muxer. All streams variants use parameters from the same key_info_file. There are 2 sets of encryption options that kind of overlaps and add complexity, so I tried to do the thing without changing too much code. There is a little duplication of the key_file, key_uri, iv_string, etc in the VariantStream since we copy it from hls to each variant stream, but generally all the code remains the same to minimise appearing of unexpected bugs. Refactoring could be done as a separate patch then as needed. Signed-off-by:Yaroslav Pogrebnyak <yyyaroslav@gmail.com>

and make it static again. These functions have been moved from nutenc to aviobuf and internal.h in f8280ff4 in order to use them in a forthcoming patch in utils.c. Said patch never happened, so this commit moves them back and makes them static, effectively reverting said commit as well as f8280ff4 (which added the ff-prefix to these functions). Reviewed-by:

NUT uses variable-length integers in order to for length fields. Therefore the NUT muxer often writes data into a dynamic buffer in order to get the length of it, then writes the length field using the fewest amount of bytes needed. To do this, a new dynamic buffer was opened, used and freed for each element which involves lots of allocations. This commit changes this: The dynamic buffers are now resetted and reused.

With the description in frame size with refs semantics (SPEC 7.2.5), it is a requirement of bitstream conformance that for at least one reference frame has the valid dimensions. Modify the check to make sure the decoder works well in SINGLE_REFERENCE mode that not all reference frames have valid dimensions. Check and error out if invalid reference frame is used in inter_recon. One of the failure case is a 480x272 inter frame (SINGLE_REFERENCE mode) with following reference pool: 0. 960x544 LAST valid 1. 1920x1088 GOLDEN invalid, but not used in single reference mode 2. 1920x1088 ALTREF invalid, but not used in single reference mode 3~7 ...
