* libavformat/mux: Fix audio_preloadAndreas Rheinhardt2019-06-26
| | | | | | | | | | | | | | | | | Commit 31f9032b added the audio_preload feature; its goal is to interleave audio earlier than the rest. Unfortunately, it has never ever worked, because the check for whether a packet should be interleaved before or after another packet was completely wrong: When audio_preload vanishes, interleave_compare_dts returns 1 if the new packet should be interleaved earlier than the packet it is compared with and that is what the rest of the code expects. But the codepath used when audio_preload is set does the opposite. Also fixes potential undefined behaviour (namely signed integer overflow).

* avformat/matroskadec: Improve error/EOF checks IIIAndreas Rheinhardt2019-06-24
| | | | | | | | | | | Up until now, when an element was skipped, it was relied upon ffio_limit to make sure that there is enough data available to skip. ffio_limit itself relies upon the availability of the file's size. As this needn't be available, the check has been refined: First one byte less than intended is skipped, then another byte is read, followed by a check of the error flags.

* avformat/matroskadec: Improve read error/EOF checks IIAndreas Rheinhardt2019-06-24
| | | | | | | | | | | | | | | | | This commit fixes a number of bugs: 1. There was no check that no read error/EOF occured during ebml_read_uint, ebml_read_sint and ebml_read_float. 2. ebml_read_ascii and ebml_read_binary did sometimes not forward error codes; instead they simply returned AVERROR(EIO). 3. In particular, AVERROR_EOF hasn't been used and no dedicated error message for it existed. This has been changed. In order to reduce code duplication, the new error code NEEDS_CHECKING has been introduced which makes ebml_parse check the AVIOContext's status for errors.

* avformat/matroskadec: Improve read error/EOF checks IAndreas Rheinhardt2019-06-24
| | | | | | | | | | | | | | | | | | | | ebml_read_num had a number of flaws: 1. The check for read errors/EOF was totally wrong. E.g. an EBML number beginning with the invalid 0x00 would be considered a read error, although it is just invalid data. 2. The check for read errors/EOF was done just once, after reading the first byte of the EBML number. But errors/EOF can happen inbetween, of course, and this wasn't checked. 3. There was no way to distinguish when EOF should be an error (because the data has to be there) for which an error message should be emitted and when it is not necessarily an error (namely during parsing of EBML IDs). Such a possibility has been added and used. All this was fixed; furthermore, the error messages for invalid EBML numbers were improved and useless initializations were removed.

* configure: print_in_columns: Replace pr with awkAlexander Strasser2019-06-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Get rid of pr dependency and write the columns strictly alphabetical without page size considerations (POSIX specifies 66 lines as default). Setting the page size via pr's -l option was considered, but as there is issue #5680 which wants to avoid pr mainly because it's not in busybox, we chose to replace pr instead. Before pr would attempt to write pages, thus if a page boundary was reached, the output looked confusing as one couldn't see there was a new page and the alphabetical order was disrupted when scanning down one of the columns. This change is based on a shell implementation submitted before by Yejun. Possible differences to the current version using pr: 1. pr implementations should truncate items to not overflow columns; depending on how it's done not truncating shall be better IMHO. 2. pr implementations might balance columns differently; we use minimum number of lines and might end up not using all columns or might have lesser entries in the last column(s) 3. we use spaces only for padding the columns; at least the GNU pr version on my system also by default stuffs in tabs in addition to a single space in between columns. I don't see that this behaviour is demanded by POSIX, though I might be very well overlooking things. Anyway for our use case I can't see a need for having the additional tabs, or why it would be better compared to padding with spaces only. Fixes output for sizes with width < column width, too. Fixes remaining part of ticket #5680 Contributor: Guo, Yejun <yejun.guo@intel.com>
* avformat/hlsenc: better error log message for var_stream_map contentBela Bodecs2019-06-24
| | | | | | | | | | | | When multiple variant streams are specified by var_stream_map option, %v is expected either in the filename or in the last sub-directory name, but only in one of them. When both of them contains %v string, current error message only states half of the truth. And even %v may appears several times inside the last sub-directory name or in filename pattern. This patch clarifies this in the log message and in the doc also. Signed-off-by: Bela Bodecs <bodecsb@vivanet.hu>
* avformat/matroskadec: Treat SimpleBlock as EBML_BINAndreas Rheinhardt2019-06-23
| | | | | | | | | | | | | | | Up until now, the SimpleBlock was treated specially: It basically had its own EBML category and it was also included in the BlockGroup EBML syntax (although a SimpleBlock must not exist in a BlockGroup according to the Matroska specifications). The latter fact also meant that a MatroskaBlock's buffer was always unreferenced twice. This has been changed: The type of a SimpleBlock is now an EBML_BIN. The only way in which SimpleBlocks are still different is that they share their associated structure with another unit (namely BlockGroup). This is also used to unref the block: It is always unreferenced via the BlockGroup syntax. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avformat/matroskadec: Don't keep old blocksAndreas Rheinhardt2019-06-23
| | | | | | | | | | Before this commit, the Matroska muxer would read a block when required to do so, parse the block, create and return the necessary AVPackets and yet keep the blocks (in a dynamically allocated list), although they aren't used at all any more.

* avformat/matroskadec: Remove redundant initializationAndreas Rheinhardt2019-06-23
| | | | | | | | | Every new element of an EbmlList is zeroed initially in ebml_parse_elem, so that in particular a SimpleBlock's duration is initialized to zero.

* avformat/matroskadec: Set offset of first clusterAndreas Rheinhardt2019-06-23
| | | | | | | | | | | | | | | | | By default, the data_offset member of the AVFormatInternal of the AVFormatContext associated with the MatroskaDemuxContext has not been initialized explicitly by any Matroska-specific function, so that it was initialized by default to the offset at the end of matroska_read_header, i.e. usually to the offset of the length field of the first encountered cluster. This meant that in case that the Matroska-specific seek-code fails because there are no index entries for the target track a seek to data_offset would be performed and ordinary parsing would start from there which is nonsense: The length field would be treated as EBML ID and (if the length field is not longer than four bytes (EBML numbers that long are rejected as invalid EBML IDs)) whatever comes next would be treated as its EBML size although it simply isn't.
