* avcodec/cbs: Fix potential overflowAndreas Rheinhardt2019-11-17
| | | | | | | | | | | | | The number of bits in a PutBitContext must fit into an int, yet nothing guaranteed the size argument cbs_write_unit_data() uses in init_put_bits() to be in the range 0..INT_MAX / 8. This has been changed. Furthermore, the check 8 * data_size > data_bit_start that there is data beyond the initial padding when writing mpeg2 or H.264/5 slices could also overflow, so divide it by 8 to get an equivalent check without this problem.

* avcodec/cbs: Factor out common code for writing unitsAndreas Rheinhardt2019-11-17
| | | | | | | | | | | | | | | | | All cbs-functions to write units share a common pattern: 1. They check whether they have a write buffer (that is used to store the unit's data until the needed size becomes known after writing the unit when a dedicated buffer will be allocated). 2. They use this buffer for a PutBitContext. 3. The (codec-specific) writing takes place through the PutBitContext. 4. The return value is checked. AVERROR(ENOSPC) here always indicates that the buffer was too small and leads to a reallocation of said buffer. 5. The final buffer will be allocated and the data copied. This commit factors this common code out in a single function in cbs.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avformat/flacdec: Remove useless packetAndreas Rheinhardt2019-11-17
| | | | | | | | | | | flac_read_timestamp() applied av_init_packet() to a packet (which initializes all fields of the packet except for data and size) and then went on to use only the data and size fields. In other words: Said packet can be removed and replaced by an uint8_t * and an int.

* avutil/eval: add function to track variable useGyan Doshi2019-11-17
| | | | | | | | | | | | | | | | | | | | | 1)Some filters allow cross-referenced expressions e.g. x=y+10. In such cases, filters evaluate expressions multiple times for successful evaluation of all expressions. If the expression for one or more variables contains a RNG, the result may vary across evaluation leading to inconsistent values across the cross-referenced expressions. 2)A related case is circular expressions e.g. x=y+10 and y=x+10 which cannot be succesfully resolved. 3)Certain filter variables may only be applicable in specific eval modes and lead to a failure of evaluation in other modes e.g. pts is only relevant for frame eval mode. At present, there is no reliable means to identify these occurrences and thus the error messages provided are broad or inaccurate. The helper function introduced - av_expr_count_vars - allows developers to identify the use and count of variables in expressions and thus tailor the error message, allow for a graceful fallback and/or decide evaluation order.

* avformat/av1dec: Redo flushing of bsfAndreas Rheinhardt2019-11-14
| | | | | | | | | | | | | | The current approach has two different calls to av_bsf_send_packet(): A normal one, sending a packet; and an extraordinary one just for flushing. These can be unified into one by making use of the newly documented fact that av_bsf_send_packet() allows to signal flushing via empty packets (i.e. packets without data and side-data). This also fixes CID 1455685 which resulted from the fact that the call for flushing was not checked given that it couldn't fail.

| | | | | | | | | | | | implementation. Explicitly allowing empty packets to signal flushing helps getting rid of special cases. It does not hinder the ability to send i.e. timing-only packets, because one can send packets with zero size and pkt->data set.
