* avformat/flac_picture: Simplify parsing titleAndreas Rheinhardt2021-08-28
| | | | | | | Don't allocate the buffer for the title ourselves, leave it to av_dict_set(). This simplifies freeing. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avformat/oggparsevorbis: Avoid tmp bufs when parsing VorbisCommentAndreas Rheinhardt2021-08-28
| | | | | | | | | | | | | | | | | | | | | | | | A single VorbisComment consists of a length field and a non-NUL-terminated string of the form "key=value". Up until now, when parsing such a VorbisComment, zero-terminated duplicates of key and value would be created. This is wasteful if these duplicates are freed shortly afterwards, as happens in particular in case of attached pictures: In this case value is base64 encoded and only needed to decode the actual data. Therefore this commit changes this: The buffer is temporarily modified so that both key and value are zero-terminated. Then the data is used in-place and restored to its original state afterwards. This requires that the buffer has at least one byte of padding. All buffers currently have AV_INPUT_BUFFER_PADDING_SIZE bytes padding, so this is ok. Finally, this also fixes weird behaviour from ogm_chapter(): It sometimes freed given to it, leaving the caller with dangling pointers.

* h274: remove optimization pragmaLynne2021-08-28
| | | | | | | | | | | | | | This results in warnings on compilers which don't support it, objections were raised during the review process about it but went unnoticed, and the speed benefit is highly compiler and version specific, and also not very critical. We generally hand-write assembly to optimize loops like that, rather than use compiler magic, and for 40% best case scenario, it's simply not worth it. Plus, tree vectorization is still problematic with GCC and disabled by default for a good reason, so enabling it locally is sketchy.

* lavfi/dnn: Rename InferenceItem to LastLevelTaskItemShubhanshu Saxena2021-08-28
| | | | | | | | | | | | | | | This patch renames the InferenceItem to LastLevelTaskItem in the three backends to avoid confusion among the meanings of these structs. The following are the renames done in this patch: 1. extract_inference_from_task -> extract_lltask_from_task 2. InferenceItem -> LastLevelTaskItem 3. inference_queue -> lltask_queue 4. inference -> lltask 5. inference_count -> lltask_count Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* libavfilter: Remove Async Flag from DNN Filter SideShubhanshu Saxena2021-08-28
| | | | | | | Remove async flag from filter's perspective after the unification of async and sync modes in the DNN backend. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* libavfilter: Remove synchronous functions from DNN filtersShubhanshu Saxena2021-08-28
| | | | | | | | This commit removes the unused sync mode specific code from the DNN filters since the sync and async mode are now unified from the filters' perspective. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* libavfilter: Unify Execution Modes in DNN FiltersShubhanshu Saxena2021-08-28
| | | | | | | | | | | | | | | | | | | | | | | This commit unifies the async and sync mode from the DNN filters' perspective. As of this commit, the Native backend only supports synchronous execution mode. Now the user can switch between async and sync mode by using the 'async' option in the backend_configs. The values can be 1 for async and 0 for sync mode of execution. This commit affects the following filters: 1. vf_dnn_classify 2. vf_dnn_detect 3. vf_dnn_processing 4. vf_sr 5. vf_derain This commit also updates the filters vf_dnn_detect and vf_dnn_classify to send only the input frame and send NULL as output frame instead of input frame to the DNN backends.

* avcodec/bsf: Avoid allocation for AVBSFInternalAndreas Rheinhardt2021-08-25
| | | | | | | | | | Do this by allocating AVBSFContext together with the data that is currently in AVBSFInternal; or rather: Put AVBSFContext at the beginning of a new structure called FFBSFContext (which encompasses more than just the internal fields and is a proper context in its own right, hence the name) and remove the AVBSFInternal altogether.

* avformat/avio: Move internal AVIOContext fields to avio_internal.hAndreas Rheinhardt2021-08-25
| | | | | | | | | | | | | | Currently AVIOContext's private fields are all over AVIOContext. This commit moves them into a new structure in avio_internal.h instead. Said structure contains the public AVIOContext as its first element in order to avoid having to allocate a separate AVIOContextInternal which is costly for those use cases where one just wants to access an already existing buffer via the AVIOContext-API. For these cases ffio_init_context() can't fail and always returned zero, which was typically not checked. Therefore it has been made to not return anything.

* arm: hevc_qpel: Fix the assembly to work with non-multiple of 8 widthsMartin Storsjö2021-08-25
| | | | | | | | | | | | | | | | | | | | This unbreaks the fate-checkasm-hevc_pel test on arm targets. The assembly assumed that the width passed to the DSP functions is a multiple of 8, while the checkasm test used other widths too. This wasn't noticed before, because the hevc_pel checkasm tests (that were added in 9c513edb7999a35ddcc6e3a8d984a96c8fb492a3 in January) weren't run as part of fate until in b492cacffd36ad4cb251ba1f13ac398318ee639a in August. As this hasn't been an issue in practice with actual full decoding tests, it seems like the actual decoder doesn't call these functions with such widths. Therefore, we could alternatively fix the test to only test things that the real decoder does, and this modification could be reverted. Signed-off-by: Martin Storsjö <martin@martin.st>
* tests/fate: move TTML-in-MP4 tests from subtitles.mak to mov.makJan Ekström2021-08-25
| | | | | | | | subtitles.mak's fate-sub tests utilize a more strict comparator ("rawdiff"), which causes the tests fail in case of white space differences, such as CRLF vs LF. This in turn causes these ffprobe-using TTML-in-MP4 tests to fail on non-LF systems such as Windows or wine.
