* avcodec/frame_thread_encoder: Avoid allocations of AVFramesAndreas Rheinhardt2021-02-16
| | | | | | | | | | | | | | | | Up until now, when using frame threaded encoding, an AVFrame would be allocated for every frame to be encoded. These AVFrames would reach the worker threads via a FIFO of tasks, a structure which contained the AVFrame as well as an index into an array which gives the place where the worker thread shall put the returned packet; in addition to that, said structure also contained several unused fields. This commit changes this: The AVFrames are now allocated during init in the array that is up until now only used to return the packets. The contents to be encoded are put into the AVFrame in the same array element that is also used to return the packets. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/frame_thread_encoder: Avoid allocations of AVPackets, fix deadlockAndreas Rheinhardt2021-02-16
| | | | | | | | | | | | | | | | | | | | | Up until now, when doing frame thread encoding, each worker thread tried to allocate an AVPacket for every AVFrame to be encoded; said packets would then be handed back to the main thread, where the content of said packet is copied into the packet actually destined for output; the temporary AVPacket is then freed. Besides being wasteful this also has another problem: There is a risk of deadlock, namely if no AVPacket can be allocated at all. The user doesn't get an error at all in this case and the worker threads will simply try to allocate a packet again and again. If the user has supplied enough frames, the user's thread will block until a task has been completed, which just doesn't happen if no packet can ever be allocated. This patch instead modifies the code to allocate the packets during init; they are then reused again and again. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/frame_thread_encoder: Fix segfault on allocation errorAndreas Rheinhardt2021-02-16
| | | | | | | | | | | Fixes a segfault from av_fifo_size(NULL) that happens in ff_frame_thread_encoder_free if the fifo couldn't be allocted; furthermore the mutexes and conditions that are destroyed in ff_frame_thread_encoder_free are not even initialized at this point, so don't call said function.

* avcodec/hevcdec: check that the local context list was allocated before ↵James Almer2021-02-11
| | | | | | | | | | | | | | | | | | | dereferencing it Since the decoder is not flagged as init cleanup capable, hevc_decode_free() is being called manually if the hevc_decode_extradata() call fails at the end of hevc_decode_init(). In a frame threading scenario, however, if AVCodec->init() returns an error, ff_frame_thread_free() will be called regardless of the above flag being set or not, resulting in hevc_decode_free() being called a second time for the same context. Workaround this by ensuring pointers are not dereferenced if they are NULL, and set the decoder as init cleanup capable while at it. Fixes ticket #9099. Signed-off-by: James Almer <jamrial@gmail.com>

* mjpegdec: stop setting the QP tableAnton Khirnov2021-02-08

* avcodec/ac3enc: Share options and defaultsAndreas Rheinhardt2021-02-07
| | | | | | | | | | Both AC-3 encoder share the same options, yet they are nevertheless duplicated in the binary; and the options applying to the EAC-3 encoder are a proper subset of the options for the AC-3 encoders, so that it can use the same options as the former by putting the options specific to AC-3 at the front.

* avcodec/aacdec_fixed: Move fixed-point sinewin tables to its only userAndreas Rheinhardt2021-02-07
| | | | | | | | | | | | | | | | | | | | | | The fixed-point AAC decoder is the only user of the fixed-point sinewin tables from sinewin; and it only uses a few of them (about 10% when counting by size). This means that guarding initializing these tables by an AVOnce (as done in 3719122065863f701026632f610175980d42b05a) is unnecessary for them. Furthermore the array of pointers to the individual arrays is also unneeded. Therefore this commit moves these tables directly into aacdec_fixed.c; this is done by ridding the original sinewin.h and sinewin_tablegen.h headers completely of any fixed-point code at the cost of a bit of duplicated code (the alternative is an ugly ifdef-mess). This saves about 58KB from the binary when using hardcoded tables (as these tables are hardcoded in this scenario); when not using hardcoded tables, most of these savings only affect the .bss segment, but the rest (< 1KB) contains relocations (i.e. savings in .data.rel.ro).
