* avcodec/bsf: ff_list_bsf staticAndreas Rheinhardt2021-09-08
| | | | | | | | It is a special BSF that is only available via the av_bsf_list-API; it is not part of the list generated from the declarations in bitstream_filters.c and therefore needn't have external linkage. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | It is supposed to be used with different bit depth and/or sample rates per each substream, but such currently not implemented feature is not important and current state causes problems when implementing variable restart interval to fix decoding with sample rates not multiple of 40.

* avcodec/omx: Check initializing mutexes/conditionsAndreas Rheinhardt2021-09-04
| | | | | | | | | | | | | The earlier code did not properly check these initializations: It only recorded whether the part of init where these initializations are has been reached, but it did not check whether the initializations were successful, although destroying them would be undefined behaviour if they had not been initialized successfully. Furthermore cleanup() always locked a mutex regardless of whether there was any attempt to initialize these mutexes at all.

* avcodec/vp9: Remove vp9_free_entries()Andreas Rheinhardt2021-09-04
| | | | | | | | | | | Now that the mutexes and conditions are only initialized and destroyed once, said function only had one purpose: free the entries array. Given that vp9_alloc_entries() already does this if the array is already allocated it is unnecessary to call vp9_free_entries() anywhere except when closing. And then one can just inline the one free into vp9_decode_free(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vp9: Use av_freep() instead of av_free()Andreas Rheinhardt2021-09-04
| | | | | | | | Otherwise the context would be in an inconsistent state if vp9_alloc_entries() failed (and if this would be checked). Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

| | | | | | | | We have more mutexes/condition variables whose initialization is unchecked. Also use a proper namespace for these functions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/vp9: Do not destroy uninitialized mutexes/conditionsAndreas Rheinhardt2021-09-04
| | | | | | | | | | | | | | | | Also do not destroy and reinitialize mutexes and conditions when certain input parameters change. Given that the decoder did not create these variables at all during init, uninitialized mutexes and conditions are destroyed before the very first initialization. This is undefined behaviour and certain threading implementations like pthreadGC2 crash when it is attempted. Fix this by initializing these objects once during init and freeing them in close.

* avcodec/h264_levels, h265_profile_level: Avoid relocationsAndreas Rheinhardt2021-09-04
| | | | | | | | | | | | | | H.264 and H.265 levels' names are usually of the form "x" or "x.y" with x and y being single digits; the one exception are the H.264 1b levels. All of those levels' names fit into a char[4] and it is likely that this future levels will do so, too. Therefore this commit changes the H26(4|5)LevelDescriptor structures to use such a char [4] instead of a pointer to a const char. This makes the structures smaller (when sizeof(char*) == 8) and avoids relocations, thereby moving the corresponding arrays from .data.rel.ro into .rodata.
