* lavfi/dnn: DNNAsyncExecModule Execution Failure HandlingShubhanshu Saxena2021-08-10
| | | | | | | | | This commit adds the case handling if the asynchronous execution of a request fails by checking the exit status of the thread when joining before starting another execution. On failure, it does the cleanup as well. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* lavfi/dnn_backend_tf: Error Handling for tf_create_inference_requestShubhanshu Saxena2021-08-10
| | | | | | | This commit includes the check for the case when the newly created TFInferRequest is NULL. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* lavfi/dnn: Extract Common Parts from get_output functionsShubhanshu Saxena2021-08-10
| | | | | | | | The frame allocation and filling the TaskItem with execution parameters is common in the three backends. This commit shifts this logic to dnn_backend_common. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* lavfi/dnn_backend_tf: Add TF_Status to TFRequestItemShubhanshu Saxena2021-08-10
| | | | | | | | | Since requests are running in parallel, there is inconsistency in the status of the execution. To resolve it, we avoid using mutex as it would result in single TF_Session running at a time. So add TF_Status to the TFRequestItem Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* lavfi/dnn_backend_tf: Error Handling for execute_model_tfShubhanshu Saxena2021-08-10
| | | | | | | | This patch adds error handling for cases where the execute_model_tf fails, clears the used memory in the TFRequestItem and finally pushes it back to the request queue. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>
* lavfi/dnn: Async Support for TensorFlow BackendShubhanshu Saxena2021-08-10
| | | | | | | | | | | | | | | | | | | This commit enables async execution in the TensorFlow backend and adds function to flush extra frames. The async execution mechanism executes the TFInferRequests on a separate thread which is joined before the next execution of same TFRequestItem/while freeing the model. The following is the comparison of this mechanism with the existing sync mechanism on TensorFlow C API 2.5 CPU variant. Async Mode: 4m32.846s Sync Mode: 5m17.582s The above was performed on super resolution filter using SRCNN model. Signed-off-by: Shubhanshu Saxena <shubhanshu.e01@gmail.com>

* lavfi/dnn: Add Async Execution Mechanism and DocumentationShubhanshu Saxena2021-08-10

* lavfi/qsvvpp: do not mix up FFmpeg and SDK error codeHaihao Xiang2021-08-09
| | | | | | | | The function ff_qsvvpp_filter_frame should return a FFmpeg error code if there is an error. However it might return a SDK error code without this patch. Reviewed-by: Soft Works <softworkz@hotmail.com>
* avfilter/asrc_flite: Don't define an object by accidentAndreas Rheinhardt2021-08-08

* avfilter/vf_vif: Fix mismatch in number of array elementsAndreas Rheinhardt2021-08-08
| | | | | | | | | | | The function definition used float *data_buf[14], although there are only 13 elements (and only 13 are used); the declaration used 13. Given that the type will be converted to float **data_buf anyway, this is not in violation of the C specs, but nevertheless a bug. GCC 11 has a new warning for this -Warray-parameter.

| | | | | | | | | | | | | 8b83dad82512a6948b63408f964463b063ad24c9 added another potentially used video enhancement filter without increasing a define for the number of such options which is used as the size of stack array. This can lead to a buffer overrun if all filters are used simultaneously. So increase said number. Fixes Coverity ticket #1489775.

| | | | | | | | | | | | | | | | | | | | | | | | The magic constants come from the unofficial "ITU-R BS.1770-1 filter specifications"¹ by Raiden (libebur128) which relies on "Parameter Quantization in Direct-Form Recursive Audio Filters"² by Brian Neunaber. The constants seem to include a quantization bias, for example: - Vb is supposed to be exactly √Vh in a high shelf filter - the Pre-filter Gain should likely be 4dB - Pre Q and RLB Q are respectively very close to √½ and ½ Those are not adjusted to prevent the values from drifting away from the official specifications. An alternative to this approach would be to requantize on the fly as proposed by pbelkner³, where the 48kHz code path would use the exact specifications constants while derivating constants for other frequencies.
