* | avcodec/mediacodecdec: fix immediate EAGAIN with buffered packetAman Gupta2018-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In cases where the mediacodec decoder consumed a partial packet, receive_frame() would start returning EAGAIN if the rest of the packet couldn't be flushed and no frames were immediately available. This fixes receive_frame() to perform its normal blocking wait for new frames before returning EAGAIN. Fixes an issue I could reproduce fairly often on a FireOS 6 device, and reported to be happening intermittently by two mpv users.

* | vc2enc: properly promote operations to 64 bitsRostislav Pehlivanov2018-03-13
| | | | | | | | | | | | | | | | | | | | | | On Windows machines, the UL suffix still means 32 bits. The only parts that need 64 bits are (1ULL << (m + 32)) and (t*qf + qf). Hence, use the proper ULL suffix for the former and just increase the type of the qf constant for the latter. No overflows can happen as long as these are done in 64 bits and the quantization table doesn't change. Signed-off-by: Rostislav Pehlivanov <atomnuker@gmail.com>

* | avcodec/mediacodecdec: add debug logging around hw buffer lifecycleAman Gupta2018-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | Some Android devices are very finicky about how quicky output buffers are returned back to the decoder, especially when they are associated with a Surface. This commit adds a new counter that keeps track of exactly how many hw output buffers are being retained by the user, along with DEBUG level logging that makes it easy to track the lifecycle of these buffers.

* | lavc/videotoolbox: fix threaded decodingRodger Combs2018-03-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AVHWAccel.end_frame can run on a worker thread. The assumption of the frame threading code is that the worker thread will change the AVFrame image data, not the AVFrame fields. So the AVFrame fields are not synced back to the main thread. But this breaks videotoolbox due to its special requirements (everything else is fine). It actually wants to update AVFrame fields. The actual videotoolbox frame is now stored in the dummy AVBufferRef, so it mimics what happens in non-videotoolbox cases. (Changing the AVBufferRef contents is a bit like changing the image data.) The post_process callback copies that reference to the proper AVFrame field. Based on a patch by wm4. Signed-off-by: Aman Gupta <aman@tmm1.net>

* | avcodec/mediacodecdec: add delay_flush optionAman Gupta2018-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default behavior of the mediacodec decoder before this commit was to delay flushes until all pending hardware frames were returned to the decoder. This was useful for certain types of applications, but was unexpected behavior for others. The new default behavior with this commit is now to execute flushes immediately to invalidate all pending frames. The old behavior can be enabled by setting delay_flush=1. With the new behavior, video players implementing seek can simply call flush on the decoder without having to worry about whether they have one or more mediacodec frames still buffered in their rendering pipeline. Previously, all these frames had to be explictly freed (or rendered) before the seek/flush would execute. The new behavior matches the behavior of all other lavc decoders, reducing the amount of special casing required when using the mediacodec decoder.

* | lavc/qsvenc: disable h264 look_ahead by defaultZhong Li2018-03-06
| | | | | | | | | | | | | | | | | | | | | | Look_ahead can provide quality improvements, but would better disable it by default due to some reasons: 1. It is only available for some codecs (e.g. HEVC is not supported) on Intel Haswell and plus platforms. Thus means it will be failed on some platforms. 2. It significantly increases encoding latency and memory consumption. 3. It may overwrite some other options such as CBR and CAVLC.
