* avcodec/bsf: make sure the AVBSFInternal stored packet is reference countedJames Almer2018-03-23
| | | | | | | | | | | | | | | | | | Some bitstream filters may buffer said packet in their own contexts for latter use. The documentation for av_bsf_send_packet() doesn't forbid feeding it non-reference counted packets, which depending on the way said packets were internally buffered by the bsf it may result in the data described in them becoming invalid or unavailable at any time. This was the case with vp9_superframe after commit e1bc3f4396, which was then promptly fixed in 37f4a093f7 and 7a02b364b6. It is still the case even today with vp9_reorder_raw. With this change the bitstream filters will not have to worry how to store or consume the packets fed to them. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: James Almer <jamrial@gmail.com>

* cbs_h264: Fix overflow in shiftsMark Thompson2018-03-18
| | | | | | | | | The type of the result of a shift operation is unaffected by the type of the right operand, so some existing code overflows with undefined behaviour when the element length is 32.

* 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.
