* avc_utils: skip empty NALs from malformed bistreamsRobert Shih2017-03-221-1/+4
| | | | | | | | | | | | | | | Avoid a CHECK and make it the decoder's repsonsibility to handle a malformed bistream gracefully. Bug: 34509901 Bug: 33137046 Test: StagefrightTest#testStagefright_bug_27855419_CVE_2016_2463 CVE-2017-0483 Change-Id: I2d94f8da63d65a86a9c711c45546e4c695e0f3b4 (cherry picked from commit 91fe76a157847825601b8f7a627efd1c9cbadcae) (cherry picked from commit 5cabe32a59f9be1e913b6a07a23d4cfa55e3fb2f)
* Stagefright: use set buffers mode.Shivaprasad Hongal2015-10-261-4/+14

* Stagefright: avc_utils: handle invalid sample aspect ratioPraveen Chavan2015-10-061-1/+1
| | | | | | | | | Set sample aspect ratio width & height only if both sar_width and sar_height are valid ( >1 ). sar-height being 0 can cause divide by zero exception in NuPlayer. Change-Id: Idfc4cae57651f3b5fd755057a880503f359aa004 CRs-Fixed: 735506

* Fix calculations for an obscure combo of MPEG audio options.John Grossman2012-09-061-2/+3
| | | | | | | | | | | | | | | MPEGv2 and MPEGv2.5 Layer 2 audio payloads should 1152 samples per access unit, not 576. Adjust the frame size and samples out calculations accordingly. Also, adjust the max frame size in the MP3Extractor's MediaSource to be closer to the theoretical worst case max frame size. The theoretical worst case for MPEG audio is 2881 bytes per frame, but the max frame size being used was 32kB. It has been changed to be 4kB in order to remain a power of 2 allocation, but to be the power of 2 closest to the worst case. Change-Id: If11f5a843b06e70151bbe8298cc54f954938d9d7
