* avcodec/pixlet: fix architecture-dependent code and valuesVittorio Giovara2017-03-07
| | | | | | | | | | | | | The constants used in the decoder used floating point precision, and this caused different values to be generated on different architectures. So, eradicate floating point numbers and use fixed point (32.32) arithmetics everywhere, replacing constants with precomputed integer values.

* avcodec/h264, videotoolbox: fix crash after VT decoder failsAman Gupta2017-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The way videotoolbox hooks in as a hwaccel is pretty hacky. The VT decode API is not invoked until end_frame(), so alloc_frame() returns a dummy frame with a 1-byte buffer. When end_frame() is eventually called, the dummy buffer is replaced with the actual decoded data from VTDecompressionSessionDecodeFrame(). When the VT decoder fails, the frame returned to the h264 decoder from alloc_frame() remains invalid and should not be used. Before 9747219958060d8c4f697df62e7f172c2a77e6c7, it was accidentally being returned all the way up to the API user. After that commit, the dummy frame was unref'd so the user received an error. However, since that commit, VT hwaccel failures started causing random segfaults in the h264 decoder. This happened more often on iOS where the VT implementation is more likely to throw errors on bitstream anomolies. A recent report of this issue can be see in http://ffmpeg.org/pipermail/libav-user/2016-November/009831.html The issue here is that the dummy frame is still referenced internally by the h264 decoder, as part of the reflist and cur_pic_ptr. Deallocating the frame causes assertions like this one to trip later on during decoding: Assertion h->cur_pic_ptr->f->buf[0] failed at src/libavcodec/h264_slice.c:1340 With this commit, we leave the dummy 1-byte frame intact, but avoid returning it to the user. This reverts commit 9747219958060d8c4f697df62e7f172c2a77e6c7. Signed-off-by: wm4 <nfxjfg@googlemail.com>

* avcodec: consider an error during decoder draining as EOFwm42017-03-06
| | | | | | | | | | | | | | There is no reason that draining couldn't return an error or two. But some decoders don't handle this very well, and might always return an error. This can lead to API users getting into an infinite loop and burning CPU, because no progress is made and EOF is never returned. In fact, ffmpeg.c contains a hack against such a case. It is made unnecessary with this commit, and removed with the next one. (This particular error case seems to have been fixed since the hack was added, though.) This might lose frames if decoding returns errors during draining.

* avcodec/videotoolbox: allow not setting the kCVPixelBufferPixelFormatTypeKeywm42017-03-02
| | | | | | | | | | | If AVVideotoolboxContext.cv_pix_fmt_type is set to 0, don't set the kCVPixelBufferPixelFormatTypeKey value on the VT decoder. This makes VT output its native format, which can be much faster on some hardware iterations (if the native format does not match with the requested format, it will be converted, which is slow). The default is still forcing nv12.
