Convert them to zigzag order, as the rest of them are. When I was adding support for 10-bit DNxHD, I just copy-pasted the missing quant matrices from the spec. Now it turns out the existing matrices in dnxhddata.c were in zigzag order. This resulted in wrong quantization for 10-bit DNxHD. The attached patch fixes the problem by converting 10-bit quant matrices to zigzag order. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Freeze picture release should be set to 1 when we're responding to a fast update request. For simplicity we set it for all intra frames, including those that starts a GOP. Fixes issue where Tandberg MXP1700 does not recover from packet loss state since it's waiting for the freeze picture relase indication.

Ref H.261 recommendation section 4.2.1.3, setting the still image flag to 1 disables still image mode. Some decoders require this in order to decode the bitstream as normal video. Fixes H.261 calls to Cisco E20. Also, reserved (aka spare) bits should be set to 1 unless specified otherwise. Bug-Id: 872 CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

Do not fall back on the codec timebase, since that can be anything for VFR video.

The encoder uses almost none of the mpegvideo infrastructure, only some fields from MpegEncContext. The FATE results change because now an all-zero quant matrix is written into the file. Since it is not used for anything for ljpeg, this should not be a problem.

QuickTime will play multiple audio tracks concurrently if this flag is set for multiple audio tracks. And if no subtitle track has this flag set, QuickTime will show no subtitles in the subtitle menu. Signed-off-by: Anton Khirnov <anton@khirnov.net>

This allows us to remove FF_IDCT_WMV2, which serves no practical purpose other than to be able to select the WMV2 IDCT for MPEG (or vice versa) and get corrupt output. Fate tests for all wmv2-related tests change, because (for some obscure reason) they forced use of the MPEG IDCT. You would get the same changes previously by not using -idct simple in the fate test (or replacing it with -idct auto).
