Le duodi 2 thermidor, an CCXXV, Michael Niedermayer a écrit :
breaks on mips (probably big endian issue)
Breaks on MIPS, or detects that something is already broken in MIPS and
nobody noticed until now?
this patch breaks the selftests on mips or maybe more precissely
it adds a test which fails
Could you perhaps re-run the test with V=1, then re-run the command line
with -f png, to see how the output is broken?
Stream #0:0: Video: rawvideo ([12][0]3Y / 0x5933000C), yuv444p12be, 320x240
[SAR 1:1 DAR 4:3], q=2-31, 13824 kb/s, 5 fps, 5 tbn, 5 tbc (default)
the format used seems the native one that has different endianness
and thus different checksums

i tried forcing le but it alone didnt give the same result
ive to sleep now so i cant look further into this today
but iam happy to test patches tomorrow, also iam just testing with
mips qemu not real hw so if it wasnt for the one time work to set
build env up and qemu than it would be rather easy for anyone to test
I tested the opposite direction by forcing yuv444p12be on x86-64 and
got different frame-CRCs "0xda6a937e" compared to the MIPS-CRCs you
posted earlier "0xba079be7". Not sure what is happening ...
mybe the le<->be
is the BE output you get identical to LE ? (besides the endianness)
Finally managed to setup a MIPS cross-compiler plus qemu. Looking at the
(verbose) log output of the command line indicates that the yuvtestsrc
filter output is configured to yuv444p instead of the assumed yuv444p12be :
$ qemu-mips -cpu 74Kf ./build-mips/ffmpeg-dbg -nostdin -nostats
-cpuflags all -lavfi "yuvtestsrc=rate=5:duration=1" -pix_fmt yuv444p12le
-flags +bitexact -fflags +bitexact -f framecrc - -loglevel verbose
[...]
[Parsed_yuvtestsrc_0 @ 0x1c99eb0] size:320x240 rate:5/1

[auto_scaler_0 @ 0x1c9a550] w:iw h:ih flags:'bilinear' interl:0
[format @ 0x1c9a380] auto-inserting filter 'auto_scaler_0' between the
filter 'Parsed_yuvtestsrc_0' and the filter 'format'
[auto_scaler_0 @ 0x1c9a550] w:320 h:240 fmt:yuv444p sar:1/1 -> w:320
h:240 fmt:yuv444p12le sar:1/1 flags:0x2
[...]
Not sure if this is "normal". After forcing the yuvtestsrc output to
(native) yuv444p12 the tests succeeds on both platforms:
CMD = framecrc -lavfi yuvtestsrc=rate=5:duration=1,format=yuv444p12
-pix_fmt yuv444p12le
Will post a patch update.

Tobias
