[06:18] <cone-788> ffmpeg.git 03Michael Niedermayer 07master:754f84663e8b: avcodec/msrle: check return code for success before use
[13:34] <nevcairiel> is there an easy way to scan an assembled function if it uses instructions of a certain simd function set? ie. I want to verify a sse function doesn't accidentally use sse2 functions
[13:53] <J_Darnley> I don't know an existing solution but...
[13:54] <J_Darnley> you could grep a plain-text dump of the instructions for certain instructions

[16:57] <cone-625> ffmpeg.git 03Vladlen Y. Koshelev 07master:cdbd9e218d44: avformat/hls: support for seeking on event playlists
[17:14] <nevcairiel> so I finally found the offending instruction, and my disasm claims its a movq .. is movq sse2?
[17:14] <nevcairiel> 6A2F2851  movq        mmword ptr [eax+ecx],xmm2  
[17:14] <nevcairiel> specifically
[18:25] <cone-625> ffmpeg.git 03Michael Niedermayer 07master:28f8114bd240: avcodec/vp8: fix checking vp7_feature_value_size
[18:25] <cone-625> ffmpeg.git 03Michael Niedermayer 07master:c1b24ca762cb: avformat/oggdec: check for av_packet_new_side_data() failure
[18:25] <cone-625> ffmpeg.git 03Michael Niedermayer 07master:4ccd7cb45b9a: avformat/oggdec/ogg_read_packet(): factorize failure code path
[18:28] <michaelni> nevcairiel, movq with xmm should be sse2
[18:28] <nevcairiel> it appears so
[18:28] <michaelni> 0x6a is a push though not a movq
[18:29] <nevcairiel> thats just the binary offset
[18:29] <nevcairiel> not the instruction
[18:29] <michaelni> ahh ok thought it was intended to be the intrsuctions bytes
[18:33] <nevcairiel> I sent a patch to the ML to correct it
[18:44] <cone-625> ffmpeg.git 03Hendrik Leppkes 07master:fc7e02f0ff34: dcadsp: fix SSE code to not use SSE2 instructions.
[19:29] <ubitux> why isn't movq defined on movh for avx2?
[19:30] <ubitux> (since movq xm0, blah seems to work)
[19:31] <ubitux> (it translates to vmovq)
[19:34] <ubitux> mmh i guess that's because movh means "half" and thus for ymm it would mean dq
[19:38] <ubitux> i don't get why movdq[au] (or mov[au]) would be 256 load with ymm though
[19:40] <cone-625> ffmpeg.git 03Reimar Döffinger 07master:57d10a28f41b: pulseaudio: move NULL check up before dereference.
[19:47] <ubitux> side note: today libav decides to NIH fontconfig support in drawtext, with a different configure option ofc
[19:49] Action: ubitux wonders if the answer will be "i'm not following all our downstreams"
[19:49] <nevcairiel> of course it will be
[19:49] <nevcairiel> its a handy excuse
[20:01] <kierank> ubitux: that was why i moved to ffmpeg
[20:01] <kierank> drawtext and friends
[20:30] <BBB> nevcairiel: I've used qemu for that in the past
[20:30] <BBB> nevcairiel: that actually worked
[20:30] <BBB> nevcairiel: but it's a little ... clunky
[20:32] <BBB> nevcairiel: also if move is all there is, see has an analog for that and I think x86inc.asm knows it?
[22:05] <cone-625> ffmpeg.git 03Reimar Döffinger 07master:a0568ed25440: rtspdec: check for strchr returning NULL.

[23:46] <J_D> Wow, someone went on a lucasarts bender.
[23:47] <nevcairiel> fwiw, those existed in ffmpeg for quire a while already
[23:56] <cone-625> ffmpeg.git 03Paul B Mahol 07master:a027d2a8731f: fate: add tests for SANM and VIMA
