Can't use latest NASM with FFmpeg?

Hello, Since compiling x264.git requires NASM 2.13 now, I thought; let's try to use it to compile FFmpeg as well. The FFmpeg builds I made this far used Cygwin's NASM. Here's an excerpt from 'ffbuild/config.log': /cygdrive/m/ffmpeg-windows-build-helpers-master/native_build/windows/ffmpeg_local_builds/sandbox/cross_compilers/mingw-w64-i686/bin/i686-w64-mingw32-gcc -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -U__STRICT_ANSI__ -D__USE_MINGW_ANSI_STDIO=1 -D__printf__=__gnu_printf__ -D_WIN32_WINNT=0x0600 -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600 -march=pentium3 -O2 -mfpmath=sse -msse -DCACA_STATIC -DLIBTWOLAME_STATIC -march=pentium3 -O2 -mfpmath=sse -msse -std=c11 -fomit-frame-pointer -c -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.c nasm -v NASM version 2.10.05 compiled on Sep 11 2012 check_x86asm movbe ecx, [5] BEGIN /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S 1 movbe ecx, [5] END /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S nasm -Werror -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S check_x86asm vmovdqa32 [eax]{k1}{z}, zmm0 BEGIN /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S 1 vmovdqa32 [eax]{k1}{z}, zmm0 END /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S nasm -f win32 -DPREFIX -Werror -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S:1: error: parser: instruction expected check_x86asm vextracti128 xmm0, ymm0, 0 BEGIN /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S 1 vextracti128 xmm0, ymm0, 0 END /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S nasm -f win32 -DPREFIX -Werror -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S check_x86asm vpmacsdd xmm0, xmm1, xmm2, xmm3 BEGIN /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S 1 vpmacsdd xmm0, xmm1, xmm2, xmm3 END /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S nasm -f win32 -DPREFIX -Werror -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S check_x86asm vfmaddps ymm0, ymm1, ymm2, ymm3 BEGIN /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S 1 vfmaddps ymm0, ymm1, ymm2, ymm3 END /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S nasm -f win32 -DPREFIX -Werror -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S check_x86asm CPU amdnop BEGIN /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S 1 CPU amdnop END /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S nasm -f win32 -DPREFIX -Werror -o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.o /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S /cygdrive/c/DOCUME~1/Admin/LOCALS~1/Temp/ffconf.NvmIZN9O/test.S:1: error: unknown 'cpu' type check_code cc arm_neon.h int16x8_t test = vdupq_n_s16(0) check_cc ---------------------------------------------------------------- No problem whatsoever.

Is there any approach to tell ffmpeg how to determine dts of fMP4 segment?
by toya3329 01 Mar '18

01 Mar '18

Hi, all! Does anyone known that when handling fMP4 segment dts timestampe, is there any approach to tell ffmpeg how to determine dts of fMP4 segment? (otherwise you have to rebuild all stuffs :<) The current choosing preference always make some fMP4 segments (with sidx earliest_presentation_time 0) to have the incorrect dts time stamp (0), although it was caused by an incorrect arliest_presentation_time. TIA -- Sent from: http://www.ffmpeg-archive.org/

Why _COPYing_ a variable encoded audio (AAC) channel will produce a variably encoded one?
by Sophoklis Goumas 01 Mar '18

01 Mar '18

Hello. I have a .3gp file containing a video and an audio channel. I'm trying to get the audio channel in a separate m4a file but when I issue: ffmpeg -i foo.3gp -vn -c:a copy foo.m4a I get a constantly encoded AAC audio channel while the original was a variably encoded one. In more detail, from this: Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : mp4a-40-2 Bit rate mode : Variable Bit rate : 32.0 kb/s Maximum bit rate : 34.4 kb/s Channel(s) : 1 channel Channel positions : Front: C Sampling rate : 22.05 kHz Frame rate : 21.533 FPS (1024 SPF) Compression mode : Lossy Stream size : 82.4 MiB (60%) I end up with this: Format : AAC Format/Info : Advanced Audio Codec Format profile : LC Codec ID : mp4a-40-2 Bit rate mode : Constant Bit rate : 32.0 kb/s Channel(s) : 2 channels Channel(s)_Original : 1 channel Channel positions : Front: C Sampling rate : 22.05 kHz Frame rate : 21.533 FPS (1024 SPF) Compression mode : Lossy Stream size : 82.4 MiB (98%) Default : Yes Alternate group : 1 Thanks in advance, Sophoklis

NVDEC/NVENC resources underutilization
by Garri Djavadyan 28 Feb '18

28 Feb '18

Hello FFmpeg community, I faced a problem with NVDEC/NVENC resources underutilization while running one ffmpeg instance. We use ffmpeg to convert various format videos to MP4(h264/aac) and applying logo overlay. Hardware decoding and encoding process is performed by NVDEC and NVENC chips. For example, our cmdline is: /usr/local/ffmpeg-dev/bin/ffmpeg -y -c:v mpeg4_cuvid \ -i input.avi -i logo.png \ -filter_complex [0:v:0][1:v:0]overlay=10:10[out1] \ -map [out1] -map 0:a:0 -map_metadata -1 -map_chapters -1 \ -c:v h264_nvenc -b:v 1024k -r 25 \ -c:a libfdk_aac -b:a 128k \ -movflags faststart out.mp4 The overal transcoding process is greatly accelerated. But I see, that NVDEC/NVENC cycles are not fully utilized. For example: # nvidia-smi dmon # gpu pwr temp sm mem enc dec mclk pclk # Idx W C % % % % MHz MHz 0 32 50 11 3 22 16 3802 1632 0 32 50 11 3 23 14 3802 1632 0 32 50 12 3 22 15 3802 1632 0 33 51 13 3 18 15 3802 1632 0 32 51 12 3 17 11 3802 1632 0 32 51 10 2 20 13 3802 1632 I tried to find a bottleneck, but all system resources are OK.

Fisheye-equirectangular in real time
by Edward Bellamy 28 Feb '18

28 Feb '18

Hi, I am looking for a way to convert my fisheye video to equirectsangular in realtime or as low latency as possible. I was thinking about using ffmpeg with 2 SDI capture cards for input and output and using the remap filter to relight the pixels, Do you have any experience with a build like this? Is it possible to do input and output via SDI? How do i get this running as low latency as possible? Kind regards Edward Bellamy | Creative & Technical Director AU +61 476 100 722 http://www.staplesvr.com <http://www.staplesvr.com.au/>
