Dear all, Thank you for making the awesome software ffmpeg.
I am not subscribed to the archives so please CC me in case somebody answers it one way or the other. I usually find it takes quite some time when trying to partially trancode/copy a file. I am concerned with the startup time. It takes anywhere between 3-5 minutes before transcoding/copying starts. Something like https://paste.debian.net/1059975/ I find it takes quite a bit of time for the copy to be there. Is there anyway to make the process a bit faster, some sort of flag or something ? I am asking due to the cpu capabilities given - [libx264 @ 0x55ab4aa24380] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX FMA3 BMI2 AVX2 There might be some more things which could help perhaps - from inxi - CPU: Topology: Quad Core model: Intel Core i5-7400 bits: 64 type: MCP arch: Kaby Lake rev: 9 L1 cache: 256 KiB L2 cache: 6144 KiB L3 cache: 6144 KiB bogomips: 24000 Speed: 800 MHz min/max: 800/3300 MHz Core speeds (MHz): 1: 800 2: 800 3: 800 4: 800 Flags: 3dnowprefetch abm acpi adx aes aperfmperf apic arat arch_perfmon art avx avx2 bmi1 bmi2 bts clflush clflushopt cmov constant_tsc cpuid cpuid_fault cx16 cx8 de ds_cpl dtes64 dtherm dts ept ept_ad erms est f16c flexpriority flush_l1d fma fpu fsgsbase fxsr ht hwp hwp_act_window hwp_epp hwp_notify ibpb ibrs ida intel_pt invpcid invpcid_single lahf_lm lm mca mce mmx monitor movbe mpx msr mtrr nonstop_tsc nopl nx pae pat pbe pcid pclmulqdq pdcm pdpe1gb pebs pge pln pni popcnt pse pse36 pti pts rdrand rdseed rdtscp rep_good sdbg sep smap smep ss ssbd sse sse2 sse4_1 sse4_2 ssse3 stibp syscall tm tm2 tpr_shadow tsc tsc_adjust tsc_deadline_timer tsc_known_freq vme vmx vnmi vpid x2apic xgetbv1 xsave xsavec xsaveopt xsaves xtopology xtpr Graphics: Device-1: Intel HD Graphics 630 vendor: ASUSTeK driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:5912 Display: server: X.Org 1.20.3 driver: modesetting unloaded: fbdev,vesa resolution: 1600x900~60Hz OpenGL: renderer: Mesa DRI Intel HD Graphics 630 (Kaby Lake GT2) v: 4.5 Mesa 18.2.8 compat-v: 3.0 direct render: Yes It's a desktop machine having 8 GB RAM. Look forward to know if any hack or something can be done to make it a bit faster, or if there are any settings I can experiment with. -- Regards, Shirish Agarwal शिरीष अग्रवाल My quotes in this email licensed under CC 3.0 http://creativecommons.org/licenses/by-nc/3.0/ http://flossexperiences.wordpress.com EB80 462B 08E1 A0DE A73A 2C2F 9F3D C7A4 E1C4 D2D8 _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
