Trying to build ffmpeg 8.1.2 requires fPIC

Hello, I'm trying to compile ffmpeg 8.1.2 on Devuan (Debian) Linux. I got the dependencies together. When trying to compile it, I'm getting error's saying that I need to pass -fPIC. I tried setting -fPIC in the CFLAGS and CXXFLAGS. I set --enable-pic in the configure options. But I still get the error. Here's an example: /usr/bin/ld: /usr/local/lib/libaribcaption.a(renderer_capi.cpp.o): warning: relocation against `_ZSt7nothrow@@GLIBCXX_3.4' in read-only section `.text' /usr/bin/ld: /usr/local/lib/libaribcaption.a(caption_capi.cpp.o): relocation R_X86_64_PC32 against symbol `_ZSt7nothrow@@GLIBCXX_3.4' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: final link failed: bad value collect2: error: ld returned 1 exit status make: *** [ffbuild/library.mak:136: libavcodec/libavcodec.so.62] Error 1 I also tried omitting -fPIC in the CFLAGS and CXXFLAGS (which are set to -O2 -march=native.) # nice -n19 make -j1 ... LDXX libswscale/libswscale.so.9 lto-wrapper: warning: using serial compilation of 12 LTRANS jobs lto-wrapper: note: see the -flto option documentation for more information /usr/bin/ld: /tmp/cc45MPxC.ltrans8.ltrans.o: relocation R_X86_64_32S against `.text.unlikely' can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: failed to set dynamic section sizes: bad value collect2: error: ld returned 1 exit status make: *** [ffbuild/library.mak:136: libswscale/libswscale.so.9] Error 1 I'm really lost as to what could be going wrong here. I even see -fPIC pop-up on htop while the compile job is running. Any idea how to pass fPIC or avoid having to do so? Thanks! PS: If you need the full config log and the configure command I can attach them. They're quite long.

HLS keepalive: too many requests (take 2)

Hi, [apologies if my previous message about this came through; I thought mistakenly that I was subscribed to the list!] I regularly stream videos using FFmpeg-based players (QMPlay2 & mpv) from a site that FFmpeg doesn't handle too politely, as suggested by the flow of errors like these: ``` > ffmpeg8 -hide_banner -fflags +igndts -i "https://URL/1080p.m3u8?OPTS" -y -acodec copy -vcodec copy /tmp/kk.mp4 |& fgrep -v "Invalid timestamps" mime type is not rfc8216 compliant [in#0 @ 0xfa27700] Opening 'https://URL/1080p/mkugvdY.ts?OPTS' for reading [in#0 @ 0xfa27700] Opening 'https://URL/1080p/nVvlYSee9v.ts?OPTS' for reading Input #0, hls, from 'https://URL/1080p.m3u8?OPTS': Duration: 00:59:46.42, start: 0.111111, bitrate: 0 kb/s Program 0 Metadata: variant_bitrate : 0 Stream #0:0[0x0]: Audio: aac (LC) ([15][0][0][0] / 0x000F), 44100 Hz, stereo, fltp, start 0.111111 Metadata: variant_bitrate : 0 Stream #0:1[0x0]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, start 0.111111 Metadata: variant_bitrate : 0 Stream mapping: Stream #0:1 -> #0:0 (copy) Stream #0:0 -> #0:1 (copy) Output #0, mp4, to '/tmp/kk.mp4': Metadata: encoder : Lavf62.12.102 Stream #0:0: Video: h264 (High) (avc1 / 0x31637661), yuv420p, 1920x1080 [SAR 1:1 DAR 16:9], q=2-31, 23.98 fps, 23.98 tbr, 90k tbn Metadata: variant_bitrate : 0 Stream #0:1: Audio: aac (LC) (mp4a / 0x6134706D), 44100 Hz, stereo, fltp Metadata: variant_bitrate : 0 Press [q] to stop, [?] for help [https @ 0x10205ec0] Opening 'https://URL/1080p/k1AaLmI1mja.ts?OPTS' for reading [https @ 0x1032a7c0] Opening 'https://URL/1080p/QW7Rw5sqKYe.ts?OPTS' for reading [https @ 0x10205ec0] Opening 'https://URL/1080p/2rOMJ9hOnny.ts?OPTS' for reading [https @ 0x1032a7c0] Opening 'https://URL/1080p/gZGKg8SWWrW.ts?OPTS' for reading [https @ 0x10205ec0] Opening 'https://URL/1080p/1amwzASa8jj.ts?OPTS' for reading [https @ 0x1032a7c0] Opening 'https://URL/1080p/4OP94MUqx18.ts?OPTS' for reading [https @ 0x10205ec0] Opening 'https://URL/1080p/73aXlPI2405.ts?OPTS' for reading [https @ 0x1032a7c0] Opening 'https://URL/1080p/qylqMGhzRV5.ts?OPTS' for reading [https @ 0x10205ec0] Opening 'https://URL/1080p/rx2W8gh4AKQ.ts?OPTS' for reading [https @ 0x10374f00] HTTP error 429 Too Many Requests [in#0/hls @ 0xfa27700] keepalive request failed for 'https://URL/1080p/rx2W8gh4AKQ.ts?OPTS' with error: 'Server returned 429 Too Many Requests' when opening url, retrying with new connection [in#0/hls @ 0xfa27700] Opening 'https://URL/1080p/rx2W8gh4AKQ.ts?OPTS' for reading [https @ 0x1032a7c0] Opening 'https://URL/1080p/nMOqgMiL718.ts?OPTS' for reading [https @ 0x1009dec0] HTTP error 429 Too Many Requests [in#0/hls @ 0xfa27700] keepalive request failed for 'https://URL/1080p/nMOqgMiL718.ts?OPTS' with error: 'Server returned 429 Too Many Requests' when opening url, retrying with new connection [in#0/hls @ 0xfa27700] Opening 'https://URL/1080p/nMOqgMiL718.ts?OPTS' for reading [https @ 0x7fc0900769c0] HTTP error 429 Too Many Requests [in#0/hls @ 0xfa27700] Failed to open segment 11 of playlist 0 [in#0/hls @ 0xfa27700] Opening 'https://URL/1080p/nMOqgMiL718.ts?OPTS' for reading [https @ 0x7fc090016580] HTTP error 429 Too Many Requests.89 bitrate=3489.9kbits/s speed=30.9x elapsed=0:00:02.00 [in#0/hls @ 0xfa27700] Failed to open segment 11 of playlist 0 [in#0/hls @ 0xfa27700] Opening 'https://URL/1080p/nMOqgMiL718.ts?OPTS' for reading [https @ 0x7fc090009dc0] Opening 'https://URL/1080p/3boXZnswVo1.ts?OPTS' for reading [https @ 0x7fc090071480] Opening 'https://URL/1080p/nbjo9MuaWrw1.ts?OPTS' for reading [https @ 0x7fc090009dc0] Opening 'https://URL/1080p/jrK6x8IVyyL.ts?OPTS' for reading [https @ 0x7fc090009980] HTTP error 429 Too Many Requests [in#0/hls @ 0xfa27700] keepalive request failed for 'https://URL/1080p/jrK6x8IVyyL.ts?OPTS' with error: 'Server returned 429 Too Many Requests' when opening url, retrying with new connection [in#0/hls @ 0xfa27700] Opening 'https://URL/1080p/jrK6x8IVyyL.ts?OPTS ``` To date I haven't seen these on other sites, and I cannot easily share streaming links because they're specific to my IP address. I remember trying to understand the HLS streaming code a while back and getting the impression that it does have some mechanism to adapt or otherwise modify the request interval, but I can't seem to find that now. What options are there to avoid this situation? Thanks, R.

Why Silero-VAD that is state-sponsored Russian software exist in this codebase?
by Yehor Smoliakov 06 Jul '26

06 Jul '26

I am writing to bring a concern to your attention regarding an issue identified in the whisper.cpp repository (Issue #3930, link - https://github.com/ggml-org/whisper.cpp/issues/3930) Upon reviewing the current implementation, I would like to seek clarification from the FFmpeg maintainers regarding the use of software that is Russian state-sponsored. Given the architectural standards of the project, could you please explain why this specific software is being utilized and whether this aligns with your security and ethical guidelines?
