#512: libavutil\common.h conversion warnings ---------------------------------------+--------------------------------- Reporter: DonMoir | Owner: michael Type: enhancement | Status: new Priority: minor | Component: avutil Version: unspecified | Keywords: Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 ---------------------------------------+--------------------------------- Would you please make a couple minor changes to libavutil\common.h. static av_always_inline av_const int16_t av_clip_int16_c(int a) { if ((a+0x8000) & ~0xFFFF) return (a>>31) ^ 0x7FFF; else return a; } the returns cause me a conversion warning because they need to be cast to int16_t and so I have to change this each time I get a new include for ffmpeg. change to: static av_always_inline av_const int16_t av_clip_int16_c(int a) { if ((a+0x8000) & ~0xFFFF) return (int16_t)((a>>31) ^ 0x7FFF); else return (int16_t)a; } cast return values to (int32_t) for the following: static av_always_inline av_const int32_t av_clipl_int32_c(int64_t a) { if ((a+0x80000000u) & ~UINT64_C(0xFFFFFFFF)) return (a>>63) ^ 0x7FFFFFFF; else return a; } also for this one in libavutil\rational.h cast return values to (int): static inline int av_cmp_q(AVRational a, AVRational b){ const int64_t tmp= a.num * (int64_t)b.den - b.num * (int64_t)a.den; if(tmp) return (int)(((tmp ^ a.den ^ b.den)>>63)|1); else if(b.den && a.den) return 0; else if(a.num && b.num) return (int)((a.num>>31) - (b.num>>31)); else return INT_MIN; } There is no other case I have come across the produces any warnings but these. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/512> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

I believe it is related to the leading underscore _ before avdevice_register_all but I can't confirm that. I'm building for Windows and the toolchain is not the issue. I gave this a critical priority because FFmpeg will not build a shared version for Windows. I'm unsure of what patch broke this, but the last proven working build I know of is git-39dbe9b. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/282> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#933: A/V desynch when transcoding A/V files with timestamps non starting from 0 with -copyts -------------------------------------+------------------------------------- Reporter: saste | Owner: Type: defect | Status: new Priority: normal | Component: FFmpeg Version: git- | Keywords: timestamp master | desynch mpegts Blocked By: | Blocking: Reproduced by developer: 1 | Analyzed by developer: 0 -------------------------------------+------------------------------------- Using the command: {{{ ffmpeg -vsync 0 -copyts -i columbia-intro.ts -acodec libfaac -y columbia- intro.out.ts }}} (same without -vsync) the A/V streams in the output file result desynched, and will result in the video being unplayable. This seems due to the first audio packet timestamp information not being correctly propagated to the encoder (and to the muxer), and being set to 0, so that ffmpeg will fill the first part of the file with audio packets, and the probe will fail since ffmpeg can't detect video frames in the probed initial part of the file. Same result in case I use the -copyts with no -vsync. If the output file only contains video (e.g. if the -an switch is used) the output file seems to be correctly generated (playable and with correct timestamp information). I'm attaching a sample file and log obtained by adding debugging print in ffmpeg.c. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/933> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
