#3187(undetermined:new): Please add SFD muxing

#3187: Please add SFD muxing -------------------------------------+------------------------------------- Reporter: Soukyuu | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: git- Keywords: | master Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Greetings. I am part of a fan project which attempts to fix the broken localization of the Ar tonelico 2 game. The official Western localization was sloppy and introduced game breaking bugs, which even made the game hang up on a boss encounter. Those are things our project is attempting to fix. Part of it involves adding translations to the videos in form of subtitles (the game includes both the English and the Japanese voice tracks). There is a tool floating around the net which allows to mux m1v+adx, but none which would allow muxing m1v+adx+ac3 into sfd. Having fixed almost everything except for the 5.1 opening sequence (which was left completely untranslated in the Western versions), I'd really appreciate if FFMPEG added sfd muxing functionality. The patch will require people to have already have a copy of the game as it will be distributed as .xdelta for the iso only. There are other games which use cri's adx/sofdec package, so it wouldn't only be for this single game, but for us, this is the main reason at the moment. (On another note, thanks for fixing the demuxing bug so fast) I can provide samples if needed. -- Ticket URL: <https://trac.ffmpeg.org/ticket/3187> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#2935: .nsv at the end of the URL hang ffmpeg. -------------------------------------+------------------------------------- Reporter: kasper93 | Type: defect Status: new | Priority: minor Component: | Version: git- undetermined | master Keywords: nsv | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: FFmpeg is trying to read .nsv form URL forever, without timeout or anything. Problem is with URLs like this one `http://antywawamp3-01.eurozet.pl:8600/;stream.nsv` it's common to found stream link with `;stream.nsv` at the end. FFmpeg works fine with `http://antywawamp3-01.eurozet.pl:8600/`. So either URL should be trim after '`;`' by ffmpeg. And one more thing is that FFmpeg shouldn't hang when it gets wrong .nsv stream.

#3128: cavs silently ignores garbage data ------------------------------------+-------------------------------------- Reporter: Timothy_Gu | Type: defect Status: new | Priority: normal Component: avcodec | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ------------------------------------+-------------------------------------- Summary of the bug: I generated some junk from /dev/urandom and fed it to cavs, and it just silently ignores the junk and outputed no frame. It should at least split out some error messages.

#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
