#1970: ffserver ignores ffmpeg command line arguments ------------------------------------+------------------------------------ Reporter: importinis | Type: defect Status: new | Priority: critical Component: FFserver | Version: 1.0 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ------------------------------------+------------------------------------ I'm trying to transcode from mpegts to flv. In mpegts are 2 audio streams but I want to transcode just one, and igore the other. http://pastebin.com/EMu5WS7Z please notice, that there is 2 examples: 1. ffmpeg writes to file - audio stream mapping works great. 2. ffserver ignores audio stream specified by ffmpeg and transcodes first one, not specified. The problem: ffserver ignores ffmpeg arguments! In this example it's obvious that ignores -map argument, but if I specify video filters - ffserver ignores as well. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1970> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1925(undetermined:new): Transcoding mjpeg video results in a very short frame

#1925: Transcoding mjpeg video results in a very short frame -------------------------------------+------------------------------------- Reporter: mbradshaw | Owner: Type: defect | Status: new Priority: normal | Component: Version: git- | undetermined master | Keywords: Blocked By: | Blocking: Reproduced by developer: 0 | Analyzed by developer: 0 -------------------------------------+------------------------------------- '''Summary of the bug:''' I have a mjpeg video I've created using libav*. The video plays fine in QuickTime, VLC, ffplay, etc. However, when I transcode the mjpeg video using FFmpeg, the first frame goes from a duration of 1.315918 seconds to just a fraction of a second. This happens on every mjpeg file I've tested that I create using libav*. I've tried FFmpeg 1.0 and current git head; results are the same. I suppose it's possible I'm generating the mjpeg wrong, but it plays fine in everything I've tried (QuickTime, VLC, ffplay, etc.) with no warnings or errors, FFmpeg gives no errors or warnings when transcoding, and I've inspected the frames with ffprobe and I can't see anything wrong with the mjpeg. '''How to reproduce:''' Using the following command, the output file (mpg.mpg) has a short first frame and doesn't match the source mjpeg (mjpeg.mov). I have attached both files. {{{ $ ffmpeg -i mjpeg.mov -vcodec mpeg2video -acodec mp2 -r 24 -bufsize 4000000 -maxrate 5000000 mpg.mpg ffmpeg version 1.0 Copyright (c) 2000-2012 the FFmpeg developers built on Nov 16 2012 15:00:58 with llvm-gcc 4.2.1 (LLVM build 2336.11.00) configuration: libavutil 51. 73.101 / 51. 73.101 libavcodec 54. 59.100 / 54. 59.100 libavformat 54. 29.104 / 54. 29.104 libavdevice 54. 2.101 / 54. 2.101 libavfilter 3. 17.100 / 3. 17.100 libswscale 2. 1.101 / 2. 1.101 libswresample 0. 15.100 / 0. 15.100 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7fb25b00f200] max_analyze_duration 5000000 reached at 5000272 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'mjpeg.mov': Metadata: major_brand : qt minor_version : 512 compatible_brands: qt encoder : Lavf54.29.104 Duration: 00:00:05.27, start: 0.000000, bitrate: 631 kb/s Stream #0:0(eng): Video: mjpeg (jpeg / 0x6765706A), yuvj420p, 1024x768, 536 kb/s, 1.02 fps, 4.58 tbr, 44100 tbn, 44100 tbc Metadata: handler_name : DataHandler Stream #0:1(eng): Audio: aac (mp4a / 0x6134706D), 44100 Hz, stereo, s16, 227 kb/s Metadata: handler_name : DataHandler Output #0, mpeg, to 'mpg.mpg': Metadata: major_brand : qt minor_version : 512 compatible_brands: qt encoder : Lavf54.29.104 Stream #0:0(eng): Video: mpeg2video, yuv420p, 1024x768, q=2-31, 200 kb/s, 90k tbn, 24 tbc Metadata: handler_name : DataHandler Stream #0:1(eng): Audio: mp2, 44100 Hz, stereo, s16, 128 kb/s Metadata: handler_name : DataHandler Stream mapping: Stream #0:0 -> #0:0 (mjpeg -> mpeg2video) Stream #0:1 -> #0:1 (aac -> mp2) Press [q] to stop, [?] for help frame= 95 fps=0.0 q=31.0 Lsize= 766kB time=00:00:05.27 bitrate=1189.9kbits/s dup=91 drop=0 video:678kB audio:82kB subtitle:0 global headers:0kB muxing overhead 0.751412% }}} In the files, the symbol clash should match with the start of each frame. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1925> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1398(undetermined:new): remuxed DTS audio won't play on hardware devices

#1398: remuxed DTS audio won't play on hardware devices -------------------------------------+------------------------------------- Reporter: patters | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: DTS audio | Blocked By: remux | Reproduced by developer: 0 Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- Hi, Firstly thanks for FFmpeg, it's an incredible tool. My interest in it comes from using the DLNA server Serviio which uses FFmpeg for its transcoding and remuxing. Many renderer devices don't support Matroska files but the streams they contain are often supported, so it's common to remux to mpeg-ts. I maintain the Serviio device profile for Sony Bluray and Network Media Players: http://forum.serviio.org/viewtopic.php?f=11&t=2004 I would like to report an issue with DTS audio streams that are remuxed into mpeg-ts by FFmpeg. The resulting files fail to play on many consumer electronics products which do officially support DTS, in my case Sony Bluray players, though I can see from the Serviio forum that it's also an issue for people who use AV receivers to decode the DTS stream. The files that FFmpeg produces play with silent audio on the affected devices, but they do play ok in VLC and Media Player Classic Home Cinema. I have observed this problem now for quite some time (maybe 18 months or so). I have reproduced this using the latest win32 build I could find from Zeranoe - ffmpeg-20120601-git-8a0efa9-win32-static.7z The remux command line that Serviio would issue is as follows: {{{ffmpeg -i "/volume1/public/video/Movies/The.Good.The.Bad.And.The.Ugly.EXTENDED.1966.BluRay.720p.DTS.x264-FSiHD.mkv" -y -async 1 -vcodec copy -vbsf h264_mp4toannexb -copyts -acodec copy -map 0:0 -map 0:1 -sn -f mpegts /volume1/@tmp/Serviio/transcoding- temp-1086-10-ORIGINAL.stf}}} The problem is not limited to my choice of example clip - I have found it to be consistent with all MKV files containing DTS audio. By contrast, the closed source utility [[http://www.videohelp.com/tools/tsMuxeR|tsMmuxeR]] is able to remux the same test clip in a way that plays perfectly on all systems I have tested. I shall attach 10MB clips of the original file, the FFmpeg non-working remux, and the TSmuxer working remux so that they may be analysed and compared. Hopefully this could lead to a fix, as it doesn't seem that this issue has been reported. Thanks, Patters -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1398> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

The specifications for the ffv1 header are here: http://ffmpeg.org/~michael/ffv1.html#toc-Subsection-4.3. If version >1 it may be useful to report the minor_version as well. At the moment I can't think of a reason to need to report things like coder_type and number of slices but it may be nice. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1534> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1157: Circular buffer overrun with 4+ ffmpeg instances. --------------------------------------+---------------------------------- Reporter: Involar | Type: defect Status: new | Priority: normal Component: undetermined | Version: 0.10.2 Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | --------------------------------------+---------------------------------- Hello, im trying to launch multiple transcoding instances on an i7 2600k. Now with 3 instaces everything is fine, but after 4th I get crashes with this error. CPU is at no more than 30% at the moment of crash. Memory ussage is about 500mb/4G. Here is the output. ffmpeg -i udp://@239.1.1.2:5000 -pass 1 -crf 5 -vcodec libx264 -preset ultrafast -g 20 -b 500k -bt 10k -acodec libfaac -ab 128k -ar 48000 -ac 2 -f mpegts udp://192.168.1.136:5004 -v warning -bufsize 10000 -vframes 10 [mpeg2video @ 0x249da20] mpeg_decode_postinit() failure Last message repeated 5 times [mpegts @ 0x24733a0] max_analyze_duration 5000000 reached at 5016000 [mpegts @ 0x24733a0] Estimating duration from bitrate, this may be inaccurate Please use -b:a or -b:v, -b is ambiguous [udp @ 0x24738e0] Circular buffer overrun.

Now I get it that my fifo buffer is too small to handle 4 instances. Can you please advise where can I change the initial value ?
