#500(undetermined:new): Seemingly inconsistent AVIndexEntry timestamps for movs starting with B-Frames

#500: Seemingly inconsistent AVIndexEntry timestamps for movs starting with B-Frames -------------------------------------+------------------------------------- Reporter: rmk | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- A while ago I asked on the ml regarding the semantics of the undocumented fields of AVIndexEntry defined in avformat.h (http://www.mail-archive.com /libav-user(a)ffmpeg.org/msg00535.html) I didn't get an answer so I still do not know what the correct behaviour is but I have observed things that at least appear inconsistent. I have two examples of MPEG-2 files in a mov container which both start with the sequence BBI (presentation order). One is the file that is attached to issue #479 that has the following properties: Mesht0456_01_cut.MP4 AVStream.time_base = 1/30000 AVStream.start_time = 3003 (0.1001s) start frame order = BBI PTS of first I-Frame = 3003 PTS of first frame (B) = 0 first I-frame AVIndexEntry.timestamp = 0 Then another one (uploaded to http://www.datafilehost.com/download- 27d635cc.html since I do not have a smaller sample): xdcam_hd422_1080p24.mov AVStream.time_base = 1/2400 AVStream.start_time = 200 (0.08333333333333334s) start frame order = BBI PTS of first I-Frame = 200 PTS of first frame (B) = 0 first I-frame AVIndexEntry.timestamp = -100 (-0.416666666666667s) The first sample looks like AVIndexEntry.timestamp is set with the stream's start_time subtracted from the respective frame's PTS. This also works for all following index entries. However, this does not work for the second example. I have no idea if this is related to issue #479. All I'm trying to do is use the index (if it is there) to find out the PTSs of keyframes and I thought that was OK to do via AVIndexEntry. So either I am abusing the API and it would help to document this so others don't run into this or one of the files is broken or it is indeed a bug. In any case, just a short, unambiguous sentence of documentation for each AVIndexEntry field by someone who knows the semantics would help libav API users a great deal to use this and to help improve the seeking functionality of ffmpeg be it only by providing bug reports with samples. One more observation is that in both cases the timestamp of the index entry corresponding to the first I frame matches the DTS of the packet containing the I-Frame. Is that the semantics of AVIndexEntry.timestamp? In that case how would one derive the PTS of the I-frame from the index entry? Any insight/help would be greatly appreciated. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/500> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#551: Enhancements for ffmpeg 0.6.3 when dealing with live H264 stream ----------------------------------+--------------------------------------- Reporter: ilevin | Type: enhancement Status: new | Priority: minor Component: avformat | Version: unspecified Keywords: H264 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+--------------------------------------- Add abilities when writing to/reading from 3gp/mov format, and with no decoding/encoding (handling already encoding live stream from the net): 1. To store/retreive "btrt" bitrate box 2. Store/retreive "max NALU size" for H264 stream 3. Read "udta" box on a stream level -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/551> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
