Description

Hi,

with current git of ffmpeg i found that seeking in MXF stop working.

simple code:

av_seek_frame(fmt_ctx, -1, fmt_ctx->start_time, AVSEEK_FLAG_BACKWARD)

return *-1* with latest MXF, but returns with n2.6-dev-2073-g5440076 it returns *0*

source of test code attached, MXF file could be downloaded from http://downloads.m1stereo.tv/b7e45b6c33493f8f607803257426cbc5/

i did a double check of results and i am sure that call

av_seek_frame(fmt_ctx, -1, fmt_ctx->start_time, AVSEEK_FLAG_BACKWARD);

returns -1 for MXF with current version and 0 with ffmpeg version N-76817-g13834c1

moreover i did a ffmpeg program run like:

./ffmpeg -dump -loglevel debug -ss 0 -i r0.mxf -vframes 1 -y temp.jpg

and it works only with older version ffmpeg version N-72966-gcf11fd6:

From the log it seems the index may be broken.

Have you tried more recent firmwares from Omneon?

comment:6 by verem, 9 years ago

The file i tested against comes from Omneon samples (sometimes i assume them (files) as reference for testing)

But i did also a tests against MainconceptLogo_XDCAMHD_1920x1080_422.mxf that comes from http://downloads.mainconcept.com/MainConceptLogo_XDCAMHD_1920x1080_422.zip, the result is the same:

Another MXF XDCAM samples could be taken from http://hamburgpromedia.com/Testfiles/MXF_MPEG_Testfiles.php

av_seek_frame(XDcam_HD4221080i50.mxf)=-1

av_seek_frame(XDCAM_HD422_720p50.mxf)=-1

may be it is a good idea to collect such files for seek-testing regression

You are right, since the index table was changed to presentation order, seeking before the first keyframe does not work...

Mpeg video created by ffmpeg has no such problems, because they start with a keyframe in both presentation and storage order, but "real" XDCAM mxf files usually start with two B frames in presentation order...

I will send a patch soon to ffmpeg-devel which should fix this.
