In testing we have now had multiple instances where the resulting files are treated as unplayable due to an incorrect syncSampleTable entry, either in our app, or in any QuickTime-based player. VLC will open the files, so they’re obviously close to correct, but we need it to work in our app, every time.</div><div class=""><br class=""></div><div class="">A typical error message is shown below, and media which exhibits the problem can be found here: <a href="https://dl.dropboxusercontent.com/u/16009858/AXISCamera2-20150617-123230.mov" class="">https://dl.dropboxusercontent.com/u/16009858/AXISCamera2-20150617-123230.mov</a></div><div class=""><br class=""></div><div class=""><span style="color: rgb(51, 51, 51); font-family: 'Helvetica Neue', Helvetica, 'Segoe UI', Arial, freesans, sans-serif; font-size: 14px; line-height: 22px; background-color: rgb(255, 255, 255);" class="">[11:21:23.991] CheckSyncSampleAtom signalled err=-12848 (kFigFormatReaderError_ParsingFailure) (syncSampleTable has an entry which is out of the range of 1 to numSamples, inclusive) at /SourceCache/CoreMedia/CoreMedia-1562.235/Prototypes/FormatHandlers/Movie/MovieAtomParsing.c line 1697</span><br style="box-sizing: border-box; color: rgb(51, 51, 51); font-family: 'Helvetica Neue', Helvetica, 'Segoe UI', Arial, freesans, sans-serif; font-size: 14px; line-height: 22px;" class=""><span style="color: rgb(51, 51, 51); font-family: 'Helvetica Neue', Helvetica, 'Segoe UI', Arial, freesans, sans-serif; font-size: 14px; line-height: 22px; background-color: rgb(255, 255, 255);" class=""><<< FFR_Movie >>> ParseTrackAtom: Omitting a track that encountered error -12848 during atom parsing</span></div><div class=""><span style="color: rgb(51, 51, 51); font-family: 'Helvetica Neue', Helvetica, 'Segoe UI', Arial, freesans, sans-serif; font-size: 14px; line-height: 22px; background-color: rgb(255, 255, 255);" class=""><br class=""></span></div><div class=""><font color="#333333" face="Helvetica Neue, Helvetica, Segoe UI, Arial, freesans, sans-serif" class=""><span style="background-color: rgb(255, 255, 255);" class=""><span style="font-size: 14px; line-height: 22px;" class="">I’m interested in advice to either prevent the problem in the future, or possibly to correct the issue in files that have it.</span></span></font></div><div class=""><font color="#333333" face="Helvetica Neue, Helvetica, Segoe UI, Arial, freesans, sans-serif" class=""><span style="background-color: rgb(255, 255, 255);" class=""><span style="font-size: 14px; line-height: 22px;" class=""><br class=""></span></span></font></div><div class=""><font color="#333333" face="Helvetica Neue, Helvetica, Segoe UI, Arial, freesans, sans-serif" class=""><span style="background-color: rgb(255, 255, 255);" class=""><span style="font-size: 14px; line-height: 22px;" class="">-e</span></span></font></div><div class=""><font color="#333333" face="Helvetica Neue, Helvetica, Segoe UI, Arial, freesans, sans-serif" class=""><span style="background-color: rgb(255, 255, 255);" class=""><span style="font-size: 14px; line-height: 22px;" class=""><br class=""></span></span></font></div></body></html>
