It didn't work for the case where both audio and video streams were present. Then I tried audio only and video only cases. Interestingly, it is working fine for audio only scenario. <br></div><div><br></div><div>But in video only scenario, I am able to generate a few video chunks and then segmentation fault occurs always somewhere inside <span class="s1">mkv_write_flush_packet() of matroskaenc.c. It is not consistently occuring for same memory object, but always happening inside <span class="s1">mkv_write_flush_packet() which is called from webm_chunk muxer's </span>webm_chunk_write_packet() method. </span><br></div><div><br></div><div><span class="s1">I have tried with a keyframe interval of 15secs and 5secs. In both cases, same thing is happening - i.e first few video chunks are generated and then application crashes because of some segmentation fault inside write_packet(). Any help regarding this will be much helpful. Thanks.</span><br></div><div><br></div><div><br></div><div>Regards,<br></div><div>Ravi Kiran B S<br></div><div><br></div></div><div class="zmail_extra"><div id="Zm-_Id_-Sgn1"><div><br></div><div>---- On Wed, 06 Jun 2018 18:53:22 +0530 <b>Carl Eugen Hoyos <ceffmpeg@gmail.com></b> wrote ----<br></div></div><div><br></div><blockquote style="border-left: 1px solid #cccccc; padding-left: 6px; margin:0 0 0 5px"><div><div>2018-06-06 9:01 GMT+02:00, ravikiran.bs <<a target="_blank" href="mailto:ravikiran.bs@zohocorp.com">ravikiran.bs@zohocorp.com</a>>:<br></div><div><br></div><div>> I generate .hdr and .chk files of the actual stream using webm_chunk muxer.<br></div><div>> I am using both the muxers programmatically, not from the command line.<br></div><div><br></div><div>Can you reproduce the issue you see if create the files using the ffmpeg<br></div><div>application from the command line?<br></div><div><br></div><div>Carl Eugen<br></div><div>_______________________________________________<br></div><div>Libav-user mailing list<br></div><div><a target="_blank" href="mailto:Libav-user@ffmpeg.org">Libav-user@ffmpeg.org</a><br></div><div><a target="_blank" href="http://ffmpeg.org/mailman/listinfo/libav-user">http://ffmpeg.org/mailman/listinfo/libav-user</a><br></div></div></blockquote></div><div><br></div></div><br></body></html>
