<div dir="ltr">Hello Thiago Santos-3,<div><br>I just tested last git master (1.5.0.1) and it is working! Thank you so much. <br>I almost cracked my head over this issue while doing numerous of test for last two weeks... thanks.<br><br>Can I ask you follow up question!? <br><br>My streaming application (written in python) will be put in production on short term. I understood that Gstreamer advises to use stable releases for production. At the moment of writing 1.4.5 is the last stable release but with broken mp4/qtmux in it(at least for my usecase).<br><br></div><div>What is usual in such cases like mine? <br>Just use last git master version in production and hope for the best? or<br>Try to use last stable and manually apply needed patches (like qtmux in my case)? or</div><div>Just wait until git master becomes stable?<br><br>Thanks in advance.<br>Best regards,<br><br>Roman S./KPAXIT</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 14 April 2015 at 05:16, Thiago Santos-3 [via GStreamer-devel] <span dir="ltr"><<a href="/user/SendEmail.jtp?type=node&node=4671559&i=0" target="_top" rel="nofollow" link="external">[hidden email]</a>></span> wrote:<br><blockquote style='border-left:2px solid #CCCCCC;padding:0 1em' class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On 04/13/2015 12:54 PM, KPAXIT wrote: <div><div class='shrinkable-quote'><br>> Hi list, <br>> <br>> I'm using following pipeline to record in file: <br>> <br>> gst-launch-1.0 -e --gst-debug=**:4 videotestsrc is-live=true \ <br>> ! queue ! videoconvert \ <br>> ! videorate silent=false \ <br>> ! videoscale \ <br>> !
