* Some SEGMENT might be updates caused by calling gst_pad_set_offset(), which will send the same segment but with an updated offset and/or based field. For those segments, we don't require a DISCONT on the following buffer. * Ignore differences in flags, they aren't relevant for now to figure out whether the segment is an update or not * Ignore difference in 'position', it's only meant for internal usage by elements. * Changes in the end position (stop in forward playback and start in reverse playback) are considering updates Furthermore, also expect a DISCONT flag on the first buffer following a STREAM_START. |

== Gst-Validate The goal of GstValidate is to be able to detect when elements are not behaving as expected and report it to the user so he knows how things are supposed to work inside a GstPipeline. In the end, fixing issues found by the tool will ensure that all elements behave all together in the expected way. The easiest way of using GstValidate is to use one of its command-line tools, located at tools/ directory. It is also possible to monitor GstPipelines from any application by using the LD_PRELOAD gstvalidate lib. The third way of using it is to write your own application that links and uses libgstvalidate. == BUILDING Getting the code: Releases are available at <URL>, download and extract the tarball. If you want to use latest git version, do: git clone <URI> After cloning or extracting from a tarball, enter the gst-validate directory: cd gst-validate The 'master' branch uses gstreamer 1.0, there is a '0.10' branch for gstreamer 0.10. The default is the 'master' branch, if you want to use it for 0.10, do: git checkout --track origin/0.10 Build with: ./autogen.sh --prefix=<installation-prefix> make sudo make install (only if you want to install it) Replace <installation-prefix> with your desired installation path, you can omit the --prefix argument if you aren't going to install it or if you want the default /usr/local. It is possible to use gst-validate CLI tools without installation. == INSTRUCTIONS If you are looking for informations on how to use gst-validate -> docs/validate-usage.txt If you are looking for informations on gst-validate design -> docs/validate-design.txt
