<html><head><style type="text/css"></style></head><body><div style="font-family:'times new roman', 'new york', times, serif;font-size:12pt"><div>Hi all,</div><div>in my attemps to use gstreamer for dealing with mpeg2 ts files, I've ended up with following issues:</div><div>I'm willing to generate mpg2ts files that will be used for analysis whilst beeing generated (this is what ts is good for...). I also need to seek for a specific frame in the file (using external code).</div><div>I tried following things:</div><div><br></div><div>gst-launch filesrc location=myfile.avi ! decodebin ! ffmpegcolorspace ! ffenc_mpeg2video quantizer=4 gop-size=1 ! ffmux_mpegts ! filesink location=myfile.ts</div><div>This generates a mpg2ts file that I can read with gstreamer, windows media player (with haali splitter codec), but not VLC...</div><div><br></div><div>I tried similar thing using ffmpeg:</div><div>ffmpeg -y -i myfile.avi -copyts -an -vcodec mpeg2video -intra -qscale 4 -f mpegts myfile.ts</div><div>This should generate the same output, but it does not. Here I can read the output file with all media players.</div><div><br></div><div>More than that, using command line to seek&extract a frame:</div><div>ffmpeg -y -ss 0:4:0.0 -i myfile.ts -vframes 1 -f image2 test.jpg will seek (almost) correctly and get the frame with ffmpeg-generated file, but not with gstreamer-generated file.</div><div><br></div><div>I thought that gstreamer ffdec/mux plugins were based on ffmpeg, but it seems it doesn't have correct behavior. Has anyone experienced the same problems? Or could reproduce it? How can I know which version of ffmpeg the gst plugins are based on? Looks like the gst formating is not so well-formed...</div><div>I'm really stuck with that problem, and would like to get over it, so any hint is welcomed!</div><div><br></div><div>Best Regards,</div><div>Al</div><div><br></div><div>(my config: XP with winbuild-0.10.4)</div><div style="position:fixed"></div></div><br> </body></html>
