I also need to seek for a<br>> specific frame in the file (using external code).<br>> I tried following things:<br>> gst-launch filesrc location=myfile.avi ! decodebin ! ffmpegcolorspace !<br>> ffenc_mpeg2video quantizer=4 gop-size=1 ! ffmux_mpegts ! filesink<br>> location=myfile.ts<br>> This generates a mpg2ts file that I can read with gstreamer, windows media<br>> player (with haali splitter codec), but not VLC...<br>> I tried similar thing using ffmpeg:<br>> ffmpeg -y -i myfile.avi -copyts -an -vcodec mpeg2video -intra -qscale 4 -f<br>> mpegts myfile.ts<br>> This should generate the same output, but it does not. Here I can read the<br>> output file with all media players.<br>> More than that, using command line to seek&extract a frame:<br>> ffmpeg -y -ss 0:4:0.0 -i myfile.ts -vframes 1 -f image2 test.jpg will seek<br>> (almost) correctly and get the frame with ffmpeg-generated file, but not<br>> with gstreamer-generated file.<br>> I thought that gstreamer ffdec/mux plugins were based on ffmpeg, but it<br>> seems it doesn't have correct behavior. Has anyone experienced the same<br>> problems? Or could reproduce it? How can I know which version of ffmpeg the<br>> gst plugins are based on?
