I also need to seek for<br>>> 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.
