Problems with VOB file from DVD Recoder
Locked
 
|
I tried posting this via Nabble last night, seems they've not realized the list has moved :(
I'm having issues with playback of the VOB files from a DVD Recorder (finalized disk) when using Gstreamer. Using the pipeline: gst-launch filesrc location=./VTS_01_5.VOB ! mpegdemux ! mpeg2dec ! xvimagesink Works fine if the file is from an authored (non-encrypted) DVD+/-R disk. But if the file is from a finalized disk recorded using a standalone DVD Recorder it doesn't play: Setting pipeline to PAUSED ... Pipeline is PREROLLING ... Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock Got EOS from element "pipeline0". Execution ended after 18810910555 ns. Setting pipeline to PAUSED ... Setting pipeline to READY ... Setting pipeline to NULL ... Freeing pipeline ... There seems to be a gstreamer sort of work-around as the gstreamer based Totem media player can play the DVD Recorder VOB file, but it reports the length as 1 second, seeking is totally broke, but it does playback correctly. Any clues? I'd like to be able to use the filesrc to access individual frames of the file via appsink for analysis but have no idea how to get beyond this issue. OTOH, the gstreamer based Pitivi v0.13.4 editor totally chokes on the file putting it on the timeline as only one second long. _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hello,
You could try using gst-launch filesrc location=./VTS_01_5.VOB ! decodebin2 ! xvimagesink -v and see what elements are used , that will give you a clue what totem does internally. About the timeline being shown as 1 sec maybe either the timestamping isnt done properly or bug in demuxer.

To: Discussion of the development of and with GStreamer <[hidden email]> Thanks, I did this and it plays nicely, but the verbiage doesn't really help me understand anything: gst-launch filesrc location=./VTS_01_1.VOB ! decodebin2 ! xvimagesink -v Setting pipeline to PAUSED ... /pipeline0/decodebin20/typefind.src: caps = video/mpeg, systemstream=(boolean)true, mpegversion=(int)2 Pipeline is PREROLLING ... /pipeline0/decodebin20/flupsdemux0.sink: caps = video/mpeg, systemstream=(boolean)true, mpegversion=(int)2 /pipeline0/decodebin20/multiqueue0.sink0: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /pipeline0/decodebin20/multiqueue0.sink1: caps = audio/x-private1-ac3 /pipeline0/decodebin20/multiqueue0: max-size-buffers = 5 /pipeline0/decodebin20/multiqueue0: max-size-time = 2000000000 /pipeline0/decodebin20/multiqueue0: max-size-bytes = 2097152 /pipeline0/decodebin20/multiqueue0.src0: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /pipeline0/decodebin20/multiqueue0.src1: caps = audio/x-private1-ac3 /pipeline0/decodebin20/a52dec0.sink: caps = audio/x-private1-ac3 /pipeline0/decodebin20/a52dec0.src: caps = audio/x-raw-float, endianness=(int)1234, width=(int)32, channels=(int)2, rate=(int)48000, channel-positions=(GstAudioChannelPosition)< GST_AUDIO_CHANNEL_POSITION_FRONT_LEFT, GST_AUDIO_CHANNEL_POSITION_FRONT_RIGHT > /pipeline0/decodebin20/mpeg2dec0.sink: caps = video/mpeg, mpegversion=(int)2, systemstream=(boolean)false /pipeline0/decodebin20/mpeg2dec0.src: caps = video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)480, pixel-aspect-ratio=(fraction)8/9, framerate=(fraction)30000/1001 /pipeline0/xvimagesink0.sink: caps = video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)480, pixel-aspect-ratio=(fraction)8/9, framerate=(fraction)30000/1001 /pipeline0/decodebin20.src0: caps = video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)480, pixel-aspect-ratio=(fraction)8/9, framerate=(fraction)30000/1001 /pipeline0/decodebin20.src0.proxypad1: caps = video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)480, pixel-aspect-ratio=(fraction)8/9, framerate=(fraction)30000/1001 Pipeline is PREROLLED ... Setting pipeline to PLAYING ... New clock: GstSystemClock Since DVD Recorders work to a "standard" it would seem by definition to be a bug in the demuxer. Seeking in VLC does work but its full of video mosaic artifacts while "scrubbing" to find a region of interest. None of the gstreamer based applications seem to be able to seek in this file, although they can seek smoothly in the VOB file from an "authored" DVD disk. However I should be able to simply use decodebin2 to feed the data to my appsink so this could be a usable solution for me. Ultimately I'd like to have seeking and perhaps even frame by frame forward/backward interaction, but I'm a long way from there right now. _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Wally,
You have to debug whats wrong and/or file a bug with the debug logs and your input file.
