Problem with a pipeline: Internal data flow error/Internal data stream error
 
|
Hello,
I have a strange error with a pipeline. I tried to run this pipeline: demuxer.current_audio ! a52dec mode=2 ! twolame bitrate=224 ! queue max-size-buffers=0 max-size-bytes=0 max-size-time=0 ! muxer. demuxer.current_video ! mpeg2dec ! ffdeinterlace ! ffvideoscale method=10 ! video/x-raw-yuv, width=352, height=576 ! mpeg2enc format=8 aspect=2 bitrate=2304 non-video-bitrate=224 quantisation=8 motion-search-radius=32 reduction-4x4=1 reduction-2x2=1 max-gop-size=15 closed-gop=true force-b-b-p=true intra-dc-prec=10 quant-matrix=1 bufsize=230 interlace-mode=0 ! queue max-size-buffers=0 max-size-bytes=0 max-size-time=0 ! muxer. mplex name=muxer format=8 vbr=true bufsize=230 ! filesink location=filename.mpg filesrc location=filename.vob ! dvddemux name=demuxer This pipeline end with this error: ERRORE dall'elemento /GstPipeline:pipeline0/GstFileSrc:filesrc0: Errore interno nel flusso di dati. (that's the italian translation of internal data flow error) Informazioni di debug aggiuntive: gstbasesrc.c(2543): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc0: streaming task paused, reason not-negotiated (-4) Using GST_DEBUG="*:3" gst-launch-0.10 ... I notice a warning before the error: 0:16:32.129169246 24389 0x7f7f10002090 WARN basetransform gstbasetransform.c:1054:gst_base_transform_acceptcaps:<capsfilter0> transform could not transform video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)576, pixel-aspect-ratio=(fraction)16/15, framerate=(fraction)25/1, interlaced=(boolean)false in anything we support 0:16:32.130138551 24389 0x7f7f10002090 WARN basetransform gstbasetransform.c:1054:gst_base_transform_acceptcaps:<ffmpegscale0> transform could not transform video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)576, pixel-aspect-ratio=(fraction)16/15, framerate=(fraction)25/1, interlaced=(boolean)false in anything we support I tried also to change from dvddemux to ffdemux_mpeg and I received a different error: ERRORE: dall'elemento /GstPipeline:pipeline0/ffdemux_mpeg:demuxer: Internal data stream error. Informazioni di debug aggiuntive: gstffmpegdemux.c(1502): gst_ffmpegdemux_loop (): /GstPipeline:pipeline0/ffdemux_mpeg:demuxer: streaming stopped, reason not-negotiated I tried also to change the decoder from mpeg2dec to ffdec_mpeg2video but the error was the same. If I simply try to demux/mux it with a pipe like: demuxer.current_audio ! queue max-size-buffers=0 max-size-bytes=0 max-size-time=0 ! muxer. demuxer.current_video ! queue max-size-buffers=0 max-size-bytes=0 max-size-time=0 ! muxer. mplex name=muxer format=8 vbr=true bufsize=230 ! filesink location=filename.mpg filesrc location=filename.vob ! dvddemux name=demuxer I receive no errors. I thought that was an error in the original file but the length of the outputs is different: 1) Original file is 3609.84 sec long (but with mplayer I can see till 3611.3, but is only a black screen after the end). 2) The transcoded file that I obtained decoding with mpeg2dec is reported as 3605.14 sec long (but with mplayer I can see till 3608.4). 3) The transcoded file that I obtained decoding with ffdec_mpeg2video is 3605.35 sec long (but with mplayer I can see till 3608.1).

It's a problem with caps your specifying for your required conversion.
gst_base_transform_acceptcaps:<capsfilter0> transform could not transform video/x-raw-yuv, format=(fourcc)I420, width=(int)720, height=(int)576, pixel-aspect-ratio=(fraction)16/15, framerate=(fraction)25/1, interlaced=(boolean)false in anything we support check what is expected and what your supplying and make sure they match.
