Avi decoder
Locked
 
|
Hello everyone !
I'm a newbie here and i'm reading the "Application Development Manual" which is really helpful. But here is my problem : I would like to play an Avi video file. I've seen an example in the manual for an ogg audio file, so i've started from here. But I can't find a working decoder for my avi file.. Anyone can help me plz? Here is my pipeline : pipeline = gst_pipeline_new ("video-player"); source = gst_element_factory_make ("filesrc", "file-source"); demuxer = gst_element_factory_make ("avidemux", "avi-demuxer"); decoder = gst_element_factory_make ("decodebin", "decoder"); conv = gst_element_factory_make ("videoconvert", "converter"); sink = gst_element_factory_make ("autovideosink", "video-output"); Thanks for anyone who can help me ! |

Hard to help if you don't say what format the video inside the AVI is in... but just use playbin2 (or uridecodebin/decodebin2). gst-ffmpeg provides video decoders for many common formats.

Thanks for your reply Stefan =) Hum as I said I'm a newbie, so I don't understand everything yet ^^' If I'm correct, my pipeline should look like this : (?) pipeline = gst_pipeline_new ("video-player"); source = gst_element_factory_make ("filesrc", "file-source"); decoder = gst_element_factory_make ("decodebin2", "decoder"); conv = gst_element_factory_make ("videoconvert", "converter"); sink = gst_element_factory_make ("autovideosink", "video-output"); Am I correct? :o -- View this message in context: http://gstreamer-devel.966125.n4.nabble.com/Avi-decoder-tp3248462p3248494.html Sent from the GStreamer-devel mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Special Offer-- Download ArcSight Logger for FREE (a $49 USD value)!

I tried this code :
play = gst_element_factory_make ("playbin", "play"); g_object_set (G_OBJECT (play), "uri", argv[1], NULL); bus = gst_pipeline_get_bus (GST_PIPELINE (play)); gst_bus_add_watch (bus, my_bus_callback, loop); gst_object_unref (bus); gst_element_set_state (play, GST_STATE_PLAYING); /* now run */ g_main_loop_run (loop); /* also clean up */ gst_element_set_state (play, GST_STATE_NULL); gst_object_unref (GST_OBJECT (play)); But I get the following error : error : URI not valid. don't understand =/ Ps : I want to play the video in the framebuffer (cause I'll use dfbvideosink after, I've my directfb appliaction wrote), and playbin does'nt seems to work for my video =/ |
|
|
the argv[1] has to look like "file:///home/myvideos/video.avi"
|
|
|
Ah thanks that works fine but not in the framebuffer =/ Do you know what could work in the framebuffer? Decodebin maybe? I absolutly need to read my video in the framebuffer cause I need to use DirectFB which use it.. =/ |

Okay I've had a look to older threads and it seems that I need to use dfbvideosink (which I need..).
So I've tried something : pipeline = gst_pipeline_new ("video-player"); source = gst_element_factory_make ("filesrc", "file-source"); decoder = gst_element_factory_make ("decodebin", "decoder"); sink = gst_element_factory_make ("dfbvideosink", "video-output"); But I can't play the video... It stays on a black screen when I run it.. Do I have missed something? a converter maybe? an avidemux? Thanks. |

Maybe a small Bump ? ^^'

I really don't understand where is my error...
I've launch this line : gst-launch filesrc location=test.avi ! avidemux name=demux demux.video_00 ! decodebin ! ffmpegcolorspace ! videoscale ! autovideosink and my video works fine.. But when I do this : //-----------------------------CODE-------------- int main (int argc, char *argv[]) { GstElement *pipe,*src, *dec,*ffm,*scale, *sink; GstMessage *msg; gst_init (&argc, &argv); loop = g_main_loop_new (NULL, FALSE); if (argc < 2) g_error ("Usage: %s <path to file>", argv[0]); pipe = gst_pipeline_new ("pipeline"); src = gst_element_factory_make ("filesrc", "src"); gst_bin_add (GST_BIN (pipe), src); g_object_set (src, "location", argv[1], NULL); //essayer avec dec au lieu de src dec = gst_element_factory_make ("decodebin", "decoder"); gst_bin_add (GST_BIN (pipe), dec); ffm = gst_element_factory_make ("ffmpegcolorspace", NULL); gst_bin_add (GST_BIN (pipe), ffm); scale = gst_element_factory_make ("videoscale", NULL); gst_bin_add (GST_BIN (pipe), scale); sink = gst_element_factory_make ("autovideosink", "sink"); gst_bin_add (GST_BIN (pipe), sink); g_signal_connect (dec, "pad-added", G_CALLBACK (on_new_pad), sink); gst_element_link_many (src,dec,ffm,scale,sink, NULL); if(!pipe || !dec || !sink || !src || !scale || !ffm) g_print ("error...\n"); gst_element_set_state (pipe, GST_STATE_PLAYING); g_print ("Running...\n"); g_timeout_add (5000, get_me_out, NULL); g_main_loop_run (loop); /* Out of the main loop, clean up nicely */ g_print ("Returned, stopping playback\n"); gst_element_set_state (pipe, GST_STATE_NULL); g_print ("Deleting pipeline\n"); gst_object_unref (GST_OBJECT (pipe)); return 0; } //-----------------------------END--------------- I have nothing that shows up !
