gstreamer : record a stream while playing
 
|
Hello all,
If i want to record a stream while playing, i think that I can use this pipeline : gst-launch-1.0 filesrc location=/home/sefram/TS/Samsung.ts !
queue ! typefind ! tee name=t t. ! decodebin ! queue ! kmssink t.
! queue ! filesink location=/home/firsttry.ts
this pipeline should do this :
/ [ decodebin |
queue | kmssink ] (playing_branch)
but it doesn't work the pipeline never start : gst-launch-1.0 filesrc
location=/home/sefram/TS/Samsung.ts ! queue ! typefind ! tee
name=t t. ! decodebin ! queue ! kmssink t. ! queue ! filesink
location=/home/firsttry.ts whereas if I delete the recording branch, it works correctly. root@cl-som-imx8:~# gst-launch-1.0 filesrc
location=/home/sefram/TS/Samsung.ts ! queue ! typefind ! tee
name=t t. ! decodebin ! queue ! kmssink t. ! queue ! filesink
location=/home/firsttry.ts If someone has an idea about the problem...
Thanks

Hi
you probably need a `queue`-Element in each branch after the tee element. -Peter Am 05.02.19 um 16:40 schrieb Duchassin Frederic: > Hello all, > > > If i want to record a stream while playing, i think that I can use this > pipeline : > > gst-launch-1.0 filesrc location=/home/sefram/TS/Samsung.ts ! queue ! > typefind ! tee name=t t. ! decodebin ! queue ! kmssink t. ! queue ! > filesink location=/home/firsttry.ts > > > this pipeline should do this : > > > / [ decodebin | queue | > kmssink ] (playing_branch) > filesrc | queue | typefind | tee > \ [ queue | filesink ] > (recording_branch) > > > but it doesn't work the pipeline never start : > > gst-launch-1.0 filesrc location=/home/sefram/TS/Samsung.ts ! queue ! > typefind ! tee name=t t. ! decodebin ! queue ! kmssink t. ! queue ! > filesink location=/home/firsttry.ts > Setting pipeline to PAUSED ... > Pipeline is PREROLLING ... > > ====== AIUR: 4.3.5 build on Jan 21 2019 17:47:10. ====== > Core: BLN_MAD-MMLAYER_MPG2PARSER_04.05.16 build on Sep 14 2017 > 02:37:53 > file: /usr/lib/imx-mm/parser/lib_mpg2_parser_arm_elinux.so.3.1 > > whereas if I delete the recording branch, it works correctly. > > root@cl-som-imx8:~# gst-launch-1.0 filesrc > location=/home/sefram/TS/Samsung.ts ! queue ! typefind ! tee name=t t. ! > decodebin ! queue ! kmssink t. ! queue ! filesink location=/home/firsttry.ts > Setting pipeline to PAUSED ... > Pipeline is PREROLLING ... > > ====== AIUR: 4.3.5 build on Jan 21 2019 17:47:10. ====== > Core: BLN_MAD-MMLAYER_MPG2PARSER_04.05.16 build on Sep 14 2017 > 02:37:53 > file: /usr/lib/imx-mm/parser/lib_mpg2_parser_arm_elinux.so.3.1 > ^Chandling interrupt. > Interrupt: Stopping pipeline ... > ERROR: pipeline doesn't want to preroll. > Setting pipeline to NULL ... > Freeing pipeline ... > root@cl-som-imx8:~# gst-launch-1.0 filesrc > location=/home/sefram/TS/Samsung.ts ! queue ! typefind ! tee name=t t. ! > decodebin ! queue ! kmssink > Setting pipeline to PAUSED ... > Pipeline is PREROLLING ... > > ====== AIUR: 4.3.5 build on Jan 21 2019 17:47:10. ====== > Core: BLN_MAD-MMLAYER_MPG2PARSER_04.05.16 build on Sep 14 2017 > 02:37:53 > file: /usr/lib/imx-mm/parser/lib_mpg2_parser_arm_elinux.so.3.1 > ------------------------ > Track 00 [video_0] Enabled > Duration: 0:01:58.601811000 > Language: und > Mime: > video/x-h265, parsed=(boolean)true, alignment=(string)au, > stream-format=(string)byte-stream, width=(int)3840, height=(int)2160, > framerate=(fraction)30/1 > ------------------------ > ------------------------ > Track 01 [audio_0] Enabled > Duration: 0:01:58.528000000 > Language: und > Mime: > audio/mpeg, mpegversion=(int)4, channels=(int)2, > rate=(int)48000, bitrate=(int)192000 > ------------------------ > ====== VPUDEC: 4.3.5 build on Jan 21 2019 17:47:26. ====== > wrapper: 3.0.0 (VPUWRAPPER_ARM64_LINUX Build on Jan 21 2019 > 17:02:05) > vpulib: 1.1.1 > firmware: 1.1.1.65535 > > ====== BEEP: 4.3.5 build on Jan 21 2019 17:47:16. ====== > Core: AAC decoder Wrapper build on Dec 7 2017 18:13:51 > file: /us[ 1437.616914] alloc_contig_range: 42 callbacks suppressed > r/lib/imx-mm/audio-codec/wrap/lib[ 1437.616918] alloc_contig_range: > [5eb00, 5f9d5) PFNs busy > _aacd_wrap_arm_elinux.so.3 > 1437.631555] alloc_contig_range: [5ec00, 5fad5) PFNs busy > 3mCODEC: BLN_MAD-MMCODECS_AACD_AR[ 1437.639743] alloc_contig_range: > [5ec00, 5fbd5) PFNs busy > M_03.09.00_ARMV8 build on Sep 20[ 1437.648085] alloc_contig_range: > [5ec00, 5fcd5) PFNs busy > 2017 15:02:50. > [ 1437.656130] alloc_contig_range: [5ec00, 5fdd5) PFNs busy > [ 1437.662854] alloc_contig_range: [5f000, 5fed5) PFNs busy > [ 1437.668731] alloc_contig_range: [5f000, 5ffd5) PFNs busy > [ 1437.674615] alloc_contig_range: [5f000, 600d5) PFNs busy > [ 1437.681140] alloc_contig_range: [5f000, 601d5) PFNs busy > [ 1437.687145] alloc_contig_range: [5f000, 602d5) PFNs busy > Pipeline is PREROLLED ... > Setting pipeline to PLAYING ... > New clock: GstSystemClock > > If someone has an idea about the problem... > > > Thanks > > > Frederic > > > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel > gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi,
Even with a queue in each branch it doesn't work : gst-launch-1.0 filesrc location=/home/sefram/TS/4kfile.ts ! queue
! typefind ! tee name=t t. ! queue ! decodebin ! queue !
kmssink t. ! queue ! filesink
location=/home/sefram/TS/essai.ts Frederic

That would prevent the pipeline from prerolling. Try unsetting the limit on the queue that feeds into filesink with queue max-size-bytes=0 max-size-time=0 max-size-buffers=0 Cheers Tim -- Tim Müller, Centricular Ltd - http://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Hi Tim,
You're completely right! Many many thanks for your help. Great !!!

Hello All,
Just a new question in relation with this pipeline : Is it possible to add all the gstreamer sinks to my pipeline AND only link one branch. That's to say, just link the record branch. The decode branch is in pipeline but not linked. At this point, my first test show that it doesn't work.

If you put in sinks that don't receive data at the beginning, the pipeline will not preroll (start up). You can work around that by setting these sinks to async=false.

Hi Tim,
I have solve my problem by adding/removing elements from my pipeline. It's not very very beautiful because all elements are created in my main program and it lead to referencing them before removing from the pipeline (because i would like to keep these elements).
