• Error compiling and building DashEncoder code and how to play the .mpd file when generated [closed]

  11 avril 2013, par niuu

  I'm trying to build the DashEncoder code which I downloaded from github https://github.com/slederer/DASHEncoder. Well, I followed all the instructions given in the how to compile dash file. installed Gpac n X264 and compiled both successfully. Then did make of Dashencoder and ran it as ./Dashencoder. But I found some issues in it. Got this log :

  1 file- sintel_trailer_2k_480p24_300kbit.h264 which cannot be opened.

  No .mpd file was created.

  Also I want to know aft creating that .mpd file how will i be able to test it on my android client say media player.

• FFMPEG Growing Input files [closed]

  12 novembre 2024, par user726720

  I'm having issues with piping the ffmpeg out to the ffmpeg input. I have tried as below

  


  ffmpeg -i "y:\3000012936-TXMHD.mxf" -vcodec copy -acodec copy -f mpegts pipe:1 | ffmpeg -re -i pipe:0 -pix_fmt yuv420p -vsync 1 -map 0:v:0 -map 0:a:0 -c:a aac -c:v libx264 -use_template 1 -use_timeline 1 -init_seg_name  "init-stream$RepresentationID$-$Bandwidth$.mp4" -media_seg_name "chunk-stream$RepresentationID$-$Number%05d$.$ext$" -b:v 1500k -b:a 128k -ac 2 -profile:v main -level:v 3.0  -s 1920x1080 -r 25 -vsync passthrough -increment_tc 1 -adaptation_sets "id=0,streams=v id=1,streams=a" -g 100 -keyint_min 100 -seg_duration 5 -frag_duration 5  -dash_segment_type auto -f dash  "stream.mpd"


  


  But I'm getting an error :

  


  


  Conversion failed ! av_interleaved_write_frame() : Broken pipe Error
writing trailer of pipe:1 : Broken pipe

  


  


  The input file is MXF, and output is going to be MPEG DASH. The reason to do the piping is because the input file is a growing mxf file. If i do it without piping the ffmpeg just closes before the mxf file is written completely.
