stream video with live streaming http using FFmpeg
19 avril 2015, par ranshIs it possible to stream encoded video with http live stream without going through the muxing stage ?
For example can I use http stream with jp2 encoded format (jpeg 2000) without wrapping it first with any muxer ? if not - what can be done instead ?Thank you,

Progressive or Interlaced misinterpreted when transcoding to DNxHD mxf with ffmpeg
19 avril 2015, par OlleHi, don’t know if i am doing it wrong or is there a bug.
Trying to transcode 1080i Video from Quicktime Animation interlaced upper field with a stereo audio to MXF, DNxHD with discreet mono audio channels and video interlaced.
DNxHD = VC-3 op1a 120M.Everything works as a charm except for the end result is being tagged as Progressive ! I can see, when i look at the video, that it is interlaced and good looking, so everything is in order.
But the MXF file is identifying it self as a Progressive video, so our asset management system treat it as a progressive file 1080p and so does the Avid Mediacomposers.
I can’t se the problem with ffprobe but i can in MediaInfo v0.7.69
Se below.Command that i run :
./ffmpeg -i OLLETEST_MANSZELM_ANIMATION.mov -timecode 10:00:00:00 -threads 16 -map 0:0 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -vcodec dnxhd -b:v 120M -acodec pcm_s24le -ar 48000 -flags +ildct -y test.mxfThe transcoded file run with media info reports this strange result.
Scan type : Progressive
Original scan type : Interlaced
Original scan order : Top Field Firstseems as
-flags +ildctdon’t affect Scan type :The output from ffmpeg :
Olles-MacBook-Pro-2:NoBackUp olso$ ./ffmpeg -i OLLETEST_MANSZELM_ANIMATION.mov -timecode 00:10:00:00 -threads 16 -map 0:0 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -vcodec dnxhd -b:v 120M -acodec pcm_s24le -ar 48000 -flags +ildct -y test.mxf

ffmpeg copyts to preserve timestamp
13 avril 2015, par BalaI am trying to modify an HLS segment transport stream, and preserve its start time with ffmpeg. However the output does not preserve the input file’s start_time value, even if -copyts is mentioned. Here’s my command line :
ffmpeg -i fileSequence1.ts -i x.png -filter_complex '[0:v][1:v]overlay[out]' -map '[out]' -map 0:1 -acodec copy -vsync 0 -vcodec libx264 -streamid 0:257 -streamid 1:258 -copyts -profile:v baseline -level 3 output.tsThe start_time value is delayed about 2 seconds consistently.
/Users/macadmin/>ffmpeg -y -v verbose -i fileSequence0.ts -map 0:0 -vcodec libx264 -copyts -vsync 0 -async 0 output.ts
