trying to play corrupted mpeg-ts video using android video view
20 avril 2015, par asafbi am having issue playing partial content of mepg-ts files
the video files cannot be changed / reformatted / remuxed etc
server setup :
contains mpeg-ts video files with h264/acc
has script that when requested using parameters returns on of the videos "cut"
according to parameters-player :
(i have no problem playing the full videos "uncut")
i am trying to play this using android videoview,
during researching i have found that vlc is the only player able to play the "cut" videos (aka windows mediaplayer, google exoplayer and chrome html5 video player are unable to play)
running vlc at debug mode revealed error when playing cut video :
ts error : MPEG-4 descriptor not found
remuxing the partial content using ffmepg fixes the videosolutions tried till now :
1.tried remuxing on the fly using android MediaExtractor and MediaMuxer - but then found out that its not possiable doing that on the fly and anyway that MediaExtractor is unable to open "cut" video
2.tried getting the first 10K of the full video and then append them to the rest of the "cut" video - the behvior stays the same (vlc able to play while rest wont)video files info :

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 concat demuxer - how to make file formats compatible ?
10 avril 2015, par user206481I need to automate mp4 concatenation server-side and I’m using FFMPEG. I will get uploads of mp4 files and I want to attach a Title.mp4 and End.mp4 to each one. I am also overlaying a soundtrack (the input videos do not have sound) There is a potential high server load so I’d like to do it as efficiently as possible using ffmpeg’s concat demuxer to avoid re-encoding the video.
After receiving samples of each file, I am not successful and I believe it is due to mismatched file formats. My result has good Title.mp4 and audio, then when the sample uploaded mp4 is supposed to play there is garbled green/pink/red pixels on the top half of the video, then the End.mp4 plays fine. Here is my ffmpeg command and output :
$ ffmpeg -f concat -i <(printf "file '%s'\n" Title.mp4 Sample.mp4 End.mp4) -i SoundTrack.wav -c:v copy -strict -2 -y Out.mp4

Tagged date : UTC 1970-01-01 00:00:00I’m pretty sure it’s the mp42 vs isom Codec ID’s, and potentially the constant vs variable frame rates. I can’t change the input mp4’s but I know their format will stay the same. How can I reformat the Title and End mp4’s to match the input mp4 files so I can use ffmpeg concat demux ?
