• Re-creating/matching ffmpeg settings

  8 novembre 2013, par Pete Helgren

  I have an MP4 file that plays pretty much on every browser using either HTML5 or flash fallback (using mediaelement.js). I also have a series of additional video files that I would like to have "match" the one file that does play consistently but I haven't been able to match the ffmpeg settings so it produces a like file. I used ffprobe and got the following results on the file that plays successfully :

  Following a few guides I found online, I am using the following ffmpeg settings :

  ffmpeg -i {input file name} -y -acodec aac -ac 2 -strict experimental -ab 64k -s 320x240 -vcodec libx264 -pix_fmt yuv420p -preset slow -profile:v baseline -level 30 -maxrate 300k -bufsize 600k -b:v 300k -f mp4 -threads 0 -movflags +faststart {output file name}

  That command produces the following output :

  ffmpeg -i "testin.mp4" -y -acodec aac -ac 2 -strict experimental -ab 64k -s 320x240 -vcodec libx264 -pix_fmt yuv420p -preset slow-profile:v baseline -level 30 -maxrate 300k -bufsize 600k -b:v 300k -f mp4 -threads 0 -movflags +faststart testout.mp4

  The one problem with the incantation above is that on iPad's and iPhones and some Android tablets all you hear is the audio with no video. But the file listed above (contents of the ffprobe) does not have that problem, it WILL play on an iPad, iPhone, Android tablet. I researched causes for "audio, no video" and the recommendations were all over the deck. But, the file listed in the ffprobe DOES play, so if I can match those settings described by the ffprobe for all of the other videos, they should play consistently as well. My challenge is to match the ffprobe settings using ffmpeg and there doesn't seem to be a 1 to 1 match between what I see in ffprobe and the corresponding settings in ffmpeg (a nice utility would be to have ffprobe output the ffmpeg settings that could be used to create a file of similar format).

  I walked through the ffprobe documentation but couldn't find anything that would produce a format that could be used as input to ffmpeg. Suggestions ?

• FFMPEG encode video with alpha channel to flv

  29 octobre 2013, par tree

  I'm trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can't seem to either

  1. find a codec that is supported
  2. find one that actually maintains the alpha

  Does anyone know how to set that up ?

  Thanks,

  ffmpeg -i abc_btr_1280x800_Takeover.mov -vcodec flv -pix_fmt yuv444p -s 1280x800 test4.flv

  here is the report...

• Set timeout on ffmpeg process

  30 octobre 2013, par Thomas Vervik

  Sometims ffmpeg never completes, and thereby preventing conversions of other videos in the queue. Is it possible to set some sort of timeout in ffmpeg such that it terminates if it isnt finished within some given time, example 5 min

  My command looks like this today :

   ffmpeg -i /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141 -y -r 24 -ar 22050 -f mov -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.mov -ar 22050 -b 1500k -vcodec libtheora -acodec libvorbis -f ogg -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141.ogg -ar 22050 -vcodec libx264 -profile baseline -vf [in]transpose=1[rt0],[rt0]scale=iw*480/ih:480[sc0],[sc0]pad=640:480:140[pd0],movie=/srv/bsafe/tomcat7/webapps/ROOT/resources/images/logo_watermark.png [wm],[pd0][wm] overlay=W-w-140:0[out] /home/tomcat/bsafevideo/1efef9daa7f5000ed83d67f6fbd0e7d9/aad5adc307c4dd7e457509423a7f3734/69451c31cd592e86138423f6849d8141_mp4.mp4

  UPDATE. Thanks LordNeckBerd, you pointed me in right direction !

  So I see now its kind of not ffmpeg really hanging, the issue is that my java code which reads the inputstream from the linux process will block since ffmpeg never returns a end of line, which I see now when Im running the command. This is the blocking line, it waits for more input from me.

  So its two issues here now. First is why this particular conversion is failing, and second, how to make sure ffmpeg is not making this (for my Java process) blocking command asking for more input.
