• avformat/http: check the auth string contents not the pointer which cannot be NULL

  avformat/http: check the auth string contents not the pointer which cannot be NULL
  It appears this bug originates from a "work in progress" patch from
  
  ffmpeg-devel that was heavily redesigned by and integrated in libav
  And that patch even had a reply and review on the mailing list pointing
  
  out that it had a bug.
  This fixes a deadlock with ffserver
  See : [FFmpeg-devel] [PATCH] Fix HTTP authentication problem for POST actions.
  
       [FFmpeg-devel] [PATCH 1/3] Introduce auth_phase flag, which will be true if authorization needs to be sent, but the type of authorization is not known yet Partial fix #3036
  
       [FFmpeg-devel] [PATCH 2/3] Only add Transfer-Encoding header when not in authorization phase, because server will wait (indefinitely) for data when receiving this header Partial fix #3036
  
       [FFmpeg-devel] [PATCH 3/3] Only allow posting data and/or forcing a 200 code, enabling posting isml chunks, -after- we did a possible first request to get a 403 from the server telling us which type of authentication to apply Final part fix #3036

• FFMpeg copy stream SEI type 162 error

  13 juillet 2015, par Vishal Shah

  I am using FFMpeg to copy an RTSP stream to an RTMP stream. Both of which are network streams. This is the command I am using.

  ffmpeg -re -i rtsp ://url.to/rtsp/stream -c copy -f flv rtmp ://target.rtmp/uri/stream

  I am receiving data on the youtube live control room. But After a point I get an error like this in my FFMpeg console and then the data transfer on youtube live stops.

  SEI type 162 size 1496 truncated at 1280

  Can someone throw light on what this error means and how to resolve it ?

  Note that the RTSP stream is over the network

• x264 on Ubuntu video bad/corrupted

  6 septembre 2013, par Ryzone

  I am trying to use command line x264 to produce a blu-ray compatible file for use in Adobe Encore. For the source file I've tried both ProRes and mpeg2, both 1080p24. Both files import into Encore fine (no transcoding needed which is great) but the ProRes version is pink and grey "static" and the mpeg2 is just a bunch of green/black lines. The exact same files and the exact same commands on my Win7 PC come out fine. I'm only doing a 10 sec sample of the complete 90min movie. I'd love for it to work on Ubuntu cause it is running a new i7 haswell that encodes much quicker than my PC (many hours difference in encoding time)

  Ubuntu 13.04
  
  
  
  x264 0.135.2 f0c1c53<br />
  
  built on Jul 24 2013, gcc: 4.7.3<br />
  
  configuration: --bit-depth=8 --chroma-format=all<br />
  
  x264 license: GPL version 2 or later
  
  
  
  command:
  
      x264 --bitrate 30000 --preset veryslow --tune film --bluray-compat --fps 24000/1001 --force-cfr --bframes 3 --ref 4 --muxer raw --no-weightb --weightp 0 --b-pyramid none --vbv-maxrate 40000 --vbv-bufsize 30000 --level 4.1 --profile high --keyint 24 --min-keyint 1 --open-gop --slices 4 --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --sar 1:1  -o output.264 --input-res 1920x1080 sample.mov

  (if it would work I'd be doing two pass encoding)

  I am able to encode the sample file with ffmpeg to h264 (if that helps).
