#40829: ffmpeg 2.0.2 - ffv1 codec is bogus
-------------------------------+--------------------------------
 Reporter:  andre.dos.anjos@…  |      Owner:  macports-tickets@…
     Type:  defect             |     Status:  new
 Priority:  Normal             |  Milestone:
Component:  ports              |    Version:  2.2.0
 Keywords:  codec ffv1         |       Port:  ffmpeg
-------------------------------+--------------------------------
 Apparently, ffmpeg (at least version 2.0.2) has a mal-functioning "ffv1"
 codec. The attached program replicates the problem. It was extracted from
 the example section of the ffmpeg manual (http://ffmpeg.org/doxygen/2.0
 /doc_2examples_2muxing_8c-example.html), slightly modified to force the
 FFV1 codec by replacing lines 419-421 (with video_st = add_stream(oc,
 &video_codec, AV_CODEC_ID_FFV1)). It used to at least, before the updated
 to 2.0.

 Compiling and linking:

 clang -I/opt/local/include test.c -L/opt/local/lib -lavutil -lavcodec
 -lavformat -lswscale -lswresample -o ffmpeg_test

 Running:

 ./ffmpeg_test test.avi
