#40829: ffmpeg 2.0.2 - ffv1 codec is bogus --------------------------------+---------------------- Reporter: andre.dos.anjos@… | Owner: devans@… Type: defect | Status: new Priority: Normal | Milestone: Component: ports | Version: 2.2.0 Resolution: | Keywords: Port: ffmpeg | --------------------------------+---------------------- Changes (by macsforever2000@…): * cc: jeremyhu@… (added) * owner: macports-tickets@… => devans@… * keywords: codec ffv1 => Old description:
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
