Description (last modified by Carl Eugen Hoyos)

Dear all:

I build ffmpeg 1.2 for Android 4.1.2 tablet (NEON is enabled). When I use this library to decode a .3gp file (video is MPEG4 and audio is AAC)， it crash. I tested some files, I found if the video is MPEG4, it always crash. Does anybody help me? Thanks.

Keywords:	crash added

What is libffmpeg.so ? To the best of my knowledge, compilation never produced such a file.

Please test current git head and please test ffmpeg (the application) if it allows to reproduce the crash.
Then please use gdb for a useful backtrace and point us to a sample that allows to reproduce the issue.

Replying to cehoyos:

What is libffmpeg.so ? To the best of my knowledge, compilation never produced such a file.

Please test current git head and please test ffmpeg (the application) if it allows to reproduce the crash.
Then please use gdb for a useful backtrace and point us to a sample that allows to reproduce the issue.

libffmpeg.so is produced by the following instruction. It consists of ffmpeg library(libavcodec/libavcodec.a libavformat/libavformat.a libavutil/libavutil.a libswscale/libswscale.a libswresample/libswresample.a) and some system library.

comment:4 by Carl Eugen Hoyos, 13 years ago

Since this is not supported, please test with ffmpeg (the application).

comment:5 by Felix Yang, 13 years ago

I found the reason. When I set AVCodecContext:lowres to 3, it always crash in MPEG4 decoding, but it's fine in H.264. When I set AVCodecContext:lowres to 0, it is OK. I trace the code I find if the lowres is not 0 , MPV_motion_lowres will be called. MPV_motion_lowres will call ff_put_h264_chroma_mc2_neon and it crashes. I don't know is there any limitation in ff_put_h264_chroma_mc2_neon?

Priority:	normal → important

Please test ffmpeg (the application) and please provide a backtrace etc. as explained on http://ffmpeg.org/bugreports.html

Also reproducible with higher resolutions, lowres 2 works fine here.
