AVCodecContext' has no member named 'dsp_mask

Here's the complete story. during ./configure step I first received the error,

Code: Select all

configure: error: libavcodec versions 55 and later are not supported yet.

To solve this, I modified the configure.ac file as following:

Code: Select all

diff --git a/configure.ac b/configure.ac index d4e1e89..a5d2e1c 100644 --- a/configure.ac +++ b/configure.ac @@ -2219,12 +2219,7 @@ dnl AC_ARG_ENABLE(avcodec, [ --enable-avcodec libavcodec codec (default enabled)]) AS_IF([test "${enable_avcodec}" != "no"], [ - PKG_CHECK_MODULES(AVCODEC,[libavcodec >= 54.25.0 libavutil >= 51.22.0], [ - AS_IF([test "${enable_sout}" != "no"], [ - PKG_CHECK_EXISTS([libavcodec < 55],, [ - AC_MSG_ERROR([libavcodec version 55 requires --disable-sout.]) - ]) - ]) + PKG_CHECK_MODULES(AVCODEC,[libavcodec >= 53.34.0 libavutil >= 51.22.0], [ PKG_CHECK_EXISTS([libavcodec < 56],, [ AC_MSG_ERROR([libavcodec versions 56 and later are not supported yet.]) ])

When I run ./configure again, this error is gone; However, I receive the following error:

Code: Select all

'AVCodecContext' has no member named 'dsp_mask'

Please pay attention here:
To solve this problem I did the following:

1. I removed ffmpeg 2.0.1 and installed 2.0 instead (maybe this is irrelevant to the problem)
2. As I checked for the installed packages with apt-get I found libavcodec53 and libavcodec53-extra were installed. I removed them.
3. I downloaded the binary library for libavcodec52 and extracted it. inside the usr/lib there is the .so file of the library. I copied that .so file to /usr/lib
4. Now, I again receive the same error and moreover, I cannot install libavcodec with apt-get anymore, I receive this error:

I am stuck, please guide how to resolve this problem and compile vlc source successfully.

I am answering to my own question. As libavcodec 55 and older is required, instead of ffmpeg 2.0.1 I installed FFmpeg 1.2.3 "Magic" which includes libavcodec 54.

libavutil 52. 18.100
libavcodec 54. 92.100
libavformat 54. 63.104
libavdevice 54. 3.103
libavfilter 3. 42.103
libswscale 2. 2.100
libswresample 0. 17.102
libpostproc 52. 2.100

this solved the problem, however, I still get another error which is unrelevant to the topic of this post. I may post itas a new topic.

Cheers,
