Hi,

on gentoo with ffmpeg version 2.2.5 the symbol AVCODEC_MAX_AUDIO_FRAME_SIZE is missing.
According to mpenkov/ffmpeg-tutorial#13 each project has to define this for themselves.
I made a patch:
--- a/src/lavfmuxer.cpp
+++ b/src/lavfmuxer.cpp
@@ -40,6 +40,12 @@ extern "C" {
#define CODEC_TYPE_AUDIO AVMEDIA_TYPE_AUDIO
#endif

+/* libavcodec >= 2.2.5 does not define this anymore */
+#ifndef AVCODEC_MAX_AUDIO_FRAME_SIZE
+# define AVCODEC_MAX_AUDIO_FRAME_SIZE 192000 // 1 second of 48khz 32bit audio
+#endif
+
+

The first German translation is done.
Because I have no permission to write, I'll have to send the dvbcut_de.ts via e-mail.

Regards Roland

Hi, using Qt 4.8.0, I had to add the following two includes to dvbcut.cpp to have it successfully compiled on my XUbuntu 64-bit machine:

include "errno.h"

include "math.h"

I'd like to contribute to this project f.e. by giving it a german translation.

regards Roland

Hello all,

the commit abf4434 introduces function decode_audio3(...) which uses av_frame_alloc() and av_frame_free().
I have ffmpeg version 1.2.6 installed by my distribution which does not know the symbols.
Over here LIBAVCODEC_VERSION_INT is defined as (54,92,100).

I made a patch similar to the one posted here
http://stackoverflow.com/questions/24057248/ffmpeg-undefined-references-to-av-frame-alloc

I am trying to compile this in Qt Creator 2.5.2 with Qt 4.8.1 on Ubuntu 12.04.

I get this error:
No rule to make target ../../dvbcut-qt4/src/version.h', needed bydvbcut.o'. Stop.

When I run ./setversion.sh on the terminal manually it goes on but then says:
/…/dvbcut-qt4/src/lavfmuxer.cpp:52: Fehler:'avformat_alloc_output_context2' was not declared in this scope

I have libavformat-dev 0.8.6 installed.
